Safety Information and Updates

Diesel Exhaust Fluid (DEF) is an essential component of Selective Catalytic Reduction (SCR) systems used in modern diesel engines to reduce harmful nitrogen oxide (NOx) emissions. While DEF is non-toxic, non-flammable, and safe to handle, improper storage and use can compromise its effectiveness and potentially damage your vehicle’s emission system. Here are the best practices for the safe handling, storage, and use of DEF.

DEF is a solution made of 32.5% high-purity urea and 67.5% deionized water. It meets strict ISO 22241 standards to ensure quality and compatibility with SCR systems. It is important to keep DEF free of dirt, oil, fuel, and other substances. Even small contaminants can affect its performance and damage the SCR system. Use only dedicated DEF equipment for dispensing and storage to prevent contamination. DEF is not a fuel or fuel additive; it is injected into the exhaust stream to facilitate the chemical reaction that reduces NOx emissions.

Always use certified DEF that meets ISO 22241 standards. Off-spec or counterfeit DEF can cause system failures. DEF is corrosive to some metals, such as aluminum, copper, and zinc, so use materials like stainless steel or high-density polyethylene (HDPE) for storage and dispensing. You should store DEF in a cool, dry, and well-ventilated area. Check storage tanks, dispensing equipment, and DEF systems for leaks or damage regularly. While DEF is non-toxic, it can cause skin or eye irritation if mishandled. Use gloves and safety glasses when handling large quantities.

Ideal storage temperatures range from 12°F (-11°C) to 86°F (30°C). Exposure to extreme heat or freezing temperatures can degrade its quality. Should the DEF freeze in a truck when the truck is shut down, simply start the truck as normal, and the SCR heating system will quickly thaw the DEF, returning it to liquid form, and the vehicle will run as intended. DEF also degrades when exposed to direct sunlight. Use opaque or UV-resistant containers to protect it. DEF has a shelf life of about one year under optimal conditions.

Proper handling, storage, and use of DEF are crucial for maintaining its quality and ensuring the efficient operation of SCR systems. By following these best practices, you can help reduce emissions, avoid costly repairs, and ensure compliance with environmental regulations.

As winter brings colder temperatures and unpredictable weather, safely receiving fuel deliveries becomes crucial for our customers. At Dennis K. Burke, Inc. we consider Safety one of our top priorities. Here are essential tips from our Safety Department to ensure a smooth and secure process.

We kindly ask that before the delivery, make sure driveways, pathways, and delivery areas are clear of snow and ice. This helps the delivery driver access your location safely and reduces the risk of accidents. Identify a specific area for the driver to unload the product they’re delivering. Make sure this spot is well-marked and free from obstacles, ensuring the driver can deliver safely and efficiently.

Stay in touch. Keep us informed of any special instructions or access issues related to your property. Keeping communication open can help prevent delays and ensure timely, safe and accurate deliveries. Be aware of the weather forecast. If severe weather is predicted, consider scheduling your delivery in advance to avoid any disruptions. Planning ahead can help ensure you have enough fuel to last through winter storms.

If you’re a generator customer, please be sure the generator has a working gauge or whistle. Delivery drivers are not permitted to fill a tank without ensuring they know how much product will fit safely. Oftentimes our drivers arrive to fill generators and discover either the gauge is broken (i.e. not responding when fuel is delivered), or the tank is equipped with a whistle that does not sound. If the driver is unable to determine how much fuel is in the generator, the delivery will have to be stopped until the matter is resolved. This is to protect the customer’s property and avoid having a fuel spill.

Keep an emergency kit handy, including a flashlight and basic supplies, in case the delivery is delayed due to weather conditions. Being prepared can help you stay calm and safe. By following these simple tips, you can ensure a safe and efficient fuel delivery experience during winter months, helping you maintain comfort and safety throughout the season. On behalf of DKB Safety we want to wish all our customers a Safe, Happy, and Healthy Holiday Season.
