• Keep batteries out of the reach of children.
• Discard batteries very carefully.
• Never allow children to play with batteries.
• Never change batteries in front of children.
• Never put batteries in your mouth for any reason, as they are slippery
and easy to swallow by accident.
• Always check medication before swallowing, as batteries have been
confused as medications.
In the event a battery is swallowed call:
The National Button Battery Ingestion Hotline
(202) 625-3333 for counsel or treatment
