After a British teenager was killed by an explosion involving hairspray, a 3D printer, and flash paper, some worried that there might be consequences for at home 3D printing. It seems, however, that the accident was the result of the unlikeliest set of events and it is being viewed as such by members of the 3D printing community.

I know they say not berate the victim here but the flash paper, hair spray possible printer mods.... You can't blame the printing industry. The safety issues are minimal even with so called unsafe gasses emmitted when printing.
Shame on you. This is a terrible accident. Heartfelt condolences to the family.Quote:

please stop dragging this totally misinformed news item about 3D printer safety, while it's about common sense, and his parent didn't have it :(
True, but as with most accidents:Quote:

the accident was the result of the unlikeliest set of events
As an example, when I was a teenager I once set almost the entire top floor on fire because
1. I was using spray deodorant the normal way
2. A friend came in and fired a toy cap gun
3. The aerosol deodorant ignited and set a large bottle of nail polish remover on fire that had spilled a bit resulting in sort of a fireball. I expected an explosion so I kicked the bottle away.
Then further away into another room, leaving the carpet on fire. When I realized it was a plastic bottle that was still intact with only the outside spills on fire, and not going to explode I extinguished the fire with wet towels. Now I use neither aerosols, cap guns (or nail polish removers)
So, it is up to us to prevent these things from happening and let's first be aware that a common can of hairspray contains an amount of propane gas.
That is a very flammable propellant and because of the flash evaporation and high density of propane it sinks to the bottom of the room where it can ignite if there is a heat source or say a spark from an electric outlet.
Then, we have to be aware that an explosion from a can of hairspray is significant:

For me this marks the point where we stop using hairspray as anything else than hairspray and stick to other fixatives.
This is a terrible story and my condoleances to the family.
That's just nonsensical, the amount of spray needed is far below what your average woman uses to spray her hair,Quote:

we should just stop this discussion, it's going nowhere, and has nothing to with 3D printing, nd is only a very unfortunate collection of very rare circumstance,
and you would sooner die of emancipated power-hungry ants that want to dominate the earth and all the planets in the surrounding milky way, then from a 3D printer mishap !
Further to that if the risk is there and it is going to blow then I would much rather be spraying it at my 3d printer than at my head. :)Quote:

Yep this was a tragic accident, but nothing to do with 3d printers.
I think what needs to happen is that individuals assess how and where they use their printer and to ensure that if they use flammable propellents the area is well ventilated - and clear of other flammable material.
Without doubt this was an extreme case, but it brings home that even quite benign hobbies can create dangerous situations. Was the printer itself to blame? No, of course not, but a contributory factor was using a flammable substance as part of the process.
Take a look around your work area and see if you can identify any uncontrolled hazards. Think about sources of heat, stability of the printer, electrical safety etc. How many of us run our printers unattended? Do we need to take any further precautions because of this?
Its still a tragedy, so let's try and learn from the situation and prevent anything similar from happening again.
There's no evidence that the unfortunate victim of this accident was "stupid". And it's insensitive at best for you to call him that in a public forum. It's more about civility (or lack thereof) than morals. Shame would be an appropriate response to a breach of civility like this, but we all realize that shamelessness is more common these days, especially among anonymous participants in online discussions.
I think there are several things we can learn from this tragedy. One would be not to use hairspray with a flammable propellant, especially anywhere near a source of sparks. Turning off the printer and any adjacent electrical devices while preparing the bed would be a good idea. And not keeping extremely flammable items near ones printer would also be worth considering.
I am not using hairspray any longer - printafix works better anyway and the bottles are more manageable.
Another safety concern is the use of MEK (methyl ethyl ketone) as a solvent for PLA. People have been using this to smoothen parts and clean out nozzles. Under prolonged exposure this is veritably harmful to the nervous system and it is recommended only to use it with a full body overall + gas mask independent of environment air. It is better to just replace the nozzles, the prices have dropped anyway.
Perhaps having consideration for the feelings of others has gone out of style, but some of us try to behave well anyway. If anonymously casting blame on accident victims is your idea of a good time, I can't stop you from getting whatever enjoyment you get from that. I can only deplore it, along with other incidents of bad behavior that seem to be on the increase lately.
Damn dude... i am an ultra conservative gun carrying biker.... a true deplorable and you are a little insensitive to the situation.... and a lot disrespectful to the members here.Quote:
