Eight local Rural Fire Service (RFS) units from Millthorpe, North West and Springside attended the scene and several firefighters were equipped with breathing apparatus.

The RFS was responding to a triple O call from a neighbouring property at 6.25 p.m.

TENS of thousands of dollars worth of damage was caused to both a large shearing shed and an adjacent steal-framed shed.

Farm equipment housed in one of the sheds was also damaged.

Yesterday morning police investigators declared the area a crime scene and forensic investigations were underway in order to determine the cause of the fire.

The firefighter was being treated for smoke inhalation and was in a stable condition yesterday afternoon.
