Fire Safety Requirements
In the event of a fire emergency involving devices and other network equipment, the
safety of people is the primary concern. Establish procedures for protecting people in
the event of a fire emergency, provide safety training, and properly provision fire control
equipment and fire extinguishers.
In addition, establish procedures to protect your equipment in the event of a fire
emergency. Juniper Networks products should be installed in an environment suitable
for electronic equipment. We recommend that fire suppression equipment be available
in the event of a fire in the vicinity of the equipment and that all local fire, safety, and
electrical codes and ordinances be observed when installing and operating your
equipment.
In the event of an electrical hazard or an electrical fire, first turn power off to the equipment
at the source. Then use a Type C fire extinguisher to extinguish the fire. Type C fire
extinguishers, which use noncorrosive fire retardants such as carbon dioxide (CO
2
) and
Halotron, are most effective for suppressing electrical fires. Type C fire extinguishers
displace the oxygen from the point of combustion to eliminate the fire. For extinguishing
fire on or around equipment that draws air from the environment for cooling, use this
type of inert oxygen displacement extinguisher instead of an extinguisher that leave
residues on equipment.
Do not use multipurpose Type ABC chemical fire extinguishers (dry chemical fire
extinguishers) near Juniper Networks equipment. The primary ingredient in these fire
extinguishers is monoammonium phosphate, which is very sticky and difficult to clean.
In addition, in minute amounts of moisture, monoammonium phosphate can become
highly corrosive and corrodes most metals.
Any equipment in a room in which a chemical fire extinguisher has been discharged is
subject to premature failure and unreliable operation. The equipment is considered to
be irreparably damaged.
