The injuries sustained were classified as minor to moderate‚ said ER24.

Four of the injured were believed to have been fire fighters.

In an area that's seen its share of dangerous and destructive wildfires, a new fire truck will make a huge difference for Sapulpa firefighters.

For one thing, it's powerful - with a 350-horsepower engine. And, its tank is much larger than any of the other trucks the Sapulpa department has, holding 3,000 gallons of water.

Firefighters say having more water is critical in fighting fires in Creek County.

"We cover 92 square miles - 23 of that is our incorporated city limits," said Chief David Taylor.

So the rest is in rural and often very rugged areas without access to water.

Taylor said the new truck will allow firefighters to bring more water with them, and less time shuttling water to a fire means more time being able to put out the flames.

"A lot of times, when you get out on structure fires, even the brush fires, water supply is huge," he said.

Manufactured by Sutphen, out of Columbus, Ohio, it has a variety of features because of its dual nature as an engine and rescue truck.

These include a 2,000-gallon per minute pump, a tank that can hold 750 gallons of water, hydraulic rescue tools and breathing air for refilling air pack bottles.

He said the specs were very difficult in building the truck.

"Speccing a rescue truck is hard enough, speccing an engine is hard enough. When you try to spec one that does both...we've been working on it for three or four years." He called it a "multi-year process."
