Which of the following is a mandatory PHMP?

• A. Mine ventilation
• B. Noise control
• C. Water management
• D. Electrical safety

Answer: (A)

The key idea here is that a mandatory PHMP focuses on documenting how a mine will manage a specific health hazard. In coal mining, ensuring proper air quality and controlling gas and dust are fundamental health risks, and ventilation is the primary way to manage those risks. A formal Mine Ventilation plan sets out how the ventilation system will be designed, monitored, and adjusted, what controls are in place to keep methane and other contaminants at safe levels, and how issues will be detected and responded to. Because controlling air quality and ensuring a safe breathing environment is central to health protection in a coal mine, a plan dedicated to mine ventilation is required as a PHMP.

Noise control, water management, and electrical safety are all critical safety areas, but they are typically addressed through other plans or regulatory requirements specific to those hazards rather than a PHMP focused on health management.
