TM 9-254
a.
Personnel handling the device should wear rubber or latex gloves. Device must be immediately double
wrapped in plastic, sealed, packaged and evacuated to depot. Outside package must be identified as "Broken Tritium
Device - Do Not Open". Dispose of used gloves as radioactive waste, per instructions from local RPO and wash hands
well.
b.
Personnel who may have handled the broken tritium device should report to health clinic for tritium bioassay.
Optimum bioassay sample is at least four hours after exposure.
c.
Broken tritium sources indoors may result in tritium contamination in the area, such as a work bench or table.
The area must be cordoned off, restricted until wipe tests indicate no contamination.
6.
Training: Installations that use, maintain or store tritium devices must appoint a Radiation Protection Officer
(RPO). The RPO must have at least 8 hours training specifically in handling tritium devices and emergency procedures.
Personnel who use tritium devices must receive one hour basic radiation safety training and General Support (GS)
personnel in tritium device repair facilities will have at least four hours training in hazards of tritium, handling tritium devices
and emergency procedures.
7.
Maintenance: Tritium device repair facilities must have local standard operating procedures (SOPs) that
incorporate the following safety procedures:
a.
General Support (GS) personnel who work in the area will have a baseline bioassay as a minimum.
b.
GS maintenance will store spare tritium parts in separate, non-occupied and well-ventilated storage area.
c.
Porous work benches (e.g., wood) on which tritium devices are repaired will be covered with Kraft paper to
prevent build up of tritium contamination. Replace paper at least once a quarter.
d.
Wipe tests will be taken of general support maintenance facilities at least quarterly with records kept of
analysis.
e.
Removal of the radioluminous source or maintenance on a non-illuminated device is prohibited except at
authorized depots.
f.
“No eating, drinking, smoking or applying cosmetics" signs will be posted in tritium device work areas.
8.
Identification: Radioactive self-luminous sources are identified by means of radioactive warning labels (as above).
These labels should not be defaced or removed, and should be replaced immediately when necessary.
9.
Posting notices: The Nuclear Regulatory Commission Form NRC-3 "Notice to Employees," will be posted at the
main entrance to areas where radioactive materials or other sources of radiation are used, stored, and repaired. Copies of
Form NRC-3 are available from the local RPO.
