Lockout/Tag out Safety
Awareness Training
LockLockout/Tagout/Tagoutout
�� Lock out:the placement of a lockout device (lock) on an energy isolating device in accordance with an established procedure.
�� Tag out:the placement of
special tags on equipment energy isolating devices to warn employees not to operate
LockLockout/Tagout/Tag outout
LOCKOUT/TAGOUT SHOULD BE USEDWHEN:�� A worker must remove or bypass a guard or
safety device�� A worker must place any part of body
where it could be caught by moving machinery
�� Clearing jammed mechanisms�� Unexpected start up or release of energy
could cause injury�� Cleaning or oiling machinery with moving parts�� Repairing electrical circuits

ElectricalElectrical HazardsHazards
•• As low as 30 volts can carry enough current to kill
•• As low as 1 amp of electric current can stop a person’s heart
�� Electrical burns:– Are the result of the electric current flowing in the tissues and
may be either skin deep or may affect deeper layers (muscles, bones, etc.) or both
�� Arc burns:– Are the result of high temperatures produced by electric
arcs or by explosions close to the body causing burns and blisters
�� Thermal contact burns:– Normally experienced from the skin's contacting hot
surfaces of overheated electric conductors, conduits, or other energized equipment

�� Valve Covers - for LOTOof Valves
�� Plug Buckets - for electrical plugs
WhoWho CanCan Lockout?Lockout?
�� Any trained and authorized employee who has to perform work or maintenance on a piece of equipment.
�� Each person working on the equipment must place their own locks and tags to ensuretheir safety.
