General Fire Safety Requirements
In the event of a fire emergency involving network devices, the safety of people is the
primary concern. Establish procedures for protecting people in a fire emergency, provide
safety training, and properly provision fire-control equipment and fire extinguishers.
In addition, establish procedures to protect your equipment in 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 you observe all local fire, safety, and
electrical codes and ordinances 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.
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 devices. 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.
