Abstract: At approximately 9:00 p.m. on August 20, 2005, Employee #1 and a coworker were working in a kettle popcorn concession. A portable gasoline-powered generator was powering lights and other electric equipment in the concession booth in which a propane-fueled cooking kettle was being used to make fresh kettle corn popcorn. The kettle was located inside the booth, and the gas generator was about 5 feet away, on the ground outside the booth. When the generator stopped, Employee #1 went to refuel the generator from a 2.5 gallon gas can. Gas spilled out of the can onto Employee #1 and onto the generator during the refueling. The coworker, who was operating the kettle, saw a vapor trail ignite from the kettle to the generator, and the area around Employee #1 erupted in flames. Employee #1 was transported and admitted to UCSD Medical Center with second-degree burns to his stomach and arms.
