Question: 1 / 20

Production of Halon 1211 and Halon 1301 ceased in what year?

1990

1992

1994

The production of Halon 1211 and Halon 1301 ceased in 1994 due to their adverse effects on the ozone layer. These chemicals, once widely used in fire extinguishers, are considered ozone-depleting substances. The decision to stop production was part of a broader international commitment to reduce substances harmful to the ozone layer, formalized in the Montreal Protocol. This agreement aimed to phase out the use of these chemicals to preserve environmental integrity. By 1994, the regulations and awareness surrounding ozone depletion led to a significant decrease in the use of Halon and similar substances, marking the end of their production. This is why 1994 is the correct answer.

1996
