Top 10 Safety Standards to Check for Mobile Filling Stations in 2026

You have selected the site, sized the tank, and chosen a supplier. The mobile filling station is on its way. But there is one question that can shut down your entire operation before a single drop of fuel is dispensed:

Does your equipment meet the safety standards required by your jurisdiction?

In 2026, regulatory compliance is non-negotiable. Mobile filling stations may be temporary, but the safety requirements governing them are not. Local fire marshals, building officials, and environmental agencies enforce these standards—and they will inspect before granting approval to operate.

Here are the top 10 safety standards every mobile filling station must meet in 2026.

1. NFPA 30A – Code for Motor Fuel Dispensing Facilities and Repair Garages

NFPA 30A is the cornerstone of fire safety for any facility that dispenses motor fuel. Published by the National Fire Protection Association, it governs fire and explosion safety at retail service stations, fleet fueling centers, and—critically—mobile fueling operations.

The code applies to "motor fuel dispensing facilities, motor fuel dispensing at farms and isolated construction sites, and on-demand mobile fueling". A dedicated chapter on on-demand mobile fueling was added in recent editions.

Key NFPA 30A requirements for mobile filling stations:

Requirement	Detail
Tank capacity limits	Maximum 12,000 gallons per individual tank; 48,000 gallons aggregate per site
Dispenser location	Minimum 10 feet from building openings
Emergency disconnects	At least one emergency shutoff device within 20–100 feet of each dispenser
Fire extinguishers	Minimum 80-B:C rated extinguisher for Class B and Class C hazards
Spill kits	Minimum 5-gallon spill kit designed to promptly mitigate and dispose of leakage or spills
Bonding	Means for bonding the mobile fueling vehicle to the motor vehicle being fueled

What this means for you: If your mobile filling station dispenses fuel into vehicle tanks anywhere in North America (and in many jurisdictions globally that adopt NFPA standards), NFPA 30A is the baseline standard you must meet.

2. UL 142 – Steel Aboveground Tanks for Flammable and Combustible Liquids

Your fuel storage tank is the heart of the mobile station—and it must be built to a recognized safety standard. UL 142 is the ANSI-accredited standard for steel aboveground tanks for flammable and combustible liquids.

UL 142 covers steel primary, secondary, and diked-type atmospheric storage tanks intended for noncorrosive, stable flammable and combustible liquids with a specific gravity not exceeding 1.0 in aboveground applications. The standard establishes rigorous requirements for:

• Tank design and construction – Steel materials, fabrication methods, welding procedures
• Performance testing – Leakage, hydrostatic strength, top loading, buoyancy, and lift lug tests
• Quality control – Factory testing and production line inspections

UL 142 represents the baseline construction and performance standard for aboveground steel tanks. Tanks can be single-wall, double-wall (secondary), or diked-type configurations.

What this means for you: A UL 142 listing on your tank is not a "nice to have"—it is a requirement for code compliance in most North American jurisdictions. If your supplier cannot produce a UL listing, your equipment may fail inspection.

3. ATEX Directive 2014/34/EU – Equipment for Explosive Atmospheres

If you are deploying a mobile filling station in Europe—or selling to European markets—ATEX certification is mandatory. The ATEX Directive (2014/34/EU) covers equipment used in potentially explosive atmospheres.

ATEX certification means equipment has been fully tested and approved to be safe for use in hazardous or explosive environments. All electrical and mechanical equipment in the fuel dispensing area must be ATEX certified for Zone 1 and Zone 2 operation—including dispensers, transfer pumps, level instruments, lighting, and control panels.

What ATEX covers in a mobile filling station:

• Explosion-proof pumps – Designed to prevent ignition in hazardous zones
• Electrical components – All wiring, switches, motors, and connection boxes must carry Class I, Div 1 or ATEX Zone 0/1 explosion protection ratings
• Control systems – Automation panels and monitoring equipment

What this means for you: If your project is in the EU, or if you are sourcing equipment that may eventually be deployed in the EU, ATEX certification is legally required. Non-compliance can result in rejected equipment, fines, and project delays.

4. IECEx – International Certification for Explosive Atmospheres

IECEx is the global certification system for equipment used in explosive atmospheres. While ATEX is the legal requirement for Europe, IECEx is a voluntary but globally accepted certification that facilitates international trade and deployment.

Both ATEX and IECEx align with the same technical standards (IEC 60079 series), so the safety requirements are essentially identical. The critical difference: IECEx never allows self-certification—every product must be certified by an approved body, making it a more rigorous and internationally trusted mark.

Key IECEx applications for mobile filling stations:

Component	IECEx Requirement
Fuel transfer pumps	Must be IECEx certified for potentially explosive atmospheres
Explosion-proof systems	Flameproof fueling solutions for Zone 1 and Zone 2 hazardous areas
Control and automation	Factory-certified IECEx-compliant panels

What this means for you: For international deployments—especially in the Middle East, South America, and Asia-Pacific—IECEx provides a globally recognized mark of safety. Many buyers now specify IECEx certification alongside or instead of ATEX.

5. CE Marking – EU Conformity for Market Access

CE Marking is the mandatory conformity mark for products sold in the European Economic Area. For mobile filling stations, CE marking indicates compliance with EU safety, health, and environmental protection requirements.

The certification framework for mobile filling stations in Europe typically involves multiple directives:

• Pressure Equipment Directive (PED 2014/68/EU) – For the tank and pressure assemblies
• ATEX Directive (2014/34/EU) – For equipment in potentially explosive atmospheres
• Measuring Instruments Directive (MID 2014/32/EU) – May apply to the dispenser

What this means for you: If you are importing or operating a mobile filling station in Europe, CE marking is not optional—it is the "license to sell". Reputable suppliers will design core components to the highest common denominator (e.g., ATEX and ASME) and manage specific certification logistics for the end destination.

6. ISO 16923:2026 – CNG Fuelling Stations

Published in January 2026, this standard specifies requirements for the design, construction, operation, maintenance, and inspection of stations for fuelling compressed natural gas (CNG) to vehicles.

Key provisions of ISO 16923:2026:

Area	Requirement
Scope	Design, construction, operation, maintenance, and inspection of CNG stations
Applicability	Slow-fill and fast-fill stations; private and public access; fixed and mobile storage (daughter stations)
Multi-fuel	Applies to multi-fuel stations including CNG
Odorization	Based on the condition that gas entering the station is odorized; for unodorized gas, additional safety requirements apply
Exclusions	Does not apply to vehicle-to-vehicle transfer or vehicle refuelling appliances (VRA)

What this means for you: If your mobile filling station handles CNG, ISO 16923:2026 represents the latest international consensus on safety for CNG infrastructure. It supersedes the 2016 version.

7. ISO 16924:2026 – LNG Fuelling Stations

Also published in January 2026, this standard covers stations for fuelling liquefied natural gas (LNG) to vehicles.

ISO 16924:2026 covers all equipment from the LNG storage tank unloading connection up to (but not including) the fuelling nozzle on the vehicle. It applies to stations with the following characteristics:

• Private access or public access (self-service or assisted)
• Metered and non-metered dispensing
• Fixed LNG storage or mobile LNG storage
• Movable fuelling stations and mobile fuelling stations
• Multi-fuel stations

The standard also specifies the design, construction, operation, maintenance, and inspection of fuelling stations using LNG as an onsite source for supplying compressed natural gas (CNG) to vehicles—commonly known as LCNG fuelling stations.

What this means for you: If your mobile filling station handles LNG or operates as an LCNG station, compliance with ISO 16924:2026 is essential. The standard was published in January 2026 and became valid from April 2026.

8. EN 12285-2 – European Standard for Above-Ground Steel Tanks

EN 12285-2 is the European standard for shop-fabricated, above-ground steel tanks for the storage of flammable liquids.

Key requirements:

Area	Detail
Tank types	Single-wall and double-wall (self-bunded) configurations
Materials	Certified carbon steel such as S235JRG2
Construction	Welded steel construction with wall thickness manufactured to EN 12285 standards
Capacity	Up to 100,000 liters (100 m³)
Compliance	Can be designed to EN 12285-2 with NFPA-compliant features

What this means for you: If you are deploying a mobile filling station in Europe, EN 12285-2 certification for the tank is a key requirement. Many manufacturers now offer EN 12285-2 certified tanks as standard for European projects.

9. OIML R 117 – Fuel Dispenser Accuracy and Metrology

OIML R 117 is the international standard for the metrological accuracy of fuel dispensers. It ensures that fuel measurement is accurate and trade-compliant.

Key requirements:

Parameter	Requirement
Accuracy	±0.5% or better under standard operating conditions
High-accuracy builds	±0.2% achievable with precision measurement systems
Flow range	Typically 20–80 L/min (varies by dispenser type)
Certification	Requires OIML certificate and compliance with Legal Metrology Act

Modern fuel metering devices can achieve measurement accuracy reaching ±0.25%, fully compliant with OIML R117 international standards.

What this means for you: If your mobile filling station dispenses fuel for commercial purposes—where every litre must be accurately accounted for—OIML R117 certification ensures trade-grade accuracy and protects you from measurement disputes and regulatory penalties.

10. IEC 60079 Series – Explosive Atmospheres – Electrical Installations

The IEC 60079 series is the foundational international standard for electrical equipment in explosive atmospheres. It covers the design, selection, installation, and inspection of electrical installations in hazardous areas.

Key parts relevant to mobile filling stations:

Standard	Content
IEC 60079-0:2026	General requirements for construction, testing, and marking of Ex Equipment
IEC 60079-14:2026	Design, selection, installation, and initial inspection of electrical installations of Ex Equipment

The standard applies to all electrical Ex Equipment including fixed, transportable, portable, and personal equipment, and installations—permanent or temporary.

What this means for you: All electrical components in a mobile filling station—pumps, motors, dispensers, control panels, lighting, and sensors—must comply with IEC 60079 requirements. The 2026 edition of the standard was published in February 2026.

Choosing the Right Standards for Your Project

Not every standard applies to every project. Your certification requirements depend on:

Factor	What to Consider
Deployment location	North America → NFPA 30A + UL 142; Europe → ATEX + CE + EN 12285-2; International → IECEx + IEC 60079
Fuel type	Liquid fuels → NFPA 30A, UL 142, EN 12285-2; CNG → ISO 16923:2026; LNG → ISO 16924:2026
Market requirements	Some buyers specify IECEx for global consistency, regardless of location
Local AHJ	Always check with the Authority Having Jurisdiction—they may have additional requirements

Red Flags to Watch For

Before placing your order, verify that your supplier can provide:

• Documented NFPA 30A compliance (if applicable)
• UL 142 listing for the tank (or equivalent recognized standard)
• ATEX or IECEx certification for all electrical equipment
• CE Marking (if deploying in Europe)
• Compliance with ISO 16923:2026 or ISO 16924:2026 (if handling natural gas)
• EN 12285-2 certification (if deploying in Europe)
• OIML R 117 compliance for dispensers
• IEC 60079 compliance for all electrical installations
• Third-party inspection reports from recognized organizations (SGS, Bureau Veritas, TUV)

If a supplier cannot provide documented certifications for every applicable standard, walk away. Compliance is mandatory regardless of how long the station remains on site.

The Bottom Line

In 2026, mobile filling stations are no longer a regulatory gray area. NFPA 30A, UL 142, ATEX, IECEx, CE, ISO 16923:2026, ISO 16924:2026, EN 12285-2, OIML R 117, and IEC 60079 provide a clear framework for safe design, construction, and operation.

The standards exist to protect your people, your equipment, and your project. Meeting them is not optional—it is the price of admission.

Choose a supplier who builds to these standards as a matter of course, not as an expensive afterthought. Your project timeline—and your peace of mind—depend on it.
