Another large wildfire has been started by a pyrotechnic device at a gender reveal party. CAL FIRE determined that the El Dorado Fire which has burned over 7,000 acres near a heavily populated area of San Bernardino County in southern California was started by the use of a smoke generating pyrotechnic device. The intent was to produce pink or blue smoke to inform bystanders (waiting breathlessly nearby) about the gender of a fetus.
The fire began at 10:23 a.m. on September 5, 2020 in the El Dorado Ranch Park in Yucaipa. It spread from the park north to Yucaipa Ridge which separates Mountain Home Village and Forest Falls from the City of Yucaipa.
At least two other gender reveal parties that used pyrotechnic devices have started wildfires in recent years.
The 46,000-acre Sawmill Fire southeast of Tucson, Arizona was ignited in 2017 by an off-duty Border Patrol agent. He mixed colored powder into a Tannerite exploding target which would show blue or pink smoke when shot with a rifle, according to his attorney, Sean Chapman. The target exploded as planned and started what became the Sawmill Fire. A witness helpfully recorded a video of the explosion.
In 2020 a gender reveal party in Florida went wrong and sparked a 10-acre fire, also caused by a Tannerite exploding target.
