SCR catalytic converter Do not dispose of the spent SCR catalytic converter or its constituent parts into any wa- terways, storm drains or sanitary sewers. Any dust from the SCR catalytic converter should be removed using a vacuum cleaner with microfilter to minimize exposure. Make sure that the work surface is cleaned af- ter completed work; Vacuum first then swab. Make sure you clean your hands after work- ing with SCR catalytic converter to avoid in- gestion. Work done on the SCR catalytic converter may generate waste considered by the State of California to be a hazardous waste subject to Title 22, California Code of Regulations.
Before disposing of hazardous waste, review and follow all pertinent federal and California requirements. WARNING! The SCR catalytic converter contains vanadium pentoxide, a chemical known to the State of Cal- ifornia to cause cancer. Additional considerations when working on the SCR system Carry out work on the SCR catalytic convert- er in all well ventilated area. Use protective goggles and gloves if there is any risk of splashing or spraying of reductant or coolant. When engine is running, the exhaust system parts can reach such high temperatures that there is a risk of personal injury.
Make sure that the exhaust system temperature has de- creased to a suitable level before starting to work. The SCR system is heated by water from the engine cooling system. The cooling system runs at overpressure and when the engine is hot the coolant is hot. Do not open any hoses without first stopping the coolant flow in the hose. A P3 type respirator/filter mask or a type FFP3 fine dust musk, protective goggles and gloves should be used for any work where there is a risk of exposure to dust from the SCR catalytic converter. Use a disposable overall and dispose of it properly after machining. Eating, drinking or smoking while working is not permitted.
