Which of the following is NOT a risk-control measure commonly used in Silent Library tasks?

• A. PPE.
• B. Unmonitored environment.
• C. Physical barriers.
• D. Supervised environment.

Answer: (B)

Reducing risk in Silent Library tasks comes from controls that limit exposure and ensure people can be overseen and respond quickly. PPE protects individuals from potential injuries by providing the right gear for the activity. Physical barriers keep hazards contained and prevent unintentional contact, guiding movement and access. A supervised environment ensures staff can enforce rules, monitor behavior, and intervene if something unsafe starts to happen. An unmonitored environment lacks that oversight and increases the chance of unsafe actions or delays in responding to problems, so it isn’t a risk-control measure.
