✓ Correct answer: A. All relevant work must cease immediatelyA prohibition notice requires that the affected work activity stop without delay because of a serious and immediate risk.
Why the other options are incorrect:
• Work may safely continue: The notice demands a halt to work, not permission to carry on.
• There is only a minor problem present: A prohibition notice is triggered by serious hazards, not trivial ones.
• Employees need additional training: While training may be indicated later, the notice's immediate effect is to stop the work.
• A fresh risk assessment must be conducted: A risk assessment may follow, but the notice's primary demand is that work stops now.
