Which maintenance/engineering practice primarily reduces airborne dust exposure?

• A. Sanitary design principles
• B. Minimize use of air compressors
• C. Maintain tools
• D. Monitor and reduce dust levels

Answer: (D)

Measuring and controlling airborne dust exposure is addressed by monitoring dust levels and taking actions to reduce them. This creates a feedback loop: you assess the air to know how much dust people are breathing, then implement controls (like ventilation improvements, targeted dust collection, enclosures, and enhanced housekeeping) to bring those levels down and keep exposure safe. Among the options, monitoring and reducing dust levels directly focuses on both measuring and lowering the airborne dust people are exposed to, which is why it is the best choice. The other practices aren’t primarily about reducing airborne dust exposure: sanitary design principles aim at cleanliness and preventing contamination, maintaining tools is about equipment upkeep, and minimizing the use of air compressors could affect dust in specific cases but does not systematically address exposure levels.
