FREE Certified Industrial Hygienist Occupational Health Hazards Questions and Answers

Question 1

All of the following tactics—with the exception of—are used to control occupational health hazards:

Accepted Answer

Inspections and audits

Answer

The hierarchy of controls outlines the primary strategies for managing occupational health hazards: elimination/substitution, engineering controls, administrative controls, and personal protective equipment. Inspections and audits are essential tools for identifying hazards, monitoring compliance, and evaluating the effectiveness of controls, but they are not direct control *tactics* themselves in the same way the other options are.

Question 2

Which of the following methods for reducing or eliminating workplace health risks is most effective?

Accepted Answer

Engineering controls

Answer

Engineering controls are considered the most effective method in the hierarchy of controls because they eliminate or reduce the hazard at its source, often through physical changes to the workplace or process. This approach provides the highest level of protection as it does not rely on worker behavior or continuous management, unlike administrative controls or PPE.

Question 3

Which of the following approaches is regarded as the first line of defense for limiting workplace health risks?

Accepted Answer

Engineering controls

Answer

Engineering controls are positioned high in the hierarchy of controls, often considered the first line of defense after elimination/substitution. They aim to reduce or remove hazards by modifying the work environment or process itself, thereby making the workplace inherently safer. This proactive approach is preferred over relying on administrative procedures or personal protective equipment.

Question 4

Which approach might be required if it is not possible to make the workplace entirely safe?

Accepted Answer

Personal Protective Equipment

Answer

When engineering and administrative controls are not feasible or cannot fully eliminate a hazard, Personal Protective Equipment (PPE) serves as the last line of defense. PPE protects the individual worker from residual hazards that cannot be controlled by other means, acting as a barrier between the worker and the hazard.

Question 5

What discipline of science investigates a substance's toxicity or poisonousness?

Accepted Answer

Toxicology

Answer

Toxicology is the scientific discipline dedicated to studying the adverse effects of chemical, physical, or biological agents on living organisms. This includes investigating a substance's toxicity or poisonousness, dose-response relationships, and mechanisms of action. The other disciplines listed focus on drug action, viruses, or disease patterns in populations.
