The EROS Director’s Office and Facilities Management are dedicated to providing a safe and secure environment for visitors to our facility. The following information is intended to inform EROS visitors of the safety and security requirements to better insure that everyone has a safe and secure visit.

All public visitors’ vehicles and persons will need to be screened prior to being allowed access onto Federal property. All visitors are required to stop at the main gate where you will receive additional instructions.  A parking pass will be issued and you will be directed to the Visitor parking lot.

Upon entrance to the visitor main lobby, you will be processed through a security check point. Only bring in items that are necessary. Cameras and video recorders are allowed inside the facility with some restrictions. Taking pictures outside the Center is not authorized without permission. Animals are not allowed on Federal property unless they are documented working animals with a valid license or certification to do so.
