Static electricity is a major hazard during fueling, but modern fuel dispensers include multiple safety features to prevent sparks. Dispensers are grounded to discharge static into the earth, and hoses are made with conductive materials to avoid static buildup.
Nozzles are designed with bonding systems that keep the dispenser and vehicle at the same electrical potential. By controlling static, a fuel dispenser ensures safe fueling even in dry environments where static is more likely to occur.
