Areas surrounding the danger area must be controlled during emergencies by prohibiting unauthorized personnel from entering the emergency release area. Methods of excluding areas and defining various zones need to be addressed in the ERP.
Emergency responses are coordinated from a command post a safe distance away from the emergency release area. The way this command post is assembled and its functions must also be addressed in the ERP. (1910.120 Appendix C, Section 7 provides further guidance).
Personnel expected to set up boundaries designating safe and unsafe areas must be trained to the first responder operations level. An employee trained to the first responder awareness level may not set up safe distances because they lack knowledge regarding the potential for exposure, explosion, or radiation. Once these areas have been established, first responder operations level personnel must control entry and exit from the area of the release. (Note: Awareness level trained personnel may assist in preventing unauthorized entry into the area of the release providing all of their activities are done at a safe remote location.)
If the ERP does not designate equipment, people, and procedures to ensure site security and control, cite (q)(2)(v). Failure to properly train employees consistent with their roles in supporting site security and control shall be cited under 1910.120(q)(6).
