Risk Of Burn Injuries And Scalding When Working At Adblue Lines And The Components Attached To Them. Risk Of Injury To Skin And Eyes When Handling Adblue. Risk Of Poisoning Caused By Swallowing Adblue - AS14.40-Z-0001-01A

Engine all (4xWD, CAR, Heavy transporter, Light transporter) 

Pour AdBlue into suitable containers only. Wait until the pressure is released before starting any work on the exhaust aftertreatment system.

Potential risks 

Risk of burn injuries and scalding 

The AdBlue® lines and all components attached to them are under pressure during operation and remain so after the engine is switched off and may be hot. There is a risk of burn injuries. There is a risk of scalding caused by escaping hot AdBlue® when the line system is opened.

Risk of injury 

There is a risk of skin irritation and eye damage on contact with AdBlue®.

Risk of poisoning 

There is a risk of poisoning if AdBlue® is swallowed.

Rules of conduct 

• On vehicles with electrical delivery pump, the AdBlue® is pumped from the line back into the AdBlue® tank after the engine is switched off.

  On vehicles with a compressed air system, individual lines are flushed with compressed air after the engine is switched off. The engine must therefore be switched off for at least 5 minutes before work on the exhaust aftertreatment system may begin.

• Open connections and plugs on the system components slowly. Cover the connecting point with rags when opening.
• Only pour AdBlue® into marked containers specially designated for the purpose. Do not pour AdBlue® into drinking containers.
• Wipe up any AdBlue® spills immediately as there is a high risk of someone slipping.

Safety precautions for handling removed parts and working under the vehicle 

• Wear suitable protective gloves
• Wear protective clothing
• Wear safety glasses

First aid measures 

Contact with skin: Wash the affected skin areas with plenty of clean water. Change wetted clothing as quickly as possible.

Contact with eyes: In the event of contact with eyes, immediately rinse eyes thoroughly with plenty of clear water; contact an eye doctor if necessary.

Ingestion: rinse mouth with clean water and drink large quantities of water. Immediately seek medical assistance.

Firefighting measures 

AdBlue® is not combustible. NH₃ (ammonia) can be released in the event of fire, causing a risk of poisoning. Firefighting measures must therefore be suited to the surroundings.
