Expertise in the construction business: dust & protective ventilation

For construction machines, the professional organisation (BG) prescribes an additional external fine filtration for applications with exposure to loads (e.g. work in closed shops, work with hazardous substances, etc.).


 
The target group is described as follows (BGI 581):

"If earth-moving machines and special underground engineering machines are used in contaminated areas, the machine operators must be protected against inhaling hazardous substances. Earth-moving machines are e.g. excavators, loaders, graders and scrapers.“

According to DIN ISO 6165, special underground machines are e.g. excavators as carrier devices, which are equipped with pile-driving and drilling equipment. Work in contaminated areas is described in the professional organisation rule "Contaminated areas" (BGR 128).
