Conduct open source internet search and consult NCMI, USAPHC, global threat assessment program (GTAP), United Nations environmental program (UNEP), International Atomic Energy Agency (IAEA), and SECRET Internet Protocol Router Network (SIPRNET) resources.

Service preventive medicine personnel will fill out the JS OEHSA template during Phase I and II of the OEHSA process. 2. Health risk communication to local commanders, medical authority, etc., is accomplished throughout the OEHSA process as new OEH threat information is ascertained. Figure 1-3.

During these predeployment activities, Service preventive medicine personnel should begin completing the JS OEHSA template, developing a preliminary CSM, and formulating a PLHA and courses of action to take upon arrival at the deployed location. 2.2 PREDEPLOYMENT ACTIVITIES The primary objective of the predeployment activities is to conduct a PLHA and build a preliminary CSM for the deployment site. Service preventive medicine personnel should make a substantial effort to identify as many of the potential OEH threats associated with on- and off-site sources prior to deploying to a location. This is the beginning of the OEHSA process and the initial stages of building a CSM. It can be reasonably expected that existing OEH information may be limited, depending on current or past operations conducted at the location. However, an extensive search to obtain general information concerning the location should be accomplished. The list provided below identifies some typical questions that Service preventive medicine personnel should a to answer during predeployment activities. The
