  • 1988 OSHA PEL Project Chlorine NIOSH CDC

    Sep 28, 2011 · In 1986, the ACGIH proposed revising the TLVs for chlorine to 0.5 ppm as an 8 hour TWA and 1 ppm as a 15 minute STEL. This proposal was based on a review of two recent studies. One study, a 1981 doctoral dissertation by Anglen (Ex. 108A), was sponsored by the Chlorine Institute and was conducted on 29 human subjects.Read More
