Step 1:To determine the hazard class of automotive batteries, such as those sold at Walmart, we need to consider their primary hazardous components and properties.
Automotive batteries, also known as lead-acid batteries, contain sulfuric acid and lead.
Step 2:: Identify the hazardous components
- Sulfuric acid: a strong corrosive liquid - Lead: a heavy metal that is toxic and can cause environmental damage
Step 3:: Consult the UN Numbering System for Classification of Dangerous Goods
Based on the hazardous components, we can classify automotive batteries according to the United Nations (UN) Numbering System for Classification of Dangerous Goods.
Step 4:: Determine the hazard class
Automotive batteries fall under Hazard Class 8 - Corrosives, due to the presence of sulfuric acid.
Step 5:: Identify the subsidiary risk
Since automotive batteries contain lead, they also present a risk under Hazard Class 6.1 - Toxic substances, packaged in a way that minimizes the risk of leakage during transportation.
Final Answer
Automotive batteries at Walmart are classified under Hazard Class 8 - Corrosives, with a subsidiary risk under Hazard Class 6.1 - Toxic substances.
