Halon

Halon was once considered the best choice of fire suppressing agents. When it was discovered that once discharged, Halon could significantly damage the ozone layer that protects us from damaging UV-B radiation, the production of Halon was discontinued in 1994. There are no cost-effective means of safely disposing of it, so guidelines recommend recycling and reusing existing Halon supplies. The EPA is responsible for testing agents for human exposure, ozone depletion, global warming potential and atmospheric lifetime. The result of this testing is that today, we have a variety of alternatives to Halon that are clean agents and produce no or low human and environmental impact.
