Who must the UMM immediately notify if an underground mine, or part of it needs to be sealed in an emergency?

• A. Local police
• B. Safety representative
• C. Inspector, ISHR or SSHR
• D. Family

Answer: (C)

When an underground mine or part of it must be sealed in an emergency, the person in charge on site must make immediate contact with the regulator and the workers’ safety representatives. The appropriate people to notify are the Inspector (the mining regulator) and the site Safety and Health Representatives—either the Independent Safety and Health Representative (ISHR) or the Site Safety and Health Representative (SSHR). This ensures that sealing decisions are overseen by the regulator and properly supported by those who represent the workers, with clear authority and documentation. Local police or family are not the immediate contacts for this regulatory and safety action, so they aren’t the correct channel in this scenario.
