Fire Safety Requirements
In the event
of a fire emergency involving routers and other network equipment, the safety
of people is the primary concern. You should establish procedures for protecting people in
the event of a fire emergency, provide safety training, and properly provision fire-control
equipment a
nd fire extinguishers.
In addition, you should establish procedures to protect your equipment in the event o f 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 o
rdinances be observed when installing and operating your equipment.
Fire Suppression
In the eve
nt 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 th e fire. For more information about fire extinguishers, see
“Fire Sup
pression Equipment” on page 41.
Fire Suppression Equipment
Type C fir
e 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 exti
nguishing 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 leave residues on equipment.
Do not use multipurpose Type ABC chemical fire extinguishers (dry chemical fire
extinguishers) near Juniper N etworks equipment. The primary ingredient in these fire
exting
uishers is monoammonium phosphate, which is very sticky and difficult to clean .
