Diesel fuel is classified as a dangerous good for storage but not for transport
Diesel fuel is a type of fuel derived from crude oil. It is used in most large engines, including those in trucks, buses, trains, and ships. It is also used in construction, farm, and mining equipment, as well as generators, and some cars. Diesel fuel is often used to power military vehicles and machinery in deployment settings because it is more efficient and less flammable than other types of fuel.
Despite being less flammable, diesel fuel can still be dangerous. It can be absorbed through the skin, inhaled, or accidentally swallowed. Exposure to diesel fuel and exhaust can lead to a variety of health issues depending on the length and frequency of exposure, the amount of exposure, age, sex, genetic traits, and diet. Short-term exposure to diesel exhaust can cause nausea, eye irritation, increased blood pressure, headaches, lightheadedness, loss of appetite, coughing, throat irritation, and respiratory tract irritation. Skin contact with diesel fuel can also cause skin irritation.
Long-term exposure to diesel exhaust has been linked to more serious health issues, including lung cancer and bladder cancer, and effects on the immune, respiratory, urinary, and cardiovascular systems, such as asthma and kidney damage. The International Agency for Research on Cancer (IARC), which is part of the World Health Organization (WHO), has classified diesel engine exhaust as carcinogenic to humans, specifically increasing the risk for lung cancer.
Due to the dangers of diesel fuel, there are specific guidelines for its storage and transport. Interestingly, diesel fuel is classified differently for storage and transport. For transport purposes, diesel fuel is not classified as a dangerous good by the ADG code. This is because diesel fuel typically has a flashpoint above 60 degrees Celsius and thus does not meet the specifications of flammable liquids outlined by the Australian Standard AS1940-2017. However, for storage purposes, diesel fuel is classified as a dangerous good and must comply with the Australian Standard AS1940-2017, which outlines the safe storage requirements for flammable and combustible liquids. This standard includes specifications such as the use of indoor storage cabinets with specific design features, safety signage, and spill containment sumps.

Exposure to diesel exhaust can cause short-term health issues
Diesel fuel is commonly used in military operations, powering vehicles and machinery such as tanks, trucks, and generators. It is also used in civilian settings, powering engines in trucks, buses, trains, ships, and cars. While diesel fuel is not classified as a dangerous good for transport under certain regulations, it is considered a dangerous good for storage due to its combustible nature.
Exposure to diesel exhaust, a mixture of gases and particulates produced during diesel fuel combustion, can have adverse health effects. Short-term exposure to diesel exhaust can lead to coughing and irritation of the eyes, nose, throat, and respiratory tract. The eyes and nose may be irritated, and symptoms such as headaches, nausea, and increased blood pressure may occur. Skin contact with diesel fuel can also cause skin irritation.
The health effects of diesel exhaust exposure depend on factors such as duration and frequency of exposure, age, sex, genetic traits, and diet. To minimize exposure, individuals can avoid spending time near large sources of diesel exhaust, such as trucks and buses. Workplace precautions, such as using personal protective equipment and implementing exhaust treatment systems, can also help reduce exposure risks.
While the focus here is on the short-term health effects of diesel exhaust exposure, it is important to recognize that long-term, heavy exposure may lead to more serious health issues, including lung cancer.

Long-term exposure to diesel exhaust can cause lung and bladder cancer
Diesel fuel is commonly used in military operations and to power large engines in vehicles such as trucks, buses, trains, and ships. It is also used in construction, farming, mining equipment, and generators. While diesel fuel is not classified as a dangerous good for transportation purposes, it is classified as a dangerous good for storage. This is due to its combustible nature, which requires specific safety measures to be implemented during storage and handling.
The health effects of diesel fuel exposure depend on various factors, including the duration and frequency of exposure, the amount of exposure, age, sex, genetic traits, and diet. Short-term exposure to diesel exhaust can cause coughing, nausea, eye irritation, increased blood pressure, headaches, lightheadedness, and respiratory tract irritation.
Long-term exposure to diesel exhaust, however, is a more serious concern. Several studies have linked long-term, heavy exposure to diesel exhaust with an increased risk of lung cancer in humans and lab animals such as rats. The International Agency for Research on Cancer (IARC), a part of the World Health Organization (WHO), has classified diesel engine exhaust as carcinogenic to humans (Group 1). This classification is based on evidence that exposure to diesel exhaust emissions increases the risk of lung cancer and possibly bladder cancer.
The carcinogenic effects of diesel exhaust are attributed to its composition. Diesel exhaust is a complex mixture of gases and soot (particles). The gas portion includes carbon dioxide, carbon monoxide, nitric oxide, nitrogen dioxide, sulfur oxides, and hydrocarbons, including polycyclic aromatic hydrocarbons (PAHs). PAHs have been shown to cause cancer in animal studies. The soot portion of diesel exhaust consists of particles such as carbon, organic materials (including PAHs), and traces of metallic compounds. These fine and ultra-fine particles can penetrate deeply into the lungs, evading the body's natural defense mechanisms.
To mitigate the risks associated with diesel exhaust exposure, various control measures can be implemented. These include replacing diesel-powered engines with alternative power sources, using alternate fuels or cleaner energy sources, employing low-emission engines or fuel additives, utilizing exhaust treatment systems, and ensuring proper ventilation in workplaces and indoor spaces. Additionally, individuals can limit their exposure by reducing the time spent near idling engines and large sources of diesel exhaust, such as trucks and buses.

Diesel exhaust is a mixture of gases and soot particles
The exact nature of the exhaust depends on several factors, including the type of engine, its maintenance, the type of fuel and oil used, the engine's speed, and load, and the presence of emission control systems. The particulate matter emitted by diesel engines is known as diesel particulate matter (DPM) and primarily consists of solid elemental carbon (EC) cores with organic carbon (OC) compounds adhered to their surfaces.
DPM is a concern for human health as it is respirable, meaning the particles can enter the lungs deeply, bypassing the body's natural defence mechanisms. Short-term exposure to diesel exhaust can cause coughing and irritation of the eyes, nose, throat, and respiratory tract. It can also lead to lung irritation and allergic reactions, causing asthma and breathing difficulties.
Long-term exposure to diesel exhaust has been linked to more severe health issues. Studies have found that long-term, heavy exposure can cause lung cancer in lab animals, and the International Agency for Research on Cancer (IARC) has classified diesel engine exhaust as carcinogenic to humans, increasing the risk of lung cancer and possibly bladder cancer. Other possible long-term health effects include impacts on the immune, respiratory, urinary, and cardiovascular systems, such as asthma and kidney damage.

How to limit exposure to diesel exhaust in the workplace
Diesel exhaust is a mixture of gases and particulates produced during the combustion of diesel fuel. Exposure to diesel exhaust in the workplace can have adverse health effects on workers, ranging from eye and nose irritation to headaches, nausea, respiratory disease, and lung cancer. Here are some ways to limit exposure to diesel exhaust in the workplace:
Ventilation and Exhaust Systems
Appropriate ventilation systems can help reduce exposure to diesel exhaust. Positive pressure ventilation, exhaust extraction devices, inlet and exhaust general (dilution) ventilation, and local exhaust systems such as tailpipe hose exhaust can be implemented. Ensure that exhaust hoses are placed to vent emissions outdoors, preventing them from re-entering the workplace. Modify the layout of the work area to separate areas where people work from exhaust generation zones. For example, isolate generators in separate, ventilated spaces or place workers in sealed, air-conditioned cabins with filtered air. Keep openings for booths small and closed as much as possible when there is a risk of exhaust exposure, and provide adequate ventilation with fresh air when necessary.
Control Measures
Implement control measures to reduce diesel exhaust emissions. Replace diesel-powered engines with electric or alternative power sources, or use alternate fuels like propane, natural gas, or low-sulfur diesel. Utilize low-emission engines, fuel additives, and exhaust treatment systems such as filters, catalysts, and converters, along with corresponding maintenance programs. Ensure that engines are maintained to prevent exhaust leaks into cabs or passenger areas.
Training and Education
Provide workers with instruction and training on the health hazards associated with diesel exhaust exposure and the proper use of control measures. Educate workers on the signs of exposure, such as the ability to see or smell diesel exhaust, and the importance of addressing the issue promptly.
Risk Assessments and Hazard Investigations
Conduct risk assessments and hazard investigations to determine the health risks associated with diesel exhaust exposure and identify necessary control measures. Regularly monitor exposure levels and compare them with occupational exposure limit values. Indicators such as respirable particles, elemental carbon, and nitrogen oxides can be measured to assess exposure levels.
Personal Protective Equipment
Provide respiratory protection devices for employees who may be exposed to diesel exhaust. Ensure that personal protective equipment is properly fitted and maintained to minimize exposure risks.
By implementing these measures, employers can help protect workers from the harmful effects of diesel exhaust exposure and create a safer work environment.
