What is the significance of keeping mobile equipment at least 15 feet away from checks and doors?

Keeping mobile equipment at least 15 feet away from checks and doors is significant for ensuring proper airflow is not obstructed. In underground mining operations, good ventilation is crucial for maintaining air quality and removing harmful gases from the mine environment. If mobile equipment is positioned too close to checks (entryways or stopping points) or doors, it can block air circulation, leading to hazardous work conditions for miners. Thus, maintaining this distance helps to ensure a safe environment where adequate airflow is available, enhancing worker safety and overall operational efficiency.

While considerations around maintenance, preventing collisions, and aligning with safety regulations are valid points, the primary importance of this distance revolves around ventilation and safeguarding the health of individuals working in the mine.
