An impact analysis of two silica dust exposure reduction strategies

Crystalline silica dust exposure is common in the construction sector. Inhalation of silica dust is known to cause lung cancer, silicosis, chronic obstructive pulmonary diseases, rheumatoid arthritis and tuberculosis. In this presentation, Dr. Emile Tompa examines the implementation of two approaches to reducing exposure: use of personal protective equipment (i.e. respirators) by all exposed individuals and use of engineering controls (e.g. wet method) wherever and whenever feasible. He shares findings from an impact analysis based on data spanning 30 years.
