Risk Management: safety is every riggers’ business

Risk Management: what is it?

Risk management is the systematic process of assessing risk and acting in such a manner, or implementing policies and procedures in order to avoid or minimize loss associated with such risk. Essentially, risk management is a set of actions that reduces the risk of a problem, a failure, or an accident. The ISO 31000 defines risk management as “the effect of uncertainty on objectives”.

For the most part, risk management methods consist of the following methods:

  • Identify and characterize threats
  • Assess the vulnerability of critical assets to specific threats
  • Determine the risk (i.e. the expected likelihood and consequences of specific types of attacks on specific assets)
  • Identify ways to reduce those risks
  • Prioritize risk reduction measures based on strategy

Risk Management: know the definitions

Hazard: something with the likelihood to cause harm

Harm: physical injury or damage to health.

Risk: likelihood the hazard is realized – it happens

Severity: likelihood hazard or risk will occur, and the number of people affected and extent of consequences

Control Measures: the arrangements made to reduce risk

 

Risk Matrix

The purpose of the risk matrix is to determine the risk category. Once you have identified the project risks, review each risk in turn and assess both the likelihood of the risk happening and the severity of the impact on the project if the process doesn’t go as planned.

Risk Management: FLRA is more than just a funny word

Field Level Risk Assessment (FLRA) is a process used to assess the related hazards and their risks for a specific task or job.

A FLRA:
  • Helps reduce injury and to process loss
  • Is an industry standard
  • Is a requirement of most industrial establishment’s safety program
  • Is a requirement on most work sites

A FLRA should be completed:

  • At the start of each shift
  • Before re-starting work which has been stopped for a period of time
  • When site or work conditions change during a job
  • Before starting a new task or job for which there is no safe work procedure
  • Always check for specific requirements with onsite contact or employer
Who Can Conduct a FLRA?
  • Anyone can conduct a FLRA
  • All members of the work team need to participate
  • Sometimes other personnel on the work side need to be included
  • Sometimes a specialist or person familiar with the job and site needs to be involved

Risk Management:  your basic rigging plan

Follow this basic rigging plan to manage risk and avoid potential hazards. When you plan each lift, ask yourself the following questions:

  • Has a competent rigger been assigned?
  • Has a risk assessment been conducted with all team members?
  • What is the communication plan?
  • Has the rigging been inspected? (Pre-lift and annually?)
  • Is the rigging fit for the load type and purpose? (I.E. WLL, material, size, etc.) 
  • What is the weight of the load?
  • Where is the load’s center of gravity?
  • What is the sling angle?
  • Will there be any side or angular loading?
  • Are wear pads required against corners, edges, protrusions or abrasive surfaces?
  • Have the applicable hitches been selected for load control and stability?
  • Will personnel be in the way of the load or lifting equipment?
  • Is there any possibility of snagging? (Vertical, horizontal, travel path)?
  • Are there environmental concerns? (I.E. wind, temperature, visibility, power lines)
  • Is a tag line required to control the load?

Risk Management: complete a pre-use check

Pre-use safety checks are required before a rigger uses any lifting equipment or accessories – follow the manufacturer instructions and applicable ASME standards.

This includes a basic physical check of the equipment, which can significantly reduce the risk of health and safety issues that may arise on site during everyday operations.

ASME Standards

ASME Standards state: ASME B30.9 requires that sling users shall be trained in the selection, inspection, cautions to personnel, effects of environment, and rigging practices. Sling identification is required on all types of slings.

ASME B30.26 requires that rigging hardware users shall be trained in the selection, inspection, cautions to personnel, effects of environment, and rigging practices. All rigging hardware to be identified by manufacturer with name or trademark of manufacturer.

Lifting and Rigging Equipment: lifting with eye bolts

Lifting and Rigging Equipment: select the right eye bolt

There’s a lot of hardware to consider when researching lifting and rigging equipment. Links, hooks, swivels—today we’re talking eye bolts. Eye bolts are used to attach a securing eye to a structure, so ropes or slings can be pulled through.

Keep reading to discover how to select and use the right type of bolt, their dimensions and Working Load Limits.

Eye bolts are marked with thread size, not with their rated capacities. Make sure you select the correct eye bolt based on type and capacity for the lift you are conducting.

  • Use plain or regular eye bolts (non-shoulder) or ring bolts for vertical loading only. Angle loading on non-shoulder bolts will bend or break them.
  • Use shoulder eye bolts for vertical or angle loading. Be aware that lifting eye bolts at an angle reduces the safe load.
  • Follow the manufacturer’s recommended method for angle loading.

Lifting and Rigging Equipment: using eye bolts safely

  • Orient the eye bolt in line with the slings. If the load is applied sideways, the eye bolt may bend.
  • Pack washers between the shoulder and the load surface to ensure that the eye bolt firmly contacts the surface. Ensure that the nut is properly torqued.
  • Engage at least 90% of threads in a receiving hole when using shims or washers.
  • Attach only one sling leg to each eye bolt.

Direction of pull

 

  • Inspect and clean the eye bolt threads and the hole.
  • Screw the eye bolt on all the way down and properly seat.
  • Ensure the tapped hole for a screw eye bolt (body bolts) has a minimum depth of 1 1/2 times the bolt diameter.
  • Install the shoulder at right angles to the axis of the hole. The shoulder should be in full contact with the surface of the object being lifted.
  • Use a spreader bar with regular (non-shoulder) eye bolts to keep the lift angle at 90° to the horizontal.
    • Use eye bolts at a horizontal angle greater than 45°. Sling strength at 45° is 71% of vertical sling capacity. Eye bolt strength at 45° horizontal angle drops down to 30% of vertical lifting capacity.
    • Use a swivel hoist ring for angled lifts. The swivel hoist ring will adjust to any sling angle by rotating around the bolt and the hoisting eye pivots 180°.

 

Lifting and Rigging Equipment: eye bolt techniques to avoid

improper-eye-bolt-use-lifting-equipment
Don’t run your sling through an eye bolt!
  • Do not run a sling through a pair of eye bolts: this reduces the effective angle of lift and puts more strain on the rigging.
  • Do not force the slings through eye bolts. This force may alter the load and the angle of loading.
  • Do not use eye bolts that have been ground, machined or stamped.
  • Do not use bars, grips or wrenches to tighten eye bolts.
  • Do not paint an eye bolt. The paint could cover up flaws.
  • Do not force hooks or other fittings into the eye; they must fit freely.
  • Do not shock load eye bolts.
  • Do not use a single eye bolt to lift a load that is free to rotate.
  • Do not use eye bolts that have worn threads or other flaws.
  • Do not insert the point of a hook in an eye bolt. Use a shackle.
  • Do not use non-shouldered bolts to lift horizontally—non-shouldered bolts should only be used to lift vertically.

  • Ultimate Load is 5 times the WLL. Maximum proof-load is 2 times the WLL.
Definitions

* Ultimate Load: The load at which the item being tested fails or no longer supports the load.

** Working Load Limit: The maximum combined static and dynamic load in pounds or tonnes should be applied to the product in service, even when the product is new, and when the product is uniformly applied in direct tension to the product.

*** Maximum Proof-Load: The maximum tensile force that can be applied to a bolt without deformation. This is usually between 85-95% of the yield strength.
