In the event of an electrical hazard or an electrical fire, you should first turn power off tothe equipment at the source. Then use a Type C fire extinguisher, which uses noncorrosivefire retardants, to extinguish the fire.Fire Suppression EquipmentType C fire extinguishers, which use noncorrosive fire retardants such as carbon dioxideand Halotron™, are most effective for suppressing electrical fires. Type C fire extinguishersdisplace oxygen from the point of combustion to eliminate the fire. For extinguishing fireon or around equipment that draws air from the environment for cooling, you should usethis type of inert oxygen displacement extinguisher instead of an extinguisher that leavesresidues on equipment.Do not use multipurpose Type ABC chemical fire extinguishers (dry chemical fireextinguishers). The primary ingredient in these fire extinguishers is monoammoniumphosphate, which is very sticky and difficult to clean. In addition, in the presence of minuteamounts of moisture, monoammonium phosphate can become highly corrosive andcorrodes most metals.Any equipment in a room in which a chemical fire extinguisher has been discharged issubject to premature failure and unreliable operation. The equipment is considered tobe irreparably damaged.NOTE: To keep warranties effective, do not use a dry chemical fire extinguisherto control a fire at or near a switch running Junos OS.
