Suspension Trauma: 3 Must-Know Myths

suspension trauma myths to know

Suspension trauma has a few different names—Harness hang, harness-induced pathology and orthostatic intolerance (the medical term). Consequences can be fatal, and it’s important to be aware of symptoms and ways to prevent its onset.

Suspension trauma has its fair share of misconceptions—One of the biggest is that it’s a myth. 

In this article, we discuss three myths that surround suspension trauma you must know. 

MYTH #1: SUSPENSION TRAUMA ISN’T REAL

It is! Suspension trauma happens when a worker’s movement is vertically suspended, restricted and upright for an extended period of time and lose consciousness.

But why does this happen? Blood pools in the legs and makes them swell, while blood pressure drops. Typically, when orthostatic intolerance sets in the victim faints so blood will re-circulate through the body—A worker in restrictive fall arresting equipment can’t do this. 

It can be minor, too—A common example is people who are still for long periods of time and faint, or feel dizzy when they get up. 

Now, imagine you’ve arrested a fall, don’t have a rescue plan and first responders are still on the way. 5 minutes, 10 minutes, and now 25 minutes pass. You know that suspension trauma can set in after just 30 minutes. Time is ticking. You’re covered in sweat, you feel dizzy and terribly nauseous.

Finally, you’re cut down and pass out, unconscious. You’re in the hospital—There’s paperwork, lost-time and incident investigations to happen. Who knew a little slip could cause so much trouble?

Yes, you’re alive, but next time, you’ll definitely have a rescue plan. And suspension trauma is real.

MYTH #2: SAFETY HARNESSES MAKE SUSPENSION TRAUMA EXTINCT

Suspension trauma is still a reality. Yes, education, training and equipment reduce injuries and fatalities in industrial workplaces, but prevention is still a priority. Look at it this way—Vaccines exist for illness like the measles, but people still contract it when they don’t use preventative measures. 

Individual factors increase a worker’s risk to develop the trauma, and its effects are not easy to predict person-to-person. 

These factors include: 

  • Individual’s ability to manage anxiety/stress
  • Harness selection & fit
  • Poor training
  • Previous injury or illness 

This is why training is vital. It’s important to teach employees not only what happens when you use the wrong PPE, but psychological coping mechanisms to help a worker deal with a potential fall. Proper training will also emphasize the importance to continuously move your legs in specific ways to maintain circulation—It’s important The right safety harness and leg straps will allow the worker to move 

MYTH #3:  WHEN THE HARNESS IS OFF, IT’S OVER 

Okay, so when I take the safety harness off I’m fine, right? Wrong.  

Workers in vertical positions must receive medical attention immediately after release. In past suspension trauma cases, victims have died after the harness comes off—This is known as ‘rescue death’.

Some doctors think it’s caused when blood tries to circulate through the body at its normal pace, and can’t. Did you know leg muscles are one of your body’s auxiliary pumps? When legs hang, motionless and upright, it pinches the arteries and blood can’t flow to crucial parts of the body, like the heart and brain. 

  • Leg circulation
  • Heart circulation
  • Brain circulation 

Fortunately, like we mention above, industrial environments benefit with the right personal protective equipment (PPE) and training to prevent suspension trauma. Recorded injuries from suspension trauma are somewhat rare—But training and proper PPE are key to this.

A body harness that doesn’t fit properly, is fit with the wrong accessories or is uncomfortable, does more harm than good. Remember—Suspension trauma does exist, the right safety harness help prevent it and negative effects of suspension trauma can linger after the harness is off. It’s important to train yourself and workers (even those who may not be working at heights) of the risk and procedures to take before, during and after a fall.

Fall Protection Training: don’t get left behind

fall-protection-training-dont-get-left-behind

Fall Protection Training: don’t get left behind

Fall protection and training for is easy to overlook when there’s a job to be done—who has time to strap on a safety harness? You do.

Worker at height with SRL

At Hercules SLR, safety is a priority in all areas of our company. We spoke with some experts around the office about fall protection safety training – think safety harnesses, self-retracting lifelines and anchorage lines. They all agree that equipment alone is not enough – workers must be trained to use it properly. Training should be engaging, hands-on and fun to have workers actually use this equipment.

We want workers and employers alike to be aware of fall protection’s importance and the difference the right training makes. Read on to discover tips from our safety experts that will make you and your employees want to use their fall protection gear.

Fall Protection Training: are you credible?

Credibility is a large aspect of effective training and communication—do you sit behind a desk all day? Do you climb a 12-foot ladder daily? Regardless of the words you say, who you are will effect the message you’re trying to deliver.

“I had a professor in University who was from Poland, and her Family had escaped from the Nazi’s during their reign – her experience gave her credibility when she taught us European history, and even as students it made us pay attention,” remarks Business Development Manager, Consultant and Safety Trainer & Inspector Lou Gould on the difference credibility makes.

Fall Protection Training: know your audience

It’s important to know that while there’s overlap, there are differences among the industrial trades—it’s important to know the differences and not generalize when explaining the importance of fall protection gear.

Says Gould “Once, I was at a meeting where the topic was roof workers safety. The guy who was giving the presentation was an electrician, but was only speaking from his experience. I noticed right away a lot of guys in the room ‘check out’ so to speak, since he wasn’t addressing their specific problems or issues. It’s important to know your audience, especially when you’re trying to get an important point across.”

Experience is a great teacher. He continues, “The classroom is a sharing experience with everyone you’re with. Personally, I am a story-teller, and I’ve found this makes a great environment to learn. Whether it’s a situation you’ve been in or just witnessed, being able to say ‘I’ve seen someone use this before and protect them’ tends to stick in everyone’s head better than reading straight from a text.”

Use industry-specific examples to show how fall protection gear will improve and enhance their daily work. For example, talking to roofers? Mention how slippery roofs become during inclement weather – something your audience relates to.

Fall Protection Training: risk management vs. risk communication

When you reflect on an incident, there are typically thousands of tiny moments that led to that one disaster. All are entirely preventable – nothing is random. However, explaining how a fallen wrench can lead to a fatality isn’t something all trainers can do.

In the safety industry, we talk about risk management all the time, but we never talk about risk communication. Risk communication is the ability to explain the process of an injury, how they can escalate and what is being done to mitigate or in worst-case scenarios, investigate and provide conclusions. In the safety industry, many trainers have extensive knowledge but are don’t deliver it in a way that makes their audience pays attention.

ppe-fall-protection-training-safety-harness
Hercules SLR employee at height with their safety harness

It’s not enough to say “an 8-lb wrench dropped can cause fatal injuries” – which is an approach many trainers take. Hercules SLR trainers know that reading out facts is not enough. It’s much more effective to say “an 8-lb wrench dropped from 200 feet above has 2,833 pounds of force per square inch – which is equal to a Clydesdale horse hitting a 1 square inch area.”

It’s important to explain causation when you emphasize the need for proper PPE equipment and fall protection training. Many workers have the perception that fall protection PPE and training is only essential for “big accidents” – think falls from height or worksite explosions. But the right training emphasizes PPE’s role in daily work.

Causation vs. Big Accidents

Help workers visualize common accidents that occur on worksites and the role causation plays in daily workplace safety. For example, the nursing profession has many different hazards to mitigate. A few factors that contribute are, long shifts, high-stress nature of the job, aggression in the workplace, high emotional environment, poor housekeeping and lifting at awkward angles. The stressors through the day can contribute to injury and low-productivity. Financially, employers and owners can expect to pay much more to repair or replace misused equipment, rather than taking measures to maintain it in the first place.

The proper equipment and training will reduce discomfort caused by misusing PPE & fall protection gear, while reducing worksite injury and accident and improving productivity.

Fall Protection Training: most importantly, make it fun

We hate to break it to you—but if you’re boring no one will listen to you.

Many Hercules SLR students that enroll are actually already certified riggers. Often, they’ll start to work on-site and realize they’re making too many errors, or they enroll in other rigging courses and realize their skill isn’t on par with their peers.

Going forward, a big trend is the transition to a blended-training model. Blended training involves both a practical and classroom/online component, with a focus on engaging, hands-on activities, demonstrations.

Our Aerial Work Platform Training course is a great example of this. We spend 3-4 hours in the classroom and cover theory, and then we operate machines all afternoon. Right now, industry trend is to complete an online module that before the practical, then students come to the facility and complete their final practical test. This gives our trainers more hands-on training with the students and equipment than is available with more traditional training models.

Hercules SLR Training

Hercules SLR offers high-quality safety training and certification courses. We’ll customize courses to fit your workplace’s specific needs, and we’ll provide training on-site or at a Hercules SLR facility.

We don’t just offer safety and fall protection training – we’ll inspect, repair and certify your equipment too. Have your inspection done with Hercules SLR and gain access to our exclusive asset management tool, CertTracker. CertTracker maintains inspection records, gives advance notice of inspection due dates and schedules service times – Consider it your tool for great safety compliance.

Confined Spaces: Choose the Best Fall Protection Equipment

Confined-space-header-2
Proper Fall Protection Equipment: stay safe in confined spaces

We’ve given you tips for remaining safe in confined spaces and preventing injury—but how do you choose the best fall protection equipment to keep yourself and others safe? Read on and discover Hercules SLR’s tips for choosing the safest fall protection equipment for work in confined spaces.

Three Essential Components to Confined Space Fall Protection Equipment

When choosing the best fall protection equipment, you typically need an anchorage, body support and a connector. If entering a confined space vertically without a fixed ladder, you must have an anchor point that supports the required forces.

If entering horizontally, but with a vertical position, or you must retrieve someone or something (for example, on the side of a tank) you must have a side-entry system. This attaches to the access point with a bolt or clamp, and provides anchorage and a base for your winching mechanism.

When undertaking task-specific work, like entering a manhole, for example, tripods are the best option. They are easy to transport between locations, however, tripods only accommodate specific sized openings. If tripods aren’t enough, or more versatility is needed a davit arm, or post is another option to consider.

Davits are great for use at various types of worksites. Davits are a versatile choice as they can be fixed or portable. Some feature adjustable bases capable of hoisting workers over large openings, while others have fixed a “v” shaped adjacent to the opening.

confined space training

Support Yourself

Supporting body weight is an essential function of fall protection equipment—it’s important to consider comfort and durability when choosing appropriate fall protection equipment.

Have an employee working in a confined space for an extended period of time, or in various spots throuconfined-space-fall-protection-equipment-safety-harnessghout the day? Consider investing in a high-quality body harness with built-in shoulder, back and leg padding with soft edging for maximum comfort.

Need durability above all? Consider a harness with a protective coating specifically designed to be easily cleaned and repel dirt, grease and grime.

Need to access a confined space infrequently? Consider a basic harness, an economical option for work in confined spaces during a short period of time.

Easy Retrieval is Key

As we mentioned in our previous article, easy retrieval from confined spaces is key. For work in confined spaces (particularly for an extended period of time) consider a specialty harness with D-rings on each shoulder strap. A Y-Lanyard connects the two D-rings to a winch line, which allows workers to be raised and lowered vertically.

Your winch, or winching mechanism will include a steel or synthetic line and will be your connector. Your line will have a crank, and will connect to a tripod or davit system in order to lower and raise the employee. Security is a major benefit of this fall protection equipment—it includes a braking system, so if the winch operator release the winch, the worker being raised and/or lowered won’t fall.

For ease of use and frequent raising and lowering, a power drive is an optional feature to consider in your winch—it still has manual capabilities, and can be used automatically as well.

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.
