Two sheriff's deputies were injured after a trailer caught on fire at the Pitchess Detention Center in Castaic on Tuesday.
The deputies were conducting a training exercise on a mobile shooting range when a fire broke out at around 9:30 a.m.
"Their condition is stable, but they remain in critical condition due to injuries primarily related to burns. Importantly, no surgical intervention has been required at this time," the Los Angeles County Sheriff's Department (LASD) said in a statement.
Both deputies were taken to Henry Mayo Newhall Hospital.

LASD did not release the names of the deputies who were injured, but the department described them as a 20-year veteran assigned to Sylmar Court and a 17-year veteran assigned to the North County Correctional Facility.
While firefighters battled the flames that broke out on the mobile range trailer, the Pitchess Detention Center was under lockdown as a precautionary measure. The blaze did not pose a threat to inmates, according to officials.
As an added safety precaution, all mobile shooting ranges in the country have been temporarily closed.
