June 8, 2007—Through its Significant New Alternatives Policy (SNAP) Program, the US Environmental Protection Agency (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.
According to EPA, nPB causes reproductive and neurological toxicity at elevated exposure levels. The SNAP Program reviews ozone-depleting chemicals and determines acceptable alternatives. In aerosol solvents and adhesive end-uses, other alternatives to nPB are readily available that do not damage stratospheric ozone and pose less risk overall to human health and the environment, explains EPA.
