When job site safety, and the unfortunate outcomes that can come from overlooking safety protocols, are covered in Cleaner, it oftentimes has to do with trench collapses or the dangerous toxic gas environments found in sewers.

But an incident in Johnstown, Pennsylvania, last week shows an example of the above-ground dangers that workers have to be mindful of as well. While working on a sewer project Thursday, two employees of Insight Pipe Contracting were injured and a third one died when a machine made contact with overhead power lines, carrying 23,000 volts of electricity to where the employees were working.

According to a report in the The Tribune-Democrat, Christopher Diaz, 30, was standing on the ground leaning against a telescopic forklift being used on a pipe lining job. He died from electrocution when the machine made contact with high-tension lines overhead. The two other workers were shocked when they attempted to pull Diaz away from the machine.

An OSHA investigation into the incident is ongoing.
