I do not believe there is a standard, but for perchloric acid fume hoods it is recommended to use fume hood monitors that are built for special purposes, such as biological safety. These monitors are water resistant, and since biological safety cabinets and perchloric acid hoods are intensively washed and decontaminated regularly, it is (at least economically) prudent to get a compatible monitor.

Does anyone have information on air flow monitors that may be approved for (or not approved) use in perchloric acid hoods?

We also use the ANSI/AIHA Z9.5-2003 Laboratory Ventilation standard & NFPA 45 for fume hood requirements.

There is no specific OSHA requirement for fume hood monitors.  The applicable reference is the OSHA Laboratory Standard, which requires the chemical hygiene plan to include:
1910.1450(e)(3)(iii)< /i>
A requirement that fume hoods and other protective equipment are functioning properly and specific measures that shall be taken to ensure proper and adequate performance of such equipment.
While newer laboratory hoods generally include a built-in flow monitoring device, older hoods are commonly tested periodically using a portable flow monitoring device such as a vaneometer.   Testing frequency should be addressed in your chemical hygiene plan; many facilities perform such testing quarterly or at least semi-annually.  Additional local codes or insurance requirements may make more frequent testing necessary.

Could you site the requirement for fume hood monitors.  We are located in New York State (upstate) and are not aware of such a requirement.
