Saying this, Dipak M Bhadra of Leminar suggests that system should comply with stability, integrity and insulation resistance against the fire
One of the critical challenges to maintain fire safety in buildings is to protect the HVAC equipment from causing fires, said Dipak M Bhadra, General Manager, Leminar Air Conditioning Industries.
Highlighting some recommended solutions, Bhadra said: “From an HVAC perspective, the building must be equipped with certified and test fire-rated duct systems, including a smoke extractor, staircase pressurisation system and a lobby-extract system.
“This system should comply with stability, integrity and insulation resistance against the fire, and it should be tested as per the BS-476: Part 24 standard set by manufacturers. Additionally, manufacturers must have a valid third-party certification.”
Bhadra added that the installation contractor must strictly comply with all the guidelines specified for the installation of the fire-rated duct. Other practices would include the use of non-toxic and fire-safe insulation materials over the ducts to protect occupants from the generation of toxic smoke as well as prevention of the spread of fire from insulation material.
