Distinguishing dust types
Health hazardous dust types develop during sanding that can provoke coughing, asthma or bronchitis. Only high quality industrial vacuum cleaners are reliable enough to efficiently remove such dust. Following the international EC 60 335-2-69 norm, dust is classified into three different types: L, M and H. The Employers Liability Insurance Association will inform you about which dust type can develop at your specific work place. Dust types are distinguished using so called MAK values that assign the maximum legal concentration at a workplace (in mg/m³) that does not lead to health problems even in case of long term exposure. The lower the MAK value, the more dangerous the dust type.
Dust Class L
Nonhazardous dust types such as sand, cement, earth or pebble stone
Dust Class M
Mineral dust types as well as birch, beech, oak and fir wood dust
Dust Class H
Health hazardous dust types such as asbestos, mineral fibers, glass wool, mould or minerals containing silica
