The trench is in front of a residence on the 4200 block of Elsa Road, near 48th Street and Mission Gorge Road.
San Diego Fire and Rescue Battalion Chief Glen Howard said Ozzy's Plumbing and Drain Services did not have the proper permits for trenching and shoring at the residence. He also said an employee of Ozzy's was placed at the bottom of a 15-foot trench when a partial collapse occurred and buried the man up to his stomach with dirt.
Battalion chief Howard said the man was rescued by two of his crews and denied medical service. The man was said to be unhurt and walked away from the scene.
Friday evening, a member of the California Division of Occupational Safety and Health showed up to investigate and said if the local plumbing company was without the correct permits, it could be fined.
Ozzy's Plumbing and Drain Services declined to comment.
Howard said had the man been buried up to his chest, the situation could have turned fatal. He voiced concern for his crews calling trench rescues more dangerous than fighting structure fires.
The homeowners and neighbors were not home at the time of the partial collapse and rescue; however, neighbors told FOX 5 three police officers lived in the home.
