Smoke inhalation kills more people than the fire itself, so our emphasis is on smoke clearance in the event of a fire incident. Mechanical smoke ventilation systems provide a controlled alternative method to natural smoke ventilation. Mechanical smoke ventilation systems offer the ultimate in smoke control allowing occupants to escape and providing clear access for fire fighting services.
Comprehensive smoke ventilation systems
Marshall Electrical Services provide comprehensive ventilation systems comprising a mechanical extract shaft serving the common corridor and/or lobby. Replacement air is generally provided from the stairs by means of a pressure controlled door closer. This de-pressurises the stairs, allowing a large quantity of fresh air to be pulled through the lobby meaning smoke cannot flow into the stairs.
When smoke is detected in a lobby or area, only the fire damper to the shaft on the fire floor will open and the vent at the head of the staircase opens. The fan at the top of the stairs extracts the smoke and prevents migration of smoke into the adjacent compartments. This sequence is automatically controlled from a signal raised from the fire system. The operation allows sufficient time to clear smoke away from the escape route and after evacuation closes down to help eliminates the fire.
Factors influencing your preferred commercial smoke ventilation system
Every building is different and a range of internal and external factors will influence which is the best solution.
