3M Health Safety Helpline FAQ's

The health effects of long term exposure to respirable crystalline silica are well documented and include silicosis, chronic obstructive pulmonary disorder (COPD) and lung cancer. The level of risk depends on the amount of exposure which is determined mainly by the materials and work methods used, the duration of the work and the controls in place. Get price

Respirable Crystalline Silica Exposure

Crystalline silica particles with a diameter less than 10 μm are considered respirable, posing the most potential danger to employees. The extended inhalation of respirable silica particles can lead to these particles becoming embedded in lung tissue, significantly increasing the risk that workers develop silicosis, lung cancer, chronic obstructive pulmonary disease (COPD), and/or renal disease.
