Dust/Chip Extraction

Dusts from materials such as lead-containing coatings, some
wood types, minerals and metal can be harmful to one's
health. Touching or breathing-in the dusts can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dusts, such as oak or beech dust, are considered as
carcinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials contain-
ing asbestos may only be worked by specialists.
– Always use dust extraction.
– Provide for good ventilation of the working place.
