Which symbol is associated with Biohazardous/Infectious?

• A. Radioactive
• B. Harmful or Fatal
• C. Biohazardous/Infectious
• D. Corrosive

Answer: (C)

Recognizing hazard pictograms is about knowing what each symbol warns you about. The symbol for biohazardous or infectious materials is the Biohazard emblem, a circular design made of three interlocking crescents around a central circle. It signals the presence of biological hazards such as pathogens or infectious materials, so you know to use proper biosafety practices like appropriate PPE, containment, and careful disposal. The other symbols correspond to different risks: the radioactive symbol is a three-lobed trefoil that marks radioactive materials; the corrosive symbol shows damage to skin or metals and is used for substances that can corrode; and the toxic or harmful symbol often uses a skull and crossbones to indicate substances that are poisonous or fatal if inhaled, ingested, or absorbed.
