The large amount of smoke and heat that is quickly generated during a fire can make it difficult for people to locate and reach escape routes: adequate ventilation to remove the smoke and heat quickly is essential.

Smoke and heat exhaust ventilation systems address this need by directing hot smoke away from exit routes, allowing it to be identified and then evacuated, providing safe access for rescuers.

Smoke and Heat Exhaust Ventilators (SHEV) are openings in the roof of rooms which, as they are suitably positioned and distributed, allow the masses of hot gases that tend to move upwards to be expelled outside.

The removal of heat helps to delay or avoid a flash over and to reduce any damage caused by combustion gases or any toxic and corrosive substances generated by the fire.

In order to ensure their effectiveness, it is essential that the checks required by the standards, which detail all the activities and maintenance schedules, be performed by specialised personnel.
