1.2.4.13 After-treatment system
The selective catalytic reduction (SCR) after-treatment system contains
vanadiumpentoxide . Vanadiumpentoxide can be hazardous.
The SCR after-treatment system is installed in the muffler. The system is not
hazardous to health under normal use and handling.
When the SCR after-treatment system is handled in such a way that there is a
risk of exposure to dust, safety precautions must be taken. Such work includes,
for example, opening the after-treatment system, machining and disposing of the
after-treatment system.
Safety instructions for work involving the SCR after-treatment system
• Inhalation: If dust is inhaled, the affected person must be immediately taken
to breathe plenty of fresh air. If a considerable amount of dust has been
inhaled, seek medical help.
• Contact with eyes: Rinse eyes immediately with water. If irritation continues,
seek medical help.
• Contact with skin: Wash with soap and water. Take off contaminated clothes.
• Swallowing: If you swallow a large amount, drink plenty of water and try to
vomit. Seek medical help.
Environmental hazards
Vanadiumpentoxide is toxic to aquatic organisms and may cause long-term
adverse effects in the aquatic environment.
Precautions to protect the environment
All dust and spillage must be gathered in a container for recycling or disposal in
accordance with local regulations. They must not be allowed to enter water
systems or the general waste management system.
When an SCR after-treatment system is no longer used, it must be disposed of in
accordance with applicable EU regulations, national regulations or local
regulations. The EU classifies the parts of the SCR after-treatment system as
hazardous to the environment.
