Harnesses must be visually inspected by the user before each use and formally inspected by a competent person at manufacturer-recommended intervals.

- Granting employment authorization to new workers
- Controlling high-risk tasks to ensure proper precautions are in place before work begins (Correct answer)
- Issuing parking permits for site vehicles
- Approving overtime payments for workers
Correct answer: Controlling high-risk tasks to ensure proper precautions are in place before work begins
A permit to work is a formal document that authorizes specific high-risk tasks and confirms that all necessary safety measures are in place.

Correct answer: An unplanned event that could have resulted in injury or damage but did not
A near miss is an unplanned event with the potential to cause injury or property damage but where no harm actually occurred — it must still be reported and investigated.

Correct answer: The principal contractor and site management
The principal contractor has overall responsibility for coordinating health and safety on site, including ensuring all subcontractors comply with site safety rules.
