Helium Cylinder Safety: Storage, Transport, and Important Safety Facts

Helium is a non-flammable, non-toxic gas commonly used in various industries and recreational activities. However, it is stored under high pressure in cylinders, and improper handling can pose significant risks. This guide provides essential information on the safe storage, transportation, and handling of helium cylinders, as well as important safety facts about helium.

Storage of Helium Cylinders

Proper storage of helium cylinders is crucial to prevent accidents and ensure the longevity of the cylinders. Follow these guidelines for safe storage:

Storage Location:

  - Store cylinders in a well-ventilated, dry, and cool area away from direct sunlight and heat sources.

  - Keep cylinders in an upright position and secure them to prevent tipping or falling. Use chains, straps, or racks specifically designed for this purpose.

  - Ensure the storage area is away from flammable materials and away from areas where the temperature might exceed 52°C (125°F).

  - Store cylinders away from areas where they could be knocked over or damaged.

Storage:

  - Store full cylinders separately from empty ones. This helps prevent confusion and ensures that you always have a clear understanding of your inventory.

  - Do not store cylinders near exits, stairways, or in hallways to ensure clear evacuation routes in case of an emergency.

Transportation of Helium Cylinders

Transporting helium cylinders requires careful planning and adherence to safety regulations:

Vehicle Preparation:

  - Ensure the vehicle used for transportation is well-ventilated, keep windows open when transporting by car.

  - Secure cylinders upright if possible the vehicle using proper restraints to prevent movement during transport.

- Cylinders should be unloaded as soon as possible and never left in a vehicle unattended.

Handling During Transport:

  - Avoid dropping cylinders or subjecting them to rough handling. Cylinders should be carefully loaded and unloaded using appropriate equipment.

  - Never transport with filling equipment attached.

  - Should an accident occur and a fire breaks out, inform the emergency services as soon as possible that you have a highly pressurised gas cylinder un your vehicle.

Handling of Helium Cylinders

Safe handling practices are essential to prevent accidents during the use of helium cylinders:

  - Wear appropriate PPE, including gloves and safety goggles, when handling helium cylinders.

Valve Operation:

  - Open cylinder valves slowly to avoid sudden gas release. Do not use excessive force when opening or closing valves. Do not use a wrench when attaching the filling-equipment.

  - Ensure that all connections are tight and free from leaks before use. Use soapy water to check for leaks if necessary.

Cylinder Movement:

  - Use appropriate equipment, such as cylinder carts, to move cylinders. Do not drag, slide, or roll cylinders.

  - Never lift a cylinder by its cap or valve; always use proper lifting techniques.

After Use:

  - Close the cylinder valve, remove any attached equipment, when the cylinder is not in use.

Helium Safety Facts

Understanding the properties and potential hazards of helium is important for safe use:

Non-Flammability:

  Helium is non-flammable and non-reactive, making it relatively safe compared to other gases.

Asphyxiation Risk:

  - Helium is an asphyxiant, meaning it can displace oxygen in the air. In confined spaces, this can lead to oxygen deprivation, causing dizziness, unconsciousness, or even death.

  - Never inhale helium from a balloon or a cylinder, as it can cause a lack of oxygen to the brain and result in serious injury or death.

Pressure Hazards:

  - Helium is stored under high pressure. A damaged or improperly handled cylinder can turn into a projectile if the valve is broken or compromised.

  - Always handle cylinders with care and respect the high pressure they contain.

Emergency Procedures

In the event of an emergency involving helium cylinders, follow these procedures:

Gas Leak:

  - If you suspect a helium leak, evacuate the area immediately and ventilate the space.

  - Contact emergency services and follow their instructions. Do not attempt to fix a leak without proper training.

Fire:

  - While helium is non-flammable, in the event of a fire, move cylinders away from the fire if it can be done safely. Otherwise, evacuate the area and let the fire department handle the situation.

Cylinder Damage:

  - If a cylinder is damaged or leaking, do not attempt to move it. Evacuate the area and contact emergency services.
