One victim suffered burns in a small backyard explosion in Clairemont, San Diego Fire-Rescue (SDFD) officials said.
The call first came in for a structure fire on the 4100 block of Willamette Avenue at approximately 1:01 p.m. Thursday. The location is just a few blocks from the Clairemont Town Square.
Fire officials with the hazardous materials division told an NBC 7 crew that a man was pouring an unknown liquid into a hole in his backyard when a small explosion occurred.
The patient suffered burns to his legs and was taken to UC San Diego's Burn Center. The extent of his injuries is unknown.
A private cleanup company handed the cleanup. SDFD's Hazmat crew did respond to the scene, but determined there was no hazard.
Fire officials referred the building to City Building Inspectors because of code issues.
No further information was available.
