I’ve heard that using a paint mixing booth or a paint spray booth is the easiest way to create an approved extraction room. Is that true?





Not necessarily. This option may be viable if all of the appropriate criteria are met. Possible issues could include: the ventilation exhaust ports are not located within 12” of the floor; electrical outlets may need to be added or modified, and/or structure does not provide a 1 hour fire barrier. Typically, the exhaust fans provided with a spray booth or mixing booth are capable of producing air flow between 4,000 and 13,000 cubic feet per minute. Per the IFC, the required flow rate in a large paint booth (350 square feet) would be no more than 350 cubic feet per minute. The energy cost required to run the supplied exhaust fans may be cost prohibitive in the long term.

This is just saying you need to think of the whole area and install things correctly.

The booth alone is not enough but it is a GREAT start. It gives a defensive place to contain a fire before it grows. Adding a fire suppression system is really easy to a booth. Everything has to be installed per NFPA and UL standards.

That info about blower sizing is WAY off.

You take the opening of the filter bank/opening/ door and multiply that by 100. (For the old and easy way to do it). The new way requires lots of testing equipment and crazy math. The old way works close enough to still use.

A small walk in booth with a 10' x 8' filter bank would require 8000 cfm blower.

Not only do you size the blower but you also test the air flow to make sure you have the min amount of air moving fast enough through the booth.

I think the last small booth I installed used a ½ HP motor on the blower. That is not a huge energy hog. The heat lose when the blower is running is also an issue. Will you need an air make up unit? Will the make air need to be heated? Energy costs are just part of it if you need proper ventilation. Running extractions does NEED ventilation so you will have to do one way or the other and any will take energy. A spray booth is just a cheap and easy way to start building an area.

Can you link this engineering site?

[Lefthand]

sure. Never worked with a paint booth myself just happened to stumble across their site
when I had questions about extractor certification. Especially after seeing that terrp had a Wyoming engineer stamp on their certifaction.

Anybody have a gas sniffer hung up where there working?
They sound great gives you a heads up. https://www.amazon.com/Halogen-Detect.../dp/B00EZN4QS0

To run safely and to pass Fire codes etc you are required to have an alarmed hydrocarbon detector. They are a great idea. Just make sure you get one that works for general area detection and not one that can only sense a tiny area for pinpoint leak detection.

thanks GW for the safety info

thinking about storage of my R600 tanks and am uneasy with the heat of the out buildings in consideration. Would a lined hole in the ground, similar to a wine celar idea, be dangerous?

[Gray Wolf]

Should work, with the ground staying a constant temperature, but a hole in the ground will collect any leaking gases, so I would also use an HC detector.

Great Thread appreciate all the support and information @gray wolf
