Free CRST Risk Management and Assessment Techniques Questions and Answers

Question 1

In the field of occupational health and safety, 'risk' is best defined as:

Accepted Answer

The combination of the likelihood of an occurrence and the severity of its consequences.

Answer

Risk is a measure that combines two critical elements: the likelihood (or probability) that a hazardous event will occur, and the severity of the consequences (e.g., injury, illness) if it does. A hazard is simply the potential to cause harm, but risk quantifies that potential. This calculation is fundamental to prioritizing safety efforts.

Question 2

According to the Hierarchy of Controls, which of the following actions is considered the most effective?

Accepted Answer

Physically removing the hazard from the process.

Answer

The Hierarchy of Controls ranks methods of controlling hazards from most to least effective. Elimination, which involves physically removing the hazard from the workplace, is the most effective control because it completely removes any chance of exposure. All other controls, such as PPE or administrative changes, only reduce exposure rather than removing the hazard itself.

Question 3

A Job Hazard Analysis (JHA) is a systematic process that involves which three key steps?

Accepted Answer

Break the job into steps, identify hazards, and determine control measures.

Answer

The core methodology of a JHA (or JSA) is to analyze a specific task in a structured way. This is done by first breaking the job down into a sequence of basic steps, then identifying the potential or existing hazards associated with each of those steps, and finally, developing measures to control each identified hazard.

Question 4

What is the primary function of a risk matrix in the risk assessment process?

Accepted Answer

To prioritize risks based on their combined likelihood and severity.

Answer

A risk matrix is a tool used to qualitatively assess and prioritize risks. By plotting the likelihood of an event against the severity of its potential outcome on a grid, an organization can assign a risk score or level (e.g., low, medium, high). This allows for the prioritization of risks, ensuring that the most significant ones are addressed first.

Question 5

Which of the following is an example of a 'leading indicator' of safety performance?

Accepted Answer

The number of corrective actions closed from safety inspections.

Answer

Leading indicators are proactive, preventative, and predictive measures that track activities intended to prevent incidents. The number of safety inspections completed is a leading indicator because it measures a proactive safety effort. In contrast, lagging indicators, like the injury rate, measure failures that have already occurred.
