Indoor Air Quality (IAQ)
March 2009 UCOP Safety Meeting
Indoor Air Quality (IAQ)
 Discuss
Quality
Characteristics of Indoor Air
– Physical
– Chemical
– Biological
 Factors
– Cause IAQ Issues
– Improve IAQ
March 2009 UCOP Safety Meeting
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
 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
 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
 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
 Building
Paints
Remodeling - Adhesives,
– 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 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 CoWorkers
 Building
Air Inlet - Auto Exhaust
– Carbon Monoxide
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
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 0.016 ppm
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
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

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
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)
