OTAY MESA —
A semi truck carrying liquid oxygen sprung a leak Thursday, sending white clouds over a street in Otay Mesa in the early morning darkness.
Hazardous materials crews and Chula Vista and San Diego firefighters responded to the leak, which was reported shortly before 5 a.m. near La Media Road and Airway Road in Otay Mesa near the U.S.-Mexico border.
The leak was secured shortly before 6:20 a.m., more than an hour after crews first responded, said San Diego Fire-Rescue spokesman Alec Phillipp.
The driver of the truck was evaluated but not transported, Phillipp said.
