bizSAFE Risk Management and RMIT Process 2

Question 1

What is a 'risk matrix' used for in WSH risk assessment?

Accepted Answer

To evaluate and categorise risks by combining the likelihood of occurrence with the severity of potential harm

Answer

A risk matrix is a tool that combines the likelihood of a hazardous event occurring with the severity of its potential consequences to produce a risk level (e.g., low, medium, high), which guides the priority and urgency of control actions.

Question 2

What is the difference between a 'hazard' and a 'risk' in WSH terminology?

Accepted Answer

A hazard is something with potential to cause harm; a risk is the likelihood and severity of harm occurring from that hazard

Answer

In WSH, a hazard is the source of potential harm (e.g., a wet floor, a chemical substance), while risk is the combination of the likelihood that harm will occur and the severity of that harm. Understanding this distinction is fundamental to risk management.

Question 3

Under the WSH (Risk Management) Regulations, which of the following workplaces is required to conduct a formal risk assessment?

Accepted Answer

A construction site with 5 workers

Answer

The WSH (Risk Management) Regulations apply to workplaces covered by the WSH Act where work is carried out by workers. A construction site, even with a small number of workers, is a covered workplace and requires a formal risk assessment.

Question 4

What should a risk assessment document include to be considered complete under Singapore's WSH framework?

Accepted Answer

Description of the activity, identified hazards, risk level, control measures, residual risk, and persons responsible

Answer

A complete risk assessment document should include the work activity description, all identified hazards, the evaluated risk level, the control measures to be implemented, the residual risk after controls, and who is responsible for implementing the controls.

Question 5

What is the purpose of administrative controls in the hierarchy of risk control measures?

Accepted Answer

To change how work is done through procedures, training, and work schedules to reduce exposure to hazards

Answer

Administrative controls manage risk by changing work processes, implementing safe work procedures, providing training, and regulating working hours or shift rotations to reduce worker exposure to hazards. They do not eliminate the hazard but reduce exposure.
