What is dust containment, and what strategies support it?

• A. Dust containment means keeping windows closed at all times.
• B. Dust containment is achieved by sprinkling water on floors only.
• C. Dust containment means reducing dust generation and spread; use dust barriers, negative air machines, HEPA filtration, controlled entry/exit, and cleanup protocols.
• D. Dust containment requires no protective equipment.

Answer: (C)

Dust containment is about reducing how much dust is generated and stopping it from spreading into clean areas. The strongest approach uses a combination of barriers, engineering controls, and careful cleanup to keep dust where it’s generated and away from workers and sensitive spaces. This includes setting up dust barriers or containment so the work zone is isolated, using negative air machines with HEPA filtration to pull air through filters and create pressure that prevents dust from drifting out, applying HEPA filtration to remove fine particles from the air, managing entry and exit to minimize cross-contamination, and following thorough cleanup protocols such as damp cleaning and HEPA-vacuuming to prevent dust from becoming airborne again. Why this matters: simply closing windows does not stop dust generation or guarantee containment, and sprinkling water on floors alone does not provide a reliable or comprehensive solution. Relying on no protective equipment ignores the need to protect workers during dust-prone tasks and cleanup. The described strategies together address both source control and containment, reducing exposure and environmental contamination.
