This bill directs the Secretary of Transportation to promulgate a final motor vehicle standard within two years to address safety risks related to batteries in new electric and hybrid vehicles. This standard aims to mitigate unreasonable risks of fire, explosion, reignition, thermal runaway, and fire breaching the passenger compartment, among other safety concerns. The Secretary must consult with major vehicle manufacturers, fire protection experts, and organizations representing professional and volunteer firefighters and fire chiefs during this process. The minimum standard requires new electric and hybrid vehicles to be equipped with first responder access technology for timely battery fire extinguishment and technology to suppress thermal runaway if a battery cell is damaged. It also mandates safeguards to delay fire breaching the passenger compartment, allowing sufficient time for escape or rescue, and requires battery and first responder access to be in uniform, standardized locations. Furthermore, the bill requires a separate safety standard for clearly marked interior and exterior mechanical door releases on all doors and hatches to ensure safe exit in case of electrical system failure. Beyond vehicle standards, the bill mandates the Secretary to publish guidance for firefighters on responding to electric and hybrid vehicle battery fires within one year of the standard's promulgation. It also requires the Secretary of Health and Human Services to conduct a study on the health effects of these fires on first responders and submit a report to Congress within one year. This report must include findings, input from fire safety organizations, and recommendations for legislative action to protect first responders and improve battery safety.
