Safety Precautions When Working On SCR System: Notes
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.
