Smoke and Fire Products

Smoke is the greatest threat to life safety in a fire situation Grpahics 1 and 2 indicate one of the many problems smoke can cause in large buildings. Graphic 1 shows a typical mall with a central atrium. In the event of fire at a lower level, smoke will rise and enter the upper floors. This smoke will reduce visibility and cause occupants to be disorientated and could result in deaths.

By using smoke curtains and smoke ventilators and fresh air intake it is possible to ensure that the unaffected floors are protected.

In graphic 2 the result of installing an automatic smoke control system can be seen.

The smoke detection system would activate and the smoke curtains would be activated on all floors other than the floor on which the fire has been detected. In turn the smoke extraction system would operate leaving the remainder of the building free from smoke thus allowing safe egress for the occupants.

Fire compartmentation is a Building regulations requirement, access routes through fire walls need to be protected to provide the required fire integrity. Installing automatic fire curtains is a cost effective solution . Their application is particularly appropriate in access doors between different sections of a storage warehouse, where installed doors may not provide an adequate fire barrier. Fire curtains are available in various widths.
