Which hazardous material is commonly found in vehicle batteries?

Vehicle batteries typically contain sulfuric acid, which serves as the electrolyte in lead-acid batteries. This acid is essential for the chemical reactions that produce electrical energy. It is highly corrosive and poses significant risks in the event of a battery leak or failure, making it important for firefighters and emergency responders to be aware of its presence and properties when dealing with incidents involving vehicles. Understanding the hazards associated with sulfuric acid can aid in selecting appropriate personal protective equipment and implementing safety measures during response operations. The other substances listed, while dangerous in their own rights, are not commonly associated with the types of batteries used in vehicles and, therefore, are not relevant in this context.
