DOE-STD-1128-98
C.6.2
Breathing Air
For facility design, confinement of airborne radioactive materials should be the
required method of preventing internal deposition of radioactive particulates.
However, during operation and maintenance of the facility, situations may occur
(accidents, special maintenance, spill recovery, etc.) for which air-supplied
respiratory protection is required.
A plutonium facility should be provided with a system that is capable of supplying
breathing air to a number of workstations in each occupied area where the
following conditions exist:
-- Gaseous or airborne radioactive material may cause occupational exposure
limits of 10 CFR 835 to be exceeded;
-- potentially dispersible plutonium compounds exceeding 100 mg are handled
outside of containment devices; or
-- personnel may be required to enter cells or other areas that contain large
amounts of loose radioactive material for repair, maintenance,
decontamination, or operation.
Breathing-air systems may be portable or semi-portable bottled systems or installed
compressor systems. The facility design requirements should be determined by the
system selected.
Breathing-air supply systems should meet the requirements of ANSI Z88.2-1980,
Practices for Respiratory Protection (ANSI, 1980b) and 29 CFR 1910 (most recent
revision) (DOL, 1993). Air-line connections for the breathing air must be unique to
preclude connecting other gas supplies to the breathing-air lines. Additional criteria
for design of breathing-air systems found in the references mentioned above should
be considered.
C.6.3
Personnel Monitoring
The facility design should provide for location of personnel monitoring devices in
the vicinity of the workplace. To minimize the potential spread of radioactive
contamination, personnel survey instruments should be available at suitable
locations within the process area, such as for personnel exiting from glove boxes, at
bag-out stations, and at exits from compartmentalized facilities. Survey instruments
or monitoring instruments should be available at contamination-control change
rooms and at exits from controlled areas.
C.6.4
Criticality Safety
See Section 7.0 for detailed guidance on criticality safety in a plutonium facility
including criticality alarms and nuclear accident dosimeters.
