This British Standard gives recommendations for the design, installation, components, water supplies and backflow protection, commissioning, maintenance and testing of fire sprinkler systems installed for life safety purposes with additional benefits for property protection in residential and domestic occupancies.
Residential occupancies, for multiple occupation, not exceeding 20 m in height, include apartments, residential homes, houses of multiple occupancy (HMOs), blocks of flats, boarding houses, aged persons homes, nursing homes, residential rehabilitation accommodation and dormitories.
Domestic occupancies include individual dwelling houses, individual flats, maisonettes and transportable homes.
NOTE Care should be taken particularly when specifying residential sprinkler systems that the fire/fuel loading in any given occupancy does not exceed that which would normally be found in a residential living room, kitchen and bedrooms. If the fire/fuel loading is greater than that of a conventional residential occupancy then consideration should be given to installing a sprinkler installation in accordance with BS 5306-2/BS EN 12845. Key indicators of high fire loading include significant volumes of video tapes, books, paper and institutional catering facilities.
