The following information provides a comprehensive explanation of The Control of Hazardous Energy (Lockout/Tagout) OSHA 29 CFR 1910.147 standard. Each topic is presented in easy to follow question and answer format.
Workers performing service or maintenance on machinery and equipment are exposed to injuries from the unexpected energization, startup of the machinery or equipment, or release of stored energy in the equipment.
The Lockout/Tagout standard requires the adoption and implementation of practices and procedures to shut down equipment, isolate it from its energy source(s), and prevent the release of potentially hazardous energy while maintenance and servicing activities are being performed. It contains minimum performance requirements, and definitive criteria for establishing an effective program for the control of hazardous energy. However, employers have the flexibility to develop Lockout/Tagout programs that are suitable for their respective facilities.
This tutorial summarizes for you the key components of the standard in a "plain English" format. This tutorial is intended only to guide OSHA staff in understanding aspects of the Lockout/Tagout standard, not to substitute for compliance with the plain terms of the standard. Nothing in this tutorial is intended to diminish or otherwise affect OSHA's authority to enforce the requirements of section 1910.147 of the Act, nor is it intended to create any legally enforceable right or benefit in any person.
