Diesel exhaust fluid (DEF) is commonly known as AdBlue. It is an aqueous urea solution used in modern diesel engine trucks to help reduce their nitrogen oxide emissions. It quite common for AdBlue to be handled, stored and dispensed wherever diesel trucks and engines are fuelled or maintained. With this comes the risk of AdBlue leaks, drips or spills, which not only have the potential to harm the environment, but may affect safety in the workplace. An appropriate Spill Kit is essential to contain and control the spill within a certain area. Such a spill kit will not react with the liquids it is designed to control and allows responders to confidently deal with the leak or spillage. Diesel refuelling sites typically use oil and fuel spill kits which contain hydrophobic (water-repellent) absorbents. These absorbents are not suitable for use with AdBlue. AdBlue Spill Kits are conveniently housed in blue wheelie bins and bags and contain a variety of all-liquid, polypropylene absorbents colour-coded grey (differentiating them from our white oil and fuel absorbents).
