Safety Information and Updates

Diesel Exhaust Fluid (DEF) is a critical component of modern diesel engines equipped with Selective Catalytic Reduction (SCR) systems. DEF helps reduce harmful nitrogen oxide (NOx) emissions by converting them into harmless nitrogen and water vapor. While DEF is non-toxic and non-flammable, improper handling, storage, or use can lead to equipment damage, safety issues, and costly downtime. Following best practices ensures both worker safety and reliable engine performance.

Safe Handling of DEF

DEF is a clear, colorless solution made of 32.5% urea and 67.5% deionized water. Although it is considered non-hazardous, basic safety precautions should always be followed. Avoid direct contact with skin and eyes, as DEF can cause mild irritation and leaves crystalline residue when it dries. Wear gloves and eye protection when transferring or dispensing DEF, especially in bulk operations.

Spills should be cleaned promptly. DEF is slippery and can create slip hazards on walking surfaces. Use absorbent materials and rinse the area with water after cleanup. Never mix DEF with diesel fuel, gasoline, or any other chemicals—contamination can damage SCR systems and cause engine derates or shutdowns.

Proper Storage Practices

DEF must be stored correctly to maintain its quality and effectiveness. Use only approved containers made from materials such as stainless steel or high-density polyethylene (HDPE). Never store DEF in containers previously used for fuel, oil, or chemicals.

Temperature control is critical. DEF freezes at approximately 12°F (-11°C). While freezing does not damage DEF, repeated freeze-thaw cycles should be minimized. Store DEF between 23°F and 77°F whenever possible. Prolonged exposure to temperatures above 86°F can degrade DEF quality and shorten shelf life.

Keep storage containers sealed to prevent contamination from dust, dirt, or moisture. DEF should be protected from direct sunlight and stored in a clean, dry area. Clearly label all containers to avoid accidental misuse.

Safe and Correct Use

Only use DEF that meets ISO 22241 specifications. Using poor-quality or contaminated DEF can result in SCR system failure, warning lights, reduced engine power, or costly repairs. Always verify that dispensing equipment is clean and dedicated exclusively to DEF.

Never add DEF to the diesel fuel tank—DEF must only be added to the designated DEF tank. Likewise, diesel fuel must never be introduced into the DEF system. Even small amounts of contamination can cause severe damage.

Operators should follow manufacturer guidelines for refilling intervals and quantities. If a DEF warning light or fault occurs, address it promptly to avoid engine derate conditions.

While Diesel Exhaust Fluid is safe to handle when proper procedures are followed, attention to handling, storage, and use is essential. Clean equipment, temperature control, contamination prevention, and proper training all play a role in protecting employees and ensuring reliable vehicle operation. By following these best practices, organizations can maintain compliance, reduce downtime, and support a safer work environment.

Our Dennis K. Burke Inc. dispatch team operates seamlessly through the integration of our advanced tank monitoring program, ensuring precise communication with our dedicated truck drivers. This technology enables real-time tracking of tank levels, guaranteeing that our drivers are equipped with the correct quantities of fuel and lubricants required. Once on a customer's site, our drivers must employ a secondary method to confirm that the correct product will fit the specific requirements. This includes utilizing tools like gauges and listening for characteristic whistles, ensuring an extra layer of accuracy and reliability. This dual-approach strategy not only exemplifies our commitment to precision but also underscores our dedication to meeting and exceeding customer expectations at every step of the process. Tank monitoring is a cornerstone of responsible and efficient operations across various industries. By providing real-time data and enabling early defect detection, it ensures both safety and sustainability.

1. Preventing Overfills and Spills
   One of the primary benefits of tank monitoring is its ability to prevent overfills. Overfilled tanks can lead to spills, which not only result in environmental harm but can also pose serious safety risks. Tank monitoring systems use sensors and technology to provide real-time data, allowing for precise control of filling levels and preventing accidents.

2. Minimizing Environmental Impact
   Environmental responsibility is a paramount concern across industries. Tank monitoring ensures that storage facilities operate within their designated capacities, reducing the likelihood of leaks, spills, and contamination of soil or water bodies.

3. Enhancing Operational Efficiency
   Efficient resource management is key to any successful operation. With tank monitoring, businesses can optimize their inventory levels, minimizing unnecessary refills and associated costs. Additionally, it enables timely scheduling of maintenance, ensuring that tanks are in good condition and preventing unexpected downtime.

4. Early Detection of Leaks and Defects
   Regular monitoring allows for the early detection of leaks or defects in tanks. Whether caused by corrosion or faulty equipment, identifying problems promptly can prevent costly repairs, safeguarding both the environment and personnel.

5. Improved Inventory Management
   Efficient inventory management is crucial for businesses dependent on stored materials. Tank monitoring systems provide accurate, real-time data on inventory levels, enabling timely reordering and avoiding shortages or excess stock. This, in turn, leads to streamlined logistics and cost savings.

6. Compliance with Regulatory Standards
   Many industries are subject to strict regulatory standards governing the storage and handling of materials. Tank monitoring helps ensure compliance with these regulations, providing documentation of tank levels, leak detection, and maintenance schedules.

8. Enhancing Worker Safety
   Tank monitoring minimizes the need for manual inspections, which can be hazardous for workers. By utilizing automated monitoring systems, employees are exposed to fewer risks associated with climbing tanks or working in potentially hazardous environments.
9. Real-time Data and Remote Monitoring
   Modern tank monitoring systems provide real-time data accessible from virtually anywhere. This remote monitoring capability allows for prompt decision-making and intervention, even when staff are not on-site.

Embracing tank monitoring not only safeguards the environment and personnel but also contributes to a more cost-effective and sustainable operation. It's a proactive investment in the safety, efficiency, and reputation of any business reliant on tank storage systems!
