AS 1851 is the Australian Standard for the Maintenance of Fire Protection Systems and Equipment. This standard sets out the requirements for the maintenance, inspection, testing, and reporting of fire protection systems and equipment in Australia. It covers a wide range of fire protection systems and equipment, including fire alarms, fire extinguishers, fire hose reels, fire sprinklers, fire suppression systems, and emergency and exit lighting. The purpose of AS 1851 is to ensure that fire protection systems and equipment are maintained to a high standard, so that they are always in good working order and ready to use in the event of a fire. This standard helps to minimize the risk of injury or damage, and to ensure that the fire protection systems and equipment are able to perform as intended, in the event of a fire. AS 1851 is reviewed and updated regularly, to ensure that it remains current with the latest developments in fire protection technology and best practices. The standard is used by fire protection professionals, building owners and managers, and insurance companies, to ensure that fire protection systems and equipment are properly maintained and tested.
