The Regulatory Reform (Fire Safety) Order 2005 places a duty of care on the building owner/occupier to take such general fire precautions as will ensure, so far as reasonably practical, the safety of the building and safety of the people within it. Section 17 of this Order deals with maintenance of systems to control the fire risk and requires that they are subject to a suitable system of maintenance and are maintained in an efficient state, in efficient working order and in good repair.
British Standards give a good definition of ‘suitable system’. British Standard 9999:2017 Annex W.1 gives clear guidance that all fire dampers should be tested at regular intervals not exceeding 2 years and that spring operated fire dampers should be tested every 12 months and at greater frequencies if in a dust-laden environment.
All fire and smoke dampers within your building(s) should be located, serviced and tested. Then a schedule created for regular checks to ensure their continued safe operation.
