Internal Fire Dampers

Fire dampers are lifesaving pieces of passive fire protection equipment and act as a vital component of a buildings fire safety strategy. They are designed to help to confine a fire to one area of a building, allowing for occupants to evacuate safely and in an orderly fashion giving fire fighters the best chance to deal with the fire before it spreads and causes a high level of damage.

By having fire dampers strategically placed within a building’s air ventilation ductwork system, where it passes through fire compartment walls and floors, the spread of fire can be restricted effectively, the risk to safety reduced and the level of fire damage limited. 

It is important to emphasise that these internal fire dampers will need to be tested regularly and professionally to ensure that:

  • There is no damage or obstruction to them
  • The dampers are operating and closing fully
  • They have been fitted correctly

Fire dampers should be positioned strategically and installed correctly within a building and tested at least once a year. This will make sure they are functioning effectively and are capable of helping to keep the occupants of a building safe when a fire breaks out. This responsibility falls upon the responsible person in charge of the fire safety within the premises of any given business.

This responsibility can frequently feel overwhelming and have complex issues that need to be considered, so those appointed to deal with this aspect of health & safety may require the assistance of a professional passive fire protection company. Here at EA-RS Passive Fire Protection our highly skilled engineers will carry out an annual maintenance check of your internal fire dampers in accordance with BS 9999: 2017 for full peace of mind.
