× The federal government has shut down due to the failures of the President and Congress to continue government funding. Millions of Californians receiving benefits from state programs may be impacted. For now, California’s Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) will continue to provide services and enroll eligible families as long as funding is available. No new federal funding to California WIC will be provided until the President and Congress take action. Families should continue to use their WIC benefits and attend their WIC appointments. This information is subject to change, so please monitor the California WIC website for updates.

Please be wary of potential highly partisan political messaging while visiting federal government websites for information related to the federal government shutdown.

HAZARD EVALUATION SYSTEM AND INFORMATION SERVICE (HESIS)

Early Warning and Prevention: 1-Bromopropane (1-BP)

1-Bromopropane (1-BP, n-propyl bromide, or nPB) is a solvent used in degreasing and spray adhesives that can cause serious health damage. We have known for some time that 1-BP harms the reproductive and nervous systems. There is now evidence from several national and international authoritative sources that it also causes cancer. Effective August 5, 2016, the State of California added 1-BP to the list of chemicals known to the state to cause cancer for purposes of Proposition 65 (Safe Drinking Water and Toxic Enforcement Act of 1986).

Based on new health effects information, HESIS selected 1-BP as the first chemical for early warning and prevention activities under our SB 193 early warning authority. HESIS developed and distributed a Health Hazard Alert on 1-Bromopropane to California businesses that purchased 1-BP, inviting them to work with us to improve protection for workers who may be exposed to this chemical.
