Keep a 300-foot buffer between fueling operations and radar equipment. This distance reduces the risk that fuel vapors, which can travel with air currents or pool near the ground, reach the radar area where ignition sources or electrical equipment could ignite them. It also gives space to manage a potential spill without exposing the radar or personnel to danger and helps prevent static discharge or sparks near energized equipment. Distances smaller than this wouldn’t provide adequate clearance for vapor dispersion and ignition risk, while a much larger distance isn’t necessary for standard safety practice.
