triperoxide diamine, which served as a detonator for the highly stable ammonal-type secondary charge. An unnamed person suffered "injuries typical of blast injury, such as tympanic membrane rupture, globe injury, and severe burns" due to "close proximity exposure to detonation of the mixed Tannerite blend". On April 23, 2017, Dennis Dickey, an off-duty U.S. Border Patrol agent, shot a Tannerite target in a gender reveal celebration on state trust land south of Tucson, Arizona, which accidentally ignited the nearby dry brush and started a fire known as the Sawmill Fire. At the time, winds were gusting up to and the National Weather Service had issued a fire watch in the area. By the time the wildfire was mostly contained one week later, it had jumped over the Santa Rita Mountains and crossed State Route 83, spreading into the historic Empire Ranch and the surrounding Las Cienegas National Conservation Area. The estimated damage caused by the blaze was $8.19 million. Dickey pleaded guilty in September 2018 to a misdemeanor violation of U.S. Forest Service regulations and was sentenced to five years' probation. He also was ordered to pay restitution, with an initial payment of $100,000 (taken from his retirement fund) and monthly payments of $500 per month thereafter for 20 years unless his income changes significantly. The payments will total $220,000 over the 20 years, after which the case will return to a judge to make a decision about future restitution. The eventual restitution payments could hypothetically be up to $8,188,069. On April 23, 2021, another gender reveal party involved of Tannerite detonated at the bottom of a quarry in Kingston, New Hampshire, rattling homes in not just New Hampshire but also parts of north-eastern Massachusetts. Although no one was injured, some homes experienced damaged foundations and water from the faucet briefly turned brown. The person who purchased and detonated the Tannerite turned himself in to Kingston police. References Binary explosives
