heres a fact: On avg something like 2 or 4 people in australia on a yearly basis kill them selves by putting a 9 Volt battery on there tongue!! yup im sure weve all done that as kids

Come on man, as a sparky you should know this is not feasible. If you're testing a 9v battery on your tongue, the current is going to take the path of least resistance, the current passes through the saliva to the other terminal on the battery - the reason you feel it is because your taste buds are highly sensitive. The current must pass through the heart to be lethal (60+mA for healthy person) eg. Getting booted on the hand and being grounded at the feet.

The internet is full of old wives tales, heresay and myths - your training should give you the answer you need if you stop and think about it.

If not, then I challenge you to find a news story where someone has died from this

mate im taking the piss!!!!!!!!! have a laugh

it was a joke that use to get pulled on us and we never forgot about it.

a tafe lecture once told us all and certain students fell for it , well we all did being first year apprentices,in the first couple weeks at tafe!!!

the point was for us to go and say that on site and turn into the laughing stocks for a week!! Hence why its something i dont forget!


no need to get scientific...

but your wrong when it comes to 60 ma will kill a healthy person. Low currents can be harmful and sometimes you feel nothing, what kills you with low current is the pulsations of your heart. When its pules(pumps) if you shock your self at the exact right time...... that can kill you. i think its some like 20 milli amps can kill some one with the pulsating in your heart.(20 milli amps is rare

Ventricular fibleration to a degree.

When I was a kid I learnt how to make a chlorine bomb, so decided I would give it a go.

So, with a couple of mates over for peer support, I mixed the two ingredients together in an old steel paint tin and stood 5m away to see what would happen.
After 2 minutes... nothing, so we figured stuff it, and put the tin back in the shed.
20 mins later my sis came running out the house asking why smoke was pouring out the whirly bird of the shed
I lifted the roller door foor the shed and this greeny yellow smoke poured out of the shed.
So I took a deep breath and ran in trying to find the paint tin, mainly so I could dispose of it before my parents found out about it.

I now know that the smoke was pure chlorine gas, and I was lucky I didnt do any damage to myself, however it did impress my mates!

That was when I decided to give up on bombs and concentrate on rockets

Thinking back, I am really lucky that I have all my fingers still

hmmmm crane op gets high on chlorine gas.......no i know why so many look the way they do hehehehehe

I was always amazed at how easy it was to get chemicals as a 15 year old.
I bought 5kg of dry ice and took it to school. That got me in trouble, I still feel sorry for that kid.......

Another time we walked into a chemical place, went up to the counter, this was the conversation:
Me: Hi, I would like some ******** ********. Can you supply that to me?
Salesguy: We can supply that to you no problems. We supply in 5mm grain, 3mm grain, or fine powder. Which one would you like?
Me: Well I want it to make rockets, so the finest powder possible please.
Mate: (Whispers) You idiot, he wont give it to you now.
Salesguy: (Sniggering) Yep the fine powder is definately the one you want then. What fuel are you going to use with it? ********** or ****** *****?
Mate: (Shocked look on face)
Me: The ***** ***** mix. I dont like the ********** mix, it can have a slightly too energetic reaction sometimes.
Salesguy: (Knowing smile) OK, our smallest bag you can buy is 5kg. That should give you about 7.5kg of rocket fuel.
Me: OK, thank you. That should keep me busy.

what about working with your drinking water??? liquid and gas chlorine, acid, sodium hydroxide, a bit dangerous. the public that sneak up on you more so

[Skuts]

I'm a sparks and work with anything from 330kv to 12 dc, a few months ago a 132kv voltage transformer decided to let go with no warning sending a large piece of 10 mill thick steel into a brick wall at the same time throwing oil that's on fire around as it exploded, nice hey don't really want to be around when that happens. Indoor switch gear also blew up about 6 months ago which would have vaporized anyone standing near again with no warning so yeah I think I have a fairly high risk job. ( not to take from others work)

Cheers

I'm a drill fitter, So fixing drill rigs.
About a month ago now had a compressor hose burst with no warning. When it burst, it sprayed hot pressurised oil over the exhaust and turbos which resulted in a huge fireball that completly lit the pit up and burned approx 60% of the rig.

One of my coleagues an hour before was around that area looking for a non-related leak and water cart driver had asked if the rig needed water 5 mins previously. had he have needed to fill the rig he would have been toast.

Im a mech fitter/process operator. When I was in sydney in a fuel refinery a few years back i was changing a PSV (pressure safety valve) on a manifold that joins 5 large crackers full of 200 decrees c+ hydrocarbon liquid/gasses. The operators in charge of the area had "isolated" the pipes we were working on but they failed to follow the line down to the last and biggest cracker that was not in the main group.

Anyway just as another fitter and I had finished putting the PSV in, they had a pressure spike in the big cracker due to overheating it and the next PSV in the line (opens at a lower pressure) popped open and released a bloody torrent of piping hot hydrocarbon gas and liquid into the air about 1m away from my head. Have never run down stairs faster in my entire life! Had ringing in my right eat for about 3 weeks. Its just lucky we had finished installing the valve, if it was still off and we were up there we probably wouldnt be here now because all that hot gas and hydrocarbon would have come out right in our faces.

Scary stuff!

[Riggers]

I'm a stage rigger, quite possibly one of the craziest jobs I have ever done..... Worked on steel construction team before starting in stage work and have been doing it for the last 6 years... We don't get the luxury of scaffolding or access to the high steel it's all about the climbing!! We've had guys out from local company's that refuse to climb coz "it's too high".....

Working on big day out a few months ago one of the guys in our crew fell off the stage roof from 8m landed on the front of the stage which flipped him over and he landed on the grass in between 2 stillages of scaffold!! He was very lucky and has been cleared for work as of a few weeks ago... It just goes to show, the one time you don't hook on and it happens as fast as that....

Biggest lift I've ever been involved with was the burswood dome pole stage, it involves a four crane lift of a 30t stage roof section.... And I thought 2 crane drivers was hard enough, try four!!!

... I'm a safety advisor .. Doesn't get much more dangerous than that when you've got retard riggers, TAs, crane drivers, sparkies, truck drivers etc to keep in line


jk jk .. *goes back to being silent on PCS*




(popped in to look for a particular post.. came across this, couldn't resist lol.. hope all have been well!)
