Gas Cylinder Safety: A Guide for Construction Professionals and Homeowners in Bali

3 min read

The use of gas cylinders for cooking and other purposes is widespread in Bali, but it’s crucial to understand the potential dangers associated with them. Ensuring safety requires diligence, proper equipment, and an awareness of common issues. This guide provides essential information for both construction professionals and homeowners on how to handle gas cylinders safely.

Understanding the Risks

In Indonesia, the transition from kerosene to LPG (liquefied petroleum gas) has led to a significant increase in gas cylinder usage. Unfortunately, this transition has also been accompanied by safety concerns, with numerous reports of fires and explosions. These incidents are often linked to substandard equipment. A study indicated that a large percentage of gas hoses, cylinder check valves, stoves, and regulators did not meet Indonesian safety standards.

It’s also important to be aware of illegal practices such as tampering with check valves and mixing other substances with gas to increase profits. Such practices can severely compromise safety.

Key Components of a Safe Gas Installation

A standard LPG gas installation includes several key components, each of which needs careful attention.

  • Gas Cylinder: Cylinders are typically made from two halves welded together, with a threaded pipe for the check valve. The 3 kg light green cylinders have been identified as having issues with poor welding, leading to leaks. It’s best to avoid the 3 kg green cylinders due to these issues. Look for excessive rust or poorly formed welds. The cylinders should ideally be made of high-strength steel, but some may be made of ordinary mild steel, making them prone to rust.
  • Check Valve: This brass valve screws into the cylinder’s neck and seals the gas. It has a pin that opens when pressed by the regulator. Faulty check valves can have badly fitting screw threads or poor seals, causing leaks. The valve should fit tightly, and its rubber seal should be inspected and replaced if necessary.
  • Regulator: The regulator reduces the high pressure of gas from the cylinder to a lower pressure for appliances. It attaches to the check valve with a pin that releases the gas flow. Faulty regulators are a common source of leaks. The regulator should be checked for hissing sounds, indicating a potential leak.
  • Gas Hose: Good-quality hoses are thick rubber with a woven canvas layer and sometimes a metal cover. Avoid thin or plastic hoses, as they can perish quickly. Check the hose regularly for cracks and replace it if any are found. It’s also advised to cut off the end of the hose before reattaching to ensure a fresh connection point.

Safety Precautions

To ensure safety when using gas cylinders, adhere to the following guidelines:

  • Ventilation: Never keep gas cylinders in enclosed spaces; they must be in well-ventilated areas, or ideally, kept outside. Avoid storing gas cylinders in cupboards under cookers, and ensure they are away from any flames.
  • Equipment Check: Regularly check all components: cylinders, regulators, hoses, and appliances. Pay attention to the condition of the welded joints and check valves. Ensure rubber seals are intact when purchasing gas cylinders.
  • Cylinder Condition: When buying gas cylinders, carefully check for rust, poor welds, and ensure the seals are intact. If possible, check the weight of cylinders to verify they are full.
  • Hose Maintenance: Inspect hoses regularly for deterioration, replacing them immediately if cracks or bulges are found. Use hose clips to secure the hose at both the regulator and appliance.
  • Leak Detection: Check for gas leaks by smelling for gas, listening for hissing noises, or using soapy water to identify bubbles.
  • Certification: Look for the SNI (Indonesian National Standard) marking on cylinders or product packaging, but be aware that these can be faked.

Additional Considerations

  • Training: If you have staff who handle gas cylinders, ensure they receive proper training. This could include providing clear instructions on how to change gas cylinders.
  • Private Operations: Be aware of private distributors who might tamper with check valves or mix other substances with the gas.
  • Substandard Equipment: Avoid using the green 3kg gas cylinders and associated equipment due to their known quality issues.

By adhering to these guidelines, construction professionals and homeowners can significantly reduce the risks associated with gas cylinder use, creating a safer environment for everyone.

This is also important in construction settings where safety should always be a top priority.
