Glue guns recalled

WASHINGTON -- Dollar Tree Stores Inc is recalling about 253,000 Chinese-made glue guns because they can short circuit, causing the gun to smoke and catch fire, the U.S. Consumer Product Safety Commission said Tuesday. The agency said Dollar Tree is aware of seven incidents in which the glue guns short-circuited, including two injuries involving electrical shock and burns. The "Crafters Square" hot melt mini glue guns were sold at Dollar Tree, Dollar Bill$, Dollar Express, Greenbacks, Only One $1, and Deal$ stores nationwide from February through August 2007 for about $1, the CPSC said.
