Q1. Which of the following best describes the 'moral case' for working safely?
  • A.  Workers and their families should not have to suffer injury, illness or death because of work
  • B.  Insurance premiums fall when accident rates fall
  • C.  Prosecution can be avoided if procedures are followed
  • D.  Shareholders expect a positive safety record
Show answer & explanation
✓ Answer: A. Workers and their families should not have to suffer injury, illness or death because of work
The moral case is about the basic human right not to be harmed by going to work, and the duty employers and workers owe to protect each other and their families from injury or ill health. The other options describe financial or legal drivers, not moral ones.
Q2. Which statement best distinguishes a hazard from a risk?
  • A.  A hazard is always man-made, a risk is always natural
  • B.  A hazard is the source of potential harm; a risk is the likelihood and severity of that harm occurring
  • C.  A hazard only applies to equipment, a risk only applies to people
  • D.  There is no meaningful difference between the two terms
Show answer & explanation
✓ Answer: B. A hazard is the source of potential harm; a risk is the likelihood and severity of that harm occurring
This is the core distinction taught throughout the course: hazard = source of potential harm, risk = likelihood combined with severity of that harm being realised. Confusing the two terms is one of the most common early mistakes learners make.
Q3. A worker is exposed daily to fine silica dust while cutting concrete without respiratory protection. What is the primary long-term hazard?
  • A.  Silicosis and other lung disease from inhaling fine dust
  • B.  Immediate visible burns to the skin
  • C.  Hearing loss from the dust itself
  • D.  Short-term memory loss with no lasting effect
Show answer & explanation
✓ Answer: A. Silicosis and other lung disease from inhaling fine dust
Fine silica dust generated when cutting concrete can be inhaled deep into the lungs, causing silicosis and other serious, often irreversible lung disease over repeated exposure. It does not cause skin burns or hearing loss, and describing any cognitive effect as having 'no lasting effect' misrepresents the seriousness of dust-related lung disease.
