Firefighters continue to battle Border Fire in Potrero

SAN DIEGO (KUSI) — Some firefighters are working on the fire lines around the clock.

But we’re told this is what they’ve been training for.

It’s been a long couple of days for fire crews, who have been working around the clock to stop the Border Fire.

For many, the longer the fires rage, the longer they will be sleeping, eating and living at base camps in Potrero.

What began as a 50-acre brush fire, quickly became a 7,500 acre wildfire in little over 24 hours.

All the while, almost 1,500 firefighters were on duty.

Potrero County Park is unrecognizable, filled with fire crews from numerous countys’ sheriff’s office personnel, border patrol and paramedics.

Cal Fire spokesman Scott McLean has been up since 3 a.m. battling the flames.

But hundreds of others will spend the night sleeping, resting and refueling before heading back out.

The majority of the fire was fought in the air by planes with steep hills making it too dangerous for ground crews.

Fire crews wait at the bottom of the hills, assigned to keep watch over the flatlands, guarding structures, protecting Potrero.

In doing so, three firefighters were injured. Two of the injuries were heat and dehydration related.
