Hang a two-pound all-purpose ABC dry-chemical fire extinguisher (from $25, www.smokesign.com) in the kitchen, and know how and when to use it. "An extinguisher can be a detriment if you waste time figuring it out, which can delay your call to 911," warns Tom Olshanksi of the U.S. Fire Administration. To operate: Pull the pin at the top, aim at the base of the fire, squeeze the lever/handle, and sweep from side to side.
