In addition, you should 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.
Fire Suppression
In the event of an electrical hazard or an electrical fire, you should first turn power off to
the equipment at the source. Then use a Type C fire extinguisher, which uses noncorrosive
fire retardants, to extinguish the fire.
Fire Suppression Equipment
Type C fire extinguishers, which use noncorrosive fire retardants such as carbon dioxide
and Halotron™, are most effective for suppressing electrical fires. Type C fire extinguishers
displace 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, you should use
this type of inert oxygen displacement extinguisher instead of an extinguisher that leaves
residues on equipment.
Do not use multipurpose Type ABC chemical fire extinguishers (dry chemical fire
extinguishers). The primary ingredient in these fire extinguishers is monoammonium
phosphate, which is very sticky and difficult to clean. In addition, in the presence of 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.
NOTE: To keep warranties effective, do not use a dry chemical fire extinguisher
to control a fire at or near a Juniper Networks switch or other network device
provided by Juniper. If a dry chemical fire extinguisher is used, the unit is no
longer eligible for coverage under a service agreement.
We recommend that you dispose of any irreparably damaged equipment in an
environmentally responsible manner.
