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.

Fire Suppression

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, which uses noncorrosive
fire retardants, to extinguish the fire. For more information about fire extinguishers,
see "Fire Suppression Equipment" on page 131.

Fire Suppression Equipment

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.
NOTE: To keep warranties effective, do not use a dry chemical fire extinguisher to
control a fire at or near a Juniper Networks router. 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.
