35.2.3. Risk Matrix and Acceptable Risk Levels

Try these first

1. 1.

   What does ALARP stand for?

   Hint

   Think about what it aims to achieve regarding safety.

2. 2.

   What are the two main components of a risk matrix?

   Hint

   Consider what factors you evaluate in potential risks.

3. 3.

   What does the risk matrix assess?

   • Only severity
   • Only likelihood
   • Severity and likelihood

   Hint

   Consider what both factors contribute to assessing risk.

4. 4.

   True or False: ALARP means minimizing risks to the lowest level possible, regardless of cost.

   • True
   • False

   Hint

   Think about the balance that ALARP aims to achieve.

5. 5.

   A team is assessing risks for a new automated construction project. They identify a critical malfunction risk with a severity of 5 and a likelihood of 2. Using the risk matrix, calculate the overall risk level and suggest measures to achieve ALARP.

   Hint

   Remember to multiply severity and likelihood to find the risk level.

6. 6.

   Compare the approaches of two different companies assessing risks: Company A uses a strict dollar threshold for safety investments, while Company B employs the ALARP principle. Discuss how each approach impacts safety outcomes and regulatory compliance.

   Hint

   Think about the flexibility and responsiveness of each approach.
