Final answer:
c) Corrosive materials
The symbol of Corrosion represents corrosive materials, which are substances that can cause immediate damage to tissues and materials they come into contact with, and can also be toxic.
Step-by-step explanation:
The symbol of Corrosion (Physical Hazard) represents corrosive materials. Corrosive substances are materials that can damage or destroy other substances they come into contact with through a chemical reaction.
Such substances are hazardous because they are directly harmful to tissues they touch, and can also have systemic toxic effects. Examples of corrosive substances include strong acids and bases, like hydrochloric acid, which can burn your skin and eyes and cause damage to other materials.
In the context of hazardous waste, corrosives are one of the characteristics that can qualify waste as hazardous, along with ignitability, reactivity, and toxicity.
It is important for safety in laboratories where such substances are used to follow proper safety precautions when handling them, as indicated by the corrosion hazard symbol.
