AdBlue is a simple and non-hazardous product. However, there are some clear rules to follow when using the solution because it is used with an SCR catalyst that is extremely sensitive to impurities.
                            
                            
                            
                                
It is essential to prevent AdBlue contamination to ensure your SCR system functions correctly, and also to avoid expensive repair costs. For optimum performance of your vehicle (large goods vehicle, tractor, light goods vehicle, van, bus, coach, car…), never add anything to your AdBlue as even the addition of water could damage the catalyst in your SCR system.

Always pour AdBlue into the AdBlue tank. Both the nozzle pistol and filler cap of the tank are clearly markedOnly use AdBlue equipment when storing or refilling AdBlueKeep your AdBlue equipment clean and free from dust or dirtEnsure your AdBlue tank and container seals remain intactUse demineralised water (or AdBlue) when cleaning internally or priming AdBlue equipmentProtect against misuse by not mixing with tap water, fuel, oil or other liquidsWear protective clothing if you are handling large quantities of AdBlue with the risk of a spillIf you spill AdBlue on the ground, in a vehicle or on a painted surface, rinse thoroughly with waterProtect from extreme temperatures. AdBlue freezes at an ambient temperature of 12˚F or -11˚CGently warm the container to melt the AdBlue if it freezes in its storage container. AdBlue can be used again, once thawed, as it returns to its original stateKeep your AdBlue out of direct sunlightStore below an ambient temperature of 30˚C as AdBlue can start to decomposeChill your AdBlue container if it becomes over heated by spraying the sealed container with water | 
Do not fill AdBlue into the diesel tankDo not fill diesel into the AdBlue tankDo not fill the AdBlue tank with water or any other liquidDo not mix AdBlue with other liquids – it is not an additiveDo not use AdBlue if contaminated with tap water or other substances such as diesel fuelAvoid spilling AdBlue on the ground as the surface may become slippery or the concrete or brickwork could be effectedDo not leave spilt AdBlue unwashedDo not operate your vehicle without AdBlue. It is illegal to do so, and will result in extra downtimeDo not use other substances other then AdBlue eg Urea Solutions. Costly damage may occur in the SCR systemDo not over-ride the system as this may affect your warranty, it is illegal and may also put your vehicle into a “limp home type” modeDo not use dirty equipment, such as funnels, jugs or oil containers for refilling AdBlueDo not store AdBlue in direct sunlight |
