As always there are states that have more stringent guidelines associated with permitting and reporting requirements associated with fume hoods. In generally, its also not a bad idea to check with your department if you have questions about the fume hoods since there are some states and local regulatory agencies that may have more strict requirements than the Federal requirements.
In addition, some schools have prepared an estimated emissions inventory to assess what air quality regulations may apply.
The purpose of a chemical fume hood is to contain and exhaust chemical and/or radioactive material so the user and other lab occupants are not exposed. Chemical fume hoods are certified annually according to the SEFA-1 Standard. Copies of certification reports are available.
Chemical fume hoods located in the Hutchinson Center buildings are equipped with digital face velocity meters. The meter should read 100 ± 10 linear feet per minute of airflow into the hood. As the sash is moved up or down on these hoods, the airflow increases or decreases to maintain a constant face velocity.
Chemical fume hoods in Center lab buildings are equipped with baffles that users may adjust easily. Under most conditions, contaminates generated within a chemical fume hood mix quickly within the hood and the mixture will have a density nearly the same as air.
The farther behind the protective air barrier you place the source of contaminants, the greater protection the hood provides you. Therefore, you should place contaminates as far back in the hood as you can without blocking the bottom baffles or creating an ergonomic hazard when reaching.
