Which symbol is identified as Harmful or Fatal?

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

Answer: (A)

The symbol that signals Harmful or Fatal toxicity is the skull-and-crossbones pictogram. This mark is used to indicate acute toxicity: exposure through ingestion, inhalation, or skin contact can cause serious health effects or death, even in small amounts. That’s why it’s labeled as dangerous or fatal, and it tells you to take strong precautions—avoid exposure, use appropriate PPE, work in a controlled environment, and follow handling protocols closely. Other symbols point to different hazards. The biohazard symbol warns of infectious materials, corrosion shows substances that can burn skin or corrode metals, and the explosion symbol warns of materials that can detonate. These convey different risks, not the immediate fatal toxicity indicated by the skull-and-crossbones.
