A young female suffered burns to her hand after the ignition of gas from a compressed air duster. After debridement and dressing, the patient continued to have pain out of proportion to injury that was refractory to intravenous morphine. The material safety data sheet revealed that the chemical used was 1,1-difluoroethane. High temperatures can cause decompensation to form hydrofluoric acid. Calcium gluconate gel was applied topically to the patient's burns, which caused prompt and complete relief of her pain. A review of different compressed air duster products revealed that the main ingredient in each was a halogenated hydrocarbon. Although not considered flammable, all products have warnings regarding the possibility of ignition under various circumstances. Ignition of the gas in compressed air cleaners not only can cause flame burns, it can also cause chemical damage from exposure to hydrogen and fluoride ions. Prompt recognition and treatment is necessary to prevent severe injury.
一名年轻女性在压缩空气除尘器中的气体着火后手部烧伤。清创和包扎后，患者仍有与损伤程度不相称的疼痛，静脉注射吗啡治疗无效。材料安全数据表显示，所使用的化学物质是1,1 - 二氟乙烷。高温会导致其分解形成氢氟酸。将葡萄糖酸钙凝胶局部应用于患者的烧伤处，疼痛迅速完全缓解。对不同压缩空气除尘器产品的审查显示，每种产品的主要成分都是卤代烃。虽然不被认为易燃，但所有产品都有关于在各种情况下可能着火的警告。压缩空气清洁器中的气体着火不仅会导致火焰烧伤，还会因接触氢和氟离子而造成化学损伤。迅速识别和治疗对于预防严重损伤是必要的。
