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 device. 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.
