What is the distance requirement between overhead power lines and fuel dispensers: 5m or 6m?
Thread Content
I would like to ask everyone: Article 4.0.4 of the \"Technical Standards for Automobile Fueling, Gas Refueling, and Hydrogen Refueling Stations\" GB50156-2021 stipulates that the distance between fueling pumps and insulated overhead power lines should be no less than 5 meters, while Article 4.0.12 states that overhead power lines shall not cross the operation areas of automobile fueling, gas refueling, and hydrogen refueling stations. ”According to clause 2.1.18 of this standard: the work area is the explosion hazard zone of the fuel dispenser plus 3 meters (in the case of a fuel vapor recovery system), which amounts to 6 meters. Now the question is, should the 5m distance requirement be enforced? Should the 6m distance requirement still be applied?
According to the Technical Standards for Automobile Fueling, Gas Filling, and Hydrogen Refueling Stations GB50156-2021, the distance between fuel dispensers and insulated overhead power lines must be no less than 5 meters. However, if the definition of the work area is taken into account—that is, the explosion hazard zone around the fuel dispenser plus 3 meters (in the case of a fuel vapor recovery system)—it is necessary to ensure that overhead power lines are at least 6 meters away from the edge of the work area to prevent them from crossing over it. Overall, a stricter 6-meter distance requirement should be implemented to comply with all relevant regulations and ensure safety. .
Thank you. That means there are loopholes in the standards. Do companies currently operating under the old standards need to make immediate adjustments?
