In order to meet EQc5 requirements, do science prep rooms have to be independently exhausted even if fume hoods are installed (given deck to deck partitions and self-closing doors are present as well)? Thank you!

To determine the answer to this question ask: Are all the potential indoor pollutants housed in the fume hoods? If you have a separate chemical storage area, or if chemicals are ever in the room outside the hood, they would also need negative pressure and exhaust. Are the fume hoods on whenever a potential pollutant is inside the hood (sealed or unsealed) during occupied hours? If you can justify that occupants are protected by your design from potential exposure, clearly document your strategy and rationale.
