FFP1
Protection from atoxic and non-fibrogenic kinds of
dust
Protection class FFP1 respirator masks are made for working environments
in which neither poisonous nor fibrogenic kinds of dust and aerosols are to be
expected.
They filter at least 80 % of the particles measuring up to 0.6 μm
and may be worn as long as the maximum workplace concentration transgression
measures no more than the fourfold value.
The building or food industry put
FFP1 respirator masks to use in many cases.
FFP2
Protection from firm and fluid harmful kinds of dust, smoke, and aerosols
Particles may be fibrogenic – which means they irritate the respiratory system
in the short term and can result in reduction of elasticity of pulmonary tissue
in the long run
Protection class FFP2 respirator masks are made for working
environments in which deleterious and mutagenic particles can be found in the
breathing air.
Respirator masks of this class must contain at least 94 % of
the particles measuring up to 0.6 μm and may be used in environments
transgressing the OEL up to a maximum of the tenfold concentration.
Protection class FFP2 respirator masks are often worn in the metal and mining
industry. Workers in these industries are frequently in contact with aerosols,
fog and smoke that result in conditions of the respiratory system such as lung
cancer in the long term.
FFP3
Protection from
poisonous and harmful kinds of dust, smoke, and aerosols
Oncogenic and
radioactive substances or pathogens such as viruses, bacteria and fungal spores
are filtered by this protective class of respirator masks
Protection class
FFP3 respirator masks offer maximum protection from breathing air pollution.
Respirator masks of this class must filter 99% of all particles measuring up to
0.6 μm.
This kind of mask also filters poisonous, oncogenic and radioactive
particles.
Protection class FFP3 masks are often used in the chemistry
industry.
