The primary focus during construction and renovation to reduce the spread of dust is which of the following?

• A. Installing barriers
• B. Reducing dust
• C. Wetting surfaces
• D. Delaying work

Answer: (B)

The main idea is to minimize dust that could spread into patient areas during construction or renovation. Focusing on reducing dust directly targets the outcome you want: less dust circulating beyond the work zone. Specific measures like installing barriers or wetting surfaces are important tactics to achieve that goal, as they help contain dust and prevent it from becoming airborne, but the overarching objective is to lower the overall dust load in the environment. Delaying work is rarely the primary, ongoing approach.
