Fire Suppression Equipment

Type C fire extinguishers, which use noncorrosive fire retardants such as carbon dioxide
(CO

) 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.

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.
