Fire Safety Requirements
This topic applies to hardware devices in the EX Series product family, which includes
EX Series switches, the EX Series Redundant Power System (RPS), and the XRE200
External Routing Engine.
This topic also applies to hardware devices in the QFX Series and to OCX1100 switches.
In the event of a fire emergency involving switches 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 extinguishers.
In addition, you should establish procedures to protect your equipment in the event of a
fire emergency. Juniper Networks productsshould 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 observedwhen you install and operate your equipment.
Fire Suppression
In the event of an electrical hazard or an electrical fire, you should first turn power off to
the equipment atthe source. Then use a Type C fire extinguisher, which usesnoncorrosive
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
