To be held this Saturday at Sunny Corner State Forest, the exercise will involve 200 firefighters from across the region as well as 50 support personnel and 43 trucks.

Chifley NSW Rural Fire Service Inspector Mick Holland said the annual training day was vital to ensure crews are ready for the busy season ahead.

On the day, crews will work their way through 18 different scenarios including car accidents, house fires, use of a thermal imaging camera, firefighting techniques and communication exercises.

Firefighters will also practice what to do if they are overrun by a fire (as pictured).

“It’s a chance for brigades to hone their skills,” Inspector Holland said.

“We always get really good feedback from the crews.”

Training will run from 7.30am until 5pm.
