To control the contaminant propagation, as well as the operation of the equipment such as the Bio safety cabinets, fume hoods etc.

1. Bio-Safety Lab Contaminant Control
A careful approach is required to design the ventilation of laboratories and Bio-safety labs to
maintain safety and protection to life and property. Major challenge is to control the contaminant
propagation, as well as the operation of the equipment such as the Bio safety cabinets, fume hoods
etc.
At DEINDE we ensure the desired performance of the ventilation system in such labs. We use CFD
analysis to validate the effectiveness of ventilation systems and compliance to the applicable
standards and codes (ASHRAE, NFPA, OSHA) at design stage.
During a typical study of contaminant behaviour, following parameters for indoor air quality are
analysed:
 Local Air Quality Index (LAQI), Local Mean Age of Air (LMA)
 Contaminant Travel Path, Relative Humidity, Temperature
