Who must inform others about necessary safety information in a mine?

The correct choice highlights the responsibility of coal mine workers and other persons present within the mine environment to communicate necessary safety information. This is in line with the principles of safety management systems and the overall objective of maintaining a secure working environment.

In mining operations, every individual has a role to play in ensuring safety standards are upheld and disseminated among their peers. Coal mine workers, along with other personnel present, must remain vigilant and proactive in sharing information that pertains to safety procedures, hazards, and risks associated with their activities. This collective responsibility helps to foster a culture of safety where everyone is encouraged to contribute to a safer workplace.

While site managers, government inspectors, and training personnel also play important roles in the safety framework, their responsibilities are often more focused on oversight, compliance, or training rather than actively informing others regarding safety information on a day-to-day basis within the dynamic conditions of a mining site. Therefore, the emphasis on coal mine workers and others in the mine effectively captures the essence of shared safety accountability, making it the correct answer to the question.
