Road tunnels

Nobel Fire Systems has refurbished the fire protection system for two major road tunnels managed by the Highways Agency. The tunnels near Brighton and Folkestone are fitted with extensive lighting and have ventilation fans to ensure adequate levels of air quality. Controls for these lights and fans are situated in close proximity to both the tunnels in purpose built Tunnel Support Buildings, known as TSB's.

The controls are protected by multiple, large Carbon Dioxide gas systems designed to suppress flames in the event of a fire breaking out.

Nobel carried out Hydrostatic tests on the 46 CO2 gas cylinders as part of the manufacturer's 10 year check.

Nobel replaced 10 year old cylinders with either new or refurbished ones and refurbished the seven individual systems within the two tunnels.
