White Card (Construction Induction) Practice Test — All Questions
4 questions
In the hierarchy of control, which measure is the most effective way to deal with a hazard?
- a.Putting up a sign
- b.Telling workers to be careful
- c.Wearing PPE
- d.Elimination: removing the hazard completely✓
The hierarchy of control ranks elimination as most effective, followed by substitution, isolation and engineering controls, then administrative controls, with PPE as the least effective, last line of defence.
Where does personal protective equipment (PPE) sit in the hierarchy of control?
- a.It removes the hazard
- b.At the bottom, as the least effective control, used when higher controls cannot fully manage the risk✓
- c.At the top as the best control
- d.It is not part of the hierarchy
PPE is the lowest-ranked control because it only protects the individual and relies on being worn correctly. Higher-order controls that remove or reduce the hazard at source should always be considered first.
What is the correct order of the basic risk-management process?
- a.Review first, then ignore
- b.Assess the risk only if someone is hurt
- c.Control the risk, then look for hazards
- d.Identify the hazard, assess the risk, control the risk, then review the controls✓
The process is: identify hazards, assess the risks they pose, control the risks using the hierarchy of control, and then review the controls to make sure they are working. Reviewing keeps controls effective as work changes.
A 'hazard' on a construction site is best described as:
- a.A worker who is careless
- b.Only things that have already caused an injury
- c.The paperwork for a job
- d.Anything with the potential to cause harm, injury or illness✓
A hazard is any source or situation with the potential to cause harm, such as working at height, electricity, moving plant or dust. The 'risk' is the likelihood and severity of harm actually occurring from that hazard.
