WASHINGTON – Today, the U. S. Environmental protection Agency (EPA) released for public comment and peer review a draft risk assessment for 1-Bromopropane (1-BP) used in spray adhesives, dry cleaning (including spot cleaners) applications, and degreasing uses.

“This draft assessment will provide workers and consumers with critical information about the risks associated with using 1-BP in these applications,” said Jim Jones assistant administrator for the office of chemical safety and pollution prevention. “Public and scientific peer review is an integral piece to ensure we use the best available science in evaluating this chemical.”

The draft assessment of 1-BP, also known as n-propyl bromide, was conducted as part of EPA’s Toxic Substances Control Act (TSCA) Chemical Work Plan assessment effort. The chemical showed acute risks to women of childbearing age from adverse developmental effects. Other non-cancer and cancer health risks were identified for workers with repeated and chronic exposures, including neurotoxicity, kidney, liver, and reproductive toxicity, and lung cancer.

In addition to EPA’s assessment, the National Institute of Occupational Safety and Health (NIOSH) has issued a draft criteria document for worker exposure to 1-BP, and the Agency for Toxic Substances and Disease Registry (ATSDR) examined the hazards of 1-BP associated with different exposure durations. While each agency’s review has a distinct focus based on their mandates, they draw similar conclusions about the health hazards of 1-BP. The EPA, NIOSH, and ATSDR will continue to coordinate in addressing concerns associated with this chemical.

EPA recommends the public carefully follow product label directions and take precautions that can reduce exposures, such as using the product outside or in an extremely well ventilated area and wearing appropriate protective equipment to reduce exposure, particularly inhalation.

As EPA continues to support much needed reform of the nation’s chemicals management legislation, it continues to evaluate chemicals that may pose risks.

EPA is seeking public comment of this draft assessment for 60 days. The document is available at:
www.regulations.gov docket number: EPA-HQ-OPPT-2015-0084 and will be peer reviewed by the EPA’s Chemical Safety Advisory Committee (CSAC) in the spring of 2016.
