A Coraopolis company that is recalling kerosene that may have been contaminated by gasoline said it is looking into whether the death of a Mercer County Amish woman earlier this year may be connected to the contamination.

Ada Kurtz, 25, died June 27 of burns she suffered when she used what she thought was kerosene to light a wood-burning water heater.

New Wilmington Fire Chief Gary Wagner said at the time that gasoline fumes apparently ignited when Ms. Kurtz tried to light the heater June 21. Chief Wagner said the woman was using a container labeled "kerosene" but that it actually contained gasoline.

The Allegheny County medical examiner's office said Ms. Kurtz was burned over nearly 70 percent of her body.

"We are aware of that incident, and we are looking into it," said Karen Walsh, a spokeswoman for Pittsburgh Terminals Corp..

The company on Wednesday said it was issuing a recall after determining that a faulty valve at the company's supply center intermittently allowed gasoline to mix with some of the kerosene product.

However, the contamination occurred so sporadically that the company has no way to determine how widespread the danger may be.

"In some ways you could consider this [recall] overkill," another spokesman, Bob Post, said, referring to the recall region covering Western Pennsylvania east to Ligonier and includes part of Ohio to Wooster, south to Buckhannon, W.Va., and north to southwestern New York.

Because the contamination cannot be detected by consumers, the company cast the recall net far and wide, spokesman John Arnold said.

Fortunately, summer is an off-peak time for kerosene sales, although company officials could not say how much of the fuel it sells.

The primary customers are in industry. Some residential sales are made in Amish communities for lighting and cooking during the summer.

So far, the company has found only one outlet, in Erie, that sold a tank of kerosene contaminated with gasoline. In his business it's called "hot kerosene," Mr. Post said.

Anyone who bought kerosene supplied by Pittsburgh Terminals between May 1 and Aug. 19 should not use it. It should be returned to the retail outlet where it was purchased.

The company is offering full refunds for all purchases of its product between May and August. Regional recall centers soon will be set up to make the returns easier.

Anyone who has purchased kerosene in since May 1 is urged to take the product to one of 15 collection centers that have been set up in Western Pennsylvania and West Virginia.
