Abstract: On July 26, 2013, with temperatures over 100 degrees Faeenheit, Employee #1, an inmate fire fighter, was fighting a vegetation fire. Although he drank the specified amount of water and had additional water with him, he perspired heavily and became dehydrated suffering muscles cramped. The employee reported the symptoms and was immediately moved to a shaded area to cool down and drink water under paramedic supervision. The employee's condition deteriorated and he was taken by ambulance to an area hospital, where he was treated for related medical conditions. Employee #1 was hospitalized for two days.
