Abstract
A fueling environment's safety is improved by adding static charge sensors to the fuel dispenser and its peripherals. The static charge sensors detect static charge proximate the fuel dispenser and provide an indication of the static charge to a threshold detector. If the static charge is above a predetermined threshold, one or more safety devices may be activated to disperse or reduce the amount of hydrocarbon vapors proximate the fuel dispenser. Reduction in the amount of hydrocarbon vapors proximate the fuel dispenser helps reduce the risk of harm from the static charge.
