TypeC fire extinguishers, which use noncorrosive fire retardants such as carbon dioxide
andHalotron™,aremosteffectiveforsuppressingelectricalfires.TypeCfireextinguishers
displace oxygen from the point of combustion to eliminate the fire. For extinguishing fire
on or around equipment thatdraws air from the environment forcooling, youshould use
thistypeof inert oxygendisplacementextinguisherinstead ofan extinguisherthatleaves
residues on equipment.
Do not use multipurpose TypeABC chemical fire extinguishers (dry chemical fire
extinguishers). The primary ingredient in these fire extinguishers is monoammonium
phosphate,whichisverystickyanddifficulttoclean.Inaddition,inthepresenceofminute
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.
