For example, use a Class A extinguisher on a Class A fire. See also fire classifications.Portable fire extinguishers are classified for use on certain classes of fires and are rated within that class for relative extinguishing effectiveness at a temperature of plus 70°F by nationally recognized testing laboratories. This is based upon fire classifications and fire extinguishment potentials as determined by fire tests.Note:The classification and rating system described in this section is used by Underwriters' Laboratories, Inc., and Underwriters' Laboratories of Canada, and is based on extinguishing preplanned fires of determined size and description as follows:Extinguisher rating (see also "extinguisher classification")The numerical rating, such as 2A, given to an extinguisher that indicates the extinguishing potential of the unit based on standardized tests developed by Underwriters' Laboratories, Inc.Fire brigadeAn organized group of employees whose primary employment is other than firefighting but who are knowledgeable, trained, and skilled in specialized firefighting operations based on site-specific hazards present at a single commercial facility or facilities under the same management.Fire classificationsFires are classified based on the types of burning materials:Incipient fire stageA fire in the beginning stage that can be controlled or put out by portable fire extinguishers, or small hose systems, without the need for protective clothing or breathing apparatus.InspectionA visual check of fire protection systems and equipment to ensure they are in place, charged, and ready for use if there is a fire.Interior structural firefightingThe physical activity of suppressing fire, rescuing people, or both, inside buildings or enclosed structures involved in a fire that is past the incipient stage.MaintenanceServicing fire protection equipment and systems to ensure they will perform as expected if there is a fire.
