Requirements:

Containment Level 3 (CL3) (Continued)
16. Exhaust air system to be independent of other laboratory areas. CL3
exhaust can be combined with areas of lower containment when provided
with a HEPA filter upstream from the connection. (For CL3 laboratories
manipulating organisms, such as HIV, that are not infectious via inhalation
this criterion is only recommended.)
17. It is recommended that supply and exhaust systems be located outside of
containment to be accessible for repairs, maintenance, cleaning and
inspection.
19. Where backdraft protection is required in accordance with local risk
assessment, supply air ductwork that is outside the containment perimeter
(e.g., between containment perimeter and HEPA filter or bubble tight
backdraft damper) to be sealed airtight in accordance with: Seal Class A,
HVAC Air Duct Leakage Test Manual, 1985. Sheet Metal and Air
Conditioning Contractors National Association Inc., (SMACNA), Chantilly,
Virginia.
20. Exhaust air ductwork that is outside the containment perimeter (e.g.,
between containment perimeter and HEPA filter or bubble tight backdraft
damper) to be sealed airtight in accordance with: Seal Class A, HVAC Air
Duct Leakage Test Manual, 1985. Sheet Metal and Air Conditioning
Contractors National Association Inc., (SMACNA), Chantilly, Virginia. (CL3
laboratories manipulating organisms, such as HIV, that are not infectious
via inhalation are not required to fulfill this criterion.)
21. Airflow control devices and duct sensors located downstream of the exhaust
HEPA filter and upstream of the supply bubble tight backdraft damper or
HEPA filter, or if located upstream, duct penetrations to be sealed in
accordance with: Seal Class A, HVAC Air Duct Leakage Test Manual, 1985.
Sheet Metal and Air Conditioning Contractors National Association Inc.,
(SMACNA), Chantilly, Virginia. (CL3 laboratories manipulating organisms,
such as HIV, that are not infectious via inhalation are not required to fulfill
this criterion.)
22. Bubble tight backdraft dampers and HEPA filters to be located in close
proximity to the containment perimeter. (CL3 laboratories manipulating
organisms, such as HIV, that are not infectious via inhalation are not
required to fulfill this criterion.)
(Continued on Next Page)
Although the phraseology regarding the
location of duct penetrations that need to be
sealed is rather ambiguous, it would be good
practice to seal all control device duct
penetrations as well as duct penetrations
made for any other purpose.
