Safety tips for liquefied gas cylinders

Flammability, the double-edged sword of LPG

The flammability of LPG, which provides us with the great benefit of abundant heat and energy, can sometimes also bring risks and damages. This characteristic acts like a double-edged sword; on the one hand, it is a useful and efficient source of energy, and on the other hand, if safety precautions are not observed, it can lead to serious incidents such as explosions and fires. For this reason, following the safety precautions for liquefied gas cylinders is of utmost importance. In this article, for easier access to information, we have divided the safety precautions for liquefied gas cylinders into different sections so that you can easily find the information you need.

Safety Precautions for Liquefied Gas Cylinders: From Transport to Usage

Transport and Handling

• Liquefied gas cylinders should always be transported in an upright position to prevent liquid or gas leakage and to avoid damage to the cylinder valve.
• For short-distance movement, use the handle of the cylinder only and do not carry it by the regulator or valve.
• If transporting by car, secure the cylinder firmly in place to prevent it from tipping over.
• When transporting cylinders in a car, avoid placing them in hot areas such as the trunk in summer or under direct sunlight.
• Any impact can damage the cylinder or valve, increasing the risk of leaks or explosion.
• Full and empty cylinders should be transported and stored separately.

Storage

• Cylinders should be stored in well-ventilated areas to prevent gas buildup in case of a leak.
• Always store cylinders upright to avoid gas leakage.
• Periodically inspect cylinders and their connections for leaks; use a soap solution for this check.
• Keep gas cylinders away from any flames, sparks, or heat sources to minimize explosion risks.
• Avoid exposing cylinders to direct sunlight, as it can increase internal pressure.
• Store full and empty cylinders separately.
• When not in use, ensure the valve is covered with a protective cap to prevent damage.
• Store cylinders away from moisture and corrosive environments to prevent rust and corrosion.
• Only use gas cylinders that meet safety standards, and avoid using old or damaged cylinders.

During Use

• Place the cylinder outdoors or in a well-ventilated area. Avoid using it in enclosed or small spaces with insufficient ventilation.
• Before use, check the hose and gas valve connections with soap and water to ensure there are no gas leaks.
• Make sure the gas hose is securely and tightly connected to both the cylinder valve and the gas appliance. Any loose connections could result in a gas leak.
• Turn off all gas appliances before slowly opening the cylinder valve to control gas pressure and prevent sudden gas release.
• After finishing, always turn off the gas appliance first, then close the cylinder valve to prevent gas leaks.
• Always have a fire extinguisher or firefighting equipment nearby when using a gas cylinder to quickly respond to any fire incidents.

How to Detect and Fix a Gas Cylinder Leak

One of the most important safety precautions for liquefied gas cylinders is to regularly check for leaks. A simple and effective way to do this is by using a soap solution. After preparing the solution, ensure that the area is well-ventilated to prevent gas buildup in case of a leak. Also, make sure the cylinder valve is fully closed before starting.

Using a sponge or small brush, apply the soap solution to all cylinder connections, such as the hose-to-valve connection, the main valve, and other related parts. Ensure all areas where leaks might occur are thoroughly covered with the soap solution.

Once the soap solution is applied, slowly open the cylinder valve. Opening it gradually allows you to detect any leaks without a sudden large gas release. Carefully observe the areas where the soap solution was applied. If bubbles form or the solution rapidly inflates, it indicates a gas leak at that point.

If a leak is detected, immediately close the valve, move the cylinder to an open area, and distance yourself from it. Contact emergency services or the gas supplier for assistance. Avoid using a phone near the leaking cylinder, as it could cause a spark and potentially lead to an explosion.

What to Do If a Gas Cylinder Catches Fire

In the event of a gas cylinder fire, the first step is to remain calm. If it is safe to do so and you can reach the valve, try to close it to stop the gas flow. Afterward, immediately move away from the cylinder and contact the fire department. If you have access to powder or carbon dioxide fire extinguishers, you can use them to control the fire. Remember, never use water to extinguish the fire, as liquefied gas can react with water and potentially make the fire worse.

Prevention is Better than Cure

Safety precautions for liquefied gas cylinders must be carefully followed by both consumers and gas suppliers. Gas supply companies play a crucial role in providing high-quality, standard cylinders and should also educate consumers on proper storage, transportation, and safe usage. These companies can help prevent accidents by conducting regular inspections of cylinders and their connections, as well as responding promptly to issues like gas leaks. Therefore, close cooperation between consumers and gas suppliers is essential to ensure safety measures are followed and to prevent potential hazards.
