The Daytona Beach News-Journal reports Thomas Wood had been in critical condition since the Monday accident at a RaceTrac gas station in Daytona Beach.
Wood and another man had been cleaning the tanks when Wood fell in.
Co-worker Dustin Reed told authorities the tank’s lid was open when he went to his truck to do paperwork. When he returned a short time later, he didn’t see Wood.
He found the man about two minutes later at the bottom of the 6-foot-deep well.
Daytona Beach Fire Department crews performed CPR and took Wood to the hospital, where he was listed in critical condition.
The Occupational Safety and Health Administration is investigating.
