As consultants we need to bring these potential issues up to our clients when discussing how they will be using the BSC. • The flame creates turbulence in the laminar flow of air minimizing product protection. • Heat could melt HEPA filter bonding agents which destroys the filters effectiveness and loss of containment. • If flame goes out gas will be distributed into the space possibly reaching explosive limits. ( use of an class II -A2 70% recirculation) The BMBL states open flames are not required in the near microbe- free environment of a BSC and that touch plate micro burners could be used minimizing turbulence and heat buildup.…
