A man and a woman in their mid 30s were critically injured with third-degree burns in a fire that broke out in a compact trailer where they were sleeping on Redwood Avenue in Del Rey early Saturday, December 5th, fire officials said.

The victims, whose relationship was not immediately known, suffered third-degree burns to their faces, arms and legs and were transported to the Ronald Reagan UCLA Medical Center in Westwood for treatment, Los Angeles Fire Department spokesman Brian Humphrey said. No other injuries were reported.

Five LAFD companies, including 36 Los Angeles firefighters, two LAFD rescue ambulances and four arson units were called at 4:55 a.m. to 4133 Redwood Ave., south of Washington Boulevard in Del Rey, where a windowless trailer was burning in the side yard of a single family home, Humphrey said.

Witnesses told firefighters that the man and woman were sleeping inside the trailer when it erupted in flames.

Reportedly assisted from the blaze by a male homeowner who came to their aid with a garden hose, the trailer occupants were freed from the flaming vehicle but severely burned upon firefighters’ arrival, Humphrey said. The homeowner was uninjured.

LAFD paramedics treated the victims on scene, while firefighters contained the flames to the trailer and extinguished the fire in about nine minutes. The nearby one-story home was not damaged.

A propane tank found at the scene is believed to have fueled the explosive flames, but the specific cause of the fire and estimated damage remains under investigation, fire officials said.
