So my layout is about 6ft from my Gas Furnace in the basement. Im worried about using Water and Isopropyl Alc to glue down all my scenery. Are there any other recommendations that are Non-toxic, Non Flammable you guys have? I just have this terrible fear of bringing the ship down

Welcome to the forum, Will_Schneider!
You can mix a few drops of dish detergent with water and spray it or drop it onto the scenery.

Sounds good iâll give that a try, any other issues with it being in the same room as my furnace other than just Fume releasing liquids/materials? Humidity and tempature is never an issue in the room.

I think you will be OK. However, Iâm not the expert on this, so maybe someone with more experience will post.

You could just hit the switch on your furnace and turn it off if you are worried. The alcohol evaporates quickly at which point you can open a door or window, wave a towel around for five seconds and turn your furnace back on. I would only be worried if you dumped the bottle over and for that reason alone it would be worth turning the furnace off and donât forget the hot water tank if it is also gas.

Sounds like a plan thank you guys, I do know my water is electric.
Anything under 100 proof equivalent is non-flammable, âby definitionâ. You are using the alcohol as a reducer of surface tension in the ânooks and cranniesâ before you apply the water-diluted glue and detergent solution. So as long as you dilute your alcohol below 50% (bottle strength of normal ârubbingâ alcohol is about 73%) there will be no concerns with vapor flashing.
In any case, remember that when the furnace is actually firing, there is negative-pressure draft to the burners and igniter, so any alcohol vapor would be extracted and probably pyrolyzed. And it would take a hell of a cloud of alcohol vapor to produce a âpuffâ from contact with a pilot-light flame.

So I just took a closer look, Misindetified my furnace⌠I wanna say itâs a heat pump. Thereâs nothing on it saying âFire Hazardâ I looked up the model number as well. Everything on it either says Carbon Mon Hazard or Shock Hazard⌠there for can i use all the Isepropyl I want??? 
My layout is in the basement. I open a window at both ends of the basement, and run a fan to draw air out.

If it is noted as a Carbon Monoxide hazard, combustion (and potential flame source) is indicated. A typical âheat pumpâ system would use electric resistance elements for âemergency heatâ; a typical dual-fuel system (in the olden days) used gas for heat and typical air-conditioning for cooling. I wanted to buy a heat-pump system that used gas combustion (e.g. with a catalytic burner) as a âheatâ source for augmenting heat-pump efficiency in winter, but to my knowledge there is no such system; youâd have to cobble it together yourself with parts from a GSHP system.
That said, youâll be in far more trouble from isopropyl alcohol as an inhalation hazard than you would as an ignition hazard.
Is that because you donât have a dog to blame it on?

If in doubt⌠donât have any âheat sourceâ upstream of the solvent or whatever.
Yeah, the furnace and water heater are not in the cross wind.

okay so since there electric im good?
Yeah, but use some source of ventilation anyhow.
Yes i gotcha thanks
As a former teacher of such. I love the detail provided âWokeâ. I have about a dozen questions reference your last emailâŚto be sent via email later. Thanks for your posts. regards mike endmrw0930251010
