FIRE HYDRANT MAINTENANCE
Fire hydrant maintenance for systems, that form part of a building’s prescribed fire safety installation, are required to be maintained in accordance with division 3 of the Building Fire Safety Regulations 2008. Adequate testing and maintenance can highlight design and installation faults. Hence their correction ensures that the system is functional and reliable.
Clause 10 of AS 2419.1-2005 sets out details of the flow rate tests to be recorded. The Registered Building Certifier(RBC) should require systems installed in accordance with this Standard to be maintained in accordance with AS 1851-2012. All flow, pump appliance and hydrostatic tests should be undertaken in accordance with AS 2419.1 Section 10 (or the equivalent criteria applicable at the time the system was installed), at the recommended intervals. For fire hydrant commissioning the appropriately licenced Fire Systems’ certifier is required to issue a form 71 together with a full report containing all relevant information in accordance with AS 2419.1-2005. All fire hydrant maintenance requires the appropriately licenced technician is required to issue a form 72. This is important as it contains all relevant information in accordance with the Queensland Development Code Mandatory Part 6.1
Although clause 4.2 of AS 2419 refers the source of water supply for fire hydrants shall be not less than that necessary to maintain appropriate flow rates required for a duration of not less than 4 hours. It is not uncommon for hydrant systems to be used for a much longer duration. Consequnetly a major fire could result in the hydrant system being in continuous use for a number of days before the fire is brought under control. The purpose of system design, installation and testing is to produce a system that is fully functional in any fire situation
