Identify the rear symbol that indicates corrosive materials.

Identify the rear symbol that indicates corrosive materials.

• A. Yellow with flame on circle
• B. Red with flame
• C. Green with canister
• D. Black and white with liquid poured onto hands/surface

Answer: (D)

The thing being tested is recognizing hazard pictograms that show corrosive materials. A corrosive substance is one that can burn skin and eyes or corrode metals, so the symbol used has to clearly depict damage to both tissue and a material. The rear symbol described as black and white with a liquid pouring onto a hand and onto a surface is the corrosive pictogram. It communicates that contact with the chemical can cause immediate burns to skin and damage to materials, which is exactly what corrosives do. That’s why it’s the best answer for identifying corrosive materials. The other symbols indicate different hazards—not corrosive. A flame image signals flammable or combustible materials, while variations of that flame cue point to fire risk. A green canister often relates to gas or environmental concerns, not corrosion. So they don’t convey the specific corrosive danger the symbol in question does.
