What is a lockout device?

A lockout device is specifically designed to prevent the operation of a machine or equipment. This device is a physical mechanism that ensures energy-isolating devices are secured in a safe position, thereby inhibiting accidental or unauthorized operation during maintenance, servicing, or repair activities. The primary purpose of this device is to safeguard workers from the risks associated with unexpected machine startup or the release of stored energy, which could lead to injuries.

Effective lockout/tagout procedures require that these devices be used alongside tags that communicate to others that maintenance is occurring, but the key factor of a lockout device is its ability to physically block the operation of the machinery. This distinction emphasizes the importance of using a lockout device as a crucial part of workplace safety protocols to ensure a safe environment during maintenance tasks.
