Fire exhaust fan set Location: Distance tunnel fire exhaust fan should not be too close to the side wall, so as not to affect the ventilation exhaust fan fire tunnel wall arranged for a minimum distance from 20 cm, rescue "sentinel" setting will tunnel into. Disaster different regions, make full use of deviated and both ends of the tunnel exhaust fan fire rescue station designated as the wind and smoke into the new channel, cross ventilation openings must maintain positive pressure state exhaust fan to prevent flue gas flow the channel. ventilation system to air, flue gas into a cross-channel and suppress the accident did not occur in the tunnel exhaust fan fire models to meet evacuees facing the new cross-channel air into the tunnel from the security and safety of the tunnel through the cross-channel tunnel direction to accident while ensuring the required waiting area with fresh air. According to different regions within the tunnel accident Disaster different ventilation mode. When the "sentinel" Disaster ventilation scheme implemented when the train rescue point in the "sentinel" range for all contacts Cross channel settings can be inverted to obtain a fresh wind from the fan inside the secure tunnel.
