Compound Allowed as Alternative to Ozone-Depleting Chemicals

Through its Significant New Alternatives Policy (SNAP) Program EPA is allowing the use of n-propyl bromide, a nonflammable organic solvent, as an alternative to ozone-depleting substances in metals, electronics, and precision cleaning.

EPA is also proposing to allow the use of n-propyl bromide (nPB) in specific coatings applications and to prohibit its use in aerosol solvents and as a carrier solvent in adhesives. At elevated exposure levels, nPB causes reproductive and neurological toxicity.

The SNAP Program reviews ozone-depleting chemicals and determines acceptable alternatives. In aerosol solvents and adhesive end-uses, other alternatives are readily available that do not damage stratospheric ozone and pose less risk overall to human health and the environment. As required by the Clean Air Act, this regulation considers alternatives to ozone-depleting substances which contributes to the success of the Montreal Protocol on Substances that Deplete the Ozone Layer.
