New data centers and those that undergo significant refurbishment are directed by the 1987 Montreal Protocol to use halon alternatives because of ozone-depleting properties of halon .
The new class of clean agents is designed to provide the performance of halon without the environmental side effects.
Oh, and halon was banned for environmental reasons, not because it smothers people.
However, halons were found to harm the ozone layer and, under the Montreal Protocol of 1987 (which the United States signed on to), developed countries were required to phase out production of those gaseous agents by 1994.
The protocol restricts the manufacture and use of human-made, ozone-depleting compounds, such as chlorofluorocarbons and halons .
