Hazardous energy appears in the workplace in
the form of electrical, mechanical, pneumatic, hydraulic and
thermal energy and includes chemical, water, steam and gaseous
energy systems. Lockout/Tagout procedures prevent the
unexpected energization, start up or release of stored energy that
could cause injury to employees working on equipment.
The purpose of this program is to identify the practices and procedures necessary to shut down and lock out or tag out machines and equipment. It also requires that employees receive training in the Lockout/Tagout program before they are authorized to perform service and maintenance requiring Lockout/Tagout.
