U.S. NUCLEAR REGULATORY COMMISSION OFFICE OF IfiSPECTION AND; ENFORCEMENT REGION III June 12, 1978 IE Bulletin No. 78-07 PROTECTION AFFORDED BY AIR-LINE RESPIRATORS AND SUPPLIED-AIR HOODS Description of Circu=scances:
When the Nuclear Regulatory Co= mission (NRC) established 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 Laboratory (LASL) has been developing pertinent information under NRC 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, de=and-= ode-operated, air-line, supplied-air ' respirators is significantly less than was previously estimated from the'11mited informaticn thLt was
~
available when the protection factors in the current NRC guidance were published (Regula, tory Guide 8.15, Table 1). Specifically, the current guidance lists protection f actors of 10 for half-mask facepieces and 50 for full. f acepieces that are used with air-line equipment that is operated in the demand mode. The information in the LASL report indicates that much of the equipment of this type, even though NIOSH-MISA* tested and certified, does not achieve a protection factor greater than 5.
The report recoc= ends 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 1701pm),
and recommends a protection factor of 1 000 at this air flow if calibrated 3
