8 essential safety tips to prevent gas cylinder damage and explosions

A little caution can go a long way in preventing disasters. Incorporating safety practices into everyday activities can protect lives and property. Gas cylinders, commonly used in homes, industries, and restaurants, contain high-pressure gases that can become hazardous if not properly handled or maintained. Here are eight comprehensive safety precautions to reduce the risks of damage and explosions:

1. Avoid Using Fabricated Cylinders

Always purchase gas cylinders from certified manufacturers. Some fabricators use substandard metals that cannot withstand the required pressure, making them prone to leaks or explosions. Discard damaged cylinders or consult certified professionals for proper handling.

2. Regular Maintenance and Inspection

Gas cylinders have a lifespan of 15 years, with mandatory requalification every five years. This process involves inspecting and maintaining the cylinder’s structural integrity. Expired cylinders lose strength, increasing the risk of accidents. Replace or requalify old cylinders promptly.

3. Prevent Faulty Connections and Heat Exposure

Ensure all connections are secure and free from leaks. Faulty connections can allow gas to escape, leading to dangerous accumulations. Additionally, store cylinders in a cool, well-ventilated area away from heat sources, direct sunlight, and flammable materials. This prevents excessive pressure buildup.

4. Use Compatible Equipment

Always use regulators, hoses, and fittings designed for the specific gas type in your cylinder. This minimizes the chances of leaks and ensures safe pressure regulation. Check for wear and tear on equipment and replace them as needed.

5. Light Gas Correctly

For burners without automatic ignition, never release gas before lighting a flame. Accumulated gas in the air can lead to uncontrollable fires or explosions. Always light a match or spark first, then turn on the gas flow.

6. Avoid Overfilling Cylinders

Never exceed the manufacturer’s recommended filling capacity. Overpressurising cylinders can weaken their structure and increase the risk of rupture. For example, a 6kg cylinder should ideally be filled with 5kg of gas or at most 5.5kg.

7. Respond Quickly to Leaks

If you suspect a gas leak:

• Immediately turn off the cylinder valve.
• Open windows for ventilation.
• Avoid using electrical switches, lighters, matches, or cigarettes, as these can ignite leaked gas.
• Perform a quick sniff test for leaks or apply soapy water to detect bubbles around the valve or connections.

8. Avoid Using Electrical Appliances Near Cylinders

Keep gas cylinders away from electrical appliances to prevent accidental sparks that can ignite leaking gas. Appliances like refrigerators, stoves, and microwaves should be positioned at a safe distance from the cylinder storage area.
