Nearly all on-duty Hamilton firefighters were called out to battle a large industrial blaze that burned for nearly four hours through the night Tuesday.

The flames apparently started in a pile of wooden skids outside Prema Canada on Bond Street in Dundas around 11:45 p.m. and then spread to the main building.

The fire was knocked down about four hours later.

The company makes tire repair kits and patches. Hazmat (hazardous materials) crews were called to the scene and nearby home were evacuated as a precaution. The affected residents were allowed back into their homes around 4 a.m. Wednesday.

The ministry of the environment was called to the scene but investigators are reportedly not concerned about ground water or air quality in the area.
