Marylanders might be feeling wilted by the recent spell of 90-degree-plus temperatures, but for some workers the heat can be more than uncomfortable -- it can be dangerous.
Craig Lowry, chief of enforcement for Maryland Occupational Safety and Health, said the riskiest jobs for heat-related illness include work in steel mills, asphalt paving and roofing. He described three stages of heat-related illness:
*Heat stress, characterized by symptoms such as dizziness, headache, nausea.
*Heat cramps, in which the major muscles lose fluids and contract painfully.
*Heat stroke, an emergency situation in which the skin becomes dry and hot, internal body temperature rises, and vital organs can be harmed.
