WASHINGTON (AP) _ Sunbeam Corp. is recalling over half a million humidifiers that have caused dozens of fires and four injuries. The humidifiers were sold under the brand names Sunbeam, Hankscraft and SunMark, and have water tanks that glow in the dark.

The Consumer Product Safety Commission said Tuesday that the Boca Raton, Fla., company has received 87 complaints about the humidifiers developing an electrical short, including 42 reports of fire.

In addition, three consumers suffered smoke inhalation and another suffered minor burns to her hands.

The humidifiers are white with green-, blue- or rust-colored covers. Sunbeam, Hankscraft or SunMark are written on the plastic cover.

The Sunbeam brand has service numbers 644 through 646 written on the back of the humidifier's motor housing, near the cord. The Hankscraft brand has service numbers 1260 through 1262 and the SunMark brand has service number 1260. Hankscraft and SunMark service numbers are written on the inside of the motor's plastic housing.

All the recalled humidifiers have date codes stamped on the plugs beginning with I001 through J226.

Only the humidifiers with these service numbers and date codes are being recalled. If a humidifier has a sticker on the motor's plastic housing showing a manufactured date of 1999 or later, it is not part of the recall.

Discount department and drug stores sold these humidifiers nationwide from March 1995 through December 1997 for $8 to $15.

The CPSC recommends that customers stop using the humidifiers immediately and call Sunbeam for a free replacement at (800) 440-4668, or access the company's Web site _ www.sunbeam.com _ for more information.
