Three workers were killed at a construction site in Key Largo on Jan. 16, authorities said.
The deceased workers are identified as 34 year old Elway Gray of Fort Lauderdale, 49 year old Louis O’Keefe of Little Torch Key and 24 year old Robert Wilson of Summerland Key.
Three Sheriff’s deputies who were exposed to fumes taken to Mariner’s hospital for treatment.
A Miami-Dade County Hazmat team responded to assist with the scene. They performed tests in the pipe where the workers collapsed. Their tests revealed there was both Methane gas and Hydrogen Sulphide gas coupled with low levels of oxygen in the pipe.
The Medical Examiner’s Office responded and transported the bodies to their offices where autopsies will be performed. The Occupational Safety and Health Administration (OSHA) has started an investigation into the circumstances of the workers deaths.
