L. DiBerardinis noted he sent several drafts of ANSI Z9.5 to NFPA for comment. No comments have been received so far. The subcommittee will attempt to get input but will move forward unaware of the NFPA concerns. They will seek consistency and conflict resolution between Z9.5 and NFPA 45 where possible. G. Knudson suggested piping acid cabinet exhaust directly into the duct.
Clear direction is needed on tracer gas testing for health reasons.
Suggestions were made to strengthen section 8 of the Z9.5 standard. D. Scarborough suggested a recommendation to move laboratory exhaust fans outside laboratory buildings. Discussion centered on using this format for all ANSI Z9 standards in the future and the advantages or disadvantages of that approach. Issues discussed were related to display of contents, ease of understanding, readability, and consistency with the trend in ISO and other international standards to move to a two column style. P. Schilling moved to continue the 2-column format for the ANSI Z9.5 standard and publish the revised version this way.
