Calibration gas cylinders are essential for maintaining the accuracy of gas detection equipment across a range of industries - from oil and gas to environmental monitoring. To get consistent and reliable results, proper storage and handling of calibration gas is just as important as using the right gas mixture.
Why Proper Storage and Handling of Calibration Gas Cylinders Matters
Calibration gas mixtures are manufactured to precise tolerances. Exposure to extreme temperatures, moisture, or physical damage can:
- Degrade the gas mixture
- Shorten shelf life
- Cause inaccurate calibration
- Lead to compliance violations
Avoiding these risks begins with proper procedures.
Calibration Gas Cylinder Storage Best Practices
1. Keep Cylinders in a Cool, Dry, Well-Ventilated Area
Calibration gas cylinders should be stored in a protected and well-ventilated area. They should be kept at room temperature, away from heat sources, open flames, or direct sunlight. High temperatures can affect gas pressure and composition. They should be stored at least 20 feet from combustible materials.
2. Avoid Extreme Temperatures
Extremely cold or hot environments can cause regulators or valves to function improperly and potentially affect gas composition. The best temperature ranges for most calibration gases are typically 50°F to 77°F.
3. Store Calibration Gas Cylinders Upright and Secure
Use cylinder racks or holders to prevent them from falling over. Never store cylinders lying down, especially refillable ones, as it can compromise pressure regulation.
4. Separate Full and Empty Cylinders
Label and organize full and used/empty cylinders clearly to avoid confusion during calibration or disposal.
5. Check Expiration Dates
Calibration gas cylinders have a limited shelf life - usually 12 to 36 months, depending on the gas mixture. Use a first-in, first-out system and dispose of expired cylinders according to local regulations.
Calibration Gas Cylinder Handling Best Practices
1. Use the Correct Regulator
Each calibration gas mixture may require a specific pressure-demand or flow-regulated regulator. Always verify compatibility before attaching.
2. Avoid Cross-Contamination
Use dedicated regulators and tubing for each gas type. Mixing gases - even in trace amounts - can lead to inaccurate calibrations or safety hazards.
3. Close Cylinder Valves After Use
Always shut off the cylinder valve after use to prevent leaks and preserve the gas.
4. Use in Well-Ventilated Areas
Even small amounts of gas can displace oxygen or create a hazardous environment. Always use calibration gas in areas with adequate ventilation.
5. Inspect Before Each Use
Employers are required to conduct gas cylinder inspections. Check for leaks, corrosion, damaged valves, or signs of tampering. If anything looks off, don’t use the cylinder.
Disposal and Recycling
Don’t toss used calibration gas cylinders in the trash. We offer a free and easy way to return most calibration gas cylinders. Always follow local, state, and federal regulations when disposing of compressed gas cylinders.
