RECALLS

Furniture refinisher is being recalled because the product and its vapors can seep or leak from the nozzle base at the top of the can, posing a risk of fire and chemical injuries. Sherwin-Williams and Brockway Standard recalled about 3,000 quart cans of Formby's Conditioning Furniture Refinisher, sold individually and as part of Formby's Introduction to Refinishing Kit, after receiving one report of an employee suffering minor burns when vapors ignited, the Consumer Product Safety Commission said. The recalled products have the following lot codes written in black ink on the bottom of the can: A961600, A961610, A961620, A961630, A967270 and A969330. Cans with blue ink codes are not being recalled. The CPSC advises consumers to stop using the refinisher immediately and to place the product upright in a well-ventilated area away from any source of ignition.
