What does a biohazard label indicate?

• A. Chemical risk
• B. Biological risk from infectious materials
• C. Radiation risk
• D. Physical hazard like spinning equipment

Answer: (B)

A biohazard label signals a biological risk from infectious materials. It alerts you that the item or area may contain organisms or biological substances that could cause disease, so you should handle it with appropriate precautions. This includes using suitable PPE, working in containment when needed, and following proper decontamination and waste-disposal procedures. The label is specifically about biological danger, not chemicals or radiation, and not about physical mechanical hazards like moving machinery. When you see it, treat the material as potentially infectious and apply the appropriate biosafety measures to protect yourself and others.
