- Do not release foil balloons outdoors. Power failures can result if these balloons become entangled in electric lines.
- Do not breathe helium from a balloon. Helium is not toxic nor flammable, but breathing it can result in asphyxiation (loss of consciousness due to insufficient oxygen).
- Popped latex balloons present a choking hazard for small children. Do not leave small children unaccompanied with latex balloons.
