Currently as my supervisor Geoffrey Bell seeks to complete the fume hood, all aspects of the new fume hood technology must be researched to test compliance with relative laboratory safety and testing codes and standards.  I will identify and analyze barriers to applying the low-flow fume hood technique with respect to relevant building codes and regulations.  Specifically, the most significant barrier is the stringent face velocity requirements of several of the codes and standards.  A few of the more influential codes and standards are outlined below.

• OSHA 29 CFR
• Hood face velocity - 60-100 fpm
• Monitoring device to confirm adequate preformance
• 4-12 room air changes/hour

• SAMA-SEFA 1-1996
• Class A Fume Hood - materials of extreme toxicity ~ 125-150 fpm
• Class B Fume Hood - standard lab chemicals ~ 100 fpm
• Class C Fume Hood - materials of low toxicity ~ 75-80 fpm

• NFPA 45
• Hood velocities to prevent escape of contaminants
• Hood air maintained at negative pressure to the lab air
• Energy conservation devices to be designed in accordance with ANSI Z9.5
• ANSI Z9.5
•  Hood velocities of 80-120 are adequate
• Hoods to be equipped with real-time monitoring device
• ASHRAE 110 is the recommended test
