Maintenance and risks from respirable crystalline silica dust

The video shows dust exposure levels of workers maintaining, servicing and repairing plants and equipment, which may generate airborne respirable crystalline silica dust. It compares the exposure levels with and without respiratory protective equipment (with an appropriate protection factor) and shows  the dust concentration in breathing air is significantly reduced. The video shows the dust formation and as a concentration curve from a parallell dust measurement. 
The video is available in several EU languages; access via selecting the proper language in the language menue and klick on "implementation / videos".
