Occupational Health and Safety
Exam Answer Key
Course Introduction
Occupational Health and Safety is a comprehensive course that introduces students to the principles, practices, and regulatory frameworks designed to promote safety and well-being in the workplace. The course covers hazard recognition, risk assessment, and control strategies to prevent workplace injuries, illnesses, and accidents. Students will explore topics such as safety management systems, emergency preparedness, ergonomics, workplace hygiene, and legal responsibilities of employers and employees. Through case studies and practical examples, participants will learn how to implement effective safety programs and foster a culture of health and safety in various occupational settings.

Sample Questions
Q1) Can a risk of fatality ever be considered "moderate?" Explain your reasoning.
Answer: Yes,thousands of people every day risk fatality hazards because the probability of occurrence is extremely low.Air transportation is a good example.The Risk Assessment Code (RAC)used by the U.S.Air Force rates a hazard as "code 3 - moderate" even if the severity is category 1 - "death or permanent disability,resource loss or fire damage more than $1,000,000" PROVIDED that the mishap probability is rated category D - "unlikely to occur."
Q2) What two elements are conspicuous in their absence from the Hazards Classification Scale as set forth in the text?
Answer: Cost of abatement of the hazard OSHA legal definitions of hazard seriousness
Q3) Explain why the enforcement approach is difficult to apply to the problem of controlling hazards.
Answer: To be enforceable,enforcement rules must be applied in absolutes such as "always do this," or "never do that," but mandatory language using the terms "always" or "never" are inappropriate in dealing with the uncertainties of safety and health hazards.
Q4) Name the four principal approaches to hazard control and avoidance. Answer: enforcement,psychological,engineering,analytical
