  There have been many hundreds of accidental explosions within the Industry – just look at things like Buncefield, or Mexico City (https://www.youtube.com/watch?v=o9i7cM7FtfU). We tend to work at levels of up to 1 tonne of TNT Equivalent for Test Rigs, but explosions like Buncefield are of the order of 30 tonnes of TNT Equivalent.
