Fire Safety Requirements
In the event of a fire emergency inv olving 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 and fire e xtinguishers.
In addition, you should establish procedures to protect your equipment i n 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 e vent 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 . For more information about
fire extinguishers, see “Fire Suppression Equipment” on page 64.
