Which item is typically described in toxicological information?

• A. Likely routes of exposure
• B. UN number
• C. Flash point
• D. Marine pollutant status

Answer: (A)

Toxicological information centers on how a chemical can affect human health and how exposure to it can occur. It explains health effects, symptoms, and the ways a substance can enter or contact the body, which helps workers understand the risks and needed protections. The item described here is the likely routes of exposure, because knowing whether a chemical can be inhaled, absorbed through the skin, or ingested directly informs safety measures and monitoring. Other items belong to different sections: the UN number relates to transport classification, the flash point concerns flammability as a physical property, and marine pollutant status deals with environmental hazard.
