The term ZMS stands for Zero Mechanical State, which is a critical concept in lockout/tagout (LOTO) procedures used to ensure the safety of workers when maintaining or servicing machinery and equipment. Achieving a Zero Mechanical State means that all hazardous energy sources have been effectively isolated and rendered inoperable before maintenance work begins. This encompasses not only electrical energy but also mechanical energy, which could pose serious risks if the machinery were to inadvertently start up or release stored energy while someone is working on it.

This concept is central to preventing injuries and maintaining a safe working environment, as it emphasizes the importance of ensuring that equipment is completely de-energized and safe to interact with. Properly implementing the Zero Mechanical State helps protect workers from unexpected machine motion, which is a leading cause of workplace accidents in maintenance situations.
