using phase contrast microscopy (PCM) ANSWER a.
2. When can worker air sampling be skipped? ANSWER: When workers are
wearing SARs that are operating in positive pressure mode
What is the PEL, or Permissible Exposure Limit? 0.1 f/cc per 8-hour TWA is

10. School air samples are analyzed using TEM because - ANSWER It can
resolve fibers that could be undetectable under PCM and is mandated by
