Free CRST Risk Management Principles 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?

Accepted Answer

Elimination

Answer

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?

Accepted Answer

Researching and testing a non-toxic, water-based cleaning agent.

Answer

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?

Accepted Answer

Reduce risks until the cost of further reduction is grossly disproportionate to the benefit gained.

Answer

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'?

Accepted Answer

The combination of the likelihood of harm and the severity of that harm.

Answer

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?

Accepted Answer

Consulting with workers who will be performing the tasks.

Answer

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.
