Dear Mr. Elliott:
This is in response to your request for an evaluation of an asbestos sampler, the Bellmouth cassette. We have reviewed the materials you submitted to Mr. Daniel Crane of my staff.
The Occupational Safety and Health Administration (OSHA) is a regulatory agency responsible for assuring safe and healthful conditions in the workplace. OSHA does not test, endorse, or promote goods and services of any kind. OSHA [standard] 29 CFR 1910.1001(d)(6)(ii)
- Replicate exposure data used to establish equivalency are collected in side-by-side field and laboratory comparisons;
- The comparison indicates that 90% of the samples collected in the range 0.5 to 2.0 times permissible limit have an accuracy range of plus or minus 25 percent of the ORM results with a 95% confidence level as demonstrated by a statistically valid protocol; and
- The equivalent method is documented and the results of the comparison testing are maintained.
This response is not an approval or endorsement of the Bellmouth asbestos sampler.
Patricia K. Clark, Director
[Directorate of Science, Technology, and Medicine]
