SAFETY WARNINGS

LOCKOUT/TAGOUT PROCEDURES

The Occupational Safety and Health Administration (OSHA) 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 PRODUCTS 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 PRODUCTS

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 a statement of serious hazard. Failure to

follow the listed instructions could place the

individual at risk of serious injury or death.

WARNING

This is the highest level statement. Failure to

follow the listed instructions will most likely

result in severe injury or death.

DANGER

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.

CAUTION

IMPORTANT is used to draw attention

to a procedure that needs to be followed to

prevent machine or property damage.

IMPORTANT

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.
