Question 1

What is 'residual risk' in the context of workplace hazard management?

Accepted Answer

The risk that remains after all feasible controls have been implemented

Answer

The risk eliminated entirely by engineering controls

Answer

The initial risk identified before any analysis is conducted

Answer

The risk that has been formally transferred to a third-party contractor

Question 2

Which administrative control would be most appropriate for reducing worker chemical exposure levels?

Accepted Answer

Implementing job rotation schedules to limit individual exposure duration
