HCBs explode when the pressure from gases produced by the chemical reaction ruptures the container. Typically, HCB ingredients are combined in a container, such as a soft drink bottle, which is then sealed and shaken. HCBs are explosives made from readily available chemicals, and instructions for making them are accessible on the Internet. Increasing awareness of HCBs and their dangers (particularly during summer months) among first-responders, parents, school staff members and others who work with youths might help reduce injuries associated with HCBs. The majority (35 ) of these persons were youths.HCBs are hazardous and especially dangerous if detonated in public areas. Among those events, 21 (16%) resulted in adverse health effects (i.e., respiratory symptoms, burns, and skin irritation) for 53 persons. This report describes the results of that analysis, which indicated that, during 2003–2011, a total of 134 events involving HCBs were reported from 15 states.
To determine the number of events involving HCBs in the United States and describe the factors associated with them, the Agency for Toxic Substances and Disease Registry (ATSDR) analyzed data from its surveillance system that tracks spills and leaks of hazardous substances. The volume of news reports of HCB explosions suggests they are not uncommon. Homemade chemical bombs (HCBs) are made from commonly found chemicals.
