Could one re-purpose a respirator to prevent noxious fumes from escaping?

Hi there! I have had this idea in my head for some time, especially now that I am looking into metal etching. But I am an apartment dweller, with a cat. Now, I know that this is pretty broad. So I will give a specific example: if I build this Can I build also a tank using say, these acid-gas cartridges in-line with the exhaust of a vent system to clean out the chlorine? Would this work? Would it be safe? Would it allow the relatively slow out-gas of hydrogen to disperse, or would it concentrate it? Any thoughts at all? Thanks! Ernest.

toxic copper fumes

I have made a tabacco pipe out of a brass bowl and a copper pipe that fits into the bowl. i have heard that copper gives off toxic fumes. will it do so if it is burning in the brass?

Is soldering a health risk?

I was just wondering how (aside from being clumsy and burning yourself) soldering can be a health risk. I would suppose the fumes would be bad for you, and is there anything else? And is it safe to solder in an average room in a house, or should I do it outside for better ventilation?

How can I make a fume cupboard/ fume hood?

Hi all! I am trying to make my own fume cupboard/ fume hood to keep my acids in for my jewellery workshop, I am unsure what type of fan I need to suck the air out? The fume box will sit bellow a window so should I attatch a pipe from the back of the box to the window? If so, how does the air get sucked out? Regards Christy

Can I etch a PCB in the winter...? Answered

I want to etch a PCB, but it is rather cold where I live. I had settled on the HCl/Peroxide mix, but I could use something else if need be. I wouldn't be worried about it, except I get the impression it's a good idea to carry out the reaction outside, where it is cold right now. If working outside in the cold is a no-go, is there any etchant that is "safe" (I understand that safety is relative, I mean along the lines not immediately gassing me) to use indoors with ventilation? If so, how much ventilation is needed? Are we talking an open window, or an industrial fume extractor? Also, I wasn't sure which category and channel would be the best, so if a mod or somebody sees this and has a better classification, go ahead and change it. Sorry for making this such a long question; I'd just like to be able to use my circuit board before I die ;). Thanks, dedgerton

How build a cost-effective device that automatically clears exhaust fumes out my garage?

Soon I'm going to move into a building which shares living quarters with a garage. I'd like to rig up some sort of relay-triggering device that opens a nicely sealed set of vents (one intake, one output) and activates a fan exhausting garage air  - one that activates the minute I open the garage door, and then continues exhausting fumes for a few minutes after I drive the car away (and close the garage door). After those couple of minutes, the fan would stop, and the vents seal shut Due to the "lay of the land" (garage right off a busy road, with very short hidden driveway) I will be backing the car in, so exhaust gases will be concentrated at the back of the garage (close to living areas) - rather than near the open garage door. And as my car has a turbocharger, I often need to let it idle for a minute or two ( to let the turbo cool down) before turning it off to park. So it would be most useful to be expelling those exhaust fumes out of the garage! The question is - what's really the most simple and cost-effective platform for this kind of a system? Could a 555 timer, a few discrete components and some relays do the job elegantly? Or am I better off just diving into Arduino-Land?? Any related ideas (solenoid-closed vents, efficient fans, ducting through walls, etc ) that are especially thrifty - would also be greatly appreciated!!!

Is lighter flame/smoke/fume toxic?

I was going to make an instructable on mini roasting when something hit me. When you use the lighter to light maybe a marshmellow, is the fire or smoke or fumes from the fire toxic? I mean the gas/alcohol gets neutrilized when it burns up and turns into flame but If i cook with it, it may be a different question. If someone asks me to think about smokes, the I should say to you that smokes are already toxic and anyone smoking shouldn't care. ( I don't smoke, I want to live) If possible you can answer this question and have credit in my next instructable.

Safety of laser cut foamboard (fumes, etc)? Answered

So I cut some elmers 3/16" foam board today on our schools laser cutter- it gave off some nasty fumes but luckily most of it was ventilated out of the cutter. My concern is that inhaling the fumes (or the low-volume fumes i got from whatever smoke was left in the laser cutter), will be pretty bad for you. I dont know how toxic the fumes are from laser cutting foam, but my guess would be pretty bad. I also read somewhere that heating the foam up produces a lot of toxic byproducts, one of them being cyanide... Is this stuff safe to handle? I did feel a bit "foggy" afterwards, and had a slight pain in my chest, but not a lot...Thanks!

Solder fume extractor with carbon and HEPA filters?

I have been reading about the subject, and most articles tell that carbon filters are good for solder chemicals, fumes and odors, while HEPA filter are designed to remove dust, allergens and micro-organisms from the air. Supposedly, solder fume extractors should use both filters for an efficient filtering of the chemicals. Is this correct? Thanks for your time!

Construction ideas for this concept?

Recently, I have been working on a gas 'vaporizer' that evaporates gas before being fed into an engine. During my short-term experiment, I found that this saves ~70% (+-20% for crudity of measurement.) This works because the vapors will burn more thoroughly and cleanly, leading to higher apparent efficiency. Below is a basic diagram of how the system works. You can see there is a container that is half-full with gas, and a hose goes down with many small holes. As the engine's compression draws a vacuum on the container, air will come up through the holes. As it rises, the gas-air surface area rises dramatically, leading to the vaporization of gas. To further increase the surface area, I also added a felt liner on the inside to allow the gas liquid to rise and evaporate. The final mixture ends up very rich, so to compensate, a 'T' fitting has been added to allow air to mix in with the vapors/fumes. Some valves have also been added to control the air inlet (similar to a 'choke') and the amount fed to the engine (similar to a throttle. In fact, it is possible to use the original throttle or choke as a throttle on the carburetor on my tractor!) The problem is: My original design utilized a plastic folgers coffee can, and the flimsy plastic top was hot glued to a thicker plastic cutout for strength and support. Since most glues will dissolve in gasoline, including hot glue, it could not be used. most did not hold anyway. I also tried JP weld plastic cement and it did not hold at all. I had to trash this build. I did, however, get enough use to run the tractor for several minutes while testing gas use. I found that the tractor used nearly twice as much simply running on gas than the fumes. I did not have the float valve and electric pump hooked up with the prototype. Also the 3/4in housing I used may be a bit constrictive and also seems to get slightly damaged by the gas. It will not be a long-term solution.  So I need to redesign the project, and I am thinking of using a 1-3 gallon bucket that is sealed or a gas tank. I need good almost air-tight seals on everything. I am asking for any ideas related to the construction of this device and any tips you may have.

Fiberglassing inside a studio apartment?

First off, I want to preface I know the dangers of fiberglass fumes, and will not do anything too stupid: I'll only use it if it works and is safe. Anyways, I live in a studio apartment downtown, so outdoor space to do stuff like this is non-existent. On top of that, I don't have very many good friends in town, as most have moved away, so borrowing a hunk of lawn elsewhere is a bit of a pain. My question is: is there any sort of fume hood I could make/buy (that won't break bank) that would be big enough to work on a helmet in, and would be able to extract the working fumes, along with the drying fumes. Noise isn't a major issue, but the quieter, the better.  Alternatively, is anyone knows of any sort of trick place to work (like a back room in a hardware shop) I'm open to suggestions! Thanks in advance.

Does synthesizing Sodium Chlorate NaCl03 produce any harmful fumes if i electrolyize the solution while it is hot? I saw on wiki if you heat the solution while electroyzing the solution the reaction is NaCl + 3H2O = NaClO3 + 3H2 but if it isnt hot the reaction is 2NaCl + H2O = NaClO + NaCl + H2O , NaClO (Sodium hypochlorite) is what is used in household bleach.

How to prevent gasoline fumes from seeping into my house/garage from a neightbours garage?

Hi all, Back again with another issue regarding the money pit. I live in a townhouse and my neighbours have two motorcycles in their garage. They leak gas and I am guessing pretty badly because I cam smell it in my home. When their garage hasn't been opened in awhile it's fine, but when it opens, I am supposing the pressure builds up and BLAMO It comes through the vents in the house or around the vents in the house. My garage even smells strong of gasoline and I have nothing in it that uses gas. Is there anything I can do? Besides to obvious and talk to the neighbours, and the condo corp, two things I have already done. It wasn't bad in the summer because they were in and out and the windows were open so there was less pressure, however, when I arrived home last night it smelled like a flippin gas station in there! I am waiting to hear from the condo corp, trying to be proactive because clearly this issue isn't one they are tending to with immediacy
