Be Careful Of Co2

[MarkBastard]

There was a TV report this week about cane toads and it showed cane toads being put in a black plastic bag and CO2 being pumped in to euthanase them.

Awesome, they should do that to the QLD footy team. Someone replace Lockyers oxygen bottle with a co2 bottle

A good friend of mine, Jim, was working on a job with his offsider at the steelworks in Newie in a bunded pipe trench. Suddenly the offsider, kneeling down in the trench keels over. Jim jumps in a pulls him up out of the trench and he slowly revives. Seems a CO2 line had ruptured further up and waves of the gas were flowing down the trench. Jim was lucky that he didn't bend down or he would have lost consciousness too.

I guess even outside, being in the wrong place can also be serious.

Exactly why when we get into anything even vaguely resembling a confined space, trenches and pits definitely included - its harnesses, winches, spotters and portable gas alarms etc etc and everyone involved with a working in confined spaces ticket.

More people been killed by toxic gas / lack of oxygen by going in to rescue someone, than there are get into trouble in the first place - guy #1 keels over... 2 guys rush in to help = 3 dead guys

Thomas J .. in the past, yep I have seen and done similar things, these days an incident like that would see someone out of their job pretty damn smartly.

As mentioned above, Chest Freezers with fermenters/kegs in em could actually be a bit dangerous... might be worth thinking about if you have little kids that could lean into one to get a fizzy drink or something and then be in real trouble.

Be the only chance the Cockroaches have of winning the series this year...

All fair comments, CO2 can be dangerous, especially where CO2 is a working gas like in a brewery. Or where you are working underground, in a confined space or somewhere like in a cellar.

Balanced risk is what we need to be aware of, to fill a "Normal" house hold room with CO2, bearing in mind that a house will exchange it air every couple of hours, you would need a big leak on the high pressure side of the system something like the diaphragm in the reg or the burst disc on the bottle letting go both very noticeable events.

A truckle from a leaky PRV or the like simply isn't going to get enough CO2 into the air fast enough to get you up to dangerous concentrations.

I'm dam sure I would haply pick up the 5 Kg CO2 extinguisher and let rip if the TV were to burst into flames, that's the sort of CO2 relace you would need to be dangerous in most cases.

By balanced risk I mean take sensible precautions, more Australians are killed by bee stings than sharks and snakes put together, Lightning strikes get about as many of us than the other three put together, I don't live in fear of any of them, but I wouldn't play golf in a thunder storm either.

Truth be told I wouldn't play golf period, but you get my drift
