A safety procedure used to isolate hazardous energy sources before maintenance or servicing work begins.
Lockout/Tagout (LOTO) is a safety procedure that prevents the unexpected release of hazardous energy by isolating equipment and securing energy-isolating devices with locks and warning tags before maintenance, inspection or servicing activities are performed. It protects personnel by ensuring equipment cannot be energized until all work has been completed and authorized.
Lockout/Tagout is a fundamental safety control that protects personnel from hazardous energy during maintenance and operational activities.
LOTO procedures typically address electrical, mechanical, hydraulic, pneumatic, thermal, chemical and other stored energy sources. Specific requirements vary by jurisdiction and organizational safety procedures.
Lockout/Tagout isolates hazardous energy before work begins, whereas Permit to Work authorizes and controls the overall work activity.
