SCR System Safety Precautions: Notes
Pay attention to the following when working on the selective catalytic reduction system:
WARNING:
The reducing agent can cause skin irritation:
- Avoid contact with skin and eyes! Wear protective gloves!
- If reducing agent should get on your skin, wash it off immediately with soap and water.
- If reducing agent gets in your eye, rinse the eye for several minutes with water.
- Never inhale or swallow the reducing agent!
- Should you swallow any reducing agent, rinse your mouth, drink plenty of water and contact a doctor immediately.
- Make sure the reducing agent does not come into contact with clothing or the vehicle body.
- If this occurs, wash immediately with clean water and then dry with a lint-free cotton cloth.
- If the reducing agent has already crystallized, use warm water and a sponge.
- Reducing agent that is not removed will crystallize and can damage the affected surface.
Danger due to reducing agent leaking out:
- To prevent large amounts of reducing agent from leaking out when opening the metering line, wait for the recirculation process to complete, refer to Reducing Agent, Automatic Regeneration .
Note the following when removing or installing any components of the SCR-System:
- The reducing agent tank must be empty when working on the SCR-system. When the reducing tank needs to be emptied, read the respective work description. Drain the reducing agent tank, refer to REDUCING AGENT TANK, DRAINING .
