The CLP Site Air Services team of surveyors carry out fire / smoke damper testing to comply with BS5588-9 Code of practice for ventilation and air conditioning ductwork.
This also includes BS9999, which states that fire dampers should be cleaned and maintained at intervals as stated below.
Fire dampers are crucial passive fire protection products used in HVAC ducts to prevent the spread of fire inside the ducting system through fire- resistant rated walls and floors. In the event of a rise in temperature, the fire damper closes which usually is activated by a thermal element. This thermal element melts at higher than ambient temperatures but low enough to indicate the presence of fire and or sensing of heat or smoke, allowing the springs to close the damper blades.
Fire / smoke dampers are open most, if not all the time, it is vital that these will still close effectively when required to do so. By providing a barrier beyond which the fire cannot pass through, effectively fire dampers are saving lives.
Regular fire damper testing (also known as drop testing) as well as cleaning and maintenance is both a legal requirement and a critical part of building fire safety management. At CLP Site Air Services, we offer a fire damper testing, cleaning and maintenance service in accordance with BS9999:2008. This gives guidance for the two main types of fire dampers which are the spring-loaded style. These should be drop tested, cleaned and maintained at intervals of no greater than 12 Months. The non-spring-loaded model must be drop tested, cleaned and maintained at least every 24 Months.
A photographic report and certificate will be issued upon completion.
