Lockout/Tagout and Machine Safety

Machines and equipment contain hazardous energy which can cause injury to employees if it's not appropriately contained. De-energization and lockout/tagout prevent the release of this energy to protect workers.

Every year in B.C., workers are significantly injured or even killed when machinery is not properly de-energized and locked out. These accidents can be significant and life-altering and include:

  • severed fingers and limbs
  • crushing injuries
  • electric shock
  • burns

These accidents are preventable with an effective lockout/tagout program. Learn to identify when lockout/tagout is required, the associated risks, and preventative actions with the resources and tools below.

Lockout Tagout

Toolbox Talk

Lockout/tagout is a safety practice. Dangerous machinery is shut off and can’t be started again before maintenance work is done. Lockout/tagout protects workers from serious injury or death while working on equipment.

De-energization and Lockout


For workers and supervisors: understand what hazardous energy is and identify it in your workplace. Learn to apply the Occupational Health and Safety Regulations (OHSR) requirements for lockout and de-energization to prevent the release of hazardous energy to prevent injuries and property damage.
