Dust/Chip Extraction

Dusts from materials such as lead-containing
coatings, some wood types, minerals and
metal can be harmful to one's health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in con-
nection with wood-treatment additives (chro-
mate, wood preservative). Materials contain-
ing asbestos may only be worked by
specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the working
place.
– It is recommended to wear a P2 filter-class
respirator.
Observe the relevant regulations in your coun-
try for the materials to be worked.
