2. PowerPoint ® Presentation Chapter 5 Handheld Meter Testing IAQ Complaints Measurement and Testing Air Properties Handheld Meter Testing for Contaminants

3. Chapter 5–Handheld Meter Testing A facility procedure should be followed when responding to possible IAQ complaints.

4. Chapter 5–Handheld Meter Testing Certain conditions and contaminants can be measured easily with basic test instruments.

5. Chapter 5–Handheld Meter Testing Direct-reading test instruments are the instruments of choice for IAQ complaint investigations due to their mobility.

6. Chapter 5–Handheld Meter Testing Direct-reading IAQ test instruments are usually calibrated every month but some test instruments only require calibration once a year.

7. Chapter 5–Handheld Meter Testing Written quality assurance plans contain the data acquired by measure- ments performed with IAQ test instruments.

8. Chapter 5–Handheld Meter Testing The measurement of basic air properties, in addition to contaminants, provides a baseline for the general condition of air quality within a building.

9. Chapter 5–Handheld Meter Testing Some IAQ test instruments can display several measurements simultaneously.

10. Chapter 5–Handheld Meter Testing An anemometer is used to measure the airflow rate in cubic feet per minute (cfm) to grills and from registers.

11. Chapter 5–Handheld Meter Testing A flow hood is a device that can be used to measure the air volume in cubic feet per minute from diffusers.

12. Chapter 5–Handheld Meter Testing Chemical smoke tests help determine how airflow is moving inside a space or between spaces.

13. Chapter 5–Handheld Meter Testing No official federal standards have been set for permissible levels of nitrogen dioxide; however, some basic exposure limits have been set by various agencies.

14. Chapter 5–Handheld Meter Testing Nitrogen dioxide monitors measure the amount of nitrogen dioxide in an air sample in parts per million (ppm).

15. Chapter 5–Handheld Meter Testing Several severe health symptoms may result when exposure limits of carbon monoxide are exceeded.

16. Chapter 5–Handheld Meter Testing Carbon monoxide meters measure the amount of carbon monoxide in an air sample in parts per million (ppm).

17. Chapter 5–Handheld Meter Testing Some carbon dioxide exposure limits have been set by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE).

18. Chapter 5–Handheld Meter Testing Carbon dioxide measurement test instruments and procedures are similar to carbon monoxide measurement procedures.

19. Chapter 5–Handheld Meter Testing The EPA has set permissible ozone limits for indoor building spaces.

20. Chapter 5–Handheld Meter Testing Ozone meters measure the amount of ozone in an air sample in parts per million (ppm).
