Laboratory Fume Hoods

Laboratory Fume Hoods

Laboratory fume hoods and bench scale laboratory equipment used for chemical and physical analysis, usually vent separately from the building’s heating, ventilation, and air conditioning system and not recirculated into the building. Accordingly, volatile toxic air contaminants (TACs) generated by a laboratory activity will emit to the atmosphere directly from the laboratory fume hoods.

For minimizing the emission of toxic air contaminants, facilities should follow “Responsible Laboratory Management Practice” that includes all of the following measurements:

  1. Open container procedures involving materials that contain volatile TACs shall be avoided where feasible.
  2. Open container storage of volatile hazardous chemical wastes shall be avoided.
  3. Training for laboratory employees handling hazardous materials shall include information about minimizing the emissions of volatile TACs. Their employees shall be directed to avoid open container procedures involving volatile TACs where feasible, and to avoid open container storage of hazardous chemical waste.
  4. Fume hoods shall be posted with notices reminding employees to avoid open container procedure using volatile TACs where feasible. Laboratories shall be inspected periodically, but not less than annually, to confirm that these notices are present.
  5. Laboratory fume hoods shall be monitored periodically to assure proper face velocity.
  6. Evaporation of any hazardous chemical waste containing TACs as a means of disposal shall be expressly forbidden.

Who Needs a Permit?

A Permit to Operate is required for each of the following equipment and operation:

Permit Fees 

New Installations:

Dust collection systems are required to submit a one-time NEW APPLICATION fee for applying Authority to Construct/Permit to Operate (Rule 300 District Fees).

Modifications:

For modifications resulting in any physical change or change in method of operation shall pay the MODIFICATION fee specified in Rule 300.

Permit Application Completeness Determination
