SECTION 9: Posting, labeling,
Tagging, and Signaling Requirements
Posting of Required Documents in Buildings (top)
The Nuclear Regulatory Commission
and the State of New Jersey require
that certain documents must be conspicuously posted in a sufficient
number of places that individuals who are engaged in work with "Sources
of Radiation" can observe the documents on their way to or
from locations in which "Sources of Radiation" are used. The
specific documents to be posted vary, depending on whether the "Sources
of Radiation" used in that location are regulated by the Nuclear
Regulatory Commission (NRC) or by the State of New Jersey and under
which license the "Authorized
Users" in that location operate. These documents include:
- Form NRC-3, "Notice to Employees"
- Form BRP-D14, "Notice to Employees"
- Additionally, the following documents need not be posted but a notice
must be posted which describes the documents and states where they
may be examined:
- "CFR Part 19" and "10
CFR Part 20"
- New Jersey Radiation Protection Code
- Princeton University Radiation Safety Guide
- NRC Broad License #29-05185-24, NRC License #SUD 381, NRC License
#SNM 356, NRC Broad License #29-05185-25, and/or New Jersey License
#80066
Posting of Required Documents in Laboratories
(top)
The following documents must be posted within a laboratory in which
"Sources of Radiation" are used. The Office of Environmental
Health and Safety will supply the "Authorized User" with these
posters during the authorization process or machine registration process.
- EHS-HP Form #400, "Accident Procedures and Emergency Phone
Numbers"
- EHS-GS Form #31, "Emergency Information"
Design Specifications for Signs, Labels, Tags,
and Signals (top)
All signs, labels, tags, and signals, used to indicate the presence
of "Sources of Radiation" or to post an area as a "Radiation
Area," "High
Radiation Area," or "Airborne
Radioactivity Area" must conform with "10
CFR Part 20" or the New Jersey Radiation Protection Code as
appropriate. Caution: Some commercially available items may not meet
specifications.
Posting of Radiation Areas (top)
1. Each "Radiation Area" as defined in Section 2 shall be
conspicuously posted with a sign or signs bearing the radiation symbol
and the words:
2. Each "High Radiation
Area" as defined in Section 2 shall
be conspicuously posted with a sign or signs bearing the radiation symbol
and the words:
NOTE: Access to "High Radiation Areas" shall be interlocked
in such a manner that: 1) the radiation level is reduced to the point
that the person(s) entering the area might receive a deep dose equivalent
of 100 mrem in one hour at 30 centimeters from the radiation source
or from any surface that the radiation penetrates, or 2) a visible
and/or audible signal shall make the individual and the supervisor
of the activity (experiment, radiation producing machine, etc.) aware
of the entry and the existing danger, or 3) the area shall be maintained
locked except during periods when access to the area is required,
with positive control over each entry.
3. Each "Airborne
Radioactivity Area" as defined in Section
2 shall be conspicuously posted with a sign or signs bearing the radiation
symbol and the words:
| CAUTION |
| AIRBORNE RADIOACTIVITY AREA |
Posting of Areas Containing Radioactive Materials
(top)
Each entrance to areas or rooms in which radioactive material is used
or stored in an amount greater than 10 times that listed in Appendix
C shall bear a clearly visible label bearing the radiation symbol and
the words:
| CAUTION |
| RADIOACTIVE MATERIAL |
Labeling of Equipment and Containers (top)
1. Any equipment (vaults, refrigerator, etc.) or container in which
radioactive material is stored or used in an amount greater than that
listed in Appendix C shall bear a durable, clearly visible label bearing
the radiation symbol and the words:
| CAUTION |
| RADIOACTIVE MATERIAL |
This label shall, when practicable, also identify the radioisotope,
the amount in Curie units, and the date of the assay. The outside of
a shielded container must also bear this label as well as the inner
container.
2. Labels are not required on laboratory containers such as beakers,
flasks, test tubes, etc., used transiently in laboratory procedures
under supervision or if the concentration of the radioactive material
in the container does not exceed that specified in Table 3, Appendix
B.
3. The radioactive material labels on any empty uncontaminated container
must be removed or defaced prior to disposing of the container or
moving
it to an unrestricted area.
Tagging of "Sealed Sources" (top)
All "Sealed Sources"
shall bear a durable, legible and visible tag permanently attached to
the source. The tag shall be at least one inch square, shall bear the
standard radiation symbol and at least the following:
CAUTION-RADIOACTIVE MATERIAL
DO NOT HANDLE
NOTIFY CIVIL AUTHORITIES IF FOUND |
NOTE: Properly designed tags are available from the Office of Environmental
Health and Safety. If tagging is not feasible or desirable due to source
design, properly inscribed pressure- sensitive tape is also available.
"Radiation Producing Machines and Devices"
(top)
There are special requirements for labels, signs, and signals for "Radiation
Producing Machines and Devices." The details are found in Section
16.
