Control the ventilation of smoke
Inhalation of toxic fumes and smoke kills 90% of all fire victims and not the actual fire. Acrid smoke can fill the lungs before the flames have even manifested or reached their victim. Smoke ingress can happen in minutes, preventing escape, so as part of your fire risk assessment and evacuation plan, consider that dealing with the removal of the smoke will improve the conditions and chances of survival of its occupants, aiding in a successful evacuation or rescue.
Most commonly used escape routes are corridors, stairwells and lobbies, so mechanical ventilation systems – roof, window vents or skylights, are strategically placed to extract smoke from these areas by automatically opening when detectors or call points are actuated. Ventilating and assisting with the removal of the smoke as quickly as possible.
