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.
