Valve Lockout Tagout (LOTO) is a critical safety procedure widely adopted in industrial settings, particularly in environments where equipment and machinery pose potential hazards to workers. This procedure, which involves the use of locks and tags to prevent accidental activation of valves and machinery during maintenance or repair work, plays a vital role in safeguarding workers from injuries or fatalities caused by unintended equipment operation. This article explores the importance, process, and benefits of Valve Lockout Tagout, focusing on its implementation in industrial facilities.

What is Valve Lockout Tagout? At its core, Valve Lockout Tagout is a method of controlling hazardous energy sources in machinery, specifically through the use of locks and tags on valve controls. The term “Lockout” refers to physically locking a valve or energy-isolating device in an off or safe position, while “Tagout” involves attaching a warning tag to the device to inform other personnel that the equipment is being serviced and must not be operated. This combined approach ensures that a machine or valve cannot be accidentally turned on, preventing accidents caused by unexpected movements or energy releases.
