OSHA Respirator Requirements for Selected Chemicals | NIOSH | CDC Revisions to the OSHA Respiratory Protection Standard (29 CFR 1910 134) became effective on April 8, 1998 Incorporated within the preamble of this ruling were changes to OSHA regulations for several chemicals or substances, which are listed as subheadings in blue text throughout this appendix
HYDROCARBONS, AROMATIC 1501 APPLICABILITY: This method is for peak, ceiling, and TWA determinations of aromatic hydrocarbons Interactions between analytes may reduce breakthrough volumes and affect desorption efficiencies Naphthalene, originally validated in S292 [4], failed to meet acceptable desorption efficiency recovery and storage stability criteria at the levels evaluated in this study However, the application
BENZENE by portable GC 3700 a Photovac 10S portable GC Certified standard gas mixtures of benzene in air were obtained from Scott Specialty Gases Inc , and these were used to esta lish the calibration graph Once this graph was established, bias was assessed by analyzing a bag sample containing an unknown concentration and comparing the concentration obtained with that
