[Accidental explosions in Denmark when working on containers for combustible fluids].

Gases may be formed in containers for inflammable fluids and these may burn explosively if lit. Even apparently empty containers may contain sufficient quantities of gas to result in violent explosions precipitated by procedures which produce heat or sparks in the neighbourhood of the container. Seventeen persons were found to be injured in accidents of this type in a Danish investigation. Two of the accidental injuries proved fatal. The serious risk involved in handling and treating containers which contain or have contained inflammable fluids is, therefore, emphasized.
