Helium gas is widely used for inflating balloons, but proper handling, storage, and transportation of helium cylinders are essential to ensure safety. While helium is non-toxic and non-flammable, it is an asphyxiant, meaning it can displace oxygen in confined spaces, leading to unconsciousness or suffocation. Here’s everything you need to know about helium gas safety to avoid potential hazards.
Handling helium cylinders safely
- Always read and follow the safety instructions provided with the helium gas cylinder
- Ensure the cylinder is stored and used in an upright position to prevent damage to the nozzle or valve
- Never drag the cylinder on the ground; instead, use trolleys or safety stands for easy movement and stability
- Turn off the valve when not in use, even if the cylinder appears empty
- Use only high-quality, manufacturer-approved filling kits for safe gas release
- When inflating balloons, avoid overfilling, as this can cause them to burst unexpectedly
Storage precautions for helium cylinders
- Store cylinders in a well-ventilated and secure indoor area away from direct sunlight or extreme weather conditions
- Do not store cylinders in damp or wet environments, as prolonged exposure to moisture can lead to rusting or weakening of the metal, increasing the risk of rupture
- Keep helium cylinders away from combustible materials and ensure they are positioned on a flat, stable surface
- Never leave cylinders free-standing; secure them with stands or straps to prevent tipping over
- Ensure the storage area temperature does not exceed 49°C to prevent pressure buildup
Transporting helium cylinders safely
- Helium cylinders can be transported by car or other ground vehicles but are not permitted for air transport
- When transporting in a vehicle, secure the cylinder properly to prevent movement or tipping during transit
- Check for any leaks before placing the cylinder in your vehicle.
- If transporting inside a car, keep a window slightly open to allow ventilation in case of accidental gas release
- Do not leave the cylinder in the vehicle for extended periods or unattended
- Unload the cylinder as soon as possible upon reaching your destination
Why helium gas safety matters
Though helium is relatively safe compared to other gases, improper handling can pose risks. Ensuring cylinders are stored, handled, and transported correctly helps prevent accidents, injuries, and potential property damage. Whether for weddings, birthdays, engagements, or corporate events, always prioritise safety when using helium gas cylinders.
