Fact: Over 112,000 fire dampers tested each year

Fire dampers are passive fire protection products installed in heating, ventilation and air conditioning (HVAC) ducts to prevent the spread of fire inside the ductwork through fire-resistance rated walls and floors

Fire Damper

This closes once the duct temperature reaches a high enough level to melt a fusible link, interrupting migratory airflow and resisting the passage of flame

Smoke Damper

This is a device installed in ducts and air transfer openings of an air distribution or smoke control system designed to resist the passage of air and smoke

Fire/Smoke Damper

A combined fire / smoke damper which is similar to a fire damper in fire resistance rating and also prevents the spread of smoke


BS 9999:2017 states that arrangements should be made for all fire dampers to be tested at regular intervals by a competent person on completion of the installation and at least annually, and to be repaired or replaced immediately if found faulty. 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

Our fire / smoke damper survey and testing includes:

  • Mark the location of fire / smoke dampers on building drawings (if available)

  • Dampers will be number labelled for reference in the reports

  • Reports will identify type and mechanism of dampers and provide sizes

  • Reports will identify damper accessibility

  • Provide photographic evidence of dampers opened, closed, defects / inaccessibility

  • Reports will indicate whether dampers are a pass or fail

  • Reports will identify any defects found, remedial works required and assign responsibility party

  • Single downloadable reports available 24 hours following testing procedure via Boris software client login

  • Final reports available for export in single, bulk and excel versions via Boris software client login

  • Remedial work based upon the report can be undertaken
