OSHA has cited Tampa Electric Co. and Gaffin Industrial Services Inc. after five employees were fatally injured, and one other suffered serious burns.

In June 2017, OSHA investigated the Big Bend River Station electrical power plant in Apollo Beach following the fatalities. Inspectors determined that the employees were burned when a blockage inside a coal-fired furnace broke free and spewed molten slag into the work area. Employees of Tampa Electric, Gaffin Industrial Services, and Brace Integrated Services Inc. died in the incident.
