Co2 cylinder tank inside MRT?

If catched, ack blur

[cydaph]

like this !?

Ok, put it this way, they never put up notices saying if you are caught carrying a CO2 cylinder into the mrt, you will get fined $1k, etc etc. They also never publicly announce "No CO2 cylinders allowed on this train". If they stop you at the station and say no, then you just have to take a cab. If they call police, at most you get remanded until they confirm that it is simply CO2 and not some explosive gas. I don't think it is a crime per se. Just that if other passengers see you with a CO2 tank, may cause some panic and panic button being pushed.

I don't think it's advisable to lug the cylinder around in the MRT or elsewhere. Cab fare may cost a fair bit but saves you a lot of headache. Besides, you only pay for to and fro from the shop. No point getting stopped at the station and every kaypoh looks at you like you are a possible "bomber".

If I recall correctly, the gas cylinder is considered a dangerous object because of the pressurised gas within. So it would fall under the hazardous materials section. To be honest, we're not even supposed to bring animals or pets on board the train, like fish, hamsters, birds etc.

Jon. If you have carried it using something made for it not likely will happen.

Also I think public also know if cylinder explode due to air pressure or heat (speculation only). So I think mrt not a good idea.

Try holding it bare and go up bus. Everyone stares when I take it out lol. When they see the word Co2 they turn away.

I have personally not tried it yet, as my 5L is still going pretty strong. It's just that the ignorance of the general public and even our so-called "well-trained" transport officers irks me sometimes.

Let me get back to you on this. I distinctly do not remember CO2 canisters being listed in the hazmat section, but I could be wrong.

[Navanod]

just tell them simple terms that they (mrt staffs) can understand.

like air for fish tank / non-poisonous / non-explosive.....

bring along a big bag to avoid being too conspicuous.

I have seen bus driver asking a passenger what were those whey protein tubs. It is the size of it that attracts the attention and the potential threat or lack of knowledge of it.

I think at this point I need to point out that this line of thought is dangerous.

CO2 IS a dangerous gas in its pure form that we're using, especially in enclosed areas, like train cabins and elevators at the mrt stations. Normal air has about 0.04% CO2. Its toxic effects can be felt at 1%, starting with a drowsiness. The feeling gets progressively worse up to 5%, where carbonic acid may start forming in our airways (feels like when we choke on Coke's gas) and people may start passing out. As the gas is heavy and sinks, anyone who falls unconscious normally gets hit with an even higher concentration of CO2 near the ground and do not recover.

Under compression, it will not explode like a bomb, but if dropped or if not capped properly, the top may blow off, sending the body flying like a ram and the top like a bullet, releasing all the gas at the same time. This can cause death in a train, lift or even at home.

The chances of such things happening are very low, especially since we use very small tanks but in confined spaces and close range, a burst 2L tank can still kill. I handle CO2 tanks at work and I've seen people who open the valve without checking for leaks after connecting to a regulator.

The slow leak caused the entire valve area to ice up, preventing me from closing it. The ice then forced open the regulator, causing a very large leak. We started feeling drowsy and had to leave the room. So please be careful with CO2 during transport and installation

It is highly likely to be classified as a Hazmat, by virtue of the fact that CO2 can asphyxiate people, as what Navanod has pointed out. For safety, it is best to transport the cylinder via a car/taxi/van. There is no gain if you get stopped by the MRT staff and get fined, and the cylinder confiscated for safety reasons. Same goes with the bus. If you can ignore the weird looks then yeah, maybe bus is an alternative, but all-in-all, the trouble to use bus or MRT is just not worth the risk.

[Navanod]

I don't think it is classified by local SCDF as a hazmat Stormhawk. If it were, we would not be allowed to handle it so freely, think about all the dry ice that gets used up at weddings. Of course, the nature of CO2 gas certainly qualifies it as a Hazmat but don't think SCDF had time for it. Heh

It is not on the list of controlled hazardous materials as listed by NEA's website. However, that doesn't make it legal to carry the cylinder on the public transport. Funnily enough, i googled out this pic on Stomp. http://singaporeseen.stomp.com.sg/st...52/4124/195776 Seems it already caused a small hooha there. No response from any of the authorities though. Maybe we can write in to LTA about it?

This is the link to NEA's list of Controlled Substances.

Thanks Jon! Haha, I can provide the link to my safety officer

Stomp = deepest pits of hell. Every time I go there I lose brain cells because of all the inane comments.

Thanks for clearing that up Jon. That aside, the very presence of a cylinder on the bus/MRT will get some people flustered. Better to play safe and use a cab or car to get it done, because if you get fined, it's really not worth it.

I agree with you on this. That's how I plan to do my refills. NA isn't exactly convenient for me by public transport anyways.

I prefer to do this rather than get into trouble. By the way, I've already refilled my CO2 tank @ bioplast.

Refill cost= 15s$
Taxi to Punggol to Boonkeng and Boonkeng to Punggol = 26S$

Thanks guys!

Lucky I'm 1-2 bus stop from NA.
Cab=taxi uncle stare.

Whenever I transport my CO2 tank, I cover it up in a bag and only uncover it in the shop.

I'd feel uncomfortable if someone brought something as big and industrial looking as a gas tank onboard, especially nowadays in this world. I urge everyone to be discreet in transporting their tanks. We don't need CO2 tanks to go the way of KNO3 in our hobby.

I think there is a 2 part to this problem. Carrying empty co2 cylinder to the lfs and carrying a co2 cylinder that has been top up with co2. For the 1st part, what I can forsee is that it only take one person to mishandled his empty cylinder in the train when it is accelerating or decellerating or worst, an emergency brake is applied. Should that cylinder slipped from his/her hand, there would be scores of people injured by the rolling cylinder no matter if it's a 1 litre or 5 litre, empty or full, people will get hurt.

The risk will exponentially increase with a full cylinder. 1 scenario already mentioned here is that the cylinder might launch like a rocket and hit someone. Another scenario to think about is when the train is packed with commuter and the cylinder some how rather unexpectedly fail and all the co2 escaped into the train compartment while the train is moving. The few person nearest that cylinder could passed out ( can't verify this, just guesstimate ) and caused the few around those who passed out to lose their balance and fall while the train is moving.

My recommendation is to lessen the trip to the lfs for the co2 top up run. Having 1 or 2 extra cylinder might lessen the trip to a once a year pilgrimage on a proper transport like a taxi. You would have time to have the funds ready for this trip to and fro. Employing a bag plus a foldable trolley should help ease your burden, you don't want your body to sustain any injury while transporting 2 cylinder. Believe me, a back injury can seriously limit your lifestyle.

Hope this helps!

BFG. I agree with you on the co2 tank shooting part. Actually, I once thought of sewing a carry case from yoga mat or similar. But alas I lack the sewing talent.

This actually was cause the bus braking suddenly causing a small knock. It's quite scary if you holding it in a bag and it knocks metal. The 1st thing was look inside and try hear for obvious leaks.

[yschua]

i've carried before from yishun to commonwealth.. no one asked anything and the mrt guy even smile seeing me carry such big tank when tapping my card..
