High-pressure gas cylinders are heavy, highly pressurized, and contain concentrated elements. Mishandling them—whether in a factory warehouse or at home—can lead to catastrophic accidents. Follow these 5 cardinal rules.
1. Always Store Upright
Never lay a cylinder flat on the ground. Cylinders should be stored perfectly upright and secured with a chain or placed inside a dedicated cylinder trolley to prevent them from tipping over. A falling cylinder can easily snap its valve, turning it into a high-speed projectile.
2. Keep Away from Oil and Grease
This is crucial for Oxygen. Pure oxygen reacts violently with oils and grease, potentially causing spontaneous combustion. Never lubricate a tight valve with oil, and ensure your hands and gloves are completely grease-free before handling.
3. Distance from Heat Sources
- Keep cylinders at least 20 feet away from open flames, stoves, or welding operations (unless using the active welding gas).
- Do not store them in direct, harsh sunlight for extended periods.
4. Leave the Valve Cap On
When the cylinder is not actively in use and connected to a regulator, the protective metal or plastic valve cap must be securely screwed on. This protects the most vulnerable part of the cylinder.
5. Ensure Proper Ventilation
"A slow leak in a closed room is a silent hazard."
Store cylinders in well-ventilated areas. If a nitrogen or argon cylinder leaks in a sealed room, it displaces oxygen and can cause asphyxiation without any warning smells.
