The Occupational Safety and Health Administration (OSHA) has published a new “Indoor Air Quality in Commercial and Institutional Buildings” guide.  The 25 page guide is a useful and basic guide that covers Sources of Indoor Air Pollutants, Common Pollutant Categories, Prevention or Control IAQ Problems, and Applicable Standards and Regulations.  The appendices are very useful especially Appendix A: Common Indoor Air Contaminants, which covers carbon monoxide, damp indoor environments, and volatile organic compounds, to name a few, and Appendix C: HVAC System Maintenance Checklist.  The guide is a simple document, very easy to understand, and will be very helpful to a facility director in resolving indoor air quality issues.
