You can apply at the NFPA site (www.nfpa.org). Recognize that the committee's main emphasis is on fire safety not on ductless hood operation and maintenance. You may want to get a copy of NFPA 45 first and read it as I suspect it is a lot broader than you may recognize. There will be a period for public comment once the committee reaches the first draft stage and anyone can input a suggestion or revision.
(In the interests of full disclosure I am on the NFPA 45 committee.)

That is a committee I'd like to volunteer for or find a way to keep up on their process. The art and craft world is just full of these damn things including ductless spray booths.
I've been a voter on NFPA 1126 and 160 for many years. I don't remember how to get on a committee. Any advice?

Excellent advice.
The NFPA 45 committee is so concerned about ductless hood claims and performance that they have formed a task group to look into new code requirements for the next code cycle (in 2022).

Subject: [DCHAS-L] Ductless perchloric acid fume hoods???
Hi Everyone!
I have been having a dialog on my Linkedin Web Page with many people lately regarding several aspects of perchloric acid fume hoods. Suddenly, two separate researchers in Africa started extolling the virtues of ductless perchloric hoods. One researcher claimed the hood he used "neutralized" all acids, including perchloric acid, the other (at a different facility), claimed the carbon filter "filtered" poisonous fumes
At first, I sincerely thought this was some sort of random misinformation.
Then I googled the term and came up with this advertizement:
"Cheap Steel Chemistry Lab Table Top Ductless Perchloric Acid Fume hood with accessories $900.00 each with accessories"
Photos, color choices, and delivery details were provided on the ad which cannot be attached to this email sent to this forum.
Wow!
There are plenty of reasons to be scared to death about the ability to have such an item pop up for sale anywhere in the universe. I just pray that purchasing agents do not get in a rush to order a product they have only marginal knowledge about. In our business, this unfortunately happens frequently. Especially when the price is low.
Clearly, explosive peroxide formation with carbon filter material and residue issues are well known with perchloric acid reactions. I am also sure stuff like this happens all the time on many fronts with lab safety items.
Please, PLEASE, contact any reputable manufacturer regarding perchloric acid fume hoods and get more details regarding what one needs to exhaust such procedures safely.
