20555 June 12, 1978 IE Bulletin No. 78-07 PROTECTION AFFORDED BY AIR-LINE RESPIRATORS AND SUPPLIED-AIR E00DS Description of Circumstances:
When the Nuclear Regulatory Commission (NRC) 4stablished its current regulations and guidance on acceptable programs for respiratory pro-tection (10 CFR Part 20, 20.103(c) and Regulatory Guide 8.15), it announced its intention to revise the guidance as better information could be obtained and made available. The Los Alamos Scientific information under NRC Laboratory (LASL) has been developing pertinent contract and has submitted a Progress Report on protection factors for air-line supplied-air respirators, LA-7098-PR, and an Informal Report on supplied-air hoods, LA-NUREG-6612-MS.
A.
Air-line supplied-air respirators The report on air-line respirators indicates that the protection provided (protection factor) by certain full facepiece and half-mask facepiece, demand-mode-operated, air-line, supplied-air respirators is significantly less than was previously estimated from the limited information that was available when the protection factors in the current NRC guidance were Specifically, the current published (Regulatory Guide 8.15, Table 1).
guidance lists protection factors of 10 for half-mask facepieces and 50 for full f acepieces that are used with air-line equipment that is The information_in the LASL report operated in the demand mode.
indicates that much of the equipment of this type, even though NIOSH-MESA
- tested and certified, does not achieve a protection factor greater than 5.
The report recoomends that such equipment no longer be certified by NIOSH nor approved by NRC for use.
B.
Supplied-air hoods The report on supplied-air hoods emphasizes the importance of maintaining a minimum air flow of 6 cubic feet per minute (approximately 170 1pm),
and recommends a protection factor of 1,000 at this air flow if calibrated
- National Institute for Occupational Safety and Health-Mining Enforcement and Safety Administration, responsible for respirator certification.
MESA is now designated MSHA, Mining Safety and Health Administration.

IE Bulletin No. 78-07 June 12, 1978 2.
If your respiratory protection program includes the use of air-line supplied-air respirators operated in the demand mode (not respirators operated in continuous-flow or pressure-demand modes), determine the manufacturer, model and number of half-mask and full facepiece equipment used in this mode.

Report in writing within 60 days the information required in items 1 and 2, if applicable. Reports are to be submitted to the Director of the appropriate NRC Regional Office listed in Appendix D of 10 CFR Part 20 and a copy forwarded to the Director, Division of Fuel Facilities and Materials Safety Inspection, U.S.
