G A S (H 3)

This item contains radioactive material. All personnel that operate and/or maintain fire control equipment

containing tritium must be aware of the following special precautions and requirements:

Immediately report any suspected lost or damaged tritium fire control equipment to your unit/mission

Radiation Safety Officer (RSO). If your RSO cannot be reached, contact the TACOM-RI RSO (DSN 793-

2965/6228, Commercial (309) 782-2965/6228) during regular duty hours; or call the Rock Island Police Office

at DSN 793-6135 after duty hours.

A. RULES AND REGULATlONS. NRC Form 3 - Notice to Employees and Energy Reorganization Act of

1974 Section 206 must be posted and the following regulations and licenses must be available for review at a

location frequented by all employees or at the installation Safety Office:

(1)

10 CFR Part 19 - Notices, Instructions and Reports to Workers; Inspections.

(2)

10 CFR Part 20 - Standards for Protection Against Radiation.

(3)

10 CFR Part 21 - Reporting of Defects and Noncompliance.

(4)

NRC license and license application.

Copies may be requested or information obtained by contacting the TACOM-RI Safety Office, DSN 793-

2965/6228, Commercial (309) 782-2965/6228, or by visiting TACOM-RI web site at http://tri.army.mil.

B. SAFETY PRECAUTIONS. The radioactive material used in this instrument is tritium gas (H3) sealed

in glass vials. These sources illuminate the instrumentation during night operations. Federal law prohibits

tampering with or removal of the sources in the field. In the event there is no illumination, notify the local

RSO or TACOM-RI RSO. If skin contact is made with any area contaminated with tritium, wash

immediately with soap and water. Notification of the RSO is required.

The beta radiation emitted by tritium is a hazard only if the vial or source is broken. Tritium can be taken

into the body by inhalation, ingestion, or skin absorption/injection. If the vial is broken, the tritium gas will

dissipate into the surrounding air. If released into a confined space such as a storage locker, container,

unventilated room, or military vehicle, the tritium will be absorbed by lungs from inhalation or by skin

through contact with contaminated surfaces. However, the body naturally eliminates absorbed tritium. If

exposed, notification of the RSO is required.

C. IDENTIFICATlON. Instruments containing radioactive self-luminous vials are identified by

means of radioactive warning label (see above). The radioactive material used in this instrument is

tritium gas (H3) sealed in glass vials. These sources illuminate the instrumentation for night

operations.
