Firefighters usually respond to emergencies, but Sunday morning an emergency came to first responders in Aurora Colorado.

A 23-year-old woman was going into labor on the driveway of a fire station and as soon as the baby was born, firefighters also saved it from their sprinkler system.

“Four in the morning, someone is banging on the back of the firehouse and it’s not tragic. That was surprising,” Fire Engineer Zac Varela told, KTLA sister station KDVR in Denver reported.

Almost instantaneously, they got a call as well and crews prepared to head out

“When I see the door come open, there’s a gold SUV on the ramp. I am thinking, ‘What idiot parked on the ramp at the firehouse?’,” Varela said.

Varela says the pregnant woman was in the passenger seat of the SUV and her mother was trying to soothe her.

Firefighters then laid the mom-to-be down on the lawn on top of a blanket. “We are prepared to deliver this baby right on the front lawn. Fortunately, our ambulance pulled up at that time,” Varela said.

And not a moment too soon. “As soon as we picked her up, we heard that hiss, that ‘whew’ and they opened up,” Varela said of the sprinkler system.

They saved her from a soaking and lifted her into the ambulance.

“She said, ‘I have to push.’ Our guy said, ‘Go ahead.’ And two pushes and we had a baby girl right there,” Varela said. Right there in a makeshift delivery room near a busy intersection.

The new mom was carrying on an uncommon family tradition. The woman’s mother explained how almost 20 ago her daughter was born in the back of an ambulance and delivered by Aurora firefighters, Varela said.

“We are really happy when we deliver a healthy baby. A lot of our calls don’t always go that great,” he said.

The baby girl was born at 4:22 a.m., not more than 10 minutes after mom and grandma arrived at the fire station.

“Rather than giving birth on the freeway, I guess they chose our firehouse,” the fire engineer said.
