Silica, or crystalline silica, is a mineral that is found in many construction materials such as sand, cement, gravel, stone, brick and mortar. Over-exposure to silica can cause coughing, breathing difficulties, wheezing, eye irritation, lung cancer, or silicosis. In order to avoid these, employers have a duty to train employees on tasks that may expose them to these hazards. These tasks may include cutting bricks with a handheld power saw, cutting concrete blocks with a stationary masonry saw, or grinding mortar. 

Because of these hazards, T. Harris Environmental Management is inviting you to a complimentary webinar to be held on November 15th. This webinar will discuss: 

• history of silica 
• what silica is 
• common uses for silica in the workplace 
• guidelines for protecting the worker against silica

Learn from our expert Occupational Hygienist, Richard Quenneville, about the newest workplace hazard during our complimentary webinar.
