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 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 switch. 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.
