Two people were injured, one of which suffered bad burns to his body, after hydraulic fluid sparked a large flash fire at a business in El Cajon.
The fire broke out shortly before noon on the 800 block of W Bradley Avenue in El Cajon, Heartland Fire officials said.
When the fire started, it happened inside the plant next to a piece of equipment, which quickly started to burn. It is unclear how the hydraulic leak caused the fire, officials said.
Heartland Fire officials said they quickly quelled the fire. However, a plume of black smoke could be seen rising from the fire behind Cowles Mountain.
One victim suffered smoke inhalation and a second suffered bad burns, though officials do not have word on the extent of his injuries.
HAZMAT crews responded to the scene as well. SDG&E officials turned off the gas.
No other information was immediately available.
