Accessing a confined space takes planning to ensure that everyone who enters, exits and works in the space can do so safely. Read on for tips from 3M on how-to prepare for confined space access. 

By the time you are accessing the confined space, a hazard assessment has been completed, but if not, one needs to be conducted to ensure all hazards have been identified. This thorough review will help you identify the right equipment to access the confined space properly. It also is essential to have proper training that will allow you to understand and identify the risks associated with this specific kind of work and then mitigate these risks and hazards effectively. Finally, before any work can begin, air quality should be tested to make sure the conditions are suitable for entry.

As you can see, there is a lot of planning and steps that must be conducted before accessing a confined space on your job site. This includes making sure that you have identified a primary point of contact and resource for issues pertaining to confined space entry. Often this may be the HSE management as well as the supervisor. Let’s explore some of the steps to take before accessing any confined space on your job site.

Confined Space Access | Hazard Assessment

Every single time a confined space is going to be accessed, you need to review the risk assessment for that space and validate that there aren’t new risks or hazards because of the work being done or events happening around the space. This reassessment ensures the workers entering the space will be protected properly based on these current conditions. The conditions often change and, therefore, this assessment should be constantly updated. This may include a variety of issues, such as unsafe levels of gas requiring respiratory protection, the presence of flammable substances, loud noises requiring hearing protection, and control of all energy sources (lock-out/tag-out).

This part of planning should also include a pre-work (or pre-access) briefing. During this part of the preparation, all the work, the time it will take, and emergency protocols that may be needed should be reviewed so everyone is on the same page.

Confined Space Access | Air Monitoring

Prior to any confined space entry, you are required to carry out air testing when it is known (e.g. from information on a previous hazard assessment or chemicals used in a previous activity in the space) that the atmosphere in the confined space might be contaminated or to any extent unsafe to breathe. Gas detection instruments should be checked to make sure they are working properly per product user instructions.

Most confined space air monitoring is accomplished using a four-gas analyzer. This checks the atmosphere for oxygen concentration and to determine the presence of various hazardous fumes, gases, vapors and particulates. Based on your hazard assessment, there may be a need for gas-specific monitors to determine lower-level concentrations that may be present.

Confined Space Access | Equipment Needed for Access

Without the proper equipment and training, safety and efficiency may be compromised and rescuing someone may be delayed if a problem does arise. 

Think about it this way: confined space access, hercules slr, securing, lifting and rigging

 

 

 

 

 

The key people involved in entries into confined spaces are the entrant, attendant, supervisor and rescue teams. All these participants require thorough training on the right equipment to minimize the risk of injury. Rescue plans that outline each step regarding how to work in the space and how to react if a problem occurs must be in place and be well-known by all parties in order to minimize the time required in case the need to rescue, remove or retrieve is needed.

Now think about it this way – this is how you can be prepared if you think it through:

confined space access, hercules securing, lifting and rigging

 

 

 

 

 

 

 

The various types of confined spaces may all have different access points, involving vertical or horizontal entry and these will require different access equipment. Examples include a tripod, davit, pole hoist, side entry system, winch, and SRL retrieval. Having the right equipment in good working order and proper training on how to use these solutions for entrants can help prevent risk and in some instances, prevent the need for anyone else to enter if a rescue does become necessary.

The equipment used for access can be your initial rescue equipment. However, for certain entries, rescue teams may want specialized equipment, which should be available nearby during access work and be in good working order. Inspecting this equipment and making sure the rescue team is trained on rescue procedures and how to use this equipment is vital. They also should be trained in resuscitation procedures in the case that becomes necessary. Reviewing a rescue plan before anyone accesses the space should also be a part of your plan.

Confined Space Access | Additional Tips for Accessing a Confined Space

Besides conducting a thorough hazard assessment, air monitoring and making sure the right equipment is being used correctly, here are some additional steps you should keep in mind when conducting confined space work:

  • All entrants for permit and non-permit work, as a best practice, should wear a full body harness. The harness should be designed for the intended use in the space.
  • Authorized entrants who enter a permit space must wear a chest or full body harness with a retrieval line attached to the center of their backs near shoulder level or above their heads connected to a fixed point outside the permit space. The best practice is that the other end of the retrieval line is attached to a mechanical advantage device.
  • Permit spaces greater than five feet deep require a pre-rigged retrieval system with mechanical advantage. It is very important that users be trained on the use of the retrieval system. However, always consider a mechanical advantage regardless of the depth of the confined space.
  • All individuals have the authority to stop work for any confined space entry where they observe that the requirements of the safety program that the job site has put in place are not being followed correctly. This includes the attendant, entrant and supervisor.
  • The confined space attendant who will be present outside the space the whole time while workers access and work inside should be able to maintain some sort of communication with the workers inside the space. Because the people inside the space may not be visible, other means of communication (such as an electronic voice communication system) should be considered.

Once the work is completed, everyone should review what worked well, inspect all the equipment used to see what needs repairs or should be replaced. You should also update the risk assessment with your findings for future workers who may need to access the space.

There is a lot to consider when accessing confined spaces. If you’re not sure where to start, call your local Hercules SLR and book your fall protection demo now.

Fall Protection Safety: What’s your IQ?

fall protection safety quiz hercules securing, lifting and rigging

Think you know how to stay safe at heights? Maybe you’ve read our fall protection glossary and think you’re an expert? Now’s your time to prove it—Take our fall protection safety quiz and find out if you have a high IQ, or if you have a little more training to do. 

Think you have what it takes? Find out below! 

FALL PROTECTION SAFETY | TAKE THE QUIZ

0%

How many injuries occur each year in Canada due to dropped objects?

Correct! Wrong!

Over 27,000 injuries occur due to falling objects each year in Canada—These are just the reported incidents.

True or false? You only need fall protection equipment if you're working at exceptional heights, like on a bridge or skyscraper.

Correct! Wrong!

Fall protection equipment, particularly fall protection for tools is required for work at heights of 3-metres or more.

The term 'arresting force' means:

Correct! Wrong!

Arresting force means the force transferred to the body when a fall is arrested—this is also known as fall arrest force. You can reduce arresting force by using energy absorbers if your lanyard could injure you.

Safety harnesses should always be tried on before purchasing

Correct! Wrong!

You should always try on your safety harness before you purchase. It should fit well, be comfortable and meet provincial regulations.

A safety harness is still safe to use if the webbing is torn a little bit, as long as it's not around the D-ring.

Correct! Wrong!

Webbing varies from harness to harness, however, make sure to choose a harness with sturdily-constructed webbing—If the harness has any burns, tears, holes or frayed webbing. The material should slide through hardware without catching/snagging. If it does, take your harness out of service. Safety harnesses are meant to be used in

How should padding on your safety harness fit?

Correct! Wrong!

Like you probably learned from earlier questions, comfort is important when it comes to fall protection equipment. Padding on a safety harness should be easy to handle, pliable and easily adjustable. Padding must also be able to withstand harsh weather and corrosive conditions, so it's important to select padding that's both breathable and durable.

ALL safety harnesses should come with instructions for best-use.

Correct! Wrong!

Thought it might sound common-sense, all safety harnesses should include tips for applications, instructions and guidelines for using accessories and hardware. Be sure it meets CSA guidelines for your intended application.

How many CSA classifications are there for full-body harnesses?

Correct! Wrong!

There are 5 CSA (Canadian Standards Association) standards for full-body harnesses. These are: Class A, Class AD Suspension and Controlled Descent, Class AE Limited Access, Class AL Ladder Climbing and Class AP Work Positioning.

Items only usually fall from heights when they're unsecured.

Correct! Wrong!

Tools and other items are dropped from heights for a number of reasons—While inadequately-stored or secured tools are the third leading cause of dropped tools from heights, inadequate risk assessment and human factors (poor behaviour, complacency) are the top 2 causes.

Nobody actually dies from falling at work

Correct! Wrong!

VERY false—Over 14,000 Canadian workers are injured each year from falls, and over 40 each year are killed from falls at heights.

What's your Fall Protection Safety IQ?
50%—You've got some work to do!
You're halfway there, but you've got some work to do—Hopefully you're not planning to work at heights anytime soon!
0-10%—Yikes, please don't work at heights anytime soon.
You're not quite there—At all. If you work at heights, we recommend taking some fall protection training to learn more.

WAREHOUSE WORSHIP: HOW OUR CENTRAL DISTRIBUTION CENTRE IS LEADING THE INDUSTRY

HERCULES CENTRAL DISTRIBUTION CENTRE: WHAT WE DO

You’re probably reading this on a computer or mobile phone that at one point, was probably sitting somewhere in a warehouse. In 2019, warehouses are a huge part of nearly every industry but we often don’t consider where our things live before they get to us, or exactly what goes into running a smooth, successful warehouse operation. We’re here to help. 

Hercules’ Central Distribution Centre (DC) in Long-Sault, Ontario has the largest inventory of securing, lifting and rigging equipment under one roof in Canada. We’re also the only Central Distribution Centre (DC) warehouse in the securing, lifting and rigging industry that supplies products on a national-scale to our 20+ branches and ship directly to customers. The Hercules DC is in Cornwall on the 401 highway, sandwiched right between Montreal and Toronto and close to a border-crossing into the United States, as well. 

So, what exactly does it take to operate our DC? Luckily, we know just the guy. Terry Bartlett, Hercules’ Central Distribution Manager shares what he’s learned over his career, and what how he and his team run our DC like a well-oiled machine.  

hercules central distribution warehouse staffHERCULES’ WAREHOUSE: TEAM PLAYERS 

Terry Bartlett has been in distribution and material handling industries for over 20 years. Terry started as a Rig Technician at Hercules SLR in Montreal, quickly moving into a leading roles first as a Production Supervisor, then to Floor Manager. When Hercules decided to open a distribution center 3 years ago, Terry practically leaped at the opportunity to help the team establish operations. Over the past 6 years, Terry’s used his knowledge of Hercules and his distribution experience to set-up, recruit and make operations ultra efficient as our Central Distribution Manager. 

Terry can’t do it all alone—A hard-working team is essential to a well-run DC. Tim Bingley, Nick O’Brien and Jamie Plumadore have been part of the DC warehouse team for two years. They help Terry with basically all aspects of running the DC warehouse, including creating and setting policies & procedures and creating a culture that can continuously improve, keep up and grow with industry trends. 

As our business grows, so does the DC team. The DC Warehouse has doubled their team in the past year. Phillipe Gatien, Adam Bartlett, Eric Nadeau and Eric Vanderwal have joined our team to help operations.

HERCULES WAREHOUSE: 5 SAFETY TIPS FROM TERRY

1. KNOW THE RISKS

Be aware of hazardous risks associated with warehouse work. These include slips and fall (which are some of the most common injuries on any jobsite, even offices) but warehouses present even more issues. Racking accidents, musculoskeletal injuries from improper lifting methods and temperature fluctuations are all risk factors for hazards.

You can’t prevent accidents or expect warehouse personnel to avoid hazards if they aren’t aware of them. 

2. PREVENT FALLS, MAKE HOUSEKEEPING A PRIORITY

Like we mention above, slips and falls are some of the most common warehouse injuries, and can be particularly dangerous when lifting equipment is being used. In Ontario, nearly 20% of lost-time injury claims were due to falls. To prevent falls and trips, be sure to have guards installed in areas where there are large spaces between floors that personnel could fall through. Mop and clean up spills, slippery materials like sawdust, and be sure to store boxes properly – not on the warehouse floor where someone may trip over them.

Train and make personnel aware of any abnormalities that might cause them to trip, like cracks in the floor, uneven stairs or plugged-in cords; and also human error that easily contributes to falls, like tools or equipment placed on the floor for just a moment.   

3. KEEPING TRAINING CURRENT

Yes, maybe employees who have been hired years ago have been trained, but as new standards come out, personnel should be familiar with them. Be sure to give thorough training on any new technologies you bring in, like connective radios or tracking systems, hand signals & important communicative phrases, and make sure safety and equipment training is up-to-date – to do this, give personnel ‘refresher’ courses regularly and hold safety meetings with warehouse personnel. 

4. USE EQUIPMENT PROPERLY

Again, « Isn’t this common-sense? » you probably think. However, one of the top citations OSHA gives out each year are for equipment violations. Ever see this scene from ‘The Office’? Some people shouldn’t use the forklift.

Make sure personnel has the proper training and licenses to operate machinery like forklifts, aerial lift trucks and even fall protection. Safety harnesses can be used improperly, which can lead to accidents. For example, a Hercules SLR inspector was once called into a warehouse operation whose safety equipment was often breaking. When he entered the warehouse, he saw a worker swinging from side-to-side on various platforms with a safety harness and lanyard which were only supposed to be used vertically. This was improper use, which explained why their safety equipment was failing so frequently.

In 2018, three of OSHA’s most frequent citations in warehouses were for Fall Protection training & general requirements and industrial truck violations – invest in training for warehouse personnel, especially when fall protection is being used.

5. HAZARD COMMUNICATION 

Another citation OSHA often gives out is for hazard communication. Hazardous chemicals can cause corrosion, respiratory issues or become flammable, and should be labelled. Hazard communication includes proper labelling, education for employees about the risks involved and plans to control spills and proper disposal.

CM’s Tips: Crane & Hoisting Equipment in Hazardous Areas

cm hoisting equipment at hercules slr

COLUMBUS MCKINNON GUEST BLOG: How to Use Hoists & Cranes in Hazardous Areas

This guest blog is reprinted with permission from the experts at Columbus McKinnon. Their specialists give you an overview of safe practices to follow to operate crane and hoisting equipment in hazardous environments. 

CRANE & HOISTING EQUIPMENT IN HAZARDOUS AREAS: THE NEED FOR SPARK RESISTANCE 

Among many industries that range from upstream oil and gas, refineries to agriculture and wood working, many potentially flammable atmospheres exist. These areas can present unique challenges for material handling equipment and can pose a serious threat to materials, equipment and most importantly, personnel.

In Canada, hazardous areas are defined and managed by a few different regulatory bodies, including the Canada Labour Code, the Canadian Standards Association and the Canadian Centre for Occupational Health & Safety, to name a few. 

FACTORS

It’s generally understood that friction between certain materials can cause sparks sufficient enough to ignite flammable gas or dust. A cigarette lighter or an antique flintlock musket are common examples of this. Obviously the type and concentration/dilution of gases in an area is one element that affects potential ignition from a mechanically generated source, but other key factors could include:

  • The type materials making contact
  • The speed/pressure with which the materials come into contact
  • Corrosion on one or more of the contacting surfaces
  • Lubrication

To address this potential risk, Columbus McKinnon uses materials such as copper, bronze, and austenitic stainless steel, which are generally considered non-sparking. These are used for coatings, or as material substitutions for enhanced spark resistance. Not only are these materials spark resistant, but they can also protect against corrosion. Since surface corrosion can increase friction between mating components, corrosion prevention is also important when using material handling products in hazardous environments.

CM crane and hoisting in hazardous areas, Hercules SLR

Columbus McKinnon engineers a variety of specialty products with spark-resistant components and finishes, including:

  • Solid bronze hooks, bottom blocks and trolley wheels
  • Bronze plated components
  • Stainless steel load and hand chain
  • Multi-coat epoxy finishes
  • Zinc-aluminum corrosion-resistant finish

CRANE & HOISTING EQUIPMENT IN HAZARDOUS AREAS: THE NEED FOR CORROSION RESISTANCE

As we mentioned earlier, lifting equipment used in classified hazardous locations must be compliant with applicable standards. 

It’s important to make sure critical mechanical components are resistant to sparks – it’s equally important to make sure these parts are protected from corrosion. These parts include: 

  • Load blocks
  • Trolley wheels
  • Load brake
  • Lifting mediums
  • Chain
  • Wire rope

Many classified hazardous areas exist outdoors that expose lifting equipment to direct, and often harsh weather. These include offshore oil platforms, natural gas processing plants and refineries – to name a few. Specifically in offshore facilities, equipment may be exposed to splash zones, salt spray and the condensation of salt-laden air. In addition to harsh and corrosive weather conditions, sulfur, mineral acids and other corrosive agents are often present in the crude oil and natural gas that is being produced, processed and transported in these facilities, working to further corrode lifting equipment used in these environments.

CORROSION = $$$ cm hoisting equpment from hercules slr

The cost of corrosion can be tremendous, and can add up to billions of dollars each year in the oil and gas industries alone. In these industries, the cost to repair and replace corroded lifting equipment combined with unscheduled maintenance, downtime and lost production have a major impact on profitability. Corroded load blocks, hooks, chains and cables can result in catastrophic equipment failure. Not only can this cause costly damage to the equipment and the facility, but most importantly, can cause injury or be fatal to operators and other personnel in the facility. 

So – how do you protect lifting equipment from corrosion? It’s critical to use corrosion-resistant materials for load blocks, hooks, chains, cables and other components. Since surface corrosion can increase the friction between mating components, corrosion prevention is important to maintain mechanical spark resistance when using these products in a classified, hazardous environment.

Columbus McKinnon offers a variety of solutions for these challenges, in the form of a wide range lifting products with spark and corrosion resistant materials and coatings. They also offer application engineering assistance to help determine the right solution for your application. Choose from specially engineered products with:

  • Solid bronze hooks, bottom blocks and trolley wheels
  • Lightweight aluminum housings
  • Stainless steel load and hand chain
  • Multi-coat epoxy finishes
  • Zinc-aluminum corrosion-resistant finish

In addition to corrosion-resistant materials and finishes, we also suggest proper hoist lubrication to prevent sparking. These measures, combined with a robust inspection and preventative maintenance program that includes pre-lift inspections, play a critical role to make sure equipment is dependable and safe in these harsh environments. 

Regardless of where you do business, CM has hoisting equipment and cranes to keep your people, materials and equipment safe in hazardous areas. 

 

CRANE & HOISTING EQUIPMENT IN HAZARDOUS AREAS: SPACE CONSTRAINT CHALLENGES & SOLUTIONS

Earlier in this article, CM discussed the need for mechanical spark resistance and corrosion-resistant measures, especially in hazardous environments. This section outlines challenges faced working with space constraints, how they can be increased in hazardous environments and solutions to potential problems.

SPACE CONSTRAINT CHALLENGES

Another example of a constrained space. Photo courtesy of CM.

Classified hazardous areas frequently exist within confined spaces, especially in the mining and oil & gas industries. In mining, tunnels often have low overhead clearance in areas where coal or other flammable dust may be present. In the oil and gas industry, designers of offshore facilities typically look to minimize the overall size of the structure, which can lead to low headroom between deck levels and tight clearances for monorails and crane runways.

In all of these situations, there is a need for overhead lifting equipment that is compact in design, including low headroom and short side clearances, as well as a short “end approach” to maximize the deck coverage area served by the monorail hoist or crane.

This need for compact hoists, trolleys and cranes is often complicated by the possibility that flammable gases or dust may be present in the areas where the equipment is used. Therefore, explosion-proof and spark-resistant features may be needed, each posing their own challenges given the space constraints. For example, explosion-proof electric motors and control enclosures are typically larger and heavier than those for non-hazardous areas. Spark-resistant bronze load blocks and hooks tend to be larger than carbon or alloy steel hooks and blocks with the same safe working load. Also, the use of spark-resistant stainless steel load chain or wire rope often requires the equipment capacity to be de-rated due to lower tensile strength of stainless versus alloy steel. This de-rating can sometimes result in larger, heavier and more costly hoists and cranes.

SOLUTIONS 

As you can see, there are many factors to consider when specifying or purchasing lifting equipment for hazardous locations with space limitations. When dimensional constraints within facilities and working environments compete with the need to comply with hazardous area requirements, the safety of personnel, equipment and facilities themselves must always take precedence in our decision making.

Fortunately, there are a variety of hoisting equipment options available, featuring spark- and corrosion-resistant materials and explosion-proof components, that can be used in confined areas. Low-headroom hoists are offered in both wire rope and chain varieties, including manual, electric and pneumatic models.

Wire rope hoists can typically provide higher capacities and faster lifting speeds, while chain hoists can offer smaller overall dimensional envelopes to optimize end approach and clearance. Solid bronze and stainless steel components can provide lasting protection against sparking and corrosion, but, in some applications, copper or nickel plating can be substituted to provide lower headroom dimensions and reduce the need for de-rating of safe working loads.

CM has solutions to many of these problems. Products that work in many different restricted areas for this purpose are: 

  • Ultra-low headroom hoist models 
  • Low-profile hoists 
  • Wire rope hoists/crane rope

Confined Space Rescue & Retrieval: Guest Blog from 3M

3m confined space rescue from hercules slr

Incidents that prevent workers from self-rescue can occur in confined spaces due to ill-conceived attempts to rescue and retrieve others, but planning for a rescue can help prevent tragic results.  

Proper rescue and retrieval plans aren’t often created for confined spaces – over 100 deaths occur annually inside confined spaces in the United States according to the Bureau of Labor and Statistics1. In almost all of these incidents, investigations reveal no rescue plans were in place. Before entry or work begins, OSHA requires you have a defined and documented rescue and retrieval plan that’s specific to your confined space – whether a tunnel, storage tank, manhole, elevator shaft, reaction vessel, ductwork or even wastewater treatment facility.

But a detailed rescue and retrieval plan is only one critical step of preparation (one of the four elements 3M talks about here). Rescue and retrieval needs to be performed by a competent person, who’s completed proper training. They must also understand how to select, wear and use appropriate personal protective equipment (PPE) and other tools or equipment that will be needed.

HAVE A RESCUE PLAN IN PLACE BEFORE ANY ENTRY OCCURS

There are many aspects of a robust rescue plan, but at minimum the rescue plan should include:

  • The location of the confined space and the job being conducted inside;
  • Identify the rescuer, competent person to be on hand, emergency contact and methods to keep in contact with those in the confined space and anyone involved if a rescue becomes necessary;
  • Layout all pre-work tasks;
  • Catalog all the rescue equipment available for use and where they can be located – include a checklist for thorough inspection that evaluates if it’s in good working order;
  • List all the critical rescue factors, include any hazards present;
  • Record the response procedure, include how to:
    • notify the emergency contact
    • make a medical assessment of the person stuck inside
    • if possible, how to have the trapped employee perform a self-rescue, or other crucial steps if that’s not possible.

You can model your emergency response plan after the NFPA 350 best practice guide. Determine appropriate means for rescue before the start of any confined space entry activities. The procedures set up at your work or job site for emergency rescue for each specific confined space should to be suitable and sufficient.

The detailed rescue plan should be documented, reviewed and in place before anyone attempts to enter or begins work in a confined space. The rescue plan for each confined space should be reviewed by all involved in the entry each time the space is going to be entered, just like a hazard assessment should be conducted before entry into a confined space. These plans should be practiced as part of training so everyone knows what to do if a rescue/retrieval situation does arise.

No plan in place to enter a confined space? You should speak up, and not enter the confined space without a plan in place for how to react if a rescue and retrieval becomes necessary.

MAKE SURE YOU’RE PROPERLY TRAINED TO RESCUE

Before any access is granted to a confined space, you should evaluate the needs of a rescue team and what training is required for the team (or individual) to perform a rescue operation. Tailor training to specific roles required – you should include:

  • Confined space competent person who is responsible for the evaluation of confined spaces on the job site
  • Confined space supervisor who approves the work inside that’s being done
  • Confined space attendant and entrant for those who are responsible for the work inside
  • Confined space entry rescuer who may have to enter and assist in a rescue/retrieval

All confined space rescuers, per the requirements of OSHA general industry and construction regulations are required to receive annual refresher training. This must include utilizing similar spaces and techniques anticipated at the job site.

You’ll find, rescue training covers a wide range of information related to hazardous conditions and all types of rescue equipment. Rescuers will also require training to prepare for tasks involved with accessing confined spaces, such as descent control, secondary systems, patient packaging methods, dismantling techniques, proper storage of equipment, selection, and use of suitable anchors, as well as the common hazards that pertain to the system and components.

For rescues requiring entry:

  • All members of the team must be specially trained in confined space rescue work
  • The team must have at least one member certified in CPR and first aid
  • All members of the team must be trained in the techniques and equipment for specific confined spaces
  • The members who are going to assist with the rescue should be well-versed in the rescue plan for that confined space and review both the risk and hazard assessments that have been conducted for that specific space

According to current U.S. regulations and industry standards, an identified rescuer, whether in-house or an outside rescue service is used, must have the ability to respond to a permit space rescue request in a timely manner, considering the hazards identified.

TYPES OF RETRIEVAL AND RESCUE

There are different types of rescue/retrievals that can be conducted, depending on the situation you and your team are facing.

SELF-RESCUE

Self-rescue is exactly what it sounds like. This is when you can rescue yourself with your own means and you can use equipment that is suited for self-rescue that will allow you to climb out of the space safely. Self-rescue requires the entrant to stop what they are doing and safely exit the space as quickly as possible.

Self-rescue should be implemented whenever an entrant or attendant determines there is a problem within the space. This may include a potentially hazardous change in atmospheric conditions within the space or when signs or symptoms of an exposure are noted. Self-rescue may also occur if the entrant realizes that PPE is faulty, communication with the attendant is severed, or some other hazard presents itself that may put the entrant in danger.

NON-ENTRY RESCUE

If self-rescue is not an option, the next consideration should be if a non-entry rescue can be carried out. Non-entry rescue occurs when a worker outside the space does not have to enter to help a worker exit a confined space safely. This type of rescue often requires an attendant or non-entry rescue team. A non-entry retrieval option is required at all times unless the retrieval equipment would increase the risk to the worker or not contribute to the rescue.

The person or people helping the worker out of the confined space will often require the use of a retrieval system comprised of the following components:

  1. Anchor systems such as a davit, pole hoist or tripod
  2. Body harness, worn by the entrant
  3. Connection devices such as a winch or retrieval SRL

This type of rescue is only effective in simple vertical or horizontal spaces. The opening must be able to accommodate the anchor system, and the surface around the opening must support the weight of it in addition to the attached entrant. If the entrant is injured or cannot perform a self-rescue, the attendant can remove the entrant using the retrieval system. This is where a retrieval system with a mechanical advantage becomes very helpful.

If neither self-rescue or non-entry rescue is possible, an entry rescue will be required. If you have a properly trained rescue and retrieval team, they will need to be called upon to help perform getting the entrants out.

ENTRY RESCUE

An entry rescue is required when someone cannot get out on their own and requires not just a team on the outside to assist, but someone who will enter the space to assist any entrants who cannot exit the space on their own. These teams can be comprised of company personnel, including externally hired services or a local emergency response team. Because there needs to be a prompt response in these situations, OSHA specifically addresses the requirements of the entrant’s employer to fully evaluate the capabilities of these rescue teams.

POST-RESCUE REVIEW

Once a rescue is complete, it is important to review how the rescue went and what can be learned from the experience. Do changes need to be made to the rescue plan if the confined space is going to be accessed in the future? Does your PPE need to be checked and should any of it be decommissioned and different or should new PPE ordered?

PPE AND OTHER EQUIPMENT

As part of a rescue plan and the hazard assessment conducted for each confined space entry, make sure you have identified what PPE and other equipment, such as air monitoring/gas detection instruments, are needed. Also, be sure everything is available in stock on the premises, the location is known, the equipment is clean and is in good working order before commencing any access work.

When it comes to considering the equipment for a rescue start with understanding the ABC’s of confined space:

  • Anchorage systems such as davits, pole hoists, tripods

  • Body support, which means full body harnesses, and in some cases, boatswain (bosun) chairs

  • Connecting devices such as self-retracting lifelines and retrievals

  • Detection for air monitoring of gases, vapors, particulates, fumes and other hazardous substances

  • Education courses that help teach proper techniques

  • Full body coverage for employees who should be protected from head to toe based on hazards identified in the risk assessment, including hard hats, safety glasses, hearing protection, advanced communication devices, respiratory protection, clothing that protects the body against chemicals, fires and other hazards such as coveralls, as well as gloves and safety shoes that protect the hands and feet

ARE YOU READY IF A RESCUE OR RETRIEVAL BECOMES NECESSARY?

Proactively identifying a proper rescue plan, seeking out appropriate training and identifying the right equipment long before any rescue is ever attempted is crucial. You must be prepared so if you’re faced with saving someone who’s stuck, has collapsed, or has ceased to respond from inside a confined space, you are ready for the situation.

Incidents that prevent workers from self-rescue can occur in confined spaces due to ill-conceived attempts to rescue and retrieve others, but planning for a rescue can help prevent tragic results.                              

Proper rescue and retrieval plans aren’t often created for confined spaces – over 100 deaths occur annually inside confined spaces in the United States according to the Bureau of Labor and Statistics1. In almost all of these incidents, investigations reveal no rescue plans were in place. Before entry or work begins, OSHA requires you have a defined and documented rescue and retrieval plan that’s specific to your confined space – whether a tunnel, storage tank, manhole, elevator shaft, reaction vessel, ductwork or even wastewater treatment facility.

But a detailed rescue and retrieval plan is only one critical step of preparation (one of the four elements 3M talks about here). Rescue and retrieval needs to be performed by a competent person, who’s completed proper training. They must also understand how to select, wear and use appropriate personal protective equipment (PPE) and other tools or equipment that will be needed.

HAVE A RESCUE PLAN IN PLACE BEFORE ANY ENTRY OCCURS

There are many aspects of a robust rescue plan, but at minimum the rescue plan should include:

  • The location of the confined space and the job being conducted inside;             
  • Identify the rescuer, competent person to be on hand, emergency contact and methods to keep in contact with those in the confined space and anyone involved if a rescue becomes necessary;
  • Layout all pre-work tasks;
  • Catalog all the rescue equipment available for use and where they can be located – include a checklist for thorough inspection that evaluates if it’s in good working order;
  • List all the critical rescue factors, include any hazards present;
  • Record the response procedure, include how to:
    • notify the emergency contact
    • make a medical assessment of the person stuck inside
    • if possible, how to have the trapped employee perform a self-rescue, or other crucial steps if that’s not possible.                          

You can model your emergency response plan after the NFPA 350 best practice guide. Determine appropriate means for rescue before the start of any confined space entry activities. The procedures set up at your work or job site for emergency rescue for each specific confined space should to be suitable and sufficient.

The detailed rescue plan should be documented, reviewed and in place before anyone attempts to enter or begins work in a confined space. The rescue plan for each confined space should be reviewed by all involved in the entry each time the space is going to be entered, just like a hazard assessment should be conducted before entry into a confined space. These plans should be practiced as part of training so everyone knows what to do if a rescue/retrieval situation does arise.

No plan in place to enter a confined space? You should speak up, and not enter the confined space without a plan in place for how to react if a rescue and retrieval becomes necessary.

MAKE SURE YOU’RE PROPERLY TRAINED TO RESCUE

Before any access is granted to a confined space, you should evaluate the needs of a rescue team and what training is required for the team (or individual) to perform a rescue operation. Tailor training to specific roles required – you should include:

  • Confined space competent person who is responsible for the evaluation of confined spaces on the job site
  • Confined space supervisor who approves the work inside that’s being done
  • Confined space attendant and entrant for those who are responsible for the work inside
  • Confined space entry rescuer who may have to enter and assist in a rescue/retrieval

All confined space rescuers, per the requirements of OSHA general industry and construction regulations are required to receive annual refresher training. This must include utilizing similar spaces and techniques anticipated at the job site.

You’ll find, rescue training covers a wide range of information related to hazardous conditions and all types of rescue equipment. Rescuers will also require training to prepare for tasks involved with accessing confined spaces, such as descent control, secondary systems, patient packaging methods, dismantling techniques, proper storage of equipment, selection, and use of suitable anchors, as well as the common hazards that pertain to the system and components.

For rescues requiring entry:

  • All members of the team must be specially trained in confined space rescue work
  • The team must have at least one member certified in CPR and first aid
  • All members of the team must be trained in the techniques and equipment for specific confined spaces

NEWS: planning is essential in confined spaces

confined space training by hercules slr

Confined spaces—we’ve discussed the dangers of working in confined spaces, confined space training and the importance of choosing the right fall protection equipment on our blog before.

On Tuesday, November 20 in Uruguay, two shoreshide dock workers died and two were hospitalized after being exposed to a fumigant. Currently, the Uruguayan Navy is unsure which chemical caused the fatalities and injuries—however, it’s believed to be caused by the treatment phosphine, a fumigation gas used to control pests in agricultural and wood product cargoes. Phosphine is denser than air and can settle into low-lying pockets, reports the Maritime Executive.

Investigators say two dock workers from an independent company entered a freighter from Panama when they lost consciousness and collapsed—a crewmember say the dock workers struggle and entered the space wearing a face mask, but removed it while trying to rescue the workers. He also collapsed and is in the hospital in an induced coma. A third member of the company is also in hospital with injuries, reports the Maritime Executive.

According to the president of the Uruguayan Transport Union, Cesar Bernal, dock workers were not aware half of the ship’s cargo was treated with a fumigant. They followed their normal procedure for entering the space in the freighter, and were affected immediately by the fumes.

The industrial trades will benefit from improved communication regarding hazardous fumes, and more effective training regarding fall arrest and confined space entry and exit training. Something like an SRL (self-retracting lifeline) may help in a situation like this, where a worker can easily lift himself from a dangerous space. The National Institute for Occupational Health & Safety reports that 60% of confined space fatalities in coastal accidents are rescuers.

The Canadian Centre for Occupational Health & Safety (CCOHS) recommends that employers develop a confined space hazard assessment and control program—especially since most workers in the industrial trades will work in a confined space at least once during their career. This program should be specific to the work being done, and employers may need to implement more than one program.

CCOHS recommends your plan include the following:

  • Description of roles and responsibilities of each person or party (e.g., employer, supervisor, workers, attendants, and emergency response team);
  • Advice on how to identify confined spaces;
  • Identification and assessment of all potential hazards that may exist at the beginning of the work as well as those that may develop because of the work activities;
  • A plan to eliminate or control all identified hazards;
  • Written work procedures;
  • Confined Space training program for all the workers that will enter confined spaces;
  • An entry permit system for each entry into a confined space;
  • Development of an emergency plan complete with training and equipment in case an unforeseen situation occurs;
  • An emergency response system;
  • Reporting and investigating incidents related to work in confined spaces;
  • Record and documentation control;
  • Program review whenever there is a change in circumstances or at least annually, to identify program weaknesses and make any necessary changes to the program.

Confined Space Training

Unfortunately, many injuries and fatalities are easy to prevent if the proper safety measures and plans are put into place. Give you and your employees the knowledge and skills they need to be safe in confined spaces. Browse information on our Confined Space Entry & Attendant, and more safety courses here.

Confined Spaces: Hercules’ Safety Tips

confined spaces safety training from hercules slr

What is a Confined Space?

Confined spaces are present in nearly every industrial trade, and most workers will encounter at least one confined space during their career.

The OSHA states that nearly 90 deaths occur per year, across a range of industries involving confined spaces. Almost 2/3 of these fatalities are caused during an attempt to rescue someone in a confined space—having an efficient, established retrieval plan in place is essential to preventing death and injury.

A confined space is defined as a entirely or considerably enclosed space, where dangerous conditions are present due to lack of oxygen or hazardous substances.

What else constitutes a confined space? A space which is large enough for a person to enter or exit, has limited or restricted exits and isn’t designed for extended human occupancy. A confined space may have more than one opening, however—if a worker must climb through various obstacles to access the opening, this may be considered a confined space as well.

Confined spaces also may temporarily appear on a work site through construction, fabrication or modification. Tunnels, manholes and silos are all examples of confined spaces.

What is a Permit-Required Confined Space?

Not only are permit-required confined spaces difficult to enter, they present serious hazards like inadequate ventilation or noxious air. These include:

  • Hazardous atmosphere or potential for one;
  • Material, like grain that could engulf an individual;
  • Walls converging inwards, or floors sloping downward and tapering into a smaller area that could trap or asphyxiate an individual;
  • Any other recognized hazards, like unguarded machinery, heat stress, or a fall hazard.

These confined spaces present a great threat as they’re more likely to cause fatalities—a quick and simple exit, or rescue must be possible for workers in confined spaces. The safest rescue strategies involve no additional employees entering the space—retrieval equipment should be used unless unsafe to do so.

Confined Space Training

 

What Makes Confined Spaces Dangerous, Anyway?

Not only are confined spaces difficult to enter, exit and navigate, they present a series of other dangerous threats many workers may overlook. Dangers commonly present themselves when welding, painting, flame cutting or using chemicals in a confined space. Other risks include:

  • Lack of oxygen;
  • Poisonous gas, fume or vapour;
  • Liquids and solids suddenly filling the confined space, gas releasing in the space when disturbed;
  • Fire and explosions;
  • Residues left behind that give off gas, fume or vapour;
  • Hot working conditions;
  • Falling objects;
  • Moving parts of equipment or machinery;
  • Electrical shock resulting from defective extension cords, welding cables, etc.;
  • Poor visibility;
  • Materials travelling through piping like gases, hot substances or water.

Fall-Prevention Training is Essential for Safety in Confined Spaces confined-spaces-fall-prevention

As previously mentioned, having an established and efficient rescue plan for workers’ in confined spaces is essential. Fall protection, or prevention training is another not only important, but essential step to ensure safety.

There are five main steps to consider when safeguarding a confined space:

  1. Guard the entrance: A guardrail, barrier or another temporary cover must be in place to prevent entry (i.e. an accidental fall) into the space.
  2. Wear fall-protection gear: All workers, even those not working in the space should have proper fall-protection gear. Dangerous factors may affect nearby workers, like fumes. Equipment like Restraint Lanyards that stop an appropriate distance from the confined space should be used by other workers.
  3. Make sure vertical access is safe: Typically, a ladder or a davit arm with a winching mechanism is used to safely access the confined space.
  4. Use fall-arrest equipment: The main components of fall protection for a confined space are an anchorage, body support and a connector. Workers should have a backup for their primary entry and exit source. If using a ladder for example, the worker should also have a retractable lifeline and a winching mechanism, or may have a safety harness with a retractable winching mechanism to lower, and raise workers into the confined space. Equipment will depend on a vertical or horizontal entry.
  5. Training: If a workers is unfamiliar with fall-protection equipment, the term itself or has no recorded instances of fall-protection or prevention training, the employee must be trained to inspect and use fall-protection equipment and know general information regarding fall-protection.
