Helium– Safety + Precautions

• Balloons filled with helium are sensitive to hot and cold temperatures and will expand or contract in extreme temperatures. • As an example, a balloon inflated in a warm room and taken outside to very cold conditions will seem to lose helium. • When the balloon is returned to indoor temperatures the balloon should return to its original state. • The opposite is true in hot weather conditions.

CAUTION Just so you know

• Helium is stored in highly pressurized cylinders ranging from 1,800–2,400 pounds per square inch (PSI). • A ruptured helium cylinder can be compared to a missile or the equivalent of two pounds of TNT. • Never use metallic ribbon on helium-filled or latex balloons. If accidentally released into the air, the ribbon could cause electrical failure if caught in power lines. • Every helium-filled balloon should have a balloon weight attached.
