This part of ISO 11602 specifies the inspection, maintenance, and periodic testing of portable and wheeled fire extinguishers.

Portable fire extinguishers are intended as a first line of defence against fires of limited size. They are needed, even if the property is equipped with automatic sprinklers, standpipe and hose, or other fixed protection equipment.

This part of ISO 11602 is not applicable to permanently installed systems for fire extinguishment, even though portions of such systems may be portable (such as hose and nozzles attached to a fixed supply of extinguishing media).

Extinguishers for use on board aircraft, watercraft and vehicles are considered to be outside the scope of this part of ISO 11602.
