Fire Damper Drop Testing

Fire Damper inspections and Drop Testing are critical for fire safety.

Fire and smoke dampers are fitted in ductwork to prevent the spread of fire through the use of fire-resistance rated walls and floors. Fire dampers are responsible for slowing or stopping a fire inside of a Heating, Ventilation and Air Conditioning (HVAC) system, helping to minimise any damage to the structure itself and most importantly to protect the people within the building.

Why do Fire and Smoke Dampers fail?

Foreign materials and particulates such as dirt, combustible dust, and debris can accumulate within the ductwork. These foreign materials can impair the proper functioning of the fire dampers, leaving the building occupants at risk in the event of a fire. Typical issues also include obstructions or damage to the fire damper, poor hinges or parts, misalignment, bent tracks, rust, or damaged frames or blades.

It might take only one faulty damper to allow the spread of a fire, therefore it is imperative to allow regular checks to be carried out.

Fire Damper Inspections

The British Standard 9999:2017 gives clear guidance that covers routine inspection and maintenance of ventilation and air conditioning ductwork and states that all fire dampers should be tested not exceeding a 12 months period.

Hydro-X Air also complies with the Health Technical Memorandum (HTM) 03-01: Specialised ventilation for healthcare premises Part B: Operational management and performance verification which calls for fire dampers in hospitals to be tested every 12 months.

As the building owner / responsible person on-site you need to ensure that all fire and smoke dampers within your building(s) are located, serviced and tested. Hydro-X Air can help to ensure you meet the regulatory requirements and support you in compiling an asset list and schedule to ensure regular checks are carried out for continued safe operation.
