Things to know about spilled Diesel Exhaust Fluid (DEF)
If urea solution comes into contact with the skin, rinse with plenty of water and remove
contaminated clothing.
If urea solution comes into contact with the eyes rinse for several minutes and call for
medical help if necessary.
If inhaled breathe fresh air and call for medical help if necessary.
Do not allow the DEF solution to come into contact with other chemicals.
The DEF solution is not flammable. If the DEF solution is exposed to high temperatures for
long periods of time, it breaks down into ammonia and carbon dioxide.
The DEF solution is corrosive to certain metals, including copper and aluminium. This is
similar to the corrosion caused by salt water.
If the DEF solution is spilled onto the vehicle, wipe off the excess and rinse with water.
Spilled DEF solution can form concentrated white crystals on the vehicle. Rinse off these
crystals with water.
Note:
Do not flush DEF spills into the normal drain system.
WARNING
DEF spilt onto hot components will
quickly vaporize. Turn your face away!
Diesel Exhaust Fluid (DEF) Consumption
DEF consumption is related to fuel consumption. A bus may travel 225-300 miles (360 —
480 kilometers) or more on one gallon (3.8 liters) of DEF. A gauge much like a fuel gauge
will indicate the level of DEF in the tank. A DEF low-level warning activates when DEF is
low. If a driver runs out of DEF completely, vehicle power will be reduced to derate mode.
When the DEF tank is refilled, the engine will resume normal power.
Note:
DEF tanks are sized for a two to one fuel to DEF ratio in order to meet US 2010
requirements.
