SAFETY WARNINGS
LOCKOUT/TAGOUT PROCEDURES
The Occupational Safety and Health Administration requires that, in addition to posting safety warnings and
barricading the work area, the power supply has been locked in the OFF position or disconnected. It is mandatory
that an approved lockout device is utilized. An example of a lockout device is illustrated. The proper lockout
procedure requires that the person responsible for the repairs is the only person who has the ability to remove the
lockout device.
In addition to the lockout device, it is also a requirement to tag the power control in a manner that will clearly note
that repairs are under way and state who is responsible for the lockout condition. Tagout devices have to be
constructed and printed so that exposure to weather conditions or wet and damp locations will not cause the tag to
deteriorate or become unreadable.
RITE-HITE Corporation does not recommend any particular lockout device, but recommends the utilization of an
OSHA approved device (refer to OSHA regulation 1910.147). RITE-HITE Corporation also recommends the review
and implementation of an entire safety program for the Control of Hazardous Energy (Lockout/Tagout). These
regulations are available through OSHA publication 3120.
This is the highest level statement. Failure to
follow the listed instructions will most likely
result in severe injury or death.
IMPORTANT is used to draw attention
to a procedure that needs to be followed to
prevent machine or property damage.
When working with electrical or electronic
controls, make sure that the power source has
been locked out and tagged according to OSHA
regulations and approved local electrical codes.
This is a statement of serious hazard. Failure to
follow the listed instructions could place the
individual at risk of serious injury or death.
The statements used with this level of
warning deal with a safe operating
procedure. If the procedure is ignored, the
possibility of personal injury may exist.
