Poisoning
According to the Mayo Clinic:
Poisoning is injury or death due to swallowing, inhaling, touching, or injecting various drugs, chemicals, venoms, or gases. Many substances — such as drugs and carbon monoxide — are poisonous only in higher concentrations or dosages. And others — such as cleaners — are dangerous only if ingested. Children are particularly sensitive to even small amounts of certain drugs and chemicals.
Swallowed Poison
Gently wipe out the mouth and give a small amount of water.
Do not make the person vomit by putting a finger in their throat or giving them a home remedy.
Poison on the Skin
Remove contaminated clothing and jewelery. Rinse the skin with lukewarm (not hot) water for 10 minutes. ​
Poison in the Eye
Flush the eye with lukewarm (not hot) water poured from a large glass 2-3 inches from the eye, or from a faucet. Continue flushign the eye for 15 minutes, with the person blinking as much as possible. Do not force the eyelid open.
Inhaled Poison
