Fire Damper Drop Testing.
Fire dampers prevent fire and smoke spreading through ventilation systems. Regular drop testing ensures they close properly when needed, meeting legal requirements under the Regulatory Reform (Fire Safety) Order 2005. We test, maintain and certify all your fire dampers efficiently.
Fire dampers are critical safety devices that must work in an emergency. Over time, dust, debris and corrosion can prevent dampers closing fully, compromising fire compartmentation. Our engineers test each damper by triggering the release mechanism and verifying it closes completely within the correct timeframe.
We follow BS 9999 and DW145 standards, cleaning mechanisms, freeing seized components, and replacing faulty fusible links. All dampers are reset and tested again to confirm operation.
Complete fire damper compliance
We conduct comprehensive surveys to locate all fire dampers, creating accurate asset registers with grid references and photographic records. Each damper is accessed, tested, and any faults recorded. Seized dampers are freed, actuators cleaned, and worn components replaced. We test motorised dampers electrically and verify integration with fire alarm systems. Our reports satisfy building control, insurance surveyors and fire risk assessors.
