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.

Risk of explosion from explosive gas. Risk of poisoning and caustic burns from swallowing battery electrolyte. Risk of
injury through burns to skin and eyes from battery acid or when handling damaged lead-acid batteries

No fires, sparks, open flames or aDanger

gloves, clothing and glasses.
Only pour battery acid into
suitable and appropriately
marked containers.

Risk of explosion from
explosive gas. Risk of
poisoning and caustic burns
from swallowing battery
electrolyte. Risk of injury
through burns to skin and eyes
from battery acid or when
handling damaged lead-acid
batteries
Potential risks
Risk of explosion
When charging lead batteries with battery electrolyte
containing sulfuric acid, a highly explosive oxyhydrogen
gas mixture is created that ignites by means of fire, sparks,
open flames and smoking.
Risk of injury
The battery electrolyte contains diluted sulfuric acid that
causes caustic burns to the skin, eyes and mucous
membranes in the event of contact. Bonded electrolyte is
just as caustic as liquid electrolyte. Battery electrolyte mist
causes caustic burns to the eyes. If inhaled, this can result
in caustic burns to the mucous membranes and respiratory
paths. In the event of a short circuit from the battery
positive to ground, battery terminals and conductive objects
causing short circuit, e.g. tool or jewelry (watch band or

ring), become hot in seconds and red hot/liquid metal
sprays are released.
Risk of burn injuries
In the event of a short circuit from the battery positive to
ground, battery terminals and conductive objects causing
short circuit, e.g. tool or jewelry (watch band or ring),
become hot in seconds and cause burns.
Risk of poisoning
If battery electrolyte is swallowed, this can result in
symptoms of poisoning such as headache, dizziness,
stomach ache, respiratory paralysis, unconsciousness,
vomiting, caustic burns and cramps. Absorption of lead in
the body through contact with leaded components (battery
terminals, lead plates in damaged batteries) damages the
blood, nerves and kidneys; lead compounds are also toxic
for reproduction.

--------------------------------------------------------------------------Safety precautions/instructions
•

Wear acid-resistant gloves and clothing and safety
glasses with side guards.

•

Only charge lead batteries in well ventilated rooms with
appropriate voltage and appropriate current with
approved chargers, taking into account the instructions
of the battery and battery charger manufacturers.

•

No fire, sparks, open flames and smoking.

•

Switch on the battery charger only after connecting to
the terminals; switch off the battery charger before
disconnecting from the terminals.

•

Do not place any conductive objects on the battery and
do not wear any conductive jewelry (risk of short circuit).

•

Always disconnect the negative terminal first; always
connect the positive terminal first (risk of short circuit
caused by tool).

•

Strict caution is required when handling damaged
batteries (removing from vehicle damaged in accident)
because of the sharp edges on the fractured housing
and escaped electrolyte.

•

Keep batteries and battery electrolyte away from
unauthorized persons (especially children).

•

Only fill liquid battery electrolyte into suitable and
appropriately marked containers.

•

Only store, transport and install batteries with liquid
battery electrolyte horizontally, otherwise battery
electrolyte can escape from the degassing holes.

•

Ensure that at least one degassing hole at the battery is
not sealed, as otherwise overpressure builds that leads
to bursting of the battery.

•

Ensure proper connection of the degassing line to the
degassing hole.

•

Ensure the degassing line does not have any kinks and
is not blocked at any point.

•

Observe the instructions for use for the respective lead
batteries and the operator's manual of the vehicle.

•

The battery housing may become brittle over time,
therefore do not expose the battery to direct sunlight.

•

Discharged batteries may freeze and are thereby
damaged, therefore always store batteries at a location
protected against frost.

Notes on avoiding damage
through contamination and
foreign objects
Information on affected component parts
With each maintenance and repair work to the engine as
well as to the ancillary assemblies and detachable parts
comes the danger of property damage caused by
contamination and foreign bodies.

Topical note

g
Before assembling or finalization work all components
are to be checked for soiling, left-over foreign objects and
any fluids, and if any are found they are to be removed.

Particularly at risk are:

Information on cleaning

•

Exhaust gas turbocharger

For cleaning, use only clean tools and clean, lint-free rags.

•

Hot film mass air flow sensor

•

Compressor

•

Emission control system

Residues of cleaning agents and removed contaminants
must be cleared from the engine, ancillary assemblies and
detachable parts.

•

All components involved in gas exchange

Notes on removal/installation
Openings through which soiling or foreign objects are
introduced into the engine, its ancillaries or detachable
parts, must be sealed immediately.

p
Do not use compressed air for removing any soiling.
Otherwise, components (e.g. the hot-wire element of the
hot film mass air flow sensor) could be damaged or
contamination could enter the engine, ancillary assemblies
and detachable parts without being noticed.

For this purpose, suitable, clean covers and plugs or clean,
lint-free rags are to be used.
p
Do not forget to remove all covers, plugs or rags when
assembling or when finalizing the work.
This avoids any damage and complaints about engine
running characteristics.

AdBlue®

Topical note

Tasks of AdBlue®

CAS (Chemical Abstracts Service) no.: 57-13-6

AdBlue® serves to convert nitrogen oxides into water vapor
and nitrogen.

Marking

Chemical characterization and composition of
AdBlue®
The urea content is 32.5%. AdBlue® consists of urea
dissolved in demineralized water. AdBlue® is not an
additive.
Chemical formula: H2N-CO-NH2

AdBlue® dispensers are marked with the standard
designation ISO 22241 or with the trade designations
AdBlue® or Diesel Exhaust Fluid (DEF).
Transport
In vehicles with BlueTEC technology, AdBlue® is carried in
a tank.

Molecular weight (urea): 60.06 g/mol
--------------------------------------------------------------------------Physical and chemical properties of AdBlue®
State: Liquid
Color: Colorless, clear, light-yellow
Odor: Slight ammonia odor

engine oil, transmission oil, fuel, hydraulic fluid and brake
fluid and not used in the same containers and collecting
bowls. The smallest amounts of AdBlue® can damage
thermostats or temperature sensors.

pH value: 10 (aqueous solution, 10 %)

Operating fluids which contain traces of AdBlue® must not
be used again.

Crystallization temperature: –11 °C / 12 °F

Handling contaminated AdBlue®

Boiling point: 103 °C / 217 °F
Auto-ignition temperature: Not spontaneously inflammable
Density: approx. 1.09 g/cm3 at 20 °C / 68 °F
Viscosity (dynamic): approx. 1.4 mPa*s at 25 °C / 77 °F
Handling contaminated operating fluids
It is essential that AdBlue® be kept separate from other
operating fluids, fuels and lubricants such as coolant,

AdBlue® must be checked as per the repair instructions
before every fill. Individual components of the exhaust
aftertreatment system already react very sensitively with
even the smallest traces of contaminants in AdBlue®.
When handling AdBlue® it is important, therefore, to
always use clean containers and collecting bowls which are
only reserved for this purpose. Contaminated AdBlue®
must not be used again.

--------------------------------------------------------------------------Handling contaminated materials

Handling contaminated tools

It is essential that AdBlue® does not come into contact with
materials used in the interior of the vehicle. AdBlue®
exposed to air passes within just a few hours from a liquid
state into the crystalline state and can therefore damage
and destroy contaminated surfaces.
