Use the LPG Gas Detector To Detect Gas Leakage

LPG is dangerous it is fire and explosion hazard


LPG Gas Detector Singapore

Liquefied Petroleum Gas (LPG) is non-toxic and non-corrosive, and it burns cleaner than gasoline or diesel and consists lesser articulates when compared to the latter. Gas leaks are typically caused by worn or damaged gas regulators or hoses. The gas leak is rarely from the gas bottle itself. The lower and upper limits of flammability are the percentages of LPG that must be present in an LPG/air mixture. Between 2.15% and 9.6% of the total LPG/air mixture must be LPG in order for it to be combustible. When it is burning properly, the flame is blue. A yellow or red flame is an indication of incomplete combustion.

Can LPG cause an explosion? LPG is heavier than air and will flow along floors, downwards into the gullies and will settle in low-lying spots, trenches or basements. At high concentrations, the gas displaces air to cause asphyxiation. When the gas meets an ignition source it can burn or explode.The cylinders can explode if involved in a fire. Be cautious to avoid direct exposure, as liquid LPG is cold enough to cause severe cold burns on exposed skin.

The benefits of using the gas piping system are:

  • Convenient as continuous gas supply is definite
  • Safe and reliable which supplies piped gas island-wide to households and businesses in Singapore.
  • Clean and hygienic which requires no additional storage space, ensuring a clean and hygienic environment at all times
  • Engage a Licensed Gas Service Worker (LGSW) for any installation or alteration of gas pipes.
  • Engage a Professional Engineer (Mechanical) to assist you with the relocation of your gas meter.

First Safety Provisions for LPG Cylinder Installations

All LPG cylinder installations (ie manifold or piping systems) and fittings in commercial or industrial premises must be approved by SCDF. All pipes penetrating the firewall or floor slab must be able to firestop appropriately. All cylinders and their ancillary fittings must be designed, fabricated and tested in accordance with the accepted code or standards.

For air-conditioned premises, an approved gas-leak detection system must be provided in the area or compartment where the internal LPG pipes and fittings are installed, with a local alarm connected to a main fire alarm panel. The system shall be linked to the exhaust fan system and the emergency shut-off valve.

For the kitchen with fixed fire suppression system, activation of the system will automatically shut off the supply of LPG to the kitchen. Easy accessibility to remote emergency shut-off valve must be made available during emergencies. All the fixed electrical equipment must be spark-proof and intrinsically safe with no ignition source nearby. Vapouriser must not install near the system or in the house.

Fixed LPG Gas Detector

The fixation of the LPG gas detector near the ground level will be ideal as the gas is heavier than air. It can detect if there is any leakage. With the advancement in technology, LPG gas detector is applied widely. It is not only used domestically, it is also used to test the air in the underground vaults, boiler rooms, sewers, commercial building, industrial plants and post-fire sites, laboratories and eating outlets.

Portable LPG Gas Detector

The portable LPG gas detector is designed to be highly sensitive and respond swiftly should there be a leakage. It is tested to ensure compliance before it is made available for consumers’ use. It is capable of detecting any leakage of any gas piping and valves. If there is no such LPG gas detector, testing for leakages will be difficult as the gas is colourless and odourless. The measured gas concentration of the gas is displayed in digitally on the screen and accurate measurement is possible. The sensor in the LPG gas detector is able to detect the gas from the low to high concentration owing to various detection principle. The digital flow sensor is able to maintain the regular flow rate. If there is a leakage of LPG, the detector will sound the alarm before the concentration of LPG reaches the lower explosive limit to allow occupants to react to the leakage. With the highly efficient pump inside, it can respond to flammable gases leakage immediately.

Advantages of LPG Gas Detector

Compared with other multi gas monitoring equipment it is considered low cost and affordable. The LPG gas detector is durable and easy to maintain as compared to other conventional gas detecting devices. Though the detector is calibrated at the factory, It is recommended that user should calibrate it before use and do it at least once a year depending on the usage.

What You can do if there is a gas leak?

  • Turn off all gas valves.
  • Do not turn on/off any switch
  • Open all the doors and windows, keep the site well-ventilated
  • Do not smoke, light cigarette lighters or light matches
  • Do not attempt to detect a gas leak with a naked flame. Put out all naked flames such as oil lamps, candles
  • Call Gas Department 24-hour Customer Services Centre


Keep the liquid containers vertical at all times. When moving, never tip, slide or roll liquid containers on their side. Liquid or gaseous containers must be secured during transport. Avoid mechanical or thermal shock. Always move liquid LPG containers by pushing, not pulling. “LPG” label include propane, butane and isobutane (i-butane), as well as a mixture of these gases.
