Current methods for testing blast pressures produced by fireworks are ad hoc and differ substantially from established methods for assessing injury risks from explosives. In this experimental study, pressure-versus-time waveforms were measured as a function of distance from the source for four consumer firecrackers and one consumer bottle rocket. Pressure-versus-time data were collected at 10 MHz using a piezoelectric blast pressure sensor at distances 75 mm, 150 mm, 225 mm, and 300 mm from the source. While large variations in peak pressure were observed, in some trials, peak blast pressures over 100 kPa were observed, which suggests a risk of primary blast injury. The results support analysis of pressure waves produced by consumer firecrackers using established methods to quantify blast waves and to evaluate the risk of primary blast injury by comparing peak pressure and positive pulse duration to injury thresholds for specific body systems. Similar methods can be applied to result in comparable measurements for other firework devices.

用于测试烟花产生的爆炸压力的当前方法是临时的，并且与评估爆炸物伤害风险的既定方法大不相同。在这项实验研究中，测量了四个消费类鞭炮和一个消费类瓶装火箭的压力-时间波形随距源的距离的变化。使用压电冲击压力传感器在距源75 mm，150 mm，225 mm和300 mm的距离处以10 MHz的频率收集压力与时间的数据。尽管观察到峰值压力变化很大，但在某些试验中，观察到爆炸峰值压力超过100 kPa，这表明存在爆炸危险。结果通过将峰值压力和正脉冲持续时间与特定人体系统的伤害阈值进行比较，可以使用既定方法量化爆炸波并评估初级爆炸伤害的风险，从而支持消费性鞭炮产生的压力波的分析。可以应用类似的方法来对其他烟花设备进行可比的测量。
