EHZ is an abbreviation for Extremely Hazardous Substances. It refers to a classification of chemicals or substances that pose a significant risk to human health and the environment in case of accidental release or exposure. EHZ substances are typically characterized by their high toxicity, reactivity, flammability, or the potential to cause severe acute or chronic effects.
These substances are regulated under various national and international frameworks aimed at preventing or minimizing their adverse effects. The United States Environmental Protection Agency (EPA), for example, has established a list of around 350 EHZs under the Emergency Planning and Community Right-to-Know Act (EPCRA) and the Clean Air Act (CAA). These substances include, but are not limited to, highly toxic gases, corrosive substances, explosive materials, and certain radioactive compounds.
EHZs are subject to strict reporting and handling requirements, and facilities that manage or store these substances are required to comply with regulations such as hazardous material storage, emergency response planning, and community notification. The goal of regulating EHZs is to ensure the safety of workers, nearby communities, and the environment by reducing the risk of accidental releases or exposures, as well as to promote transparency and public awareness regarding potential hazards.
In summary, EHZ stands for Extremely Hazardous Substances, which signifies chemicals or materials with high toxicity, flammability, reactivity, or other properties that can pose significant risks to human health and the environment in case of accidental release or exposure.
