Which label indicates a corrosive substance?

• A. The Class 8 hazard label (corrosive)
• B. The Class 1 hazard label
• C. The Class 3 hazard label
• D. The Class 2 hazard label

Answer: (A)

Corrosive substances are identified by a specific hazard class on shipping labels because they can cause severe chemical burns and damage to metals. The label for that hazard is the Class 8 corrosive label, which signals handlers to take precautions such as wearing gloves and eye protection and keeping corrosives away from metals. The pictogram typically shows a liquid harming a hand and a metal surface, emphasizing the damage these materials can cause. This classification is distinct from other hazards: explosive hazards use a different symbol and meaning, gases indicate potential pressurized or reactive gas dangers, and flammable liquids warn about burning liquids. Examples of corrosives include sulfuric acid, hydrochloric acid, and sodium hydroxide, all of which can aggressively attack tissue and metal. So, the label that indicates a corrosive substance is the one associated with Class 8.
