How to Connect a Balloon Gas Regulator:

  • Secure cylinder and open valve slightly, then close. This will clear valve of dust, water or dirt, which may be carried into the regulator and cause damage or an accident.

  • Caution: Never directly discharge of gas at any person.

  • Fit regulator and tighten connector. Do not over tighten as this will damage connector o-ring.

  • SLOWLY open similar valve to allow pressure to gradually build in the regulator. This should also prevent damage and/or injury.

  • Caution: Never lean over the regulator.

  • Note: Check connections for leaks indicated by a hissing sound.

How to Blow Up a Balloon:

  • Connect balloon inflation: place over end of nozzle and hold securely.

  • Tilt nozzle in a downward direction for gas to flow.

  • Release nozzle when balloon reaches 28cm from neck to top.

Helpful Helium Hints:

  • The recommended number of balloons obtainable from a balloon gas cylinder will be reduced if they are inflated to a diameter in excess of 28cm / 11inches.

  • Balloons will stay floating for up to 8 to 10 hours. Increased ambient temperature will reduce floating time.

  • It takes approximately one hour for one person to inflate 100 balloons.

  • Use ribbons and clips to stop gas leakage and for the best looking results.

  • Do not over-inflate.

Safety Instructions for Using Helium:

  • Do not inhale helium -- balloon gas. Balloon gas/helium does not support life. Inhaling balloon / helium can lead to suffocation or even death.

  • Cylinders must be stored below 55ºC, in a naturally ventilated areas constructed of non-combustible material with a firm level floor, away from areas of high traffic and emergency exits.

  • Read all instructions and warnings on the cylinder, cylinder tag, packaging and leaflets to ensure optimum results and your safety. If users have further questions supplier can be contacted.

  • Ensure that safe handling procedures are followed at all times.

  • Store cylinders in an upright position and secure properly to prevent toppling. Safety stands; braces, trolleys, straps and other purpose designed cylinder safety equipment can be purchased from many industry suppliers, as well as Elgas.

  • Regulators should not be attached to the cylinder during transport.

  • Cylinders must be secured during transport.

  • Always store and transport cylinders in a well-ventilated area away from obvious fire risks.

  • Do not bend and lift cylinders.

  • Use a trolley to move cylinders. 

Helium Inhalation is NO Laughing MatterDo not inhale helium

Balloons at parties are to be enjoyed but customers should be warned that an attempt to sound like a cartoon character can be fatal.

When inhaled, balloon gas displaces air in the lungs in the way similar to water when a person drowns.

Inhaling balloon gas cuts off oxygen supply to the body.

Without oxygen it only takes a few seconds before an individual can become dizzy or unconscious and can stop breathing.

Inhaling balloon gas under pressure straight from the cylinder is even more dangerous.

Air sacs in the lungs are likely to rupture and death follows almost immediately as victims literally drown in the own blood.

Elgas and the balloon industry are deeply concerned about the misuse of Balloon Gas.

Ensure that customers are advised to educate family and friends to understand the dangers and to always supervise children and teenagers. 

Don't Release Helium Balloons Outdoors

Releasing balloons may seems harmless except balloons do eventually come back down to earth and can cause environmental damage. 

Released balloons pose a danger to wildlife and especially marine wildlife.

Releasing balloons may also be illegal, depending on where you live.

For example, in NSW it is against the law to release 20 or more balloons.

Transporting Helium -- Balloon Gas

  • Whenever possible transport cylinders on open vehicles, utilities or trailers

  • If transported inside a car, ensure the windows are down.

  • If transporting cylinder in the boot, ensure that the boot is kept ajar to ensure ventilation

  • Ensure cylinders are secure in the vehicle to prevent movement

  • Ensure cylinder valve is tightly shut.

  • Remove regulators from cylinder before transporting.

  • Ensure cylinders can not be damaged by other equipment carried in vehicle.

  • Do NOT leave cylinders unattended in enclosed vehicles.

  • Do NOT use cylinders whilst still inside any vehicle

  • Do NOT hold the regulator to lift the cylinder.
