Phosphor-ing

I made the mistake of not having my goggles on when working with muratic acid one time, and one time only! I had a good sized drop splash up, and as luck would have directly into my right eye. I was taking an emergency shower labcoat and all for about 20 minutes while I tried to keep my burning eye open! Lesson learned: NEVER ENTER A LAB WITHOUT PROPER EYE PROTECTION! Fortunately, I didn't learn this lesson at the expense of my eye.

I'm going to be using a bilge fan for my hood. They are rated at 350-450 cfm with either a 3" or 4" inlet. They are made for flammable vapors so they are sparkless motors. The best part is they are CHEAP:-) costing about $25-30 +shipping. This should more than handle the face velocity I'm looking for. Like I said before I'm still a couple of months away from this project so it is still in the design phase, but I plan to take pictures of the construction of this hood for all to see. Picture should tell a more complete story than my descriptions can. I'll even try to take a picture of a smoke bomb inside to prove it works.

HEET gasoline additive is methanol. It's used to safely remove water from gas tanks after a car has been sitting for too long. Google "goldeagle" to find a store that carries this near you. I can't attest to it being absolutely pure but it is real close.

My fume hood will have it's own piping to the outside air. I also plan to incorporate at least two activated charcoal/carbon scrubbers. My questions were about wind currents in the area of the hood. And about the amount of filtration necessary to "clean" the air pumping outside. Ecoli you must live near me:D . The engineers, I use that term loosely, in my town built a little island at a large intersection. It has a flagpole and is called something to the effect of "freedom island". Anyway the crosswalk to get to said island is in the middle of a blind curve:eek: that leads directly to a hospital! They could have placed it 50-100 feet sooner in the curve and then both driver and the pedestrian could see each other! I mean who puts a tourist (lol) attraction in the middle of an intersection anyways!

Also if anyone is considering building their own fume hood needs to read this. http://www.saai-svc.com/technotesarticles/evolution.htm

I will be purchasing a house in the not too distant future. I haven't found the right one yet, but it's only a matter of time. My question is what kind of considerations should I give to location of a homemade fume hood within the home? Also should I be aware of any drawbacks to using epoxy based paints or should I use Teflon based paints to coat the inner surface of the hood? I am planning to build this fume hood to be at least 4' across and 3' deep so space won't be a problem inside the hood. I have planned to make a perforated plate baffle (back and top) to even out air flow through the hood. And even considered a spray down system for the exhaust if I ever want to experiment with something requiring use of perchloric acid , I really doubt that will ever happen. My initial designs included an inline hepa filter and activated carcoal scrubbers before venting outside. Would this filter/scrubbers combination be adequate for a fume hood? Or how can I improve on this idea? I won't be moving for a month or two so there is no rush to build. Just trying to get an idea of what I should avoid when selecting a home. Thanks for any help I receive. If this is in the wrong forum please move it accordingly. I posted here in chemistry because I will be using this for chemistry, organics mostly.

Hey, I'm Phosphor-ing I love science and anything to do with chemistry. I also enjoy music. I play the drums and acoustic guitar. I hope to be going to college to be a chemical engineer soon, but I have to save a little longer to afford it. Anyway, I'll be posting from time to time and I hope to meet each and everyone of you.
