Standard Number: | 1910.134(h)(1)(iii) |
[November 2, 1998] Richard Graham Mine Safety Appliances Company 21 Sussex Court Williamsburg, VA 23188 Dear Mr. Graham: This is in reply to your letter, dated October 21, 1998, concerning SCBAs designed so that the exhalation valve is part of the mask mounted second stage regulator. You state that this SCBA does not have an inhalation or exhalation valve in the facepiece. Thus, the regulator is also contaminated by the wearer as evidenced by the presence of moisture inside the regulator when the unit is doffed. You questioned whether the second stage regulator needs to be decontaminated in addition to the actual facepiece when the respirator is used for emergency use. The regulator would need to be cleaned and decontaminated as required by 29 CFR 1910.134(h)(1)(iii). Please note that the standard would require that such respirators meet all other requirements as detailed in the standard, e.g., NIOSH approval, air quality, etc. Please contact this office if we may be of further assistance. Sincerely, KENNETH W. GERECKE Assistant Regional Administrator [Corrected 10/20/06] |
