what about the fumes off the plastic cooking? will it harm you i do my cooking in the garage with the big door open thanks ahead for input . minnow asipo123

Direct exposure will cause shortness of breath. Burning or boiling the plastisol will release hydrochloric acid fumes. Plastisol gives off oily vapors when it smokes.

Use an organic vapor respirator and/or build an enclosed booth w/ adequate exhaust

Wear the respirator or build a booth w/ adequate exhaust. and avoid permanent damage to you respiratory system

Example of a small,adequate booth w/ an open front-

25"H 25" W 36" depth w/ a 360 cfm fan located in the center ceiling of the booth

BTW- plenty are still using/heating pyrex cups which are hand grenades w/ glass schrapnel when they explode. I speak from experience.

This is something I have been wondering about as well. Can anyone take a picture of the ventilation set up or a booth like you described Smallmouthaholic? Everything thing says to work in a well ventilated area, but I really don't know the first thing about proper ventilation. If you just do it outside is that good enough?

Every video I watch no one and I mean no one is wearing a mask or anything and half the people look to be doing this in their basement. Is this a real hazard to your health or is this just about being extra cautious. I have poured lead in the house for years and that is a hazard as well. Is this comparable to that or a lot bigger deal.

Any input on a decent yet affordable organic vapor respirator and/or info about best places to look for them is appreciated.

Thanks

I pour my soft plastics in the garage near the open door, I place 2 standup fans between the table I am working on and the open garge door, with the fans blowing outwards into the open. This works very well to extract any nasty fumes, it also stops strong air currents being blown onto your molten plastic which could cause pouring/melting issues whilst you are working.

Just because no one is wearing one doesn't mean it's safe. There are plenty of fumes associated w/ hand pour/injection operations and Presto pots.

Any HVAC technician,tin knocker or a fabricating shop can make/or have one made out of galvanized sheet metal duct work. They had to be supported in the front corners to reduce sway and mounting a shelf in the back helps too. The minumum fan required is a 360 CFM w/ 10" duct work. Then you'll need seperate wiring from you fuse panel to run a microwave,Presto pots and lead melting equipment together. A certified electrian can provide this service. Fan blades should be cleaned and waxed for maximum performane monthly-especially if you air brush paint in the booth.

Melting lead around fumes in absolutely dangerous. Have you lead blood levels checked.

I'm simply amaized @ the number of folks who try to avoid an adequte exhaust booth. Yes they cost money to set-up properly-up to 1k if you do it properly(on a small scale) w/ a stand,booth, exhaust,lighting and switches. I realize this is a hobby w/ many but it's cheaper to buy your baits then spead all the $ to do it properly w/ CNC molds.

BTW- I live in an area that can see winter temps go to 5 degrees farenheit for low temps w/ high temps in the teens and 20's. Open the garage door?? you've got to be kidding.With all due respect,I do work 12 months of the year making baits/jigs and heated/ air-conditioned/insulated the shop so when outside temps go extremes I'll be comfortable.

Your safety and respiratory health should come 1st

These work well but have to be replaced w/ you start smelling fumes and/or solvents. Also-if you have a cold when using a respirator, wipe out the mask before each subsequent use w/ Listerine and a cotton ball so the germs don't re-infect again. The price for this mask is absolute peanuts to protect your respiratory system. Pardon me but if you can't afford a new respirator or an adequate exhaust booth stay away from making your own plastic baits. Continuous breathing of plastisol fumes will eventually damage your respiratory system

actually that is after 8 hrs of use

I sprayed pesticides for 20 years-tree and turf-Respectfully they'll last longer then 8 hrs. I used them when I had a smaller booth, poor, inadequate exhaust fans and they lasted 2 weeks- not sure why you had only 8 yrs of use unless you were painting cars. Now if you're using them over a smoking plastisol pot ,then I can see them having a very short life. Even w/ a mask,plastisol will burn and even hamper your eyesight w/ out use of an adequate exhaust booth-been there done that years ago.

[SHK]

as per manufacturers specs, they are only good for 8 hrs exposure to air before they are no good. been using them for nearly 20 years as well.

Here's the ones I use. I guess my use is more intermitant then I realized. I only use them now when i paint w/ the new booth and exhaust system

i bought a 300 CFM kitchen hood at the big box store (a plus is that it has really nice lights!) and put it onto a plywood box I build to width. I used plexiglass from the front of the hood to the edge of my box...and then plexiglass part way down...to use as an eye shield and restrict flow.

So...I roughly have a 3'x3'x4' box...(36 cubic feet of air)..under a 300 Cubic Foot per minute fan. I vent the unit outdoors via a 4" duct (clothes dryer duct) making sure I had NO leaks in my system by gluing and screwing the hood vent coupling to the top. But some marabou feathers on top of your unit to see if you have any leaks!!!

Below is a pic before I added the plexiglass. I have since rotated my microwave side wards so that it blows the air out the front...under the hood instead of at me!




FYI...even so...I still wear a respirator!!!!

Store your respirator in a sealed plastic bag, or it will continue to soak up anything fumes that are in the air where it's stored, and will stop working sooner.

Good point I overlooked and have done for 20 + years
