8. The building ventilation system must be so constructed that air from the containment to other areas within the building Air may bp ed laboratory- Biosafety level 3 is not recirculate high-efficiency particulate air (HEPA)filtered, reconditioned and recirculated within that la boratory
8. The building ventilation system must be so constructed that air from the containment laboratory – Biosafety Level 3 is not recirculated to other areas within the building. Air may be high-efficiency particulate air (HEPA) filtered, reconditioned and recirculated within that laboratory
When exhaust air from the laboratory(other than from biological safety cabinets) is discharged to the outside of the building, it must be dispersed away from occupied buildings and air intakes. Depending on the agents in use, this air may be discharged through hepa filters. a heating, ventilation and air-conditioning(HVAC) control system may be installed to prevent sustained positive pressurization of the laboratory. Consideration should be given to the installation of audible or clearly visible alarms to notify personnel of hvac system failure

9. All HEPA filters must be installed in a manner that permits gaseous decontamination and testing 10. Biological safety cabinets should be sited away from walking areas and out of cross- currents from doors and ventilation systems (HEPA =high-efficiency particulate air
9. All HEPA filters must be installed in a manner that permits gaseous decontamination and testing. 10. Biological safety cabinets should be sited away from walking areas and out of crosscurrents from doors and ventilation systems. (HEPA =high-efficiency particulate air )
11. The exhaust air from class i or class li biological safety cabinets(see Chapter10), which will have been passed through hepa filters, must be discharged in such away as to avoid interference with the air balance of the cabinet or the building exhaust system
11. The exhaust air from Class I or Class II biological safety cabinets (see Chapter10), which will have been passed through HEPA filters, must be discharged in such away as to avoid interference with the air balance of the cabinet or the building exhaust system
12.An autoclave for the decontamination of contaminated waste material should be available in the containment la boratory. If infectious waste has to be removed from the containment laboratory for decontamination and disposal, it must be transported in sealed, unbreakable and leakproof containers according to national or international regulations, as appropriate
