What is considered an energy source in Lockout/Tagout practices?

In Lockout/Tagout practices, an energy source encompasses any form of energy that can potentially cause the unexpected startup of machinery or equipment during maintenance or servicing. This includes various types of energy sources like mechanical, pneumatic, and chemical.

Mechanical energy is associated with moving parts or machines, which can cause injury if they unexpectedly activate. Pneumatic energy involves compressed air, which can also lead to unexpected movement of machinery or components. Chemical energy pertains to substances that can create hazardous conditions when released or activated, creating risks for workers.

Since Lockout/Tagout is designed to ensure that all forms of energy are properly controlled to prevent accidental release, recognizing that all of these energy sources—mechanical, pneumatic, and chemical—are critical is essential for maintaining safety in the workplace. This comprehensive approach is vital to safeguarding workers from potential hazards during maintenance and servicing activities.
