S11/GI Risk Assessment and Hazard Management

Question 1

What is the definition of a 'hazard' in a Queensland mining context?

Accepted Answer

A situation, thing, or substance with the potential to cause harm

Answer

A hazard is any situation, thing, or substance that has the potential to cause harm, injury, or illness — it does not need to have caused harm yet.

Question 2

In Queensland mining, 'risk' is best defined as:

Accepted Answer

The likelihood and consequence of harm arising from a hazard

Answer

Risk combines both the likelihood that a hazard will cause harm and the severity of the consequence if it does.

Question 3

Under the Coal Mining Safety and Health Act 1999 (Qld), who has a responsibility to identify and manage hazards at a mine site?

Accepted Answer

Everyone at the mine site

Answer

The Act places a duty of care on everyone at the mine site — workers, supervisors, managers, and contractors — to identify and manage hazards.

Question 4

Which control measure is considered most effective in the hierarchy of controls?

Accepted Answer

Elimination of the hazard

Answer

Elimination permanently removes the hazard from the workplace and is the most effective control because it removes the risk entirely.

Question 5

What does a risk matrix help mining workers determine?

Accepted Answer

The likelihood and severity of a risk to prioritise control actions

Answer

A risk matrix plots likelihood against consequence to give a risk rating, allowing workers to prioritise which hazards require the most urgent controls.
