What must the SHMS provide for in regard to dust?

• A. Ensuring each coal mine worker's exposure to respirable dust is kept to an acceptable level
• B. A program to maximize dust generation
• C. Notification of dust events only
• D. Training in dust color identification

Answer: (A)

The key idea is that a Safety and Health Management System (SHMS) is built to control hazards, including dust, so that workers aren’t exposed to unsafe levels. In practice, this means setting clear exposure targets, putting in place practical controls, and regularly checking that those controls are working. Respiratory dust is a health risk because inhaling fine dust can lead to serious lung diseases, so the system focuses on keeping each coal mine worker’s exposure within acceptable limits through measures like ventilation, dust suppression, and exposure monitoring.

That’s why this option fits best: it states the fundamental requirement of the SHMS—ensuring every worker’s exposure to respirable dust remains at or below acceptable levels. The SHMS would also cover related elements like monitoring dust levels (personal and area sampling), implementing engineering and administrative controls, health surveillance, training, and prompt corrective actions if exposures drift upward.

Other choices don’t fit because they don’t reflect the core goal of protecting health. Maximizing dust generation would create more risk, notifying dust events alone misses ongoing exposure control, and training in dust color identification isn’t relevant to controlling respirable dust exposure.
