Designed to prevent the spread of fire.

Fire dampers are located within ventilation systems and they are designed to prevent the spread of fire inside the systems. As such, it’s important to make fire damper testing part of a building’s overall fire prevention strategy and factor it into your maintenance regime.

When functioning as they should, these fire damper installations should effectively prevent the spread of fire and smoke throughout a building by closing when heat is detected. Therefore, it is crucial to check that the actual detection system and mechanism in place are working, so that they are ready to activate should a fire break out.

Fire damper testing requirements

In accordance with British Standards 9999:2017 Annex W.1, all fire dampers should be tested, cleaned and maintained at regular intervals, not exceeding 2 years, whilst spring operated fire dampers should be tested at least once a year. This is because general usage of a ventilation system can create gradual contamination of the fire damper mechanism, which must be removed using the correct fire damper testing tools and procedures.

You may also want to increase your fire damper testing frequency to keep them in good working order all year round and in line with the current legal requirements.Β J&I can help you do this by scheduling regular maintenance checks and performing our industry-standard fire damper testing.

Consequences Of Poorly Maintained Fire Dampers

If a building is your responsibility, remember that the consequences of faulty fire dampers could be serious. In the event that there is a fire, these devices can save lives by preventing the unnecessary spread of smoke and fire to other parts of the building, giving people enough time to evacuate and the fire department a better chance of containing the blaze.

If someone in the building was to actually die as a result of a fire that could have been controlled with operational fire dampers, you could be liable for prosecution under the Corporate Manslaughter Act.

You would also find it harder to claim for fire damage on your insurance unless you can provide reports which prove you have had your fire dampers tested and maintained.

The cleaning service was swift and spotless. Our landlord was very pleased with the conditions. Booking was easy and service was customised. J&I offered a site visit/video viewing to give a reasonable quote.

Found J&I through a Google search. They were very responsive to my questions and easy to book with. The cleaner they sent did an amazing job on the bathroom deep clean, even managed to remove stains I thought were permanent. She was very professional and extremely polite. Brought all their own supplies and even a step ladder to reach the ceiling. I would totally recommend J&I for deep cleaning.

They did a fantastic job for end of tenancy clean. The inspector was impressed and, so far, not had an extra charges from the letting agency. They arrived bang on time and the communication with the office (i had to change the original booking) was excellent. The price was very competitive compared to online search results. Would especially recommend if you live in Quintain flat.

I had a deep clean done on Friday and OMG! What a wonderful experience. She did such a marvellous job. She literally cleaned from head to toe including inside my bathroom cabinet and sink vanity drawers. I would absolutely use this company again and am absolutely happy to recommend to others.

J&I Cleaning were recommended to us by a friend, work from a High Street office, gave me a reasonable quote over the 'phone. They require full payment in advance (!) but... recommended and office based, so... Their worker turned up promptly, got on with the work, moved furniture carefully and appropriately put it back and did a very good job, all within less time than had been predicted. We think money will spent

The cleaners did an excellent job on my kitchen. I had alot of things and so they ran out of time, but I recommend them to others, for they work so well and to a very high standard. I especially love the cooker and microwaves. I would use them again.

Faqs

Fire damper testing is the process of inspecting and testing fire dampers within a building’s ventilation system. These dampers are designed to close in the event of a fire, preventing the spread of flames and smoke through ductwork. Regular testing ensures that fire dampers are functioning correctly and helps maintain the safety of the building’s occupants.

According to British Standard BS 9999:2017, fire dampers should be tested at least every 12 months, or more frequently in some circumstances, such as in environments with high levels of dust or debris. Regular testing helps ensure that fire dampers are functioning correctly and comply with regulatory requirements.

During fire damper testing, our technicians will visually inspect the fire damper assembly for any signs of damage or wear, as well as ensure that the damper is correctly installed and accessible. The damper’s operation will be tested, and any obstructions in the ductwork will be removed. Finally, the damper will be reset to its normal open position, and a test report will be provided with photographic evidence.

Yes, our technicians are certified and experienced in fire damper testing, ensuring compliance with relevant British Standards and industry best practices. We are committed to providing reliable, professional, and efficient testing services to maintain the safety of your building.
