Explosion-protected LED flashlights
The European ATEX standard certifies explosion-protected flashlights. The level of danger from dust, fumes or gases is divided into three categories, although not all explosion-protected flashlights are suitable for use in all situations. Explosion-protected LED flashlights are used by firefighters, the military, and in industry.
