03/06/2023 - 03/07/2023: Ventilation Assessment Using Balometers, CO2, and PM 2.5

Monday, March 6 - Tuesday, March 7, 2023 | 8 AM - 5 PM

Instructor David Moore, CIH, uses a balometer to collect ventilation data, and generates CO2 to assess air exchange

Ventilation is an essential engineering control for optimizing indoor air quality and minimizing the impact of wildfire smoke events, climate change exacerbated allergies, COVID-19 surges and variants, and in preparing for future pandemics. This in-person, hands-on training will review the basics of assessing ventilation at the occupant level, and help you identify a framework to identify and address ventilation vulnerabilities. 

During the workshop, learners will use balometers to collect and analyze data, and to calculate air changes per hour. Learners will also receive hands-on training on how to use CO2 and PM 2.5 to assess air exchange for risk mitigation. Real-world ventilation assessment data will be leveraged to identify recommendations in alignment with CDPH Interim Guidance for Ventilation, Filtration, and Air Quality in Indoor Environments; ASHRAE; the Cal/OSHA Protection from Wildfire Smoke Standard; and the Cal/OSHA Non-Emergency COVID-19 Prevention Regulations. Strategies for communicating risk to improve psychological and physical safety, and to guide organizations as they navigate in-person work challenges will also be discussed. 

Course Format

This course will be taught in-person at the Richmond Field Station, Berkeley Global Campus.


This educational activity is intended for occupational health and safety professionals including industrial hygienists, certified safety professionals, registered environmental health specialists, those performing indoor air quality assessments, and others involved in assessing ventilation as part of a multi-layered approach for optimizing office and school building indoor air quality.
