Shedding Light on MSHA’s Illumination Standard
A frustration mine operators frequently face relates to Mine Safety and Health Administration (MSHA) citations alleging insufficient illumination in work areas.
Given the subjective nature of MSHA’s illumination standard, mine personnel sometimes feel inspectors make it up as they go. For instance, a quarry manager several years ago was so upset about a citation alleging insufficient illumination that he suggested taking a light reading in the parking lot of the district office the night before the informal conference to demonstrate the relative brightness of the mine site work area.
