Hazard Management Systems - L.O.T.O - Lock Out Tag OutPurpose

The reasons for a LOTO system are to avoid;

  • Contact with a hazard while performing tasks that require the removal, by-passing, or deactivation of safe guarding devices
  • The accidental release of stored energy
  • The unintentional start-up or motion of machinery, equipment, or processes

Removal of the L.O.T.O

ONLY the authorized individual who placed the lock and tag onto the system is the one who is permitted to remove them.  This procedure helps make sure the system cannot be started up without the authorized individual’s knowledge.  HMS Ltd is able to train and develop a L.O.T.O. system that can meet operational demands and have the ability to design a policy or procedure in the event of a L.O.T.O. abandonment by an individual(s).
