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.

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
smoking. Wear acid-resistant
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.

--------------------------------------------------------------------------First aid measures
Contact with eyes
•

Rinse eyes immediately with plenty of water.

Contact with skin
•

Remove wet clothing.

•

Immediately neutralize battery electrolyte on the skin or
clothing with acid neutralizer or soapy water and rinse
off with plenty of water.

•

Wash off lead on the skin immediately with water and
soap.

Swallowing battery electrolyte
•

Have the person affected drink plenty of water with
activated charcoal supplement.

As a general rule, the person affected should consult a
medical service or physician after first aid has been
rendered.
Fire protection measures

Risk of injury caused by contact with battery gel when handling damaged lead-gelbatteries

No fires, sparks, open flames or aWarning
smoking. Wear acid-resistant
gloves, clothing and glasses.

Risk of injury caused by
contact with battery gel when
handling damaged leadgelbatteries
Potential risks
Risk of poisoning
Swallowing battery gel can cause symptoms of poisoning
such as headaches, dizziness, stomach aches, respiratory
paralysis, unconsciousness, vomiting, caustic burns and
cramps.
The absorption of lead in the body can cause damage to
blood, nerves and kidneys; in addition, lead compounds are
considered to represent a reproductive hazard.
Risk of injury
The bonded electrolyte set free is just as caustic as a
liquid electrolyte that can cause heavy caustic burns to skin
and eyes. Strict caution is required when handling
damaged lead-gel batteries (e.g. removing from vehicle
damaged in accident) because of the sharp edges on the
fractured housing and direct contact with the lead plates.

•

Do not place any tool or other conductive object on the
lead-gel battery (risk of short circuit!).

•

Disconnect and remove lead-gel batteries for charging.

•

Always disconnect the negative terminal first and
always connect the positive terminal first .

•

Only switch on the battery charger after connecting to
the terminals and switch off before disconnecting.

•

Keep lead-gel batteries away from unauthorized
persons (especially children).

•

Pay attention to instructions for use of the particular
lead-gel battery and the operator's manual for the
vehicle.

•

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

•

Only pour acid gel into suitable and appropriately
marked containers.

Safety precautions and rules of conduct

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.
