What is a fire damper; commonly referred to as a FD is the means of preventing the spread of fire through the ventilation system. There are many different types of FD from fusible link, spring loaded and motorized.
How often should a fire damper be serviced; Testing of FD should not exceed 12 month intervals but it’s advisable to consult with local Authority and building insurer as they may indicate tests are carried out on a more frequent basis.
From April 2006, it became an offence if systems (including mechanical ventilation systems) are not maintained from a fire risk prospective and in the event of personal injury or death from a fire associated with a poorly maintained system (section 17 of the RRFSO), charges of corporate liability or manslaughter may be brought against the responsible person.
The RRFSO specifically;
- -- Equipment and devices are subject to a suitable system of maintenance and are maintained in an efficient state, in efficient working order and in good repair.
BS 9999 fire damper maintenance legislation;
Fire damper maintenance states that all fire dampers must be tested by a competed person after they have been installed and at regular intervals not exceeding two years. If you have had spring-operated fire dampers installed in your ducting, then you will need to have these tested at least every 12 months or even more frequently if they are installed in an area that is affected by high levels of dust or pollution. According to HTM03-1 fire dampers in hospitals must also be tested every twelve months.
- -- Spring loaded fire dampers – annually
- -- Fusible link fire damper – annually
- -- Motorized fire damper – 2 years
Common poor maintance issues:
- -- Faulty FD close unexpectedly obstructing air flow
- -- Buildup of dust and debris prevent closing
- -- Damaged springs prevent closing
- -- Damaged motors prevent closing
- -- Obstructions prevent closing
- -- Collapsed blades
- -- Spread of fire
Broken fire damper spring prevent closure
Buildup of dust/ debris preventing closure
Anyone of the above could have a major impact on life safety contributing to the spread of fire, heat, impede evacuation and preventing access of emergency services.
Benefits of an HVAC hygienics testing programme:
- -- Meet local Authority and insurance requirements
- -- Free from dust, debris and obstructions
- -- Prevent obstruction of air flow
- -- Advise on any damaged FD
- -- Ensure full working order
- -- Ensure activation on fire
* Will provide a service log for each and every FD tested and issue an easily identifiable serial number for future reference.
*Will where possible fix any faulty fire dampers found.
Of course, performing great maintenance on fire dampers means going a little deeper, but at HVAC HYGIENICS every little extra effort is always worth it.
