Tuesday, December 19, 2017 Cancer–Causers in the Construction Sector Newsletters A new report shows that many Ontario workers—particularly those in construction—are exposed to cancer-causing agents in their workplaces. Cancer is the leading cause of death in Ontario, and two to ten percent of all cancers can be traced to occupational exposure. The main hazards are solar UV radiation, asbestos, diesel engine exhaust, and silica. 450,000 workers (mainly in construction and agriculture) are exposed to solar UV rays each year, leading to 1,400 nonmelanoma skin cancer cases per year. 301,000 workers (primarily in mining and transportation/warehousing) are exposed to diesel engine exhaust, leading to 170 cases of lung cancer and 45 cases of bladder cancer per year. 142,000 workers (mainly in construction, manufacturing, and mining) are exposed to silica dust, leading to 200 cases of lung cancer per year. 55,000 workers (primarily in construction) are exposed to asbestos each year, leading to 630 cases of lung cancer, 140 cases of mesotheliomas, 15 cases of laryngeal cancer, and up to 5 cases of ovarian cancer per year. The report recommends the government “strengthen occupational exposure limits so they are up to date, rigorous, and based on evidence of health effects; reduce or eliminate the use of toxic substances; create registries of worker exposure to occupational carcinogens to facilitate the tracking of exposures; and broadening current occupational health and safety legislation to better protect workers in the construction industry.” As a worker, remember to follow the health and safety procedures in place, and always wear proper PPE. If you have concerns, bring them to your health and safety rep and if they are not addressed, to the union. Remember, you have the right to refuse unsafe work.
