A.To ensure that high-risk maintenance tasks are systematically assessed, hazards identified, and safety controls authorized before work begins

B.To grant technicians permission to work overtime and claim additional compensation

C.To verify that the sub-contractor has been paid their initial mobilisation fee

D.To allow unregistered personnel to operate heavy industrial equipment during emergencies

Explanation: A Permit to Work (PTW) system is a formal written safety protocol used to manage high-risk activities (such as hot work, confined space entry, or electrical isolation). It ensures hazards are evaluated, isolation is verified, and work is conducted under strict controls.

10Under the Hierarchy of Controls for risk management, which method is considered the most effective way to address a workplace hazard?

A.Elimination of the hazard at its source

B.Provision of Personal Protective Equipment (PPE)

C.Implementation of administrative rules and safety warnings

D.Engineering controls such as safety guards and physical barriers

Explanation: The Hierarchy of Controls ranks risk control methods from most effective to least effective: Elimination, Substitution, Engineering controls, Administrative controls, and PPE. Removing the hazard entirely is always the most effective measure.
