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

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.
