After attending a couple of false alarms at Muswellbrook Fair (4.37pm) and Calvary Muswellbrook Retirement Community (6.28pm) on July 14, the 392 members attended a rubbish fire in Tobruk Avenue.

The crew discovered two chairs alight and quickly put them out with the first aid reel.

Then, at 8.27pm, both stations responded to a house fire.

The teams found the premises full of smoke, before extinguishing the blaze and departing the scene.

Later that evening, they cleaned up a diesel spill along the New England Highway, at the intersection of Manning Street.

"It was a busy period for the crew," a FRNSW 392 Muswellbrook spokesperson said.

"We'd get back to the station, then the bells would go off again.

"But, it's a timely reminder for residents to make sure they have working smoke alarms."
