A huge amount of work goes in to keeping people safe from fires. That includes performing fire damper tests in any property that features them. We happen to be excellent providers of this essential service. The Trident team performs an array of inspections here, including drop tests. After a test we give you a report on the state of all your dampers.

Fire dampers are vital for safeguarding people and assets. They stop the spread of fires through different areas of a property. For example, you can place them in air conditioning, ventilation, and heating ducting. The Building Research Establishment (BRE) states that all ductwork going through compartment and sub-compartment walls needs the dampers. This is to ensure fires can’t spread quickly through these service ducts.

How do dampers work?

They function by closing automatically once they detect heat. Usually, a thermal element shall melt after you reach a specific temperature. Normally, this will be 165ºF (around 73ºC). What this does is enable the damper to close. It stops the fire going further down the duct.

Things can get more complicated here though, because there are multiple fire damper types. As you would expect, they work in different ways.

Static dampers

Fire damper testsOne type is the static damper. Once these detect a fire, they will cut the air flow off through your ducting. They do so by shutting the HVAC system down automatically.

The most common static variant is a curtain damper. A folded ‘curtain’ is held up at the top of the ducting via a fusible link/thermal element. When the temperature reaches a specific point, this melts. The damper then falls shut thanks to gravity.

Multiple-blade dampers also belong to the static damper family. They have blades positioned in the airstream. When released, they pivot. These block the air flow present in the duct more than a curtain damper does.

Dynamic Dampers

There are also dynamic fire dampeners. They are the best choice when a HVAC system shall carry on working when there is a fire. You would install them in vertical barriers and they shut using a spring-loaded mechanism. Said mechanism has sufficient power to endure the air pressure. Speak to us if you are in need of fire damper tests.

Smoke dampers

These devices can halt the smoke spread through the floors and walls of a building. Similar to fire dampers, you place them in the ductwork. The difference is you put them in locations where smoke penetration would be a major issue. You control the dampers through a smoke detection system.

These products close automatically as well, just like the static and dynamic models. However, you don’t install them with sleeves; instead they fit directly into the duct. Your closure mechanism here shall either be a spring or pneumatic actuator.

We know the significance of fire damper tests

At Trident Fire Protection and Training, we understand how important fire dampers are. But, they are often out of sight, leading to people forgetting about them entirely. Sadly that leaves a risk that they won’t work when you need them the most. Luckily, we will make sure that everything is up to standard with professional testing. This way, you will be in a far better position to handle a fire should you have one.

So, please let us know if you would like some help with fire damper tests. We offer services all over the UK, catering for almost any type of building.
