Gas Cylinders in the Sun: How Dangerous Is It?

Gas Cylinders in the Sun – What You Need to Know

You may have noticed that gas cylinders at your retailer—for example, at a home improvement store—are generally stored outdoors andwithout any sun protection. Sunlight and high temperatures do not harm gas cylinders. Various safety precautions are in place to ensure this.

• First things first: As long as the gas cylinder is in good condition and not damaged , the sun or high temperatures pose no danger .
• Gas cylinders are usually only about 80 percent full. This gives the gas enough space to expand inside the cylinder when heated without causing any problems.
• If the 20 percent reserve were not sufficient, a pressure relief valve ensures that the gas can escape.
• However, the increased internal pressure does not cause the gas cylinder to burst. Although the pressure rises as the temperature increases, gas cylinders are designed to withstand at least 50 bar .
• At 40 degrees, the pressure in a butane gas cylinder rises to four bar. Propane expands slightly more. However, even here, at 40 degrees, the pressure reaches just 14 bar .

What to Keep in Mind When Handling Glass Cylinders

Gas cylinders are fundamentally designed to withstand a great deal. However, you should follow a few rules when handling and storing gas cylinders.

• Tighten the gas cylinder cap securely after each use. Never leave it even slightly open. The risk of explosion would be extremely high.
• Also make sure that the hoses are empty. Check them regularly for leaks, as well as the cap and the valves.
• Important: If you suspect a leak, it’s best to have a plumber inspect the hoses and valves for a small fee.
• If you’re uncomfortable leaving the gas cylinder in direct sunlight, find a shady spot for it. A gas cylinder cover might also be a good option.
