Date Issued: March 22, 2012 Date Revised:

Hoists are used for lifting and moving material. Like any other piece of equipment, there are a number of safety hazards associated with their use. However, these hazards can be mitigated by using basic hoisting safety practices and by following proper procedures.

Recommended Preventive Action


  • Read the hoist manufacturer’s operating manual and maintenance instructions.
  • Ensure all hoist operators and signallers are trained and familiar with the operating controls, procedures and warnings.
  • Inspect the hoisting apparatus before use and record the results in a logbook.
  • Check for damage, wear and proper operation of all functions. Replace damaged or worn parts.
  • Ensure proper equipment is used during lifts.
  • Ensure a hoist is not subjected to loads exceeding its safe working load.
  • Ensure the safe working load is legibly posted on the hoisting apparatus.
  • Never position any part of your body under a suspended load.
