Answer to Question 2
Answer: The process is basically one of recognition, evaluation, and control. First, the facility's health and safety officers must recognize possible exposure hazards. Doing so typically involves conducting plant/facility walk-around surveys, employee interviews, records reviews, and reviews of government and nongovernmental standards regarding various occupational exposure hazards. Then, the evaluation phase involves determining how severe the hazard is. This usually requires measuring the exposure, comparing the measured exposure to some benchmark and determining whether the risk is acceptable. Finally, the control phase involves taking steps to eliminate or reduce the hazard so that it no longer ranks as dangerous.
