What are some harmful effects of Halon 1211 and Halon 1301?

Halon 1211 and Halon 1301 are known for their significant environmental and health impacts, particularly regarding ozone depletion. When released into the atmosphere, these chemicals contribute to the degradation of the ozone layer, which protects the Earth from harmful ultraviolet (UV) radiation. The depletion of this layer can lead to increased incidences of skin cancer, cataracts, and other health issues related to UV exposure.

In addition to their effects on the ozone layer, both Halon 1211 and Halon 1301 can pose health risks if inhaled. Exposure to these substances can lead to respiratory problems and other acute health effects, particularly in confined spaces where the concentration might be higher.

While Halon compounds are not classified as flammable, do not typically leave a sticky residue, and can produce toxic fumes, these characteristics are less central to their classification as hazardous substances compared to their contributions to ozone depletion and the associated health risks.
