Canada has proposed to classify the non-FR chemical 1-bromopropane (nPB) persistent, health and environment risk. 1-bromopropane is principally used as a solvent, degreaser or intermediate in chemicals production, adhesives and sealants, not as a flame retardant. The Canada Government’s published draft assessment of 1-bromopropane proposes to classify the substance as health and environment risk (section 64 of CEPA, the Canadian Environmental Protection Act) because of developmental toxicity risk related to use in silicone mold release sprays, electronic cleaners and automotive A/C flush, that is uses not related to flame retardancy. The draft assessment concludes that three other alkyl halides do not meet CEPA $64 criteria (bromoethane, chloroethane, trans-1,2-dichloroethene). The draft assessment is open to public comment for 60 days from 5th march 2022.
