When I first started working in the LPG fueling station supply industry 12 years ago, I thought restrictions at these facilities were just about the obvious ones—no smoking, no open flames, that kind of thing. Over the years, as we’ve installed stations across residential areas, truck stops, and commercial fleets, I’ve learned the restrictions go far beyond basic safety rules. As a supplier who works hand-in-hand with station owners and operators, I’m here to break down what those restrictions actually are, why they matter, and how we design our station solutions to help operators stay compliant without feeling like they’re working against a list of random rules. LPG Fueling Station
Let’s start with the most fundamental restrictions, and these are non-negotiable for good reason. First and foremost, you can never bring an open flame within 10 meters of an LPG fueling point. I’ve seen too many near-misses—one operator we worked with almost had a disaster when a customer lit a cigarette before pulling up to the pump. LPG vaporizes at room temperature, and when it’s denser than air (which it is, by the way—about 1.5 times heavier than air), it can pool in low spots like under a truck or a concrete slab. A single spark from a cigarette, a phone call (we restrict mobile phone use within the same 10-meter zone for that reason), or a faulty electrical connection can ignite that cloud. Our station equipment is built with explosion-proof components specifically to mitigate this, but even the best equipment can’t override human error, which is why that distance rule is so strict.
Then there’s the restriction on refueling non-LPG compatible vehicles. This one comes up a lot, especially at stations that serve both passenger cars and commercial trucks. LPG is a fossil fuel, but it’s not the same as gasoline or diesel. Using LPG in a gasoline-only vehicle can damage fuel injectors, fuel lines, and catalytic converters because LPG has different combustion properties. Conversely, putting gasoline or diesel in an LPG vehicle can clog fuel filters, cause engine misfires, and even lead to leaks. As a supplier, we include clear labeling on every pump we install—bold, high-visibility signs that say “LPG ONLY” and list compatible vehicle types. We also work with operators to train their staff to ask for vehicle type before starting refueling, though we’ve seen that over-enthusiastic labeling is better than under-labeling here.
One area that many first-time station owners don’t realize is restricted is the type of containers you can refuel. For transportable LPG cylinders—like the ones used for grills, forklifts, or portable generators—there are specific rules. You can only refuel cylinders that are properly certified, in good condition, and designed for LPG use. Cylinders with dents, rust, or expired certification tags can’t be refueled because they’re at risk of rupturing under pressure. We work with stations to install cylinder inspection stations right next to the fueling points, so operators can quickly check cylinders before refueling. Another key restriction: you can’t overfill a cylinder. LPG expands when heated, so most stations are required to leave 10-15% of the cylinder’s volume empty to allow for expansion. Our fueling systems have automatic shutoff sensors that trigger when the cylinder reaches that safe fill level, which takes the guesswork out for operators and prevents overfilling.
Location restrictions are another big one, and they vary by region, but there’s a consistent set of guidelines across most countries. LPG stations can’t be built too close to certain types of structures—like schools, hospitals, or residential buildings in densely populated areas. The exact distance depends on station size; a small private station for a fleet might only need 5 meters of clearance from a property line, while a public station serving heavy trucks might need 20 meters or more. As a supplier, we conduct site assessments before installing any equipment to make sure the planned location meets all local zoning and safety regulations. We also provide operators with documentation to submit to local fire marshal offices for inspection, which is a step many new operators struggle with—we make sure that paperwork is accurate and complete so they don’t run into delays.
What about restrictions on who can operate the fueling equipment? Absolutely. Most jurisdictions require that anyone refueling large LPG tanks (over 1,000 liters, usually) be trained and certified in LPG safety. For small passenger vehicle refueling, some places allow self-service, but many require that an attendant be present to help with the process. We’ve seen stations that tried to skip training to save money, and it almost always leads to mistakes—last year, a small truck stop we consulted for had a customer try to refuel a cylinder while it was still hot from being used on a grill, which caused a pressure release. Proper training for both staff and customers is a restriction that’s often overlooked, but it’s one of the most important for preventing incidents. Our team offers free safety training sessions for every operator who buys our equipment, so they can make sure their staff is up to date on all current rules.
There are also restrictions on storing LPG on-site that tie directly to fueling operations. You can’t store more LPG than your license allows, and storage tanks have to be installed at a safe distance from fueling points and other structures. Stations have to keep storage areas well-ventilated, with no vegetation or debris that could catch fire nearby. We design our storage tank systems with secondary containment—basically, a barrier around the tank that can catch any leaks, so they don’t spread into the fueling area. We also install pressure relief valves that release excess gas safely if the tank gets too hot, which complies with all storage restrictions.
Another common restriction is around refueling during severe weather. Thunderstorms, for example, are a no-go at most LPG stations because of the risk of lightning strikes. Even if a station has lightning protection (which all our equipment includes), the National Fire Protection Association (NFPA) and similar bodies advise pausing refueling when lightning is in the area. We install weather alerts that automatically remind operators to stop fueling when severe weather is detected, which is a simple but effective way to follow this rule. We’ve also had stations that tried to stay open during storms to avoid losing customers, and while it can be a hit to revenue, the risk of a lightning igniting LPG vapor is just not worth it.
Wait, there’s a restriction I haven’t heard mentioned much before—around refueling passenger vehicles with small LPG tanks. Some places have rules that limit public LPG stations to serving commercial vehicles and larger residential appliances, not regular passenger cars. That’s usually because of the risk of overfilling or improper connections on smaller tanks. Our pumps are adjustable, so we can set them to only dispense the volume that’s safe for small passenger tanks, which helps operators comply with those restrictions. We also work with stations to clearly mark which pumps are for which use case, so customers don’t accidentally use a pump that’s restricted for larger vehicles.
Now, I want to be clear: these restrictions aren’t meant to make running an LPG station harder. They’re put in place because LPG is a safe, efficient fuel, but it’s a pressurized gas that needs to be handled with respect. As a supplier, our job isn’t just to sell pumps and tanks—it’s to design equipment that works within these restrictions, provides clear guidance to operators, and helps keep everyone safe. I’ve had operators tell me that they were overwhelmed by the number of rules when they first started, but after working with our team, they feel confident that they’re following every regulation without missing a detail.
I also want to address a common misconception: some people think restrictions change all the time, but the core principles have stayed consistent over the years. What does change is regional specifics, which is why we tailor our solutions to each location we work in. For example, a station in Germany might have different distance requirements than one in Canada, but the safety logic behind the rules is the same. We stay up to date on all national and local safety codes, so our operators don’t have to—we handle the research and adjust our equipment accordingly.
If you’re a station owner looking to set up a new LPG facility, or an existing operator looking to upgrade your equipment to stay compliant, the key is to work with a supplier who understands these restrictions inside and out. We don’t just show up with a pump and leave; we walk you through every rule, how our equipment helps you follow it, and provide ongoing support to make sure you stay compliant as regulations evolve.
If you’re ready to discuss setting up a new LPG fueling station or upgrading your current equipment, we’d be happy to connect you to our team for a no-obligation consultation. We’ll review your site, walk you through all applicable restrictions, and provide a customized solution that meets your needs while keeping safety top of mind.
