Operation Comet - Hatfield Tunnel RTA (road traffic accident) - Case Study
Courtesy of Concept Smoke Systems | Concept Engineering Ltd.
A staged multi-vehicle accident in the Hatfield Tunnel, involving a road tanker, 2 lorries and a minibus took place in October 2011. Concept's ViCount smoke system produces the world's most persistent artificial smoke, critical when you are looking at smoke travel over several kilometres.
The operation was designed to test the responses of the emergency services and the tunnel video smoke detection and ventilation systems.
Three ViCount systems were used to smoke log the entire tunnel section. The tunnel video smoke detection system rapidly detected the initial smoke production and the tunnel operator then contacted the various emergency services and instigated the tunnel ventilation plan associated with such as incident.
Smoke was produced continuously for 2 hours for this multi-agency emergency exercise. A senior member of the exercise team concluded 'A very impressive simulation!'
