Toxicologists use the term "poison exposure" instead of "poisoning" to refer to an incident involving a person who swallows or comes in contact with a substance that might be poisonous. Contact could be swallowing, splashed in the eyes or on the skin, breathed in, or injected. Often the substance isn't as toxic as one initially thinks it might be, or the amount taken is so low that no bad effect is expected. Since symptoms may not develop, technically these exposures can't be called "poisonings".
