The PHMSA Office of Hazardous Materials Safety (OHMS) issues Safety Advisory Notices to help the public understand and resolve significant safety risks.  In most situations, the advisories address safety issues that pose an imminent hazard to the public.  For example, Advisory Guidance dealing with the Transportation of Batteries and Battery-Powered Devices by Airline Passengers and Crew Members alerted the public to several recent incidents involving the short-circuiting or overheating of batteries and battery-powered devices that were improperly packed and handled aboard aircraft.  In some cases a Safety Alert will also be distributed to stakeholders.

If you have additional questions, please contact the Office of Hazardous Materials Standards at 202-366-8553.
