Some chemicals that are hazardous have been developed by military organizations for use in warfare. Examples are nerve agents such as sarin, mustards, and choking agents. It might be possible for terrorists to get these chemical warfare agents and use them to harm people.
Many hazardous chemicals are used in industry (for example, chlorine, ammonia, and benzene). These types of hazardous chemicals also could be obtained and used to harm people, or they could be accidentally released.
