Lockout/Tagout (LOTO) is a crucial safety procedure implemented across many industries to prevent the accidental release of hazardous energy while servicing equipment. Central to this procedure are LOTO devices, tools that play an essential role in ensuring that machinery or equipment remains in a safe state during maintenance or repair. This article explores the significance of LOTO devices, how they are used, and why they are essential for maintaining a safe working environment.

What is a LOTO Device? A LOTO device refers to a physical tool or lock that is used as part of a Lockout/Tagout safety procedure to isolate machines or energy sources. The primary purpose of these devices is to prevent equipment from being accidentally powered on or operated while someone is performing maintenance. LOTO devices include a variety of items such as locks, tags, hasps, valve lockouts, and breaker lockouts. These devices ensure that workers can perform their tasks without the risk of unexpected machine startup or the release of stored energy, whether electrical, mechanical, hydraulic, or other forms of potentially hazardous energy.
