SMSTS Risk Assessment and Mitigation 3

Question 1

When assessing the likelihood of harm in a risk assessment matrix, which of the following BEST describes a 'probable' event?

Accepted Answer

An event likely to occur at some point during the project

A 'probable' likelihood rating indicates the event is reasonably expected to occur given the nature and duration of the work.

Question 2

Under CDM 2015, who is responsible for ensuring a pre-construction information pack is provided to designers and contractors?

Accepted Answer

The client

Answer

CDM 2015 Regulation 4 places the duty on the client to ensure pre-construction information is provided to all relevant duty holders.

Question 3

A work at height task presents a risk of falling objects onto workers below. Which control measure should be implemented FIRST?

Accepted Answer

Establish an exclusion zone beneath the work area

Answer

An exclusion zone eliminates exposure by preventing workers from entering the drop zone, which is higher in the control hierarchy than PPE.

Question 4

What is the key difference between a 'hazard' and a 'risk' in the context of a site risk assessment?

Accepted Answer

A hazard is a source of potential harm; a risk is the likelihood and severity of that harm occurring

Answer

Hazard refers to the thing or condition that can cause harm, while risk combines the probability and consequence of that harm occurring.

Question 5

During a risk assessment review, a site manager identifies that a previously recorded control measure is no longer effective. What is the correct response?

Accepted Answer

Implement revised controls and update the risk assessment record immediately

Answer

Risk assessments must be updated whenever circumstances change and new controls implemented without delay to maintain worker safety.
