Standards for fine dust respiratory protection
For solid hazardous, fibrogenic particles
(fine dust up to 4 x MAK - Maximum Workplace Concentration) e.g.: textile fibres, marble, sulphur, silicic acid
For solid and gaseous, less-toxic particles
(fine dust up to 10x MAK) e.g.: carbon, copper, aluminium, cotton, metal, textile fibres, manganese, welding fumes
For solid toxic particles
(to avoid levels being exceeded, filters of this level must be used up to 30 x MAK value) i.e.: chromium, nickel, lead
