SUPPLEMENTARY INFORMATION:

Background

On November 15, 1994, OSHA published proposed revisions to 29 CFR 1910.134, the Respiratory Protection standard (59 FR 58884). After announcing an extended comment period on the proposal, OSHA held public hearings on the proposal from June 6-20, 1995 (60 FR 15263). One of the issues discussed extensively during this rulemaking is setting assigned protection factors (APFs) for the various respirator classes. To assist OSHA and the public in evaluating the record on this issue, OSHA contracted with Dr. Mark Nicas to prepare recommendations for evaluating protection factor studies and combining information across studies for use in setting APF values. Dr. Nicas submitted a report titled "The Analysis of Workplace Protection Factor Data and the Derivation of Assigned Protection Factors" (hereafter, the "Nicas Report") which was timely entered as a post-hearing comment into the Respiratory Protection Docket H-049 as Exhibit #156. OSHA is contemplating using the recommendations presented in the Nicas Report as an aid in setting APFs for the final Respiratory Protection standard.

Request for Review and Comments

The post-hearing briefing period recently ended on October 20, 1995. OSHA is interested in giving the public an additional opportunity to comment on the Nicas Report. Accordingly, OSHA is reopening the record for the Respiratory Protection standard solely to provide a further opportunity to review the Nicas Report and to submit such comments on the recommendations proposed. The Nicas Report recommends approaches to resolving key science-policy issues related to setting APFs. These issues include deciding which workplace protection factor studies should be evaluated; accounting for particle size effects, respiratory deposition, and below-detection-limit values; and requiring specific statistical analyses to account for between-wearer variability in respirator performance, within-wearer variability, between-study variations, and parameter uncertainty.

OSHA requests that reviewers comment on the appropriateness and completeness of the issues identified, the statistical methodology recommended, and the solutions offered for the other issues. OSHA also would appreciate any additional opinions or information that reviewers may want to submit regarding statistical methodologies and evaluation criteria for APF studies.
