Proper ventilation is important for maintaining good indoor air quality as well as to control dusts, mists or fumes that may be produced during an industrial or construction activity. In addition to conducting indoor air quality evaluations, we can assist with basic to some advanced assessments of the ventilation system performance. 
 
Operational parameters of quantity and velocity can be evaluated and compared to design criteria or to recommended practices for industrial ventilation as defined by the American Conference of Governmental Industrial Hygienists (ACGIH). Regular chemical fume hood or paint booth evaluations for adequate ventilation are recommended and in some cases required by OSHA regulations. American Society of Heating, Refrigeration and Air-Conditioning Engineers (ASHRAE) provides several indoor air quality parameters and recommendations for air-exchange rates.

We have also assisted manufacturers in new development evaluations as it relates to control of pathogens by ventilation-related technologies.

In light of the COVID pandemic, we have utilized veriDART® which utilizes a tagged DNA particle to evaluate the dilution and reduction atmospheric concentrations following a simulated release. This can assist in evaluating effectiveness and efficiency of the ventilation system. Often ventilation assessments are combined with other services to assess exposure concentrations of a chemical or to evaluate indoor air quality complaints.
