Lockout Tagout

DID YOU KNOW?

OSHA estimates that proper Lockout Tagout procedures prevent 120 fatalities and 50,000 injuries annually. [2]

KNOW THE RISK

  • Hazardous energy exists in many forms: electrical, mechanical, hydraulic, pneumatic, chemical, and thermal. Any of these can be deadly when released unexpectedly. [1]
  • During servicing or maintenance of machines and equipment, uncontrolled energy can cause amputations, crush injuries, burns, or fatalities. [1]
  • Lockout Tagout (LOTO) is the method used to prevent the accidental release of energy during these tasks. It involves physically locking switches or valves and tagging them to prevent reactivation.
  • Without LOTO, someone might power up a machine while it's being repaired, creating a deadly scenario.

MITIGATE THE RISK

1. Implement a Written LOTO Program

  • Ensure procedures are documented and easy to follow. Identify all energy sources for each machine and how to safely isolate them. [2]

2. Identify Locks and Tags by Person

  • Each employee must use a personally labeled lock and tag. This prevents confusion and unauthorized removal. [2]

3. Only the Person Who Locked Out May Remove the Lock

  • This is a core rule of LOTO safety. Never remove someone else’s lock, even if the task seems complete. [2]

4. Train and Audit Regularly

  • Train employees on LOTO procedures and conduct annual audits to ensure ongoing compliance and understanding. [2]

ENERGY CONTROL REMINDER

It takes just one unexpected start to change a life forever. LOTO saves lives by ensuring machines stay off during service. If you service it, you lock it and tag it — every time.
