FIRE DAMPER
By providing a barrier beyond which the fire cannot pass, effective fire dampers save lives; so regular fire damper testing (known as drop testing) as well as fire damper cleaning and maintenance is both a legal requirement and a critical part of building fire safety management.
British Standard 9999:2008 covers Inspection and maintenance of ventilation and air conditioning ductwork and states that: “… all fire dampers to be tested by a competent person on completion of the installation and at regular intervals not exceeding 2 years. Spring-operated fire dampers should be tested annually and fire dampers situated in dust-laden and similar atmospheres should be tested much more frequently at periods suited to the degree of pollution”.
