and that all local fire, safety, and electrical codes and ordinances be observed
when you are installing and operating your equipment.
Fire Suppression
In the event of an electrical hazard or an electrical fire, first unplug
the power cord. (For shutdown instructions, see “Powering a Services
Router On and Off” on page 90.)
Then, use a Type C fire extinguisher, which uses noncorrosive fire retardants,
to extinguish the fire. For more information about fire extinguishers,
see “Fire Suppression Equipment” on page 74.
Fire Suppression Equipment
Type C fire extinguishers, which use noncorrosive fire retardants such as carbon
dioxide (CO2) 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 equipment. 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.
NOTE: To keep warranties effective, do not use a dry chemical fire extinguisher to
control a fire at or near a Juniper Networks router. If a dry chemical fire extinguisher
is used, the unit is no longer eligible for coverage under a service agreement.
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.
We recommend that you dispose of any irreparably damaged equipment
in an environmentally responsible manner.
