Safety at field sites is an integral component of NGEE-Tropics’ research planning and execution. Whereas each partner organization (DOE national laboratories, universities, and other subcontractors) must establish safety requirements for its staff, NGEE–Tropics leadership team will promote discussions of hazards and best practices for fieldwork. As the lead institution for this project, Lawrence Berkeley National Laboratory will establish project-level and site-specific guidelines for fieldwork that all project participants must review and acknowledge.
