What safety precautions are MOST important during a partial renovation of a building while keeping...

During partial building renovations while operations continue, the primary safety priority is establishing clear barriers and restricted zones to separate construction activities from business functions. The correct choice is:

Setting up barriers to create a safe perimeter, restricting staff access, and enforcing PPE requirements in work zones.

This approach prevents exposure to hazards such as dust, noise, falling objects, and construction-related accidents.

Why the other options are incorrect:

(A) Monthly air quality testing is beneficial but does not address immediate physical safety risks.

(B) Hearing protection and eye wash stations help in construction areas but do not sufficiently protect the larger workforce from hazards.

(D) Requiring all staff to wear PPE is excessive unless they are directly involved in construction-related tasks. A security checkpoint may be useful but is not the most critical precaution​.
