FIRE PROTECTION SYSTEMS

The standards of the National Fire Protection Associa-tion (NFPA) contain the criteria under which most fireprotection systems in the United States of America aredesigned and installed.

NFPA 25-1995Inspection, Testing and Maintenanceof Waterbased Fire Protection Systems assembles detailedinspection, testing and maintenance recommendationsfrom several existing standards. NFPA 25 does not includesuppression systems using chemical and gaseous agents,portable fire extinguishers, exit safety components, alarmand detection systems, in-plant fire apparatus and othersystems and equipment.

The suggested frequencies listed here are for water-

based systems only. Contact your local fire departmentand your insurance carrier for review of your inspectionsystem before implementing it. They may have require-ments that you are unaware of.
