Dust/Chip Extraction

f 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

connection with wood-treatment additives

(chromate, wood preservative). Materials

containing asbestos may only be worked by

specialists.

– Provide for good ventilation of the work-

ing place.

– It is recommended to wear a P2 filter-

class respirator.

Observe the relevant regulations in your

country for the materials to be worked.

f Prevent dust accumulation at the work-

place. Dusts can easily ignite.
