  • Lockout is a technique used to prevent the release of hazardous energy, or to prevent the hazardous energy from escaping.
  • A padlock is placed on the appropriate energy isolating device that is in the off or closed position.
3
The “Fatal Five” Main Causes of
Lockout/Tagout Injuries
  • Failure to stop equipment
  • Failure to disconnect from power source
  • Failure to dissipate (bleed, neutralize) residual energy
  • Accidental restarting of equipment
  • Failure to clear work areas before restarting
4
Definitions
  • Authorized Employee - one who locks out machines or equipment in order to perform the servicing or maintenance on that machine or equipment.
  • Affected Employee - one whose job requires him/her to operate or use a machine or equipment on which servicing or maintenance is being performed under lockout, or whose job requires him/her to work in an area in which such servicing or maintenance is being performed.
5
Definitions, cont.
  • Energy Isolating Device - A mechanical device that physically prevents the transmission or release of energy.
  • Energy Control Procedure - Safety program adopted by the employer that includes energy control procedures plus provisions for inspecting the procedures and training employees for lockout/tagout.

Special Situations
  • Servicing lasts longer than one shift.
  • Contractors are performing service or maintenance at your workplace
