Lock Out Tag Out Propose

Nov 03, 2020

Propose

This document specifies the lockout tag out procedure that will be used when servicing and performing maintenance on machines and equipment in which the unexpected energization, startup or release of stored energy could cause injury to personnel. This document specifies the minimum requirements for the control of hazardous energy.


Scope

The isolation standard is applicable, but not limited to, all sources of potential, energy including kinetic and elastic, chemical, electrical, mechanical, materials handling and transport, pressurized systems such as hydraulic and pneumatic, chemical processes, thermal energy(eg. hot liquids, solids, gases), confined space and mobile machinery. This standard stipulates the minimum requirements to which the isolation and lock out procedure must comply.


Definitions

Affected personnel are individuals who operate or use a machine or equipment on which servicing or maintenance is being performed under lock out or tag out conditions or whose job requires him/her to work in an area in which such servicing is being performed.


Authorized personnel are individuals who are authorized to lockout or tagout machines or equipment in order to perform servicing or maintenance on those machines or pieces of equipment.


An energy isolating device is a mechanical device that physically prevents the transmission or release of energy (e.g., a manually operated electrical circuit breaker, a disconnect switch, a line valve, a block or any similar device used to block or isolate energy). 


NOTE:  Push buttons, selector switches and other control circuit type devices are not energy isolating devices.
