Ingestion of a small amount is not a serious problem, but inhaling the propellants and solvents from the can or spraying the aerosol near the eyes can cause injury. Use spray snow according to directions and in properly ventilated areas. Icicles and tinsel are made of plastic, tin or lead. If small pieces are swallowed, they can obstruct breathing but do not pose a serious poison danger. Try to avoid using tinsel on parts of the tree that a child can reach.
Batteries can be hazardous if bitten or swallowed.
The alkaline contents can leak from the battery and cause a chemical burn to the mouth, lips and tongue. Swallowed batteries can obstruct the airway or esophagus. Even the small disc or button shaped batteries can be dangerous. Do not leave batteries in reach of small children. Ribbons and wrapping paper can be attractive to children and pets.
