Fiskars Canada is voluntarily recalling its propane-powered string trimmers due to safety concerns. The SmartPower Propane 4-Cycle Curved Shaft String Trimmer, sold at Canadian Tire stores, could pose a danger when engine vibration allows the propane canister to rotate. This causes abrasion to the fuel line and possible flammability created by gaseous propane being released through the damaged fuel line during both use and storage.

Most propane is treated with an ingredient that smells like spoiled eggs when the tank leaks. This safety measure helps consumers detect leaks. But some of the propane in about 700 rail cars of propane gas sold in portable cylinders from Morris Ill.-based Aux Sable Liquid Products do not have sufficient levels of the odorant.

As a result, the U.S. Consumer Product Safety Commission, in cooperation with Aux Sable Liquid Products announced a voluntary recall of the propane cylinders.
