What role does a danger board serve in a mining context?

In the context of mining, a danger board serves the critical function of warning about hazardous areas. These boards are visibly placed to ensure they are easily seen by miners and can effectively communicate the presence of potential dangers, such as unstable ground, high voltage areas, or the presence of hazardous materials. By alerting workers to these risks, danger boards play a vital role in maintaining safety on site.

The other options, while relevant to site safety, do not specifically describe the primary purpose of a danger board. Guiding miners to safe zones, marking locations of equipment, and providing directions for evacuation are important aspects of mine safety, but they are not the direct functions associated with the role of a danger board. Instead, danger boards specifically focus on the immediate hazards that workers should be aware of to prevent accidents and injuries.
