Workplace accidents explosions can cause significant injuries and long-term damage, therefore reducing the risk of occurrence by using properly positioned signage is highly advised.

Explosive atmospheres can be caused by flammable gases, mists, vapours or combustible dusts. Highlighting areas where such elements are produced can help stop accidental ignition.

Compressed gas is also an explosive risk, if a container is damaged or starts leaking, a small ignition source can trigger an individual explosion or multiple explosions if containers are stored in close proximity.
