Blast engineering company Aigis has developed a bin which, it claims, will completely contain a bomb blast indoors in busy places such as airports and stations.
The new bin incorporates existing technology already in use in bomb-proof bins - a cylinder made from wound glass fibre but adds two new components. The first is a blast reduction substance called Tabre which is made from tiny stones coated with silicone and compressed into a solid lining. The second component is a water-air suppression system that goes into the lid of the bin.
The key to making the bin blast-safe is to absorb all the energy an explosion creates. The bin's Tabre lining disintegrates, soaking up the energy of the blast so that the glass fibre cylinder can do its job and prevent the explosion bursting sideways.
The blast energy sent upwards is caught by the water-air suppression system in the lid. The water in the mixture turns to steam using up the remaining energy of the blast and containing its energy.
