Gas Station Fire Protection Equipment Requirements: Extinguishers, Fire Sand and Emergency Safety
News 2026年 8月 21日 74
Gas stations store and dispense flammable fuels, making fire protection an essential part of station design and daily operation.
A complete fire protection strategy should not rely on a single piece of equipment. It should combine portable fire extinguishers, fire blankets, fire sand, emergency shut-off systems, appropriate fire water systems where required, warning signs and regular inspection.
For projects in China, GB 50156-2021 provides specific requirements for fire-fighting equipment at filling stations. International projects may instead be governed by local fire codes and standards such as NFPA 30A, so equipment quantities and performance requirements should always be confirmed with the local authority having jurisdiction (AHJ).
1. Why Is Fire Protection Important at a Gas Station?
A gas station contains several areas where flammable fuel or vapor may be present, including:
- Fuel dispensers
- Underground fuel tanks
- Tank filling points
- Fuel unloading areas
- Vapor recovery systems
- Fuel pipelines
- Electrical equipment
A fire can develop rapidly if fuel, vapor and an ignition source are present at the same time.
The basic fire safety principle is:
Prevent ignition → Detect the problem → Stop fuel flow → Control the initial fire → Evacuate if necessary
This is why fire protection equipment should be integrated with the station’s emergency shut-off, fuel unloading, vapor recovery and electrical safety systems.
2. Fire Extinguishers at Fuel Dispensers
Portable fire extinguishers are one of the most important first-response devices at a gas station.
Under GB 50156-2021, for every two fuel dispensers, a station should provide at least:
- Two 5 kg portable dry powder fire extinguishers, or
- One 5 kg portable dry powder extinguisher and one 6 L foam extinguisher
If fewer than two fuel dispensers are installed, the requirement is still calculated based on two dispensers.
This means that fire extinguishers should be positioned so that operators can reach them quickly without entering an area affected by fire or fuel leakage.
For international projects, the required extinguisher type, rating and travel distance may differ.
For example, NFPA 30A-2024 requires portable fire extinguishers for outdoor liquid motor-fuel dispensing areas and limits the travel distance to a single extinguisher to 23 m (75 ft) for each fuel dispensing island or group of islands.
Therefore, the correct approach is:
Use the local fire code to determine the final extinguisher type, rating, quantity and location.
3. Fire Extinguishers for Underground Fuel Tanks
Underground fuel tanks are another important part of the fire protection system.
GB 50156-2021 specifies that an underground storage tank should be provided with:
One portable dry powder fire extinguisher of at least 35 kg
If different types of storage tanks are separated by more than 15 m, they should be provided separately according to the standard’s requirements.
The purpose of a larger wheeled extinguisher is to provide greater firefighting capacity in areas associated with fuel storage and transfer.
4. Fire Blankets and Fire Sand
Fire protection at a gas station is not limited to extinguishers.
GB 50156-2021 also specifies fire blankets and sand for different grades of filling stations.
For Grade I and Grade II filling stations, the standard requires:
- 5 fire blankets
- 2 m³ of sand
For Grade III filling stations:
- At least 2 fire blankets
- 2 m³ of sand
Combined filling and gas stations should follow the corresponding requirements for the filling-station grade.
What is fire sand used for?
Fire sand can be used as an auxiliary measure for controlling small fuel spills and limiting the spread of spilled flammable liquid.
It should not be considered a replacement for a suitable fire extinguisher.
A simple distinction is:
Fire Extinguisher → Suppress an initial fire
Fire Sand → Help control a small fuel spill
Fire Blanket → Smother certain small fires where appropriate
5. Fire Protection During Fuel Unloading
Fuel unloading is one of the most important operations at a gas station.
Fire protection should therefore be coordinated with the overall fuel unloading system.
A typical process is:
Tanker Truck
↓
Unloading Connection
↓
Underground Fuel Tank
↓
Fuel Storage
During unloading, several risks need to be controlled:
- Fuel leakage
- Flammable vapor
- Static electricity
- Ignition sources
- Hose or connection failure
- Incorrect valve operation
Therefore, the unloading area should have appropriate fire protection equipment that is easily accessible.
The fire protection system should also work together with:
- Static grounding
- Vapor recovery
- Emergency shut-off
- Spill control
This is why fire safety should not be designed separately from the fuel unloading system.
6. Emergency Shut-Off and Fire Protection
A fire protection system should also be able to stop the continued supply of fuel.
If a fire or serious emergency occurs, continuing to pump fuel can increase the amount of fuel available to the fire.
An emergency shut-off system can be used to stop fuel transfer and reduce the potential escalation of the incident.
A simplified emergency response sequence is:
Fire Detected
↓
Activate Emergency Shut-Off
↓
Stop Fuel Transfer
↓
Use Appropriate Fire Extinguisher
↓
Evacuate Personnel
↓
Notify Emergency Services
This is why the emergency shut-off system should be installed in an accessible location and clearly identified.

7. Fire Protection Around Fuel Dispensers
The fuel dispenser area should be designed so that fire-fighting equipment is accessible without obstructing normal fueling operations.
Important considerations include:
- Fire extinguisher accessibility
- Emergency shut-off accessibility
- Clear evacuation paths
- No obstruction around fire equipment
- Appropriate warning signs
- Control of ignition sources
NFPA 30A-2024, for example, requires warning signs in dispensing areas and prohibits smoking or ignition sources within specified distances. It also requires portable fire extinguishers to be selected, installed, inspected and maintained according to the applicable fire-extinguisher standard.
This shows that fire protection is not simply about how many extinguishers are installed.
Their location, accessibility, inspection and maintenance are equally important.
8. Fire Water Systems
Not every gasoline station requires the same type of fixed fire-water system.
The requirement depends on:
- Station type
- Fuel type
- Storage capacity
- Site layout
- Local fire code
- Risk classification
- Authority requirements
Under GB 50156-2021, specific fire-water requirements apply to certain facilities such as LPG and hydrogen-related installations. Therefore, fixed fire-water systems should not automatically be presented as a universal requirement for every gasoline-only station.
For projects outside China, the final design should be checked against the applicable local fire code.
9. Fire Protection for Electrical Equipment
Gas stations also contain electrical and electronic equipment such as:
- Distribution panels
- Control cabinets
- Fuel dispenser electronics
- Tank monitoring systems
- Communication equipment
- Lighting systems
Electrical faults can become an ignition source in inappropriate environments.
Therefore, fire safety should be coordinated with:
- Electrical protection
- Grounding
- Lightning protection
- Explosion-hazardous area classification
- Emergency shut-off systems
This is particularly important in modern stations where electronic control and monitoring systems are increasingly integrated into fuel operations.
10. Fire Protection Equipment Inspection
Installing fire-fighting equipment is only the first step.
A gas station should establish a regular inspection and maintenance program.
A basic inspection checklist can include:
| Equipment | Inspection Focus |
|---|
| Portable fire extinguishers | Pressure, condition, accessibility |
| Wheeled dry powder extinguishers | Pressure, hose, wheels and accessibility |
| Fire blankets | Condition and accessibility |
| Fire sand | Quantity, dryness and accessibility |
| Fire hydrants | Availability and condition where installed |
| Emergency shut-off | Function and accessibility |
| Fire alarm | Alarm and power status where installed |
| Warning signs | Visibility and condition |
The inspection interval and testing method should follow the applicable local regulations and equipment manufacturer’s requirements.

11. Common Gas Station Fire Protection Problems
Problem 1: Fire extinguishers are installed but difficult to access
An extinguisher hidden behind equipment is not an effective emergency response device.
Solution: Keep fire-fighting equipment clearly visible and accessible.
Problem 2: Fire equipment is not inspected regularly
A fire extinguisher may look normal from the outside but still require inspection or maintenance.
Solution: Establish a documented inspection and maintenance program.
Problem 3: Fire protection and emergency shut-off are designed separately
Stopping fuel flow is an important part of controlling a fuel-related fire.
Solution: Coordinate the fire protection system with the emergency shut-off system.
Problem 4: Fire sand is treated as a substitute for an extinguisher
Fire sand has a different purpose from a portable fire extinguisher.
Solution: Provide both according to the applicable project requirements.
Problem 5: One country’s fire protection requirements are applied directly to another country
This can create compliance problems during project approval.
Solution: Use the applicable local fire code and confirm requirements with the local AHJ.
12. Gas Station Fire Protection Checklist
Before commissioning a gas station, consider checking:
| Item | Key Question |
|---|
| Fire extinguishers | Are the correct type and quantity provided? |
| Fire extinguisher location | Can personnel reach them quickly? |
| Fire blankets | Are they provided where required? |
| Fire sand | Is the required quantity available? |
| Fuel unloading | Is appropriate fire protection available? |
| Emergency shut-off | Can fuel flow be stopped quickly? |
| Warning signs | Are required signs visible? |
| Electrical equipment | Are electrical/fire risks properly controlled? |
| Fire water | Is a fixed system required by the local code? |
| Inspection | Is a regular inspection program established? |
13. Final Takeaway
A reliable gas station fire protection system should not depend on one piece of equipment.
It should combine:
Fire Extinguishers
For controlling initial fires.
Fire Blankets
For specific small-fire situations where appropriate.
Fire Sand
For auxiliary fuel-spill and fire control.
Emergency Shut-Off
For stopping fuel transfer during an emergency.
Fire Water Systems
Where required by the applicable fire code and project conditions.
Inspection and Maintenance
To ensure that fire protection equipment remains ready for use.
For projects designed according to GB 50156-2021, some useful reference values include two 5 kg dry powder extinguishers for every two fuel dispensers, one 35 kg or larger wheeled dry powder extinguisher for underground storage tanks, and specified quantities of fire blankets and sand according to station grade.
However, these figures should not be treated as universal international requirements. For projects in other countries, the final fire protection design should comply with the local fire code and approval requirements.
