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.
