Explain briefly the first aid measure that should be taken incase of poisoning

How you treat someone who may have been poisoned depends on:

The person's symptoms

The person's age

Whether you know the type and amount of the substance that caused poisoning

If you are concerned about possible poisoning, call Poison Help at 800-222-1222 in the United States or your regional poison control center. Poison control centers are excellent resources for poisoning information and, in many situations, may advise that in-home observation is all that's needed.
