Keep out from under a raised load. Take notice of the
recommendation from the National Safety Council Accident
Prevention manual concerning all lifting operations:
All employees working with cranes or hoists or assisting
in hooking or arranging a load should be instructed to
keep out from under the load. From a safety standpoint, one
factor is paramount: Conduct all lifting operations in such a
manner, that if there were an equipment failure, no personnel
would be injured. This means keep out from under a
raised load and keep out of the line of force of any load.
Inspect products regularly for visible damage, cracks,
wear, elongation, rust, etc. Protect all products from corrosion.
No product can keep operating at its rated capacity
indefinitely. Periodic inspections help determine when to
replace a product and reduce rigging hazards. Keep
inspection records to help pinpoint problems and to
ensure periodic inspection intervals.
Frequency of inspection will depend on environmental conditions,
application, storage of product prior to use, frequency
of use, whether or not life, limb, or valuable property are at
risk, etc. When in doubt, inspect products prior to each use.
Carefully check each item for wear, deformation, cracks, or
elongation - a sure sign of imminent failure. Immediately
withdraw such items from service. Rust damage is another
potential hazard. When in doubt about the extent of corrosion
or other damage, withdraw the items from service.
Destroy, rather than discard, items that have been judged
defective. They might be used by someone not aware of the
hazard of the defect.
Remember that any product will break if abused, misused
or overused. Therefore:
Working Load Limits
- Never exceed the working load limit.
- Match components properly.
- Keep out from under a raised load.
- Avoid shock loads.
- Inspect products regularly.
Never exceed the working load limit (WLL), safe working
load (SWL), or rated capacity. The working load limit is
the maximum load which should never be applied to the
product, even when the product is new and when the load is
uniformly applied - straight line pull only. Avoid side loading.
All catalog ratings are based upon usual environmental
conditions, and consideration must be given to unusual
conditions such as high or low temperatures, chemical
solutions or vapors, prolonged immersion in salt water, etc..
Such conditions or high-risk applications may necessitate
reducing the working load capacity. Working load limit will
not apply if product has been welded or otherwise modified.
Matching of Components
Components must match. Make certain that components
such as hooks, links, shackles, etc., used with wire rope (or
chain or cordage), are of suitable material and strength to
provide adequate safety protection. Attachments must be
properly installed and must have a work load limit at least
equal to the products with which they are used. Remember
that any chain is only as strong as its weakest link.
Avoid impacting, jerking, or swinging of load - working load
limit will not apply. A shock load is generally significantly
greater than the static load. Avoid shock loads.
