Safety Precautions When Working On SCR System: Notes

Note the following when working on the SCR system:

The reducing agent increases the risk of injury

Reducing agents may cause eye and skin irritation as well as injury to the respiratory system and possible poisoning.

-- Wear protective eyewear.

-- Wear safety gloves.

-- Wear protective work clothing.

-- Make sure there is a fresh air supply. Turn on exhaust extraction when in closed spaces.

Risk of damage due to reducing agent

If any reducing agent contacts the trim or body components, the reducing agent can crystallize after a period of time and damage the surface.

-- Make sure the reducing agent does not contact any trim or vehicle body components.

-- If any contact occurs on surfaces, remove the reducing agent immediately using water and a towel.

Note the following when removing or installing any components of the SCR system:

• The reducing agent tank must be empty when working on the selective catalytic reduction system. When the reducing tank needs to be emptied, read the respective procedure description.
