Developed by OHCOW, this calculator is a powerful risk communication tool. It allows workers to assess their own risk of getting lung cancer based on their job, level of exposure to diesel fume, and how long they have been exposed. If the level of risk is clearly communicated, then this should motivate reducing exposures through actions of workers, unions, employers and the Government. It also provides a mechanism through decision makers set "health based" occupational exposure limits by following the science.
Make 20 the limit.
