<whitequark> "During this process, white fumes are emitted. These are likely sulfur trioxide. Avoid coming into contact with them."
<whitequark> "avoid coming into contact" with "sulfur trioxide" is an understatement of century
<whitequark> christ
<rqou> i mean, that's why there's a box fan

<rqou> whitequark: ok, i "improved" that part of the procedure

<azonenberg> "Depending on your living situation, this will also escalate the problems with that one other housemate that you are not on speaking terms with."
<azonenberg> lolol
<azonenberg> is this from experience? :p
<azonenberg> "If you somehow determine that this is not the case, abort the experiment and run away as fast as you can."

<rqou> so the first part is
<rqou> the second part was added after whitequark called it an understatement
<rqou> so basically i did _not_ experience an exposure to SO3
ZipCPU|Laptop has quit [Ping timeout: 258 seconds]
<rqou> so azonenberg: any major errors/issues?
<azonenberg> nothing obvious
<rqou> good coverage of failure scenarios? :P
<azonenberg> i think?
<rqou> in other news, running a release build of xc2bit OOMed my machine
<azonenberg> Somebody needs more RAM
* azonenberg included
<azonenberg> 32GB isnt enough for me...
<rqou> btw, how many lab incidents have you had over the years?
<azonenberg> Define incident
<rqou> i know you overheated some candles :P
<azonenberg> Off the top of my head... I cut my finger on a glass plate i was polishing something against (the edge was sharp)
<rqou> hmm
<azonenberg> I had that one that i mentioned where the sulfuric drop boiled and the beaker tipped over
<azonenberg> As far as the candles go, i wouldn't consider that an accident
<azonenberg> It was an unexpected outcome, but there was no real risk of injury
<azonenberg> it was well controlled outdoors on a non-flammable surface
<azonenberg> And, while not *expected*, it was a plausibly anticipated outcome of the experiment
<rqou> heh, the "outdoors" here is probably just as flammable :P
<rqou> it's full of plant debris that nobody gives a shit about
<rqou> the landlords do technically pay a gardener to leafblower stuff around once a month or so
<azonenberg> Yeah this was on a concrete driveway
<azonenberg> I had a fire extinguisher on standby, but could have probably just waited for fuel exhaustion
<azonenberg> the only thing i consider "wrong" about the experiment is that i didnt consider the wind velocity and it did blow flames closer to the wall of the garage than i was really comfortable with
<azonenberg> Which is why i blasted it with the CO2
<azonenberg> But there was no property damage and no injuries
<rqou> but you don't have any "However, if you have an antagonistic relationship with your landlords like me, you might skip this step and just pour the waste solution down the drain with the tap turned on to further dilute."
<rqou> or similar :P
<azonenberg> No, lol
<rqou> oh btw, my hotplate still works after this
<rqou> :P
<rqou> the only permanent damage is a burn mark on the carpet
<azonenberg> In general i have a very clean safety record because I tend to make heavy use of engineering controls and use small amounts of things
<azonenberg> The candle incident actually is a great example of processes not scaling linearly
<rqou> which we don't care about because it's the cheapest possible carpet that was only installed when the original group of housemates moved in
<azonenberg> one of those candles by itself didn't hit the flashpoint
<azonenberg> five together did
<rqou> we're already not getting any deposits back anyways because other housemate ripped a giant hole in the drywall
<rqou> er, not the drywall
<rqou> the decorative whatever-it-is
<rqou> by trying to gorilla-tape an htc vive lighthouse to the wall
<azonenberg> But, while i hadn't anticipated that *exact* failure mode
<rqou> turns out those are heavy, gorilla tape is good, and the wall isn't :P
<azonenberg> I was fully aware that I was playing with nontrivial (though small) amounts of flammable materials, and the potential for them to burn faster than intended was very much present
<azonenberg> Not only playing with flammable materials, but intentionally igniting them
<azonenberg> I didn't go so far as to wear full Nomex, but that's because the amount of stuff involved was so tiny
<azonenberg> And i did have a face shield in case anything flew that way
<rqou> yeah, this experiment was a bit yolo without proper risk assessments
<rqou> but now there's a procedure! :P
<azonenberg> I always try to do some level of risk assessment
<azonenberg> like, when i was mixing up my alcohol based fuel i considered the potential of a spark from my blender igniting the fuel gel
<azonenberg> I had the CO2 on standby, plus (as a less extreme alternative) a thing of aluminum foil or watch glass i could smother it with
