I am currently finding myself in trying to deal with a fume hood problem. We had a mechanical problem that needed to be repaired causing The system to be shut down. Now that the system can be turned back on we need to have an air balancer come in and rebalance the system. After that my certification company would come in to certify that the hoods are maintaining proper CFMs for employees to work in them within the laboratories. The air balancer is in disagreement with the certification vendor. The air balancer says we have to have a policy that our face velocities for each hood must be 100cfm, where the certifiers are indicating that it's between 80 and 120 which that was what my understanding was.

I know this falls under ASHRAE standards, ANSI standards and OSHA standards, can you point me in the right direction of where to get the exact information?

Thank you, any information would greatly be appreciated.
