Helium (Balloon Gas) and Helium Safety.
Balloon Gas
We often talk about using helium to inflate balloons that we want to float. However, in the UK. (I am unsure about other countries) we mostly use a product known as Balloon Gas. Balloon Gas is a re-cycled product that derives from helium that has been re-captured after being used for other purposes and is no longer suitable to be used in medical or science applications. This re-cycled helium would be wasted if not re-used in balloons.It is often speculated that helium is wasted when used for balloons.
The simple answer is no – it is not a waste. As cylinders of pure helium are filled, the escaped gas mixes with air and is captured and compressed into cylinders as balloon gas. Some manufacturers capture this helium when filling MRI scanners.
Manufacturers have stated that this wasted helium is considered a ‘recycled product’ as it would have been lost to the environment had it not been captured and re-purposed. If the balloon market demand declined, manufacturers would have to re-evaluate other markets and consider the possibilities of re-liquefying it. Re-liquefying is currently considered uneconomical from the locations of where the filling application take place.
Let’s not forget that the balloon market is only one application and makes up less than 10% of the worldwide helium market, there are several other applications that also use helium.
Helium is an inert gas, and is the second lightest element next to hydrogen. It is colourless, odourless and tasteless. INERT means it will not react to any other elements, therefore it is impossible to cause a fire or to burn. However, it is very important to know that helium is an asphyxiant, and therefore inhaling helium can cause serious harm that could result in fatality, so it is definitely not safe to inhale helium!
Is there a safer alternative to helium? This is a definite no!
Helium Safety Tips
- To avoid muscle strain and injury, use correct lifting techniques. Larger cylinders should not be lifted manually due to their weight. Cylinder trolleys should always be used.
- NEVER drag a cylinder along the ground.
- When transporting a cylinder by car or van, make sure that the vehicle is well ventilated and that the cylinder is very well secured.
- Ensure that cylinders are stored in well-ventilated areas, away from direct heat.
- When inflating a balloon, always point the balloon and inflator away from you, and close the cylinder valve after use. Some professional balloon artists will wear protective eyewear when inflating balloons. Always offer staff protective eyewear when inflating balloons.
- Always secure a cylinder to a secure support in an upright position when in use, as cylinders can cause serious injury if they fall over or roll on to you.
- Do not attempt to catch a falling cylinder; move out of the way.
- Keep cylinders away from children at all times.
- The valve on high-pressure balloon gas cylinders should never be opened unless the appropriate filling kit is attached.
- Always use the correct inflation equipment designed especially for inflating balloon and the cylinder type that you are working with and NEVER repair, alter or change equipment as this can result in serious accidents, remember you are working with gas under very high pressure.
- Slowly open the cylinder valve by turning it in an anti-clockwise direction. Listen for any obvious leaks. If there is a leak, turn off the valve, release any excess gas in the filling kit and check you have fitted the filling kit correctly.
- Remove the filling kit if moving the cylinder any distance or ceasing use. Before removing the filling kit, turn off the cylinder valve and release the pressure in the kit.
