I am in the process of designing and building a swing-away vent hood for my
top loading square electric kiln and was wondering if there were any chems.
that produce flammable fumes or gasses that would present an explosion
hazard in the blower area of the vent system.
Does anyone have any advise?
thanks,

Free advice worth every penny, Wesley!
Obviously this would depend on what you fire in your kiln, but I've
never heard of any problems from oxidation firing by-products causing
explosions from sparks.
Is there a reason why you would want to use a vent hood as opposed to
the "negative pressure" kind of vent that Bailey, L&L, Orton,
Paragon, Skutt, and more use?
In my (free advice, remember) opinion, they much more effectively
prevent nasties from entering your environment and body than a hood
will, and they'll be much cheaper to build/buy and operate, and
quieter in use.
At some point I'll get around to posting my Poor Potter's
Prize-winning Project Pictorial (sm) of a home-made kiln vent. I
believe my total cost was under $65.

Fourth time was the charm!

hill 'round back. Too bad they sound like humans walking in my woods

Dear Wesley Derrick,
If you use a lot of wax resist then in the early stages of firing
there will be emissions which might present the potential hazard you
anticipate.
