Which term describes a hazard that may be fatal to humans and animals?

Explanation:
A poison is a substance that can cause death or serious harm if it enters the body by ingestion, inhalation, or skin contact. Saying a hazard may be fatal fits the idea of poison, since it emphasizes the potential for death. The word toxic is broader—it means harmful in general, not necessarily immediately fatal. A sensitizer triggers allergic or immune responses, not a guaranteed fatal outcome. Flammable relates to catching fire, not lethality. So the best term for a hazard that may be fatal to humans and animals is poison.
