Hazardous Energy Control with Lockout/Tagout Standard
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.

Lockout is a technique
used to prevent the
release of hazardous
energy, or to prevent
the hazardous energy
from escaping.
A padlock is placed on
the appropriate energy
isolating device that is
in the off or closed
position.

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.

Prevent injuries related to hazardous energy by implementing Lockout/Tagout standard procedures for equipment maintenance. Lockout techniques involve isolating energy sources and using padlocks to ensure machinery stays off during servicing, reducing the risk of unexpected injuries from energy release.
