In the United States, automotive batteries are generally categorized under Hazard Class 8 (Corrosive Materials) based on the Department of Transportation’s (DOT) Hazardous Materials Regulations (HMR).

Automotive batteries are typically classified as hazardous materials due to their potential to release corrosive substances, such as sulfuric acid, and contain heavy metals, such as lead and lead compounds

The electrolyte in automotive batteries is usually a corrosive substance, such as sulfuric acid, which can cause damage to living tissues upon contact. Therefore, these batteries are considered hazardous due to their corrosive nature.

However, it’s worth noting that specific regulations and classifications may vary depending on the country or jurisdiction. If you require more specific information about regulations in a particular region, please let me know.

What is a hazardous materials under Class 8 – Corrosive substances

Under Class 8 – Corrosive substances, the United Nations (UN) classification system identifies hazardous materials that have corrosive properties. Corrosive substances are defined as substances that can cause visible destruction or irreversible alterations in living tissue, or other materials, by chemical action at the site of contact.

Examples of hazardous materials classified under Class 8 include:

  1. Sulfuric acid
  2. Hydrochloric acid
  3. Nitric acid
  4. Phosphoric acid
  5. Sodium hydroxide (caustic soda)
  6. Potassium hydroxide
  7. Ammonium hydroxide
  8. Sodium hypochlorite (bleach)
  9. Acetic acid
  10. Battery acid (typically sulfuric acid-based)

These substances have the potential to cause severe burns, skin damage, eye damage, and corrosion to metals. They require careful handling, storage, and transport to ensure the safety of individuals and the environment.

It’s important to follow the appropriate safety protocols, use proper personal protective equipment (PPE), and comply with the relevant regulations when dealing with corrosive substances.
