PART 2 Work Preparation
321 Radiological Work Permits
The RWP is an administrative mechanism used to establish radiological controls for intended work activities. The RWP
informs workers of area radiological conditions and entry requirements and provides a mechanism to relate worker
exposure to specific work activities.
1.
The RWP should include the following information:
a.
Description of work
b.
Work area radiological conditions
c.
Dosimetry requirements
d.
Pre-job briefing requirements, as applicable
e.
Training requirements for entry
f.
Protective clothing and respiratory protection requirements
g.
Radiological Control coverage requirements and stay time controls, as applicable
h.
Limiting radiological conditions that may void the RWP
i.
Special dose or contamination reduction considerations
j.
Special personnel frisking considerations
k.
Technical work document number, as applicable
l.
Unique identifying number
m.
Date of issue and expiration
n.
Authorizing signatures.
2.
The RWP should be integrated with other work authorizations that address safety and health issues, such as those
for industrial safety and hygiene, welding, or confined space entry.
3.
If necessary to ensure appropriate accounting, the RWP number should be used in conjunction with the radiation
dose accounting system to relate individual and/or collective dose to specific activities.
322 Use of Radiological Work Permits
Many facilities find it effective to use two different types of RWPs. General RWPS are used for entry and repetitive work
in areas with known and stable low-hazard radiological conditions. Job-specific RWPs are used for more complex work
and for entry into higher-hazard areas.
1.
RWPs should be used to control the following activities:
a.
Entry into radiological areas
b.
Handling of materials with removable contamination that exceed the values of Table 2-2
c.
Work in localized benchtop areas, laboratory fume hoods, sample sinks, and containment devices that has the
potential to generate contamination in areas that are otherwise free of contamination
d.
Work that disturbs the soil in soil contamination areas
e.
Work that involves digging in underground radioactive material areas
2.
Job-specific RWPs should be u sed to control non-routine operations or work in areas with changing radiological
conditions. The job-specific RWP should remain in effect only for the duration of the job.
