Since that act only applies to people at work ( or those affected by such work) and the people blowing stuff up are not "at work" as defined in the act, the regulations don't apply. So, what you are saying is that balloons wouldn't be a pressure vessel if they were part of someone's occupation. Well, nobody said they were. So, not only were your comments irrelevant, they were also technically wrong. HSE also does not regulate children playing conkers. Link to comment Share on other sites More sharing options...

So the official EU wide definition of pressure vessels is irrelevant as to discounting a balloon as a pressure vessel. Well I disagree. Balloons are not pressure vessels, either when utilised in work environments or otherwise. BTW the official HSE position on conkers appears to be http://www.hse.gov.uk/myth/september.htm.

John Cuthber Posted October 28, 2018 Share Posted October 28, 2018 (edited) An inflated balloon is a vessel, and is under pressure. It is a pressure vessel. It falls outside the scope of the regulations for our discussion here because it is not work related. If you were using one at work (and you might- for example to store low pressure gas in a lab) then it would fall outside the regs because the pressure is (usually) too low. 19 minutes ago, louis wu said: So the official EU wide definition of pressure vessels is irrelevant as to discounting a balloon as a pressure vessel. Well I disagree. Your agreement or otherwise is subordinate to the evidence which shows that balloons are vessels under pressure. HSE has a view on kids playing conkers.

hypervalent_iodine Posted October 29, 2018 Share Posted October 29, 2018 ! Moderator Note I am extremely unimpressed by the conduct in this thread. rangerx, Raider5678, TenOz, J. C. MacSwell, you have all been here long enough to know that we expect you to stay on topic. This thread is not about the recent pipe bomb incident in the US. Do not continue to drag it off topic. rangerx and Radier5678, you have had enough run-ins to know that we don't tolerate hostility. You are both guilty of not complying with that to different extents. Raider, you by far are the worst in this case. We do not allow members to insult others. We do not allow them to attack their mental health. And if your best response to something is 'fuck off,' then I suggest not posting since you clearly have nothing of value to contribute.

nevim Posted October 29, 2018 Share Posted October 29, 2018 (edited) ,It is SO EASY to make a bomb. I could make one right here, right now. But I can't think of any reason why I would do that, right now, or anytime. Unfortunately, some people can.

I've made "bombs" with dry ice, water and a soda bottle; carbide, water and a milk jug; sparklers, duct tape, and a match. Cost me about $1 and two minutes of my time. My kids told me how to make the sparkler bomb. Link to comment Share on other sites More sharing options...

This discussion was intended to be about dangerous, life-threatening devices. Why would anyone care about harmless devices that go "pop"?

Believe it or not, several of these bombs that go "pop" could be life threatening. A sparkler bomb properly hooked up could have killed someone just as effectively as the pipe bombs sent, if not better.

I'm an industrial chemist... I just know some things. I usually assume I know less than I think I do... maybe I know more than I think I do when it comes to poisons, explosives and drugs - I don't know. You can't get through a chemistry education without knowing/learning some things. Regarding the nitrating... I think I might have been told that at school. ... also - that's how you get TNT from toluene, no? There are other energetics that are also nitrated as far as I am aware. Not something I am interested in playing with anyway. I work with a substance called pentaerythritol - I am certain that I do not want to nitrate that one as it is a precursor for a number of things that go bang. 13 hours ago, John Cuthber said: You just broke my irony meter.

I'm not saying all knowledge should be deleted from the internet - it wasn't me that said that - I agree with the sentiment that the knowledge is not necessary for the public domain and that I personally do not care for making bombs. 1 Link to comment Share on other sites More sharing options...
