Air sampling may have one or more of what six objectives?
- 1. identify air contaminant
- 2. estimate employee exposures
- 3. characterize an environment generally
- 4. identify and quantify emission sources
- 5. check the effectiveness of emission and exposure controls
- 6. check for compliance with standards
Air sampling may be categorized in what three ways?
- 1. Location (personal, breathing zone, area, source, stack)
- 2. Time-span (continuous, short-term, grab)
- 3. Type (indicator tube, charcoal tube, filter, impinger, dosimeter badge)
How is air sampling properly conducted?
Use one of the prescribed methods written by NIOSH, OSHA, or other recognized sampling/analysis authority.
Statistical consideration questions should include:
- Where, when, and whom to sample?
- How many samples are necessary?
- How long to sample?
- How significant are the results obtained?
General approach to air sampling is what?
Generally, one obtains a representative sample or random samples (for average exposures or air concentrations). Often, the person or location with the highest potential exposure or concentration is sampled to provide worst case data.
What are the 9 steps to air sampling?
- 1. Characterize air contaminates
- 2. Determine appropriate sampling/analytical methods
- 3. Obtain sampling materials/equipment
- 4. Assemble equipment and calibrate
- 5. Conduct air sampling
- 6. Perform post-calibration
- 7. Establish chain of custody
- 8. Perform Analysis
- 9. Report and followup
