Abschnitt 1.2 – 1.2 Dust

If large quantities of magnesium dusts are generated during machining (e. g. during grinding), fire and, in addition, a dust explosion have to be expected. A fire develops if accumulated dust ignites. Even if low quantities of whirled up dusts ignite, an explosion hazard is caused. Particles with a mean diameter of < 500 µm are referred to as dust. These particles are considered to be explosive when being whirled up.

The dust particles constitute a large surface. Even a reaction with the water in the humid air may release such an amount of hydrogen that an explosive mixture develops.

If work clothes are soiled by magnesium dust or magnesium chips, employees are exposed to an increased fire hazard.
