Fire Damper Testing in Essex

Fire dampers are crucial passive fire protection products that help to prevent the quick and dangerous spread of fire and smoke through building ductwork which penetrate fire and smoke barriers.

For Safe, Compliant Buildings

Do you own, manage or are in charge ofoversee a property, shop, buildings or premises? If so, have you ever thought about what could happen if a fire was to break out?

Most people, employers and businesses are aware of their typical fire prevention, detection, protection and suppression systems such as smoke alarms, fire extinguishers and sprinklers etc. They also know where they are located and how often they must be checked, tested and maintained in order to ensure that they are in full working order and compliant with the relevant fire safety standards.

However, when it comes to fire dampers, because of their location hidden away inside ductwork, it is not unusual for them to go completely ignored, unchecked and untested for years at a time which is extremely dangerous, not to mention against the law.

At Swift Fire Compliance, our team of dedicated, expert engineers carry out a professional fire damper testing and maintenance service that works to ensure your building and everyone who uses it is safe.

What is the purpose of fire dampers?

Fire dampers are crucial passive fire protection products that are fitted inside heating, ventilation, and air conditioning (HVAC) systems. They help to prevent the spread of smoke and fire inside the ductwork where they pass through fire barrier walls, doors and floors. Without functioning dampers in place, smoke and fire can pass through the ductwork and spread rapidly to other areas of the building.

Fire dampers have blades that open and close and are designed to act a bit like roller shutters. When not in use they remain open, allowing the free flow of air throughout the ducts until they are activated either thermally or electrically, triggering the damper so the blades quickly slam shut.

Sealing the duct off creates a barrier which works to;

  • Hold back the fire from passing through the fire resistant barrier
  • Prevent smoke and fire from travelling through ductwork to other areas of the building
  • Maintains the integrity of fire escape routes
  • Gives those inside more time to safely evacuate
  • Provides vital extra minutes needed for emergency services to arrive

Why do fire dampers need testing?

Fire dampers are a crucial part of fire safety for any large building from warehouses, public buildings, factories and commercial spaces to offices, flats and HMO’s. They need to be kept in top working order because if not, they could be the difference between life and death for those who live, work or visit the property.

Not only are fire dampers tucked away inside ductwork where they cannot be easily seen to check , but they remain open constantly, unless they are triggered by a fire. This means that there is no way to tell that they are working and will close properly if they are needed, and a fire breaks out. The only way to check that they are working is to carry out regular checks, tests and maintenance.

FAQ’s

Professional fire damper testing and maintenance should include;

  • Locating all fire dampers and creating an inventory of where they all are in the building.
  • Inspecting each damper for damage, obstructions and corrosion.
  • A drop test on every fire damper to check their effectiveness.
  • A report on the individual condition of each fire damper.
  • Photographic evidence of the fire dampers condition both before and after testing.
  • Maintenance where appropriate – cleaning and lubricating channels and runners etc.
  • Recommendations for corrective or remedial action on anything that needs to be repaired or replaced.
  • Reset all fire dampers.
  • Inspection test results including any drawings and annotated details.
  • A comprehensive report containing details on all locations, maintenance, suggested repairs, replacements, recommendations and detailed exception reports for any failures that were found.
In accordance with the Regulatory Reform (Fire Safety) Order all fire safety devises must be regularly tested, “it is a legal requirement to test fire dampers at regular intervals and in accordance with fire safety in the design, management and use of buildings code of practice (BS:9999 2017), using a method known as drop testing”.

This states that all fire dampers must be tested by a competent person after installation and then annually moving forward with no more than 12 months between testing. Those that are operating in high-risk facilities such as hospitals or dust laden atmospheres may need to be tested more frequently. It also declares that if anything is found to be faulty then it must be repaired or replaced immediately.

There are several things that can cause fire damper to fail and because they are hidden away inside ductwork these may not  be found out until they are tested or in the worst-case scenario, in the event of a fire when they fail to work.

The most common reasons for fire damper failure are;

  • Blockages or obstructions from debris, broken parts, wires etc.
  • Poor installation.
  • Rust and corrosion.
  • Spring and component failure.
  • Degradation of seals.
  • Broken, faulty or damaged parts.

Fire damper failure can have disastrous consequences, leading to the spread of smoke and fire throughout the building and into fire safety evacuation corridors which can result in the loss of property or loss of life.

Fire dampers are in almost constant use, making it essential to ensure they close reliably when needed. By providing a barrier that prevents fire from spreading, properly functioning fire dampers save lives.

Fire Damper – Open


Fire Damper – Closed

One of the main challenges in fire damper testing is identifying, locating, and accessing each damper within a building’s ductwork. Without expert knowledge, dampers can easily be overlooked or left unmaintained, compromising the safety system. Even when located, many dampers are hard to reach, making it essential to have access in order to inspect and test the internal blades properly. Thorough testing requires skill, experience, and the right equipment to ensure every damper operates effectively when it’s needed most.

Following the completion of your fire damper testing, we will provide you with a comprehensive written report to confirm compliance with BS 9999:2017. This report serves as an essential record for your fire safety management and should be kept on file.

Your report will include:

  • Before and after photographs of each fire damper
  • Damper numbers and exact locations for full traceability
  • Detailed findings and outcomes of the inspection

This documentation provides clear evidence of compliance and can be presented to a Safety Compliance Officer or relevant authority if required, giving you complete confidence in the fire safety of your building.
