What are Lockout/Tagout Devices?

Lockout/tagout devices are the tools that physically isolate hazardous energy during maintenance: safety padlocks, lockout hasps, valve and circuit-breaker lockouts, cable lockouts, and group lock boxes. Each secures a specific energy-isolating point so equipment can't be re-energized until every worker removes their lock.

Lockout/tagout devices can be used for a number of different types of applications regarding energy release. Those include:

• Electrical circuit breakers that are manually operated
• Disconnect switches
• Line valves
• Blocks
• Other devices that are used to adequately block and isolate energy sources, whether it be hydraulic, pneumatic, etc.

Lockout/tagout devices are essential for workplace safety and regulatory compliance. The Occupational Safety and Health Administration (OSHA) requires and enforces the use of LOTO devices. OSHA's standard 29 CFR 1910.147 outlines the practices and procedures necessary to disable machinery and equipment, preventing the release of hazardous energy during servicing and maintenance. Employers are responsible for developing, implementing, and enforcing a LOTO program that protects employees from these hazards.

There are quite a few different types of LOTO devices that a company can use for machines and equipment. Becoming familiar with these devices and the way they work can help ensure you pick the right one for your facility.
