Safe4 ® Smoke Extract Ductwork

Smoke is recognised as the major killer during fire outbreaks. It can spread quickly to nearby buildings that are quite remote from the original blaze, threatening life and damaging property. Stairwells and elevator shafts frequently become smoke logged, blocking evacuation routes and preventing firefighters and other rescue teams from doing their critical jobs. Safe4 ® Smoke Extract ductwork is a key component of a fire strategy, by safely funnelling smoke out of a building.

Insulation is a factor preventing flashover

Exhausting smoke from a fire creates a potential flashover risk in compartments other than the fire compartment. As part of the EN tests, insulation can help prevent flashover.

Fire-rated insulation ensures that the temperature measured, outside in Type A and inside in Type B, does not exceed 140ºC mean average above ambient during the test, and is deemed automatically failed if any thermocouple rises to 180ºC.

The inclusion of insulation during fire testing means that the system becomes the product. Use of untested combinations of duct and insulation is not permitted without completing a full test programme.
