The risk assessment process involves several steps that aim to identify potential hazards, assess the risks associated with those hazards, implement control measures to reduce the risks, and review existing control measures to ensure they are effective. The steps involved in the risk assessment process are as …
Silicosis among gold miners: exposure--response analyses and risk
Results: The risk of silicosis was less than 1% with a cumulative exposure under 0.5 mg/m3-years, increasing to 68% to 84% for the highest cumulative exposure category of more than 4 mg/m3-years. Cumulative exposure was the best predictor of disease, followed by duration of exposure and average exposure. After adjustment for competing risks of ...
