The term "dangerous chemicals" refers to any substance that poses a significant risk or harm to humans, animals, or the environment when it is used, stored, or disposed of improperly. These chemicals can have various properties such as being flammable, corrosive, explosive, toxic, or carcinogenic, and may cause severe health effects ranging from skin irritation to respiratory problems, organ damage, or even death if not handled with proper precautions. Examples of dangerous chemicals include hydrochloric acid, ammonia, chlorine gas, and asbestos fibers among many others. It is essential that individuals who work with these substances are well-trained in handling them safely and have the necessary protective equipment to minimize any potential harm they may cause.
