What is the purpose of Lock Out - Tag Out procedures?

The purpose of Lock Out - Tag Out (LOTO) procedures is fundamentally centered on securing energy sources when working on equipment. This safety protocol is critical in preventing accidental or unexpected energization of machinery while maintenance or repair work is being conducted. By locking and tagging equipment, workers ensure that no one else can inadvertently activate the machine, which could lead to serious injuries or accidents.

LOTO procedures involve the use of locks and tags that indicate maintenance is being performed, which serves as a clear and effective warning to anyone who may be working on or near that equipment. This system promotes a safe working environment and protects workers from potential hazards associated with energized machinery.

While assisting in equipment maintenance and improving safety overall can be seen as secondary benefits, the core intent of LOTO is to manage hazardous energy. Hence, the focus on securing energy sources clearly defines the primary objective of these procedures.
