Entitled, “NIOSH Focuses on Workplace Safety”, this image depicts the interior of an Illinois Basin coal mine, where workers are subjected to a double whammy. The mines walls and ceilings are composed of very weak rocks, and very high stress levels exerted upon those rocks. As a result, the rocks can crush and fall, causing injury or death to coal miners. In this photo, a NIOSH researcher is evaluating a “roof fall”, and trying to determine the best support structure to reinforce the rock. The photographer, CDC Lead Research Scientist, Gregory Molinda, earned a Second Place award in the 2008 CDC Connects Annual Public Health in Action Photo Contest, in the category of “Domestic Programs”.
