Let’s be honest: Occupational Health and Safety (OHS) is often treated as the “dry” part of a professional degree. People think it’s just a collection of posters about wet floors and yellow hard hats. But when you’re staring down a 50-mark exam paper, you quickly realize that OHS is a complex web of legal liability, engineering controls, and human psychology.

The difference between a student who “knows” safety and a student who “passes” safety is the ability to apply the Hierarchy of Controls under pressure. You don’t want the first time you see a complex industrial accident scenario to be during your final exam. That is why we’ve curated a massive library of OHS Past Papers for you to download and use as your secret weapon.
Check out these common Q&As that frequently appear in recent certification and degree exams.
OHS Q&A: The Revision High-Yield List
1. What is the “Hierarchy of Controls,” and why is PPE the last resort?
This is the most common question in OHS history. Examiners want to see if you understand that fixing the environment is better than fixing the person.
-
Elimination/Substitution: Removing the hazard or replacing it with something safer (e.g., using a non-toxic solvent).
-
Engineering Controls: Isolating the hazard (e.g., a machine guard).
-
Administrative Controls: Changing how people work (e.g., training or signage).
-
PPE: The “Last Resort.” It only works if the worker wears it correctly every single time. It doesn’t remove the danger; it just places a small barrier between the danger and the human.
2. How do you distinguish between a “Hazard” and a “Risk”?
Many students use these interchangeably and lose marks for it.
-
Hazard: Anything with the potential to cause harm (e.g., a frayed electrical wire).
-
Risk: The likelihood that the hazard will cause harm, combined with the severity of that harm (e.g., the risk is high if that wire is in a wet area where people walk barefoot).
3. What is “Incident Root Cause Analysis” (RCA)?
If an accident happens, an OHS officer doesn’t just ask “who did it?” They ask “why did it happen?” In an exam, if you are asked to perform an RCA, use the “5 Whys” technique. Keep asking “why” until you hit the systemic failure—usually a lack of training, poor maintenance, or a flawed safety culture—rather than just blaming human error.
4. Can you explain the difference between Acute and Chronic health effects?
-
Acute: Immediate effects from a high-level, short-term exposure (e.g., a chemical burn or a fall).
-
Chronic: Long-term effects from low-level, repetitive exposure (e.g., hearing loss from loud machinery over 10 years or silicosis from inhaling dust).
Why Downloading Past Papers is Your Best Bet
Safety isn’t just about common sense; it’s about legal standards and technical accuracy. By using our downloadable past papers, you will:
-
Learn the “Action Verbs”: Notice how examiners ask you to “Evaluate,” “Design,” or “Justify.” Each requires a different depth of answer.
-
Master the Risk Matrix: Practice plotting hazards on a $5 \times 5$ risk matrix until you can do it with your eyes closed.
-
Understand Legislation: OHS is heavily tied to the law (like OSHA or HSE standards). Past papers show you which specific regulations you need to cite to get those extra “distinction” marks.
