San Francisco rescue technicians had to obtain an OSHA permit before going into a sewer pipe to extricate a man early Sunday.
After all the proper protocols were observed, firefighters found the man and rescued him, extricating him from the pipe shortly after 5 a.m., San Francisco Lt. Mariano Elias told 7news.
The man was taken to San Francisco General Hospital with serious injuries.
A man called 9-1-1 telling dispatchers he heard scraming coming from a manhole.
Elias said the victim somehow got into the pipe which was 20 feet below street level. At some point, there was a downward drop in the pipe, and the man fell on his head.
