S11/GI Risk Assessment and Hazard Management 3

Question 1

In the hierarchy of controls, which option must always be considered first before others?

Accepted Answer

Elimination of the hazard from the workplace

Answer

Elimination is always considered first because it permanently removes the hazard, providing the highest level of protection with no ongoing reliance on controls.

Question 2

Which of the following is an example of 'substitution' as a control measure in Queensland mining?

Accepted Answer

Replacing a toxic solvent with a less hazardous cleaning agent

Answer

Substitution replaces a hazardous material, substance, or process with a less hazardous alternative, reducing the level of risk at the source.

Question 3

Installing a physical guard around a conveyor belt is an example of which type of control?

Accepted Answer

Engineering control

Answer

Engineering controls are physical modifications — such as guards, barriers, or ventilation systems — that reduce exposure to a hazard by design.

Question 4

Which of the following is an example of an administrative control in a mining environment?

Accepted Answer

Implementing a permit-to-work system for high-risk tasks

Answer

Administrative controls are work practices, procedures, and systems — such as permits-to-work, job rotation, and training — that change how work is performed to reduce risk.

Question 5

PPE is considered the least preferred control in the hierarchy of controls because:

Accepted Answer

It relies on correct worker use and does not remove or reduce the hazard itself

Answer

PPE only protects the individual if worn and used correctly — it does not eliminate or reduce the hazard, meaning the hazard remains present at full strength.
