Fume hood ideas.
Hi, guys!  What´s up?
I just wanted to ask you guys if anybody have made their own fume hoods at home, and if they have any tips for me.
I am thinking about making one at home, like this one here.

I have the wood material, and the fan, so im confident that i can throw one together soon.
One thing i want to do is fire proof it and all that. So i am thinking about painting the inside with steel epoxy or something similar.
It doesn´t have to be fancy, i just want it to work properly.
I would be very greatful if you would take your time to help me out.
Have a greaat day guys!
/Nannah.
Ps. If i want to proof the fan of explosions, how´s it done?

I know nobody likes hearing this, especially when they're new but UTFSE. There are so many threads about this. Here's a links: https://www.sciencemadness.org/whisper/viewthread.php?tid=11...

Explosion proofing I'm not so sure. Use a brushless fan definitely.
Good eyes

I know, i shouldn´t have posted this thread from the beginning, but i couldn´t help myself. I want everything going my way during the constuction.
I am a little bit unsure about some things, like what i am going to use to coat the inside in order to fire and corrosion proof it.
I read somewhere in a fume hood booklet, that the hood should really be made of stainless steel, but i am a little bit broke right now, so i am using
plywood, or something similar.
I read somewhere that you can use the kitchen exhaust fan. As i understand it, they made temporary walls out of plastic or wood and boxed it in.
Someone?
I mean, as long as the pulls a good amount of fumes out there´s no immeadiate danger, right?
About my fan. I have one that´s exactly like the one in the picture in the link below. I think it can work becouse the wires is on the top box.

I want to say sorry, and thanks to everyone, and especially you, thesmug.

You just need to make a WorkSpace that is easy to partially seal, and has a fan in it leading the fumes to somewhere else.
Do not Seal the front door, or the fan won't be able to suck air in to replace the fumes.
Explosion-proof is not a reality. If you set off an explosion in your fume hood, time to build a new one.
Personally i made mine with a glass trough as the bottom part (made from sheets of glass and silicone sealant) so if anythg breaks, the mess will be
contained.

I won´t use it for setting off explosives, what i meaning to ask what the best solution for me to avoid sparks that may ignite any nasty fumes.
I am just starting out experimenting a little, so i don´t see myself doing any super dangerous experiments soon. I am hoping to try making
Chloroform, but i don´t want to try it without all safety stuff out of the way first.

It may be better to start with simpler and safer reactions.
There is no substitute for experience.
e.g. i once added conc HCl to hot potassium hydroxide solution.
In igorance, i was not prepared for the violence of the reaction, so by sheer reflex, i threw HCl all over the place.
Next time i will know what to expect, and will spray less HCl everywhere.
