Researchers at the University of Warwick and Coventry-based company Carboline Nullfire have developed a container to protect gas cylinders from explosion and venting gas when over-heated.
Gas-Safe is claimed to be capable of protecting a cylinder at 1,000 degrees C for over 30 minutes.
The problem was to insulate the cylinder against the heat of a fire without cooling it so much that it would fail to operate under normal conditions.
In the Gas-Safe, vents allow air to circulate around the cylinder to keep it warm enough under normal conditions.
In a fire, specially developed intumescent material swells up and seals the vents, while insulation keeps the temperature in the bottle below 60 degrees C.
