7262 7867 X AS 1851.4—1992 PREFACE This Standard was prepared by the Standards Australia Committee on Fire Hydrant Installations to supersede AS 1851.4—1988 For effective operation of fire hydrants in an emergency, it is essential that regular testing and maintenance be carried out on the fire hydrant installation This Standard includes requirements for such regular testing and maintenance, and precautions to be taken when an installation is rendered inoperative The changes from the 1988 edition include a revision of the maintenance procedures for fire hydrant installations, changes to the sample log book record cards and a checklist summary of maintenance schedules Where town main water supplies are curtailed for any protracted period, e.g in time of drought, special attention should be given to all other fire protection equipment or system, including alternative water supplies It is recommended that a watchman be on duty whenever water supplies are curtailed to an installation
