Other places stated in the PHMP for gas monitoring include which of the following?

• A. Other places stated in the mine's PHMP for gas monitoring
• B. The surface water treatment plant
• C. The training center
• D. The ventilation column

Answer: (A)

Gas monitoring locations are defined by the PHMP itself. The plan can specify not only the main monitored areas but also any other places where monitoring is required, as listed in the PHMP. So the best choice is the option that says other places stated in the mine's PHMP for gas monitoring, because it correctly reflects that the PHMP may designate additional locations for monitoring beyond the primary areas. The other options refer to specific facilities, which may or may not be included in a given PHMP, but they don’t capture the principle that monitoring sites are defined within the PHMP itself.
