Guidance on Safe Use

First-aid measures

General advice:

Move out of dangerous area.
Consult a physician.
Treat symptomatically.
Get medical attention if symptoms occur.

Protection of first-aiders:

First Aid responders should pay attention to self-protection
and use the recommended protective clothing.
Avoid inhalation, ingestion and contact with skin and eyes.
No action shall be taken involving any personal risk or without
suitable training.
It may be dangerous to the person providing aid to give
mouth-to-mouth resuscitation.

If inhaled:

If inhaled, remove to fresh air.
Get medical attention if symptoms occur.

In case of skin contact:

Immediate medical treatment is necessary as untreated
wounds from corrosion of the skin heal slowly and with
difficulty.
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
tissue damage and blindness.
In the case of contact with eyes, rinse immediately with plenty
of water and seek medical advice.
Continue rinsing eyes during transport to hospital.
Remove contact lenses.
Keep eye wide open while rinsing.
If eye irritation persists, consult a specialist.

 

If swallowed:

Keep respiratory tract clear.
Do NOT induce vomiting.
Never give anything by mouth to an unconscious person.
If symptoms persist, call a physician.
Take victim immediately to hospital.

Fire-fighting measures

5.1 Extinguishing media
Suitable extinguishing media:

Water spray
Alcohol-resistant foam
Carbon dioxide (CO2)
Dry chemical

Unsuitable extinguishing media:

Exercise caution when using a high volume water jet as it may
scatter and spread fire

5.2 Special hazards arising from the substance or mixture
Specific hazards during firefighting:

Do not allow run-off from fire fighting to enter drains or water
courses.

Hazardous combustion products:

No hazardous combustion products are known

5.3 Advice for firefighters
Special protective equipment for firefighters:

Wear self-contained breathing apparatus for firefighting if
necessary.

Specific extinguishing methods:

Use extinguishing measures that are appropriate to local
circumstances and the surrounding environment.

Further information:

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.
For safety reasons in case of fire, cans should be stored
separately in closed containments.
Use a water spray to cool fully closed containers.

Accidental release measures

6.1 Personal precautions, protective equipment and emergency procedures
Personal precautions:

Use personal protective equipment.
Ensure adequate ventilation.
Remove all sources of ignition.
Evacuate personnel to safe areas.
Beware of vapours accumulating to form explosive
concentrations. Vapours can accumulate in low areas.

6.2 Environmental precautions
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.

6.3 Methods and material for containment and cleaning up
Methods for cleaning up:

Neutralise with acid.
Contain spillage, and then collect with non-combustible
absorbent material, (e.g. sand, earth, diatomaceous earth,
vermiculite) and place in container for disposal according to
local / national regulations.

Handling and storage

7.1 Precautions for safe handling
Advice on safe handling :

Do not breathe vapours/dust.
Avoid contact with skin and eyes.
Smoking, eating and drinking should be prohibited in the
application area.
Take precautionary measures against static discharges.
Open drum carefully as content may be under pressure.
To avoid spills during handling keep bottle on a metal tray.
Dispose of rinse water in accordance with local and national
regulations.

Advice on protection against fire and explosion:

Do not spray on a naked flame or any incandescent material.
Take necessary action to avoid static electricity discharge
(which might cause ignition of organic vapours). Use only
explosion-proof equipment. Keep away from open flames, hot
surfaces and sources of ignition.

Hygiene measures :

When using do not eat or drink. When using do not smoke.
Wash hands before breaks and at the end of workday.

7.2 Conditions for safe storage, including any incompatibilities
Requirements for storage areas and containers:

No smoking. Keep container tightly closed in a dry and wellventilated
place. Containers which are opened must be
carefully resealed and kept upright to prevent leakage.
Observe label precautions. Keep in properly labelled
containers.

Advice on common storage:

Do not store near acids.

Further information on storage stability:

Stable under normal conditions.
