Lock Out / Tag Out

Lock-Out/Tag-Out (LOTO)

Purpose
LOTO prevents injuries from unexpected release of energy while working on equipment or systems.

Scope
LOTO applies to all hazardous energy, not just electrical, including:

  • Mechanical, hydraulic, and piping systems

  • Equipment affected by gravity

Control Measures

  • Disconnect or block energy sources

  • Unplug tools before servicing

  • Secure equipment to prevent movement

  • Follow site-specific LOTO procedures

General Rules

  • Control all energy sources

  • Never assume equipment is safe

  • Test to confirm equipment is de-energized

  • Watch for stored/residual energy

  • Apply your own lock and tag before going to work

Enforcement
Failure to follow LOTO rules may result in discipline. Ask your supervisor if you are unsure.
