Introduction

It requires that hazardous energy sources be “isolated and rendered inoperative” before work is started on the equipment in question. The isolated power sources are then locked and a tag is placed on the lock identifying the worker and reason the LOTO is placed on it.

What is the purpose of the isolation lock out and hold tag process?

An effective lockout/tag out program will help prevent: Contact with a hazard while performing tasks that require the removal, by-passing, or deactivation of safeguarding devices. The unintended release of hazardous energy (including stored energy).
