The following information is for general guidance only:

Dusts are created when solid materials are broken down into fine particles.

The smaller the dust, the greater the hazard.

Mists are tiny droplets that are formed from liquid materials by atomisation and condensation processes such as spraying.

Fumes are created when solid materials are vaporised under high heat. The vapour is cooled quickly and condenses into extremely fine particles.

Dusts, mists and fumes are filtered out using a sieve.

P3 SL or FFP3 SL D

As FFP3 S but with additional protection against all kinds of liquid aerosols

  

Gases and vapours consist of molecules, which are so small that they penetrate a particulate filter. In these cases a chemical filter should be used.

Gases and vapours are filtered out using sponge.
