As we all know diesel fuel has a high flammability rate, thus, safety during refueling operations is crucial to prevent worker injuries and environmental damage. Take the example of a refueling incident in March 2024. About 100 gallons of green-dyed diesel spilled into Norfolk’s Elizabeth River during NOAA ship refueling. While quickly contained, it raised concerns about environmental impact and fuel safety.
The introduction of technological advancements like fast-fill systems has significantly boosted refueling efficiency. But it has also brought 3 fuel tank hazards: tank pressurization, diesel spills, and baths. That’s why we’ve compiled this Diesel Refueling Safety Bulletin. In this, we’ll talk about the typical refueling risks and the variables that contribute to them. We’ll also help you prevent diesel spills and other issues by sharing effective diesel refueling safety practices.
Common Hazards in Diesel Refueling
Refueling with diesel may sound simple but this comes with certain risks that can cause safety and environmental problems. Here are some common diesel hazards you may face while refueling:
Pressurizing Fuel Tanks
Fast-fill systems can overpressurize fuel tanks, exceeding their limits (13-14 PSI) and causing structural stress. Over time, this pressure can deform or weaken tanks, leading to ruptures within a few years. Such failures can increase the risk of spills and leaks, compromising safety and storage integrity.
Increased Spill Volumes
“Topping off” a tank after the automatic shut-off can cause large spills, especially if the shut-off is overridden. A spillage rate exceeding 10 liters per second will result in burdensome cleanup expenses and monetary penalties. The spilled fuel also poses two main environmental hazards. It can contaminate land surfaces and aquatic environments.
Refueling operations can also expose companies to legal problems. These issues develop when environmental laws such as the Clean Water Act and the Oil Pollution Act are not followed correctly. These laws restrict any oil pollutant discharge into water systems unless authorities grant permission.
Diesel Baths
When refueling, diesel baths manifest as fuel leakages through vents thereby exposing workers to dangerous fumes and liquids. Besides, long-time exposure to diesel baths can result in eye injuries, skin irritation, and many other health problems that may need medical care.
Spillages During Operation
The process of overfilling tanks, when equipment runs, creates a high risk of spills occurring. The uncontrolled fuel spillage during mishandling exposes crews to severe dangers that may initiate hazardous fires, harm the environment, and result in substantial expenses.
Factors Contributing to Diesel Refueling Risks
Understanding the elements that increase risks during diesel refueling operations can enable you to develop protective strategies that stop accidents. Here are some variables:
Uneven Terrain
Refueling diesel on uneven terrain can be dangerous, especially for mobile equipment. Rough ground increases the risk of tipping, which can cause spills and put workers at risk.
Besides, unstable surfaces also make it harder to control fueling, leading to overfills that contaminate the area and create fire hazards. Thus maintaining safety procedures becomes much more difficult, increasing the chances of incidents. Spills can also lead to costly cleanups and project delays.
Limited Operator Training
Inadequate training of workers creates unsafe conditions that put them at risk during the refueling process. Some risks like not knowing how to avoid static buildup and handle spills become dangerous because operators do not have proper knowledge about these prevention steps. Thus, regular training of operators is crucial for safety and risk prevention.
Outdated Industry Standards
Outdated refueling standards can compromise safety and harm the environment, As technology improves, older protocols may not address new risks or use advanced safety measures.
Many current standards also lack modern spill-prevention tools. Thus increasing the chances of accidents. Without updates, spills can contaminate soil and water, damaging ecosystems. Staying compliant with evolving regulations is also crucial to avoid fines and legal issues.
Inadequate Knowledge
Public ignorance about tank pressurization hazards produces serious accidents in the workplace. Operators without proper understanding can perform fueling operations in the wrong way because of which tank damage, spills, and explosions are more likely. Visible safety necessitates training as a required step for protection.
Underreporting or Minor Spills
Not reporting small fuel spills can cause serious environmental and legal problems. Operators may avoid reporting due to fear of penalties, creating secrecy and a false sense of safety. Over time, these minor spills add up, harming water quality and ecosystems.
Ignoring them can also hide operational issues, increasing the risk of a major spill. Not to mention, legally failing to report spills can lead to fines and penalties from regulatory agencies. Therefore, transparency is key to maintaining public trust as companies that openly handle spills are viewed more positively.
Recommendations For Safer Diesel Refueling
You’ll need to safeguard both personnel and environmental assets from contamination as well as spills and fires during the refueling process. The following guidelines can help make diesel fuel refueling practices safer:
Training and Awareness
Train operators thoroughly in safe refueling practices, including proper diesel handling, emergency response, and safety protocols. The primary reason for safety risks stems from employees lacking knowledge about diesel fuel specifications and diesel fuel hazardous area classification. So, teach them about it. Diesel specifications state that the flashpoint of conventional diesel extends from 126°F to 204°F, making it combustible.
While diesel fuel storage tanks do not fit the category of hazardous area classification, assessments are needed if fuel is heated unnaturally or its flashpoint drops below 60°C. Safe practices, including explosion-proof equipment and operator training, are crucial within hazardous regions. Also, regular education on tank pressurization risks and spill prevention increases refueling safety.
Equipment Modifications
Upgrading mobile refueling equipment to non-pressurized systems improves safety and reduces spill risks. These systems lower the chance of fuel spills, protecting the environment and reducing hazards.
Removing pressure also minimizes vapor release, lowering fire risks and keeping operators safe. Furthermore, installing fuel vents with surge protection prevents overflow during refueling. While rollover protection helps prevent spills if the vehicle moves suddenly or tips on uneven ground.
Policy and Standards Adjustments
Advocate for modified industrial regulations, promoting secure methods of non-pressurized fueling procedures. These methods reduce spills, vapor release, and fire risks by eliminating pressure.
Regulations should also include proven safety technologies like leak detection and shut-off systems. Moreover, regular assessments can help identify risks, ascertain compliance with safety laws, and maintain system performance.
Maintenance Programs
A proactive maintenance program for mobile refueling equipment will improve safety, compliance, and efficiency. Regular inspections help detect tank damage early, preventing leaks and environmental hazards. Whereas routine maintenance will extend equipment life by addressing minor issues before they become costly repairs.
In addition, you must hold scheduled inspections to make certain hoses, fittings, and tanks are in good condition. Also, verify that safety systems like leak detection and emergency shut-offs function properly to prevent accidents.
Key Takeaways
The safe process of refueling diesel vehicles remains critical because it safeguards both the environment and personnel from spills as well as fires and contamination. Refueling operations require strong safety protocols because standard risks exist during pressure control tank events as well as fuel drips and diesel cleaning in bath washers. Additional risks appear because of uneven terrain together, outdated standards, and insufficient training measures.
Beyond training all operators on fuel handling in hazardous areas, they must use equipment that includes non-pressurized systems to improve safety. The prevention of hazards also depends heavily on both scheduled equipment maintenance, policy revisions, and periodic inspections. By prioritizing safety, organizations can protect their personnel, and environment and adhere to regulatory compliance.
FAQs
