This bill amends the Federal Fire Prevention and Control Act of 1974 to enhance fire safety related to lithium-ion batteries. It introduces formal definitions for "lithium-ion cell or battery" and "thermal runaway," which refers to an uncontrolled increase in cell temperature caused by exothermic reactions. The legislation expands the scope of fire prevention and control activities to explicitly include the suppression of fires resulting from thermal runaway , particularly those involving lithium-ion cells or batteries. Additionally, it authorizes funding for programs specifically designed to suppress these types of fires, thereby improving firefighter readiness and capabilities in addressing such incidents.
