Free CRST Risk Management Principles Questions and Answers — Questions and Answers
Question 1: Which of the following is the first and most effective step in the hierarchy of controls for managing workplace risks?
- Personal Protective Equipment (PPE)
- Administrative Controls
- Elimination (Correct answer)
- Engineering Controls
Correct answer: Elimination
The hierarchy of controls ranks risk control methods from most to least effective. Elimination, which involves physically removing the hazard from the workplace, is the most effective measure because it completely removes the source of potential harm.
Question 2: A manufacturing plant identifies that a solvent used for cleaning machine parts is a volatile organic compound (VOC) that poses a significant inhalation hazard. According to the hierarchy of controls, what is the MOST appropriate initial action to consider?
- Requiring all workers in the area to wear respirators.
- Installing a new ventilation system to capture the fumes.
- Implementing a job rotation schedule to limit exposure time.
- Researching and testing a non-toxic, water-based cleaning agent. (Correct answer)
Correct answer: Researching and testing a non-toxic, water-based cleaning agent.
The most appropriate initial action according to the hierarchy of controls is substitution. Researching a non-toxic alternative directly replaces the hazard with a safer option. This is more effective than engineering controls (ventilation), administrative controls (job rotation), or PPE (respirators).
Question 3: The concept of 'ALARP' (As Low As Reasonably Practicable) is a key principle in risk management. What does it fundamentally require an organization to do?
- Eliminate all risks entirely, regardless of the cost involved.
- Reduce risks until the cost of further reduction is grossly disproportionate to the benefit gained. (Correct answer)
- Meet the minimum legal requirements for safety and nothing more.
- Transfer all significant risks to a third-party insurer.
Correct answer: Reduce risks until the cost of further reduction is grossly disproportionate to the benefit gained.
ALARP requires that risks be reduced to a level that is as low as is reasonably practicable. This means that measures to reduce risk must be taken until the cost (in terms of money, time, or trouble) of taking further measures would be grossly disproportionate to the additional risk reduction benefit achieved.
Question 4: According to Canadian risk management principles, such as those outlined in CSA Z1002, what is the definition of 'risk'?
- Any source of potential damage, harm, or adverse health effects.
- An unsafe act performed by a worker in the workplace.
- The financial cost associated with a workplace incident.
- The combination of the likelihood of harm and the severity of that harm. (Correct answer)
Correct answer: The combination of the likelihood of harm and the severity of that harm.
Standard definitions, such as those in CSA Z1002, define risk as the combination of the likelihood (or probability) of an occurrence of harm and the severity of that harm. A hazard is the potential source of harm.
Question 5: A construction company is conducting a risk assessment for a new high-rise project. Which of the following is a crucial step in ensuring the risk assessment process is effective and inclusive?
- Having the assessment conducted solely by an external consultant.
- Limiting the review of the assessment to senior management only.
- Consulting with workers who will be performing the tasks. (Correct answer)
- Basing the assessment only on incidents from the previous year.
Correct answer: Consulting with workers who will be performing the tasks.
Involving and consulting with workers is a fundamental principle of effective risk management. Workers have direct knowledge of the tasks and associated hazards and can provide valuable input into the identification, assessment, and control of risks.
Question 6: After implementing a new machine guard (an engineering control), what is the final and essential step in the risk management process?
- Documenting the change in the safety manual.
- Training the workers on the new guard.
- Cancelling the company's insurance policy for that machine.
- Monitoring and reviewing the effectiveness of the control. (Correct answer)
Correct answer: Monitoring and reviewing the effectiveness of the control.
Risk management is a continuous cycle. After a control measure is implemented, it is crucial to monitor and review its effectiveness to ensure it is working as intended, has not introduced new hazards, and is being used correctly by workers. This evaluation allows for continuous improvement.
