Actually it does. OSHA 1910.95 tells you that the maximum time-weighted average (TWA) noise exposure for 8 hours is 90 dB(A). Based on the instrument standard you quoted, this means the buzzer must emit at least 93 dB(A). See 29 CR 1901.95, Table G-16, http://www.osha.gov/pls/oshaweb/owadisp.show_document?p_table=STANDARDS&p_id=9735 Doug Nix
