In what year did the use of Halon come to an end?

The use of Halon as a fire suppression agent significantly declined due to its detrimental impact on the ozone layer. The decision to phase out the use of Halon was primarily influenced by the Montreal Protocol, an international treaty established in 1987 to protect the ozone layer by eliminating the production and consumption of substances responsible for ozone depletion.

While various timelines were set for the reduction and eventual cessation of Halon use, the most significant marker for the end of Halon production and availability was indeed in 1993. This aligns with the international agreements and regulations enacted following the Montreal Protocol, which resulted in measures to phase out substances that contribute to ozone depletion.

Recognizing that Halon plays a role in fire suppression, the industry sought alternatives that are environmentally benign, leading to continued research and adoption of safer alternatives after 1993. Thus, understanding the context of environmental policies and their progression helps clarify why 1993 is notable as the end of Halon usage.
