Proper storage of helium tanks is important for safety, longevity, and maintaining the tank’s functionality. Here’s how you can properly store helium tanks:
1. Keep the Tank Upright
- Positioning: Always store helium tanks upright in a vertical position. This is essential to prevent the gas from leaking and to ensure the valve is correctly positioned for safe operation. Storing the tank horizontally can cause the valve to malfunction or leak.
2. Store in a Cool, Dry Place
- Temperature: Keep helium tanks in a cool environment, ideally between 4°C (40°F) and 38°C (100°F). Avoid high heat or direct sunlight, as extreme temperatures can increase pressure inside the tank, potentially leading to dangerous situations.
- Avoid Freezing: Helium should not be stored in freezing conditions, as extreme cold could affect the pressure inside the tank or cause malfunctioning of the valve.
3. Ensure Proper Ventilation
- Well-Ventilated Area: Store helium tanks in an area that is well-ventilated. Helium is a non-toxic gas, but if a leak occurs in an enclosed space, the oxygen levels could be displaced, creating a hazardous environment. Ensure the storage area has enough airflow to prevent the accumulation of gas in case of a leak.
- Away from Ignition Sources: While helium is non-flammable, if the tank is used in an area with other gases, keep it away from sources of ignition such as flames, sparks, or electrical equipment.
4. Keep Away from Flammable Materials
- Separation from Flammable Substances: Store the tank away from chemicals or other flammable materials. Although helium itself is inert and non-combustible, other gases or materials near the tank could pose a danger if there’s a leak or malfunction.
5. Secure the Tank
- Tank Stability: Make sure the helium tank is secured and cannot fall over. Tanks can be very heavy, and if they fall, they could potentially cause injury or damage. Use straps or other securing mechanisms to keep the tank in place, especially if it’s stored in a high-traffic area.
- Properly Lock the Valve: Ensure the valve is closed tightly when not in use. This minimizes the risk of slow leaks and ensures the gas stays inside the tank.
6. Store Away from Heavy Traffic or High-Risk Areas
- No High-Risk Zones: Avoid storing helium tanks in areas with high traffic, in corners where they might be bumped, or in places where they could be exposed to impacts or falls.
- Safe Distance from Corners or Doorways: Try not to store tanks in places like doorways, hallways, or spots where people might accidentally knock into them.
7. Avoid Storing Helium Tanks in Vehicles for Long Periods
- In Vehicles: Never leave a helium tank in a hot car or enclosed vehicle for extended periods. The extreme heat can cause pressure to build up in the tank, potentially causing an unsafe situation. If you transport a tank, make sure the vehicle is well-ventilated and that the tank is secured and upright.
8. Inspect for Leaks and Damage
- Regular Checks: Before storing the helium tank, check it for visible signs of damage or corrosion. Leaks should be addressed immediately to prevent hazards.
- Pressure Monitoring: Ensure the helium tank’s pressure gauge is in good working condition so you can monitor the tank’s gas level.
9. Avoid Storing Near Electrical Equipment or Sparks
- While helium is non-flammable, it's best practice to store the tanks away from electrical equipment or sources of sparks, just as a precautionary measure.
10. Follow Manufacturer Guidelines
- Always check the manufacturer's instructions for any specific storage or handling guidelines that may apply to your specific helium tank model.
In Short:
- Upright storage
- Cool, dry, and well-ventilated area
- Keep away from flammable materials
- Secure the tank to prevent falls
- Avoid storing tanks in vehicles for extended periods
- Regularly inspect the tank for damage or leaks
By following these guidelines, you can ensure that helium tanks are stored safely, minimising the risk of accidents and ensuring the tank remains in good condition for future use.
