Unlike any other type of fuel, gasoline transfer is quite risky due to the volatility of gasoline vapors at room temperature. For the safe transfer of gasoline, you will need an adequate gasoline transfer pump, proper bonding and grounding, a fuel hose, ventilation, and control of the ignition source. Approved containers and a spill plan are also necessary. The Aocheng Group manufactures fuel transfer systems, but you should determine which pump is adequate for your case.
First of all, the flash point of gasoline is much lower than that of diesel. Even though diesel is heated up to a very high temperature to burn, gasoline may generate ignitable vapor at normal outside temperatures. This means that gasoline can catch fire because of a spark, static electricity, hot surface, and flame just by their presence near gasoline without contact with it.
Vapor generated by gasoline is heavier than air. This means that the vapor may accumulate in the low areas and move towards the place with an ignition source without contacting it. It is especially dangerous when it comes to enclosed spaces such as pits, drains, and poorly ventilated workplaces.
Even though diesel is a flammable fuel too, using gasoline requires a specific approach to vapor handling and ignition sources. It is the reason why every gasoline transfer system should be considered a potential fire source regardless of its design.
Both bonding and grounding will decrease the possibility that static electricity will become an ignition source. Bonding guarantees that all equipment and containers that you use have the same electrical potential. Grounding provides a way for the electrical charges to go through the earth.
Before you begin to unseal the containers, follow the process outlined by the manufacturer of the equipment as well as the site to bond the source container, pump, hose or nozzle, and receiving container if necessary. Use the verified grounding point and make sure that the connections are secure. It is not sufficient to have a metal container on the ground.
All fuel pumps may not be suitable for the use of gasoline. The fuel pump that is designed to handle diesel, water, and lubricating oil may not have the right seals, materials, electrical components, and ignition protection.
Use an approved gasoline pump that is listed and has proof that the pump is designed for gasoline or flammable liquid. All electrical equipment used in a classified hazardous area should be listed and should meet the required rating for the area.
The selection of a gasoline transfer pump should be done based on the fuel and the requirements, not flow and cost.
The hose must be made to work with gasoline and should have appropriate static properties. Conductive lining or a static conductor may be necessary depending upon the hose and the system being used.
Each time you use it, check the hose for cuts, cracks, swellings, loose connections, or other damage. Check the hose for proper grounding and bonding per the manufacturer’s instructions. The hose cannot be repaired in any way and needs to be discarded whenever it is damaged.
The hose and fittings are a vital part of the safety system. An appropriately rated pump will not be able to replace proper hose and fittings.
Static electricity fuel risks may arise while transferring gasoline using a hose or when filling the receiving tank. Any fuel splash or movement will increase static electricity, and this might act as a source of ignition if there are any vapors.
The nozzle should always be kept in contact with or close to the bottom of the receiving tank. The transferring process should be done at a steady rate and should not be stopped unnecessarily.
The correct type of conductive hose and receiving tank must be used. It is not advisable to use a plastic funnel or an ungrounded plastic tank instead.
The process of transferring the gasoline will be done outdoors or in a well-ventilated place. The following places, including drains, pits, holes in buildings, running engines, electrical equipment, smoking zones, and any source of fire, will not be near the place where the process will be performed.
The process of pumping should not be done in a place without adequate ventilation. This is because the vapor of the gasoline can accumulate to the point of causing a fire despite the equipment being away from the source of the vapor.
Ventilation doesn’t eliminate the need for ignition control and the right equipment rating.
It is possible for the fuel to continue flowing despite the pump not working due to the siphoning risk. An unconnected hose may lead to fuel spillage, disconnections, or even fuel being transferred to unintended areas.
Integrate the anti-siphon or check valve system into the design of the pump. Close the valves after completing the process of fuel transfer and secure the ends of the hoses if they are not in use. Always be near the fuel transfer process.
Before you begin, make sure you know how to stop the fuel flow in case of any leaks or malfunctions.
Gasoline is to be transferred into those containers or tanks which are approved for carrying this fuel type. Containers should not be filled to the top but should be kept on a level surface with proper expansion space left.
Follow the applicable procedure for filling containers in or on vehicles. Where bonding and grounding are required, complete those steps before transferring fuel. Do not assume that a container is suitable simply because it can hold liquid without leaking.
A safety can should be designed for flammable-liquid storage and used according to its instructions. Ordinary household bottles and unsuitable plastic containers are not substitutes.
All safety measures must be taken before the pump is turned on. Ensure that all the materials for cleaning spills and the correct fire extinguisher are available based on the site’s protocol. The gloves and goggles must be worn while performing the task.
Know how to turn off the pump, block any fuel sources from leaking out, and stop the fuel flow. In case there is any spill of gasoline, try to stop the flow if possible, avoid the area, and clean the spillage based on the site’s protocol. Never turn on any electrical switch or use any equipment that can be an ignition source in such environments.
In case gasoline touches your skin, rinse the affected area and change the clothes that may be contaminated. In case you inhale the fumes, move to fresh air.

Explore Product & SolutionsThis depends on the type of pump, its usage, and where it is supposed to be operated. The buyer should insist on the certification for the entire pump system and not the motor alone.
| Certification or marking | What to check |
| UL or ETL listing | Confirm that the listing covers the pump’s intended fuel-transfer use. UL 79 addresses flammable-liquid dispensing equipment, but the applicable standard depends on the product type. |
| Class I, Division 1 or 2, Group D | For relevant electrical equipment in US hazardous locations, verify that the classification matches the installation. |
| ATEX or IECEx | For applicable international hazardous-area installations, check the exact equipment category, zone, protection method, and certificate scope. |
| CE or UKCA marking | Check the applicable conformity documents. These marks alone do not establish that a pump is suitable for gasoline in a hazardous location. |
| Grounding point and static-control features | Confirm that the design supports the bonding, grounding, and hose requirements of the transfer setup. |
The requirements for certification depend on the specific application and jurisdiction. Just because there is certification for an electric motor doesn’t mean the whole pump assembly is appropriate for gas. Each component in the pump needs to be suitable for its environment.
The cause of many transfer fires may be attributed to neglecting the basics or thinking that equipment approved for one fuel will also be suitable for another. Among the possible mistakes are using a diesel-only or unapproved pump, failure to bond the fuel source and the receiving containers, as well as using a damaged hose.
Additional factors that may contribute to the problem are pumping in a place with poor ventilation, splashing of gasoline while transferring it to a container, leaving the equipment unattended, and failing to interrupt the flow when the pump is switched off. In addition, smoking or having a source of ignition near the transfer point is dangerous. Another mistake may be taking the word of the manufacturer about their products without checking the certifications. The term “explosion-proof” should be certified according to the hazardous-area classification. Moreover, the approved gasoline pump should be used together with proper containers and hoses.
