lockoutsysteem

A lockout system, often referred to as a lockout/tagout (LOTO) system, is a set of established procedures used in industrial and commercial settings to ensure that dangerous machines are properly shut off and rendered inoperable before maintenance or servicing work is performed. The primary goal of a lockout system is to prevent accidental startup or release of stored energy that could cause injury or death to workers.

The lockout procedure involves affixing a lock and a tag to the energy isolating device (such as a circuit breaker or valve) that controls the equipment. The lock physically prevents the device from being operated, while the tag provides information about the worker performing the lockout, the reason for the lockout, and the date and time. Only the authorized employee who applied the lock and tag can remove it.

Tagout, a related concept, involves placing a tag on the energy isolating device to warn other workers that the equipment is being serviced and should not be operated. In many cases, both lockout and tagout are used in conjunction to provide a higher level of safety.

The implementation of a lockout system is a critical component of workplace safety regulations in many countries. Employers are typically required to develop, implement, and enforce a written lockout/tagout program, which includes providing training to all employees who may be affected by the procedure. This ensures that all personnel are aware of the hazards associated with unexpected energization and the procedures to prevent them.
