What are requirements for electrical grid at petrol stations in Vietnam?
Pursuant to Article 11 of the Circular 15/2020/TT-BCT stipulating electrical grid at petrol stations in Vietnam as follows:
1. Regarding above-ground petrol filling stations
a) Safety requirements in design, installation and use of electrical equipment in filling stations must conform to TCVN 5334:2007 Electrical equipment of oil and oil product storage – Safety requirements in design, installation and use.

- Wires and cables must use copper conductor and be insulated by synthesized plastic.
- Cables must conform to technical requirements according to applicable National Technical Regulation.

- In case underground cables are not covered in steel for protection, place the cables in steel tubes (where automobiles and motorcycles passing by above) or plastic tubes (where no automobiles and motorcycles passing by above) or in separate covered trenches filled with sand.
Do not place cables in the same trenches in which fuel transmission lines are placed.
- Cables must be placed underground when they are installed across driveways, work items and intersecting with fuel transmission lines, in this case, the cables must be placed in steel tubes whose ends must protrude 0.5 m from edges of structures.
- In a single cable tube, do not place power transmission cables and lighting cables in the same place with operational cables, information cables and signal cables.

In case breather valves are not included in lightning protection range of surrounding tall structures, install direct strike lightning protection for breather valves by lightning arresters bonded in an equipotential manner. The tip of a lightning arrester must be at least 5 m away from breather valves.
g) In order to satisfy surge and static protection, each steel tank must be welded with at least 2 metal wires connected with surge and static protection grounding system. Grounding resistance of this system must not exceed 10 W.
h) Install grounding devices for static protection of fuel transportation in positions where fuel is loaded into tanks.
i) Safety grounding system must have grounding resistance no more than 4 W. All neutral metallic components of electrical equipment and fuel dispensers must be grounded safely.
- This grounding system must be positioned at least 5 m away from direct strike lightning protection (distance calculated on the ground).
- If safety grounding system is connected with direct strike lightning protection, grounding resistance must not exceed 1 W.
k) Lightning protection and grounding design of petrol filling stations must conform to applicable regulations on lightning protection construction and design for petroleum storage.
2. Regarding floating petrol filling stations
a) Safety requirements in design, installation and use of electrical equipment in filling stations must conform to TCVN 5334:2007.
b) In case power generators are used in petrol filling stations, position the generators outside of hazardous zones. Exhaust pipes of generators must be installed with fire protection system and coated with thermal insulation layer. Areas where power generators are installed must be separated from tanks, storage or points-of-service.
c) Wires and cables used within the filling stations must satisfy following requirements:
- Wires and cables must use copper conductor, be insulated by synthesized plastic and contained in tubes.
- Cables must conform to technical requirements according to applicable National Technical Regulation.
- In a single cable and wire tube, do not place power transmission cables and lighting cables in the same place with operational cables, information cables and signal cables.
- Tubes containing cables must be connected with each other by screw thread. When connecting or branching wires and cables, use explode-proof wire separators and wire connectors.
d) Cables used for automatic devices and communication devices must comply with regulations under Point c Clause 1 of this Article.
dd) Install direct strike lightning protection system for work items within the filling stations. Lightning arresters must be positioned at an elevation that can cover breather valves. In case breather valves are not included in lightning protection range of surrounding tall structures, install direct strike lightning protection for breather valves by lightning arresters bonded in an equipotential manner. Lightning protection system must be inspected on a yearly basis according to applicable regulations and law.
What are regulations on fire prevention and suppression equipment at petrol stations in Vietnam?
Pursuant to Article 12 of the Circular 15/2020/TT-BCT stipulating fire prevention and suppression equipment at petrol stations in Vietnam as follows:
1. Post fire prevention and suppression regulations, fire fighting regulations, fire prohibition sign and mobile prohibition in noticeable and legible places in petrol filling stations.
2. Petrol filling stations must be adequately equipped with appropriate initial fire-fighting facilities as specified under TCVN 3890:2009 Fire safety and firefighting equipment for buildings and constructions - Equipment, placement, examination and maintenance and under this Regulation.
3. Based on fire hazards of substances and materials in each work items of petrol filling stations, equip and install appropriate fire-fighting facilities.
