Never give anything by mouth to an unconscious person.
If unconscious, place in recovery position and seek medical
advice.
Move out of dangerous area.
Show this material safety data sheet to the doctor in
attendance.
Do not leave the victim unattended.
Symptoms of poisoning may appear several hours later.
No artificial respiration, mouth-to-mouth or mouth to nose. Use
suitable instruments/apparatus.
If inhaled
: Administer oxygen if breathing is difficult or cyanosis is
observed.
Call a physician immediately.
If breathed in, move person into fresh air.
If not breathing, give artificial respiration.
Contact a poison control center.
Respiratory tract burning possible if aerosols are inhaled.
Call a physician or poison control center immediately.
If unconscious, place in recovery position and seek medical
advice.
Keep respiratory tract clear.
In case of skin contact
: If symptoms persist, call a physician.
Immediate medical treatment is necessary as untreated
wounds from corrosion of the skin heal slowly and with
difficulty.
In case of contact, immediately flush skin with plenty of water
for at least 15 minutes while removing contaminated clothing
and shoes.
Wash contaminated clothing before re-use.
If on skin, rinse well with water.
If on clothes, remove clothes.
In case of eye contact
: Small amounts splashed into eyes can cause irreversible

If symptoms persist, call a physician.
Most important symptoms
and effects, both acute and
delayed
: Harmful if swallowed or in contact with skin.
May be fatal if swallowed and enters airways.
Causes serious eye damage.
Toxic if inhaled.
May cause respiratory irritation.
May cause cancer.
May cause damage to organs through prolonged or repeated
exposure.
Causes severe burns.
Protection of first-aiders
: First Aid responders should pay attention to self-protection
and use the recommended protective clothing
Notes to physician
: Treat symptomatically and supportively.
SECTION 5. FIRE-FIGHTING MEASURES
Suitable extinguishing media
: Water spray jet
Alcohol-resistant foam
Carbon dioxide (CO2)
Dry chemical
Unsuitable extinguishing
media
: High volume water jet
Specific hazards during fire
fighting
: Risk of explosion if heated under confinement.
Possible emission of gaseous decomposition products may
lead to a dangerous pressure build-up.
Avoid confinement.
Contact with incompatible materials or exposure to
temperatures exceeding SADT may result in a self-
accelerating decomposition reaction with release of flammable
vapors which may auto-ignite.
The product burns violently.
Flash back possible over considerable distance.

Vapors may form explosive mixtures with air.
The product will float on water and can be reignited on surface
water.
Cool closed containers exposed to fire with water spray.
Specific extinguishing meth-
ods
: Do not use a solid water stream as it may scatter and spread
fire.
Remove undamaged containers from fire area if it is safe to do
so.
Use water spray to cool unopened containers.
Further information : Use extinguishing measures that are appropriate to local
circumstances and the surrounding environment.
Use a water spray to cool fully closed containers.
Collect contaminated fire extinguishing water separately. This
must not be discharged into drains.
Fire residues and contaminated fire extinguishing water must
be disposed of in accordance with local regulations.
Special protective equipment
for fire-fighters
: Wear self-contained breathing apparatus for firefighting if
necessary.
Use personal protective equipment.
SECTION 6. ACCIDENTAL RELEASE MEASURES
Personal precautions, protec-
tive equipment and emer-
gency procedures
: Follow safe handling advice and personal protective
equipment recommendations.
Beware of vapors accumulating to form explosive
concentrations. Vapors can accumulate in low areas.
Use personal protective equipment.
Ensure adequate ventilation.
Remove all sources of ignition.
Evacuate personnel to safe areas.
Never return spills in original containers for re-use.
Treat recovered material as described in the section "Disposal
considerations".
Environmental precautions
: Prevent product from entering drains.
Prevent further leakage or spillage if safe to do so.
If the product contaminates rivers and lakes or drains inform
respective authorities.
Methods and materials for
containment and cleaning up
: Contact with incompatible substances can cause
decomposition at or below SADT.
Clear spills immediately.
Suppress (knock down) gases/vapors/mists with a water spray
jet.
To clean the floor and all objects contaminated by this
material, use plenty of water.
Soak up with inert absorbent material.

Remarks
: The data about break through time/strength of material are
standard values! The exact break through time/strength of
material has to be obtained from the producer of the
protective glove. Choose gloves to protect hands against
chemicals depending on the concentration and quantity of the
hazardous substance and specific to place of work.
For special applications, we recommend clarifying the
resistance to chemicals of the aforementioned protective
gloves with the glove manufacturer. Wash hands before
breaks and at the end of workday.
Eye protection
: Ensure that eyewash stations and safety showers are close
to the workstation location.
Please follow all applicable local/national requirements when
selecting protective measures for a specific workplace.
Always wear eye protection when the potential for inadvertent
eye contact with the product cannot be excluded.
Tightly fitting safety goggles
Please wear suitable protective goggles. Also wear face
protection if there is a splash hazard.
Skin and body protection
: Select appropriate protective clothing based on chemical
resistance data and an assessment of the local exposure
potential.
Additional body garments should be used based upon the
task being performed (e.g., sleevelets, apron, gauntlets,
disposable suits) to avoid exposed skin surfaces.
Wear as appropriate:
Flame retardant antistatic protective clothing.
Protective measures
: The type of protective equipment must be selected according
to the concentration and amount of the dangerous substance
at the specific workplace.
Hygiene measures
: Avoid contact with skin, eyes and clothing.
Keep away from food and drink.
When using do not eat or drink.
When using do not smoke.
Wash hands before breaks and immediately after handling
the product.
