Smoking near gas pumps
Although the chances of a cigarette igniting gasoline vapors may seem slim, the potential consequences of an explosion or fire are severe. The concentration of fumes under a canopy, for example, can significantly increase the risk of combustion. Additionally, fuel vapors tend to linger near the ground, and in extreme cases of significant vapor leakage over several hours, a cigarette or a motorbike backfire could trigger an explosive combustion. While the resulting explosion may be brief and relatively small, the presence of larger fuel sources or direct access to a fuel tank could lead to a much larger disaster.
To ensure safety, it is recommended to maintain a significant distance between smoking areas and gas pumps. Some sources suggest a distance of 20 feet or more from the gas pump or dispenser. Additionally, designated smoking areas should be located in open spaces, away from any structures that could concentrate fumes. It is also important to follow other safety guidelines at gas stations, such as turning off engines and refraining from using cellular devices during refueling, to minimize the risk of ignition.
While diesel fuel may be less susceptible to ignition than gasoline, it is still highly flammable and can pose a significant risk when exposed to an ignition source. Therefore, it is crucial to maintain the same safety precautions when smoking near diesel fuel as with gasoline. The distance requirements and safety measures apply equally to both types of fuel to prevent potential fires or explosions.
Overall, smoking near gas pumps, whether diesel or gasoline, is extremely unsafe and should be strictly avoided. The invisible gasoline vapors and the potential for fuel leaks create a highly flammable environment. By maintaining a safe distance, utilizing designated smoking areas in open spaces, and adhering to other safety guidelines, individuals can significantly reduce the risk of a catastrophic incident.

Diesel vs. gas fumes
While smoking near a gas station is unsafe, there is no universally accepted law that prohibits it. However, some individuals suggest maintaining a distance of at least 20 feet from a gas pump while smoking. According to another source, the NFPA recommends staying 25 feet away from the dispenser.
When it comes to diesel vs. gas fumes, there are differing opinions on which is more harmful. Several sources claim that diesel fumes are significantly more damaging to health than petrol or gasoline fumes. Diesel exhaust fumes have been linked to asthma, lung disease, heart attacks, and other respiratory issues. In 2013, the UN's World Health Organization declared that diesel exhaust could cause cancer and had effects comparable to secondary cigarette smoking. Additionally, diesel engines produce more particulates and NOx, which can be harmful with chronic exposure.
On the other hand, some argue that gasoline or petrol fumes are more dangerous. Petrol engines produce higher levels of carbon monoxide, a highly toxic gas. As a result, running petrol engines indoors is much riskier than diesel engines. Gasoline vehicles also contribute more to a specific type of air pollution, secondary organic aerosols (SOA), than diesel vehicles. A study in Los Angeles found that gasoline was responsible for 80% or more of the SOA particles, while diesel's contribution was negligible at 20% or less.
It is worth noting that fuel compositions and technologies are constantly evolving, making direct comparisons between diesel and gasoline emissions challenging. Additionally, factors such as vehicle type and size can also influence the emissions output.

Ignition sources
While diesel fuel presents a lower risk of ignition than gasoline, it is still unsafe to smoke near diesel fuel. The primary concern is not the diesel fuel itself, but rather the fumes that it emits, which can be ignited by a lit cigarette or other ignition sources.
It is important to understand the potential ignition sources that could be present when smoking near diesel fuel. While a lit cigarette or lighter may seem like the most obvious source, there are other factors to consider as well.
One potential source of ignition is static electricity. While rare, it is possible for static electricity to ignite diesel fumes, particularly in refined fuel. This risk is higher in enclosed or concentrated areas, such as under a canopy, where fumes can accumulate and create a more hazardous environment.
Additionally, cellular devices have been known to cause fires in certain cases, although this is not a common occurrence. However, it is always advisable to put your phone away and focus on the task at hand when handling flammable liquids, such as diesel fuel.
Another potential ignition source is sparks or open flames. While diesel engines themselves do not typically use spark plugs for ignition, other equipment or sources nearby could potentially create sparks or open flames that could ignite diesel fumes.
Furthermore, environmental factors such as humidity can play a role in the ignition risk. On a humid day, diesel fumes can collect and become more concentrated, increasing the risk of ignition.
It is worth noting that while diesel fuel may have a lower risk of ignition compared to gasoline, it is still flammable and can combust under certain conditions. Therefore, it is crucial to maintain a safe distance and take the necessary precautions to prevent any potential hazards.

Fire safety codes
While I could not find specific information on how many feet away from diesel fuel one can smoke, I did find a range of fire safety codes and guidelines that apply to the storage and handling of flammable liquids and combustible materials. These guidelines are intended to minimize the risk of fire and ensure the safety of people and property.
- Smoking is strictly prohibited in areas where flammable liquids are stored, handled, or dispensed. This includes fueling operations and servicing fuel systems for internal combustion engines.
- "No Smoking or Open Flame" signs must be posted conspicuously in these areas to deter people from engaging in activities that could potentially cause a fire.
- Dispensing units for flammable liquids must be located at least 20 feet (6.08 meters) away from any fixed sources of ignition. This distance is maintained to prevent accidental fires during fueling operations.
- Portable fire extinguishers must be readily available and easily accessible in the yard area. The maximum travel distance to the nearest fire extinguisher should not exceed 100 feet.
- When storing flammable liquids, there should be a minimum separation of 20 feet (6.08 meters) between a liquefied petroleum gas container and a flammable liquid storage tank. This distance is crucial to prevent the spread of fire in the event of an accident.
- Temporary buildings or structures that are not used for storing or handling flammable liquids or hazardous materials should be located at least 10 feet away from another building or structure.
- Internal combustion engine-powered equipment should be positioned in a way that keeps their exhausts well away from combustible materials. A clearance of at least 6 inches is required between the piping and combustible materials.
- Heaters used near combustible tarpaulins, canvas, or similar coverings must maintain a distance of at least 10 feet from the coverings. These coverings should be securely fastened to prevent ignition from wind action.
- Asphalt (tar) kettles should not be located within 20 feet (6.08 meters) of any combustible material, building surface, or opening. They should be operated in controlled areas identified by traffic cones or barriers.
- In California, fire safety codes require maintaining a firebreak zone around buildings or structures by removing flammable vegetation located within 30 to 100 feet of these structures. This helps create a buffer zone to enhance fire safety and protect buildings from potential wildfires.
These fire safety codes provide guidelines for handling flammable liquids, combustible materials, and smoking restrictions. They are designed to prevent fires, ensure safe operations, and protect people, property, and the environment from potential fire hazards.
