Importance of Lockout/Tagout

Lockout/Tagout is a process to control energy hazards for preventing accidental start-up or release of stored energy during set-up, maintenance and servicing of equipment. OSHA outlines this safety method in standard 29 CFR 1910.147 (“Control of Hazardous Energy”). Lockout/Tagout is a widely accepted practice for companies in the United States.   OSHA advises US companies, “Workers servicing or maintaining machines or equipment may be seriously injured or killed if hazardous energy is not properly controlled. Injuries resulting from the failure to control hazardous energy during maintenance activities can be serious or fatal! Injuries may include electrocution, burns, crushing, cutting, lacerating, amputating, or fracturing body parts, and others….Craft workers, electricians, machine operators, and laborers are among the 3 million workers who service equipment routinely and face the greatest risk of injury. Workers injured on the job from exposure to hazardous energy lose an average of 24 workdays for recuperation.” Here are 3 examples of accidents due to a lack of Lockout/Tagout practices:

  • A steam valve is automatically turned on, burning workers who are repairing a downstream connection in the piping.
  • A jammed conveyor system suddenly releases, crushing a worker who is trying to clear the jam.
  • Internal wiring on a piece of factory equipment electrically shorts, shocking employee who is repairing the equipment.
