Indoor Air Quality (IAQ)

March 2009 UCOP Safety Meeting

indoor air quality iaq1
Indoor Air Quality (IAQ)
  • Discuss Characteristics of Indoor Air Quality
    • Physical
    • Chemical
    • Biological
  • Factors
    • Cause IAQ Issues
    • Improve IAQ

March 2009 UCOP Safety Meeting

what is iaq
What is IAQ?
  • Office Type Environment
  • Ventilation is General Dilution Type
    • Heating, Ventilating, and Air Conditioning (HVAC) System
    • Windows

March 2009 UCOP Safety Meeting

energy efficiency
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

outdoor make up air for major ucop buildings
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

causes of iaq problems
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

introduction of chemicals contaminants into the building
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

introduction of chemicals contaminants into the building1
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

introduction of chemicals contaminants into the building2
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

introduction of chemicals contaminants into the building3
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

introduction of chemicals contaminants into the building4
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

monitoring for iaq issues
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

monitoring for iaq issues1
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

in summary
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)
