MODEL SPRINKLER IMPAIRMENT PROCEDURES

Even though sprinklers should always be in service, there will be times when it is necessary to shut off a portion of the system for repairs or renovations.  This is called impairing the system.  This also refers to any repairs or renovations to associated alarm systems.

When any fire protection system is taken off line, it is important to ensure that the system is not taken off line for longer than necessary and that all precautions are taken while the system is out of service.

If possible, all fire protection impairments should be planned in advance.  Even when the impairment is an emergency, the following precautions should be taken before and during the impairment.

1. All repair materials and equipment should be available before the system is impaired.

2. Temporary protection such as extinguishers and charged hose lines should be set up before the impairment.  Also consider back feeding and cross feeding the system.

3. Notify the public fire department and Division Emergency Organization personnel so that they are prepared to handle any emergency.

4. Conduct a fire watch in the area where protection is out of service.
