Although cleared under Australian safety standards, helium tanks can still be dangerous if not used or stored properly. Helium tanks are pressurised so it’s important to never expose your helium tank to extreme heat (over 54 degrees celsius), and never use a tank that may be damaged. If you suspect damage, under no circumstances should you ever attempt to repair your helium tank. When inflating balloons, always point the balloon and inflator nozzle away from your body (and the bodies of others). Wear protective goggles while operating, and remember to close the cylinder valve tightly after use. We’ve all seen someone inhale a helium balloon and talk in a squeaky voice but this is not recommended under any circumstances. Inhalation of high concentrations of helium may cause asphyxiation. You should also keep helium tanks away from children at all times.
