On January 1st, 2018, the WSIB effectively banned the use of nPB (1-bromopropane) in Ontario workplaces when it lowered the allowable airborne concentration from 1pp to 0.1ppm. nPB made a big splash in the market when it first appeared as a non-flammable cleaner for electronics, but as more toxicity data was produced over time, the health risks of this solvent looked worse and worse. Accordingly, regulators have been continually tightening the squeeze on nPB through the years and by now there are very few large professional users. As a result, the impact of this new regulation on the overall economy will be minor, however, for companies still using nPB, the time to change processes has come.

MG Chemicals offers a variety of non-flammable cleaners that can act as nPB replacements, such as 411 HFE Solvent and the 4120 Super HFE™ Electronic Cleaner. If the nPB ban is affecting your company, contact our technical support team so we can help find a solution for your process.
