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

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

4 March 2009 UCOP Safety Meeting 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

5 March 2009 UCOP Safety Meeting 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

6 March 2009 UCOP Safety Meeting Causes of IAQ Problems  Temperature and/or Humidity  Too Much Glare  Inadequate Fresh Air - Lead to Carbon Dioxide (CO 2 ) Buildup –Normal Outdoor CO 2 Levels is 350 ppm –Indoor CO 2 Levels Can Be ppm –> 1000 ppm CO 2 Levels – Tired/Sleepiness –Cal/OSHA Permissible Exposure Limit for CO 2 is 5000 ppm CO 2

7 March 2009 UCOP Safety Meeting 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

8 March 2009 UCOP Safety Meeting 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

9 March 2009 UCOP Safety Meeting 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

10 March 2009 UCOP Safety Meeting 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 ppm

11 March 2009 UCOP Safety Meeting 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

12 March 2009 UCOP Safety Meeting 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 

13 March 2009 UCOP Safety Meeting 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

14 March 2009 UCOP Safety Meeting 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)

15 March 2009 UCOP Safety Meeting IAQ Issues  If There are IAQ Issues in Your Workplace Contact UCOP Environment, Health, & Safety (EH&S) at or Call: –Larry Wong, EH&S Program Manager, at –Ed Baylosis, EH&S Director, at
