Were there any munition factory explosions in London, just like in WW1?

During WW1 there were many factory accidents in London. For instance the Silvertown factory that caused more destruction than all german air raids combined. But what about WW2?
Did munition manufacturing improve significantly between the two wars when it comes to safety?
Are these explosions not talked about as much as the ones in WW1 because of the destruction of the blitz?
