I have school with a wood shop. There is a dust collector that exhausts saw dust from the equipment and recirculates the air back to the space after being filtered. The credit says "sufficiently exhaust hazardous gases or chemicals....in shops of any kind... with no air recirulation."

Saw dust is not hazardous gases or chemicals, and I have dedicated exhaust in the storage rooms where those types would be kept.

Would I still be able to pursue IEQc5?
