Possible radio frequency hazard.
1 Safety Considerations and Requirements
NGSLR is operated under the approval of the Occupational Safety and Health Division (OS&H) at the NASA
Goddard Space Flight Center and follows all guidelines and requirements established by that office and the
American National Standards Institute (ANSI). Because of the system s proximity to multiple airports in the
Baltimore/Washington DC corridor, the Goddard Laser Safety Office has mandated additional requirements in
cooperation with the Federal Aviation Administration (FAA). These include notification of the National Capital
Regional Coordination Center (NCRCC) before and at the conclusion of scheduled laser operations for the week.
The NGSLR and LRO laser ranging programs use a combination of procedures, electromechanical systems, and
software to ensure SLR operations are safe. Both systems offer multiple verifications and redundancies to make
certain the operations of the system are properly conducted. In addition, all system users are required to
comply with the procedures and requirements listed in the NGSLR Safety Manual, the NGSLR Operations
Manual, the LRO Operations Manual and the NGSLR System Alignment, Focus and Maintenance Manual.
1.1 Electrical Hazards
Warning: Employees are not permitted to work on any electrical equipment when alone;
there is always a two person rule in effect. Where possible, the power supply should be
locked out and reduced to a zero energy state.
Instrumentation and equipment in the NGSLR shelter have no electrical hazard other than the standard 120V /
20A service that runs these devices.
1.2 Radio Frequency Hazards
Warning: Personnel are prohibited from being on the radar tower while the LHRS is in
operation, due to possible exposure to elevated levels of microwave radiation. The system
must be powered off and locked out prior to maintenance being performed.
Personnel on any adjacent structure should be a minimum of 10 feet away from the radiating antenna in order
to minimize exposure to RF energy. Though this distance is a minimum safe distance, exposure to all RF radiation
should be avoided whenever possible.
