Diesel Exhaust Fluid handling procedures are essential for your safety and to maintain the quality of the product. Although DEF is a non-hazardous material, it should still be handled with care.
For use in all vehicles with Selective Catalytic Reduction (SCR) systems, DEF is manufactured with technically pure urea and de-ionized water, meeting:
- Water grade 3 of ISO 3696
- All 18 parameters of ISO 22241
- DIN 7007:2005 standards
HANDLING DEF: DO'S AND DON'TS
- DO periodically clean the pump nozzle after filling by dipping the nozzle into a tub of clean water.
- DO avoid overfilling; DEF can be difficult to clean up if spilled on the vehicle, dispenser or floor.
- DO only use API certified DEF from companies who are also ISO certified. If filling at a retail location, ask if the product is API approved.
- DO only use dedicated pumps, tanks, containers and delivery equipment for DEF.
- DO only use designated equipment designed for use with DEF.
- DO educate drivers and mark tanks on trucks to ensure DEF is not added to diesel fuel.
- DON’T ever add DEF to the diesel fuel.
- DON’T use DEF from suppliers who do not have API certification.
- DON’T use DEF from suppliers who do not adhere to ISO standards.
- DON’T use discolored DEF.
- DON’T use DEF with visible particles floating in the fluid.
- DON’T allow DEF to contact equipment containing materials such as copper, iron, zinc, aluminum or magnesium.
- DON’T wait to clean up spilled DEF; it should be cleaned up as soon as possible.
