SHELTER FIRE PROTECTION EQUIPMENT (Continued)

In addition to the alarms, a fire control agent (halon) contained in storage bottles (7) is released if a heat sensor or

Manual Pull Station is activated.

WARNING

Avoid halon dispensing nozzles (8) and (9)

when a fire alarm sounds. Halon is released at

pressures great enough to cause damage to

eyesight or cause injuries from sudden

personnel reactions.

NOTE

Any shelter door locked on the outside may be

released from the inside in an emergency

situation. First, make sure that locking pin (10)

is removed. Then, unscrew thumbscrew (11) to

give the handle a sharp downward thrust to

break the seal outside.

The halon release is delayed for 20 seconds to allow time for personnel to leave the shelters and close the doors. The

halon agent is dispensed at high pressure through nozzles (8) and (9) in both the Computer and Trainer Shelters.

To prevent the spread of electrical fires, main power from the shelter distribution boxes is automatically shut off when an

alarm is sounded. When this occurs the emergency lighting (on battery supply) turns on.

Hand-held halon fire extinguishers (12) are also located at each shelter exit. They are for use on small, contained fires

discovered before an alarm is sounded.
