What is a "lockout procedure"?

The concept of a "lockout procedure" specifically refers to a systematic method used to ensure that electrical and mechanical equipment is de-energized during maintenance or repair operations. This is critical for maintaining safety as it prevents the accidental energization of machinery or equipment while someone is performing work on it.

Lockout procedures typically involve the use of locks and tags to control the energy sources of machines, ensuring that workers cannot inadvertently start or operate the equipment while maintenance is being conducted. This is essential in preventing workplace accidents and injuries, particularly in environments where heavy machinery or electrical systems are in use. Effective lockout/tagout programs also establish protocols for workers to follow, ensuring that they know how to safely work on equipment and that they are protected from potentially hazardous situations.

In contrast, the other options focus on different safety aspects: locking doors addresses unauthorized access, securing tools after use pertains to tool management, and storing hazardous materials deals with environmental and chemical safety. While all these practices contribute to overall safety in the workplace, they do not specifically address the processes involved in ensuring equipment is safely de-energized for maintenance tasks.
