NIOSH Comments on the U.S. Coast Guard's Notice of Proposed Rulemaking on Updating Approval and Carriage Requirements for Breathing Apparatus and Gas Masks by J. D. Millar, October 26, 1990

摘要

The testimony concerns the view of NIOSH in support of the Coast Guard in promulgating a proposed rule for updating approval and carriage requirements for breathing apparatus and gas masks. NIOSH agrees that only positive pressure self contained breathing apparatus (SCBA) should be allowed for fire fighting or in immediately dangerous to life or health atmospheres. NIOSH also supports the suggested update in regulatory language that would require use of Mine Safety and Health Administration/NIOSH approved respirators. Where respirators on marine vessels may be used in confined spaces, NIOSH recommends that the Coast Guard select respirators in accordance with NIOSH recommendations. NIOSH also submits with the testimony a NIOSH Alert regarding the prevention of death from excessive exposure to chlorofluorocarbon-113 (76131).
