Ensuring the safe use of gas cylinders is particularly crucial in environments such as homes, laboratories, restaurants, and industries. Compressed gas cylinders, if mishandled, can lead to catastrophic consequences, including leaks, ruptures, and explosions.
According to Bassey Essien, former Executive Secretary of the Nigerian Association of Liquefied Petroleum Gas (NALPG), expired and faulty cylinders, along with undetected leaks, are major contributors to gas cylinder explosions.
“Cylinders have a lifespan of 15 years and require maintenance every five years. This maintenance, called re-qualification, ensures their safety. After 15 years, cylinders must be removed from circulation, as their structural integrity diminishes, posing significant risks,” Essien explained.
Additionally, faulty valves and small rubber seals within cylinders can lead to gas leaks. Essien emphasized regular checks, noting, “A simple soapy water test can help detect leaks—bubbles indicate areas requiring immediate attention.”
Low-quality fabricated cylinders, often made by unqualified welders, pose severe risks. Ensure cylinders are certified and meet the standards specified by the Nigerian Industrial Standards (NIS).
Store cylinders in cool, ventilated areas away from sunlight, stoves, or flammable materials. Avoid dropping or tampering with cylinders, as this can damage valves and lead to uncontrolled gas release.
Always use regulators, hoses, and fittings designed for the specific gas type. Ensure all fittings are securely connected and periodically inspected for wear and tear.
Do not overfill cylinders. For instance, a 6kg cylinder should only hold a maximum of 5.5kg to prevent over-pressurisation, advised Ken Balogun, Operations Manager at Solid Ventures.
Felix Ekundayo, Chairman of the Safety and Technical Committee of the Nigeria Liquefied and Compressed Gases Association, cautioned against opening the gas flow before igniting a fire. This practice could lead to an uncontrolled release of fuel, potentially triggering an explosion.
If a leak is suspected, immediately turn off the cylinder valve and open windows for ventilation. Avoid switching on lights or using open flames, as these can ignite gas vapors. Leading LPG companies recommend performing a “sniff test” around connections before turning on electrical appliances.
Chijioke Iremeka, a safety advocate, highlighted the need for public education on safe gas usage. From regular inspections to proper storage and handling, these practices can significantly reduce the risks associated with gas cylinders.
By following these guidelines, individuals and businesses can ensure safer environments, protecting lives and property.
