The cause of a fire at a lumberyard in Hammond on Tuesday was electrical.

Clarence-Rockland Fire Chief Brian Wilson said a dump truck struck an overhead power line which caused a storage shed at J. Lalonde et Fils RONA building supplies to catch fire.

Firefighters responded to the scene at around 2:30 p.m. Tuesday afternoon and got the fire under control.  There were no injuries.

Wilson said damage is estimated at $500,000 to $600,000.

The business remains open.
