An electronic cigarette exploded and killed a man in Florida this month, the authorities said, in what appears to be the first death attributed to vaping products in the United States.

The man, Tallmadge D’Elia, was at his home in St. Petersburg, Fla., on May 5 when the device, also known as a vape pen, exploded, according to William A. Pellan, the director of investigations at the medical examiner’s office for Pinellas County.

He confirmed that the cause of the accidental death was a “projectile wound to the head,” and that Mr. D’Elia, 35, had suffered burns on about 80 percent of his body. It appeared that the explosion had started a fire in the bedroom where he was found.

One of the pieces removed from his head featured the logo of Smok-E Mountain Mech Works, which is based in the Philippines.
