Lockout tagout padlocks are locks that are made and used specifically for lockout tagout programs and procedures. They are utilized to securely lock a LOTO device, such as a valve lockout or a circuit breaker lockout. This prevents a source of hazardous energy from being turned on or re-energized during maintenance procedures.
These padlocks are different from ordinary hardware store padlocks. LOTO padlocks are designed to be compliant with OSHA standard 1910.147 and are made to be hardwearing, impact-resistant, non-conductive, and chemical- and corrosion-resistant. They are also able to withstand high and low temperatures and harsh environments.
