Final answer:
Chemicals that are toxic, carcinogenic, irritating, or corrosive are considered as hazardous substances, which include toxic, corrosive substances like acids and bases. The US Environmental Protection Agency categorizes these materials as characteristic hazardous wastes, which can pose significant health risks.
Step-by-step explanation:
Chemicals that are toxic, carcinogenic, irritating, or corrosive are part of the hazardous category of substances. These materials pose a variety of risks to human health and the environment. Toxic chemicals can include those that are reactive, ignitable, and corrosive. For instance, chemical carcinogens like cadmium compounds can increase the incidence of cancer. Corrosive substances, like hydrochloric acid, can cause severe damage to skin and eyes and even burn through clothing. The US Environmental Protection Agency (EPA) categorizes materials that exhibit these properties as characteristic hazardous wastes.
Exposure to hazardous chemicals whether through ingestion, inhalation, or skin contact can affect various body systems including the nervous system, respiratory system, and brain. It's important to handle these chemicals with caution and follow appropriate safety measures to minimize risks of exposure and potential health hazards. The identification and categorization of these hazardous substances are essential in ensuring public safety and environmental protection.
