Indoor air quality iaq

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)

March 2009 UCOP Safety Meeting
