Explosion hazard

An explosion hazard is a hazard that can occur when an explosive mixture is present at the same time as an ignition source. The explosive mixture may be formed from flammable gases, vapours, mists or dusts. In the interest of occupational safety, Directive 99/92/EC (ATEX 137) stipulates the procedure for dealing with explosion hazards. In Germany, ATEX 137 is embodied in the country's Occupational Safety and Health Act
