Failure Report No. S364.
NIOSH :10 pages
Test results using the NIOSH analytical method S364 for fluorine (7782414) are reported. The method involves collection in a midget impinger containing sodium-hydroxide (1310732) preceded by a hydrogen-fluoride (7664393) scrubber containing sodium-fluoride (7681494), pellets, and analysis by colorimetry and spectrophotometry. Analytical procedures and reagents are described along with generation of the test atmosphere. Recovery rate data is included. The method was unsatisfactory due to poor recovery rates at high humidity, probably due to hydrolysis of the sodium-fluoride in the scrubber.
