Indoor Air Quality (IAQ)

1. Indoor Air Quality (IAQ) March 2009 UCOP Safety Meeting

2. Indoor Air Quality (IAQ) • Discuss Characteristics of Indoor Air Quality • Physical • Chemical • Biological • Factors • Cause IAQ Issues • Improve IAQ March 2009 UCOP Safety Meeting

3. What is IAQ? • Office Type Environment • Ventilation is General Dilution Type • Heating, Ventilating, and Air Conditioning (HVAC) System • Windows March 2009 UCOP Safety Meeting

4. Energy Efficiency • Starting in the 1970’s Buildings were Sealed Up to Reduce Energy Costs • Air Contaminants Trapped • Lack of Outdoor Air • Sick Building Syndrome • American Society of Heating, Refrigeration & Air-Conditioning Engineers (ASHRAE) Standard 62 – Recommends 15 to 20 Cubic Feet per Minute (CFM) of Outdoor Air per Person March 2009 UCOP Safety Meeting

5. Outdoor Make-Up Air for Major UCOP Buildings • Kaiser Building – Built in the 1950’s • 100% Outdoor Make Up Air • No Indoor Air is Recirculated • 1111 Franklin Street • Minimum of 10% Outside Air • Depending on the Outdoor Temperature at Times Up to 60% of Building Air is Outdoor Make-Up Air • Each Morning – Ventilation Turned Up Prior to Arrival of Employees March 2009 UCOP Safety Meeting

6. Causes of IAQ Problems • Temperature and/or Humidity • Too Much Glare • Inadequate Fresh Air - Lead to Carbon Dioxide (CO2) Buildup • Normal Outdoor CO2 Levels is 350 ppm • Indoor CO2 Levels Can Be 600-800 ppm • > 1000 ppm CO2 Levels – Tired/Sleepiness • Cal/OSHA Permissible Exposure Limit for CO2 is 5000 ppm CO2 March 2009 UCOP Safety Meeting

7. Introduction of Chemicals & Contaminants into the Building • Building Remodeling - Adhesives, Paints • Select Low Volatile/Low Toxicity Products • Schedule Work on Weekends/After Hours • Allow Remodeled Area to Off-Gas Prior to Re-Occupation • Temporarily Relocate Employees • Old Food - Forgotten Lunches/Snacks March 2009 UCOP Safety Meeting

8. Introduction of Chemicals & Contaminants into the Building • Cleaners • UCOP Uses Green Seal Cleaning Supplies • Non-Toxic • Not a Skin Sensitizer • Does Not Contain Substances Which Contribute to Poor Indoor Air Quality • If Using a Cleaner - Be Aware of How Your Actions May Impact Your Co-Workers • Building Air Inlet - Auto Exhaust • Carbon Monoxide March 2009 UCOP Safety Meeting

9. Introduction of Chemicals & Contaminants into the Building • Personal Hygiene Products • Perfumes, Deodorants, Cologne • Be Aware of How Your Actions Can Impact Your Co-Workers • Water Leaks/Water Damage • Mold or Mildew • Air Cleaners - Some Use Ozone • May Affect Persons with Pre-Existing Respiratory Problems March 2009 UCOP Safety Meeting

10. Introduction of Chemicals & Contaminants into the Building • Printers/Copying Machines • Can Generate Particulates and Ozone • Ozone – Eye & Respiratory Irritation • Do Not Place in Room with Poor Ventilation • Do Not Point Printer Exhaust at Individuals • Study on Printers: • Ozone Levels: <0.001 ppm to 0.016 ppm March 2009 UCOP Safety Meeting

11. Introduction of Chemicals & Contaminants into the Building • Animal Dander • Brought into the Office on Clothing • Some Persons have Allergic Reactions • Third Hand Smoke • Recent Studies – Tobacco By-Products Can Cling to Hair, Clothing, & Furniture • Be Sensitive to the Needs of Co-Workers March 2009 UCOP Safety Meeting

12. Monitoring for IAQ Issues • Q-Trak Indoor Air Quality Monitor • Temperature and Humidity • Carbon Monoxide • Carbon Dioxide • ppb RAE Detector • Various Chemical Substances Down to the Parts per Billion Range March 2009 UCOP Safety Meeting

13. Monitoring for IAQ Issues • Chemical Hazards • Do Not Use Odor as an Indicator of Hazard • Certain Individuals May Be More Susceptible to Certain Chemicals • All Chemicals Do Not Have a Permissible Exposure Limit March 2009 UCOP Safety Meeting

14. In Summary • Certain Individuals May Be More Susceptible to Certain Chemicals • Be a Good Neighbor/Co-Worker • Don’t Be Afraid to Ask & Do Not Be Offended If a Co-Worker Asks • Discuss IAQ Issues With Your Supervisor, Department Safety Officer, or UCOP Environment, Health and Safety (EH&S) March 2009 UCOP Safety Meeting

15. IAQ Issues • If There are IAQ Issues in Your Workplace Contact UCOP Environment, Health, & Safety (EH&S) at ehs@ucop.edu or Call: • Larry Wong, EH&S Program Manager, at 510-987-9772 • Ed Baylosis, EH&S Director, at 510-987-0170 March 2009 UCOP Safety Meeting
