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.
