View Full Version : gas leak that kill!

Two years ago, we read about a Singaporean family killed by leaking gas in their apartment.

Last week, an entire family of 3 were killed by the same leak in their Taiwan apartment.

Do you turn off you gas cylinder after each use and at each night before you go to sleep? If you are not, plese do.

Turning off your gas cylinder means switching off the gas pressure at the cylinder valve, leaving the gas stove depressurised and thereby containing the LPG to the cylinder. Thus minimising the risk of any leak that can cause dead.

I think their leaks came from the central gas supply. In the singapore case I believe that they did some renovations and the contractors hit a gas supply pipe without knowing it. For our homes it would be advisable to just turn if off at the head of the cylinder.

my habit is to turn off the regulator before turning off the stove. this practice paid dividend when one day the fire on the stove kept burning even after i turned off the regulator. i discovered that it was the valve at the gas tank that failed. it was at an ungodly predawn hour and i was worried that i'd lose my home to flames. so i called the bomba for advise, but got pushed around from station to station and finally was curtly told to biar saja wait for morning and get my gas supplier to look into it. without an alternative then, i had to succumb to the final advice. my supplier came and did a hair-raising heart pounding 1-minute op to replace the valve in the gas cylinder. he was cool and calm, as tho it was more than an every day job.

one advise, never open a door or enter a buidling with a naked flame (cigarette, candle, etc) if there is no guarantee that there is no gas behind the door. it has happened before, and it will happen again. people were innocent and unsuspecting, let us retian our innocence but lets be suspecting and alert at all times.

Just some tips on use of LPG gas tank.

1) Keep window open for ventilation to allow dilution of the gas leak to be diluted to below the flammable level

2) Turn off regulator after each use, especially at night

3) Carry out regular soap solution check of the gas system (hose, regulator, valves, gas tank body etc) to detect leak

4) In the morning check for gas leak (smell) before switching on any lights. The spark created by the switching on of the light will ignite the gas vapor

5) Change the hose once every two years and regulator once every 5 years

6) Carry the gas tank to the open (use hand-gloves or towel to prevent cold burn) in case of leak from the gas tank body

7) If possible, position your gas tank outside the kitchen. Particularly bad to keep the gas tank in the enclosed compartment of the cooker!

8) Have your gas dealer's phone number (or better still Oil Company's e.g. Petronas/Shell/Esso/BP/Summit's etc toll free emergency response number) on your Emergency Call Number List and this list should be displayed near your phone. This is in addition to your 999/994. I understand oil companies' emergency response numbers are manned round the clock.

Hope above will help in a small way. With regards to central system, smell (gas stenched with a rotten egg smell to tell users that a leak is taking place!), ventilation and regular checking of the piping system are some of the actions one should regularly take.

thank god my precious little apt is still intact.

i had a contractor to do some waterproofing works in my balcony kitchen over the last 5 days. as it was to be a messy job, i cleared the kitchen, including disconnecting the regulator from the gas cylinder and moving it to the indoor dry kitchen. the next night, i thought there was a dead rat or something like that under the pile of newspapers i spread out to cover my kitchen stuff. last night when i reconnected the gas, the cylinder was empty! did my nose detect something wrongly? my contractor had been lighting up liberally although i generaly impose a smoking ban indoors. perhaps, can somebody tell me, could it have been that the pile of newspapers over the gas cylinder absorbed or did something to mitigate the potency of the leaking gas? the horrifying fact cannot be changed - gas from the cylinder was discharged after i removed the regulator, and that can only speak very badly of quality and safety control. what more can i deduce when it is my second experience.
