4. First aid measures

4.1 First Aid

Inhalation Keep at rest. Move the exposed person to fresh air at once. If breathing is difficult, (trained
personnel should) give oxygen. Seek medical attention at once.

Ingestion Do NOT induce vomiting. Rinse mouth. Risk of product entering the lungs on vomiting after
ingestion. Never give anything by mouth to an unconscious person. Immediate medical
attention is required.

Skin contact Promptly wash contaminated skin with soap or mild detergent and water. Promptly remove
clothing if soaked through and wash as above. Burns: Flush with water immediately. While
flushing, remove clothes which do not adhere to affected area. Call an ambulance.
Continue flushing during transport to hospital. Chemical burns must be treated by a
physician.

Eye contact Hold eye open and rinse slowly and gently with water for 15-20 minutes. Remove contact
lenses, if present, after the first five minutes, then continue rinsing eye. Get immediate
medical attention.

4.2 Most important symptoms and effects, both acute and delayed

General advice Seek medical attention for all burns, regardless how minor they may seem. The severity of
the symptoms described will vary dependant of the concentration and the length of
exposure. If adverse symptoms develop, the casualty should be transferred to hospital as
soon as possible.

Main symptoms

Inhalation Please see Section 11. Toxicological Information for further information.

Ingestion Please see Section 11. Toxicological Information for further information.

Skin contact Please see Section 11. Toxicological Information for further information.

4.3 Indication of any immediate medical attention and special treatment needed

Notes to physician Treat symptomatically.

5. Fire-fighting measures

5.1 Extinguishing media

Suitable extinguishing media

Use dry chemical, CO2, Water spray mist or foam.

Extinguishing media which shall not be used for safety reasons

Do not use water jet.

5.2 Special hazards arising from the substance or mixture

Unusual fire and explosion hazards

FLAMMABLE LIQUID AND VAPOUR. Vapours are heavier than air and may spread along floors. Vapors may travel considerable
distance to source of ignition and flash back.

Hazardous combustion products

Fire or high temperatures create: Carbon oxides (COx), Nitrogen oxides (NOx), Chlorine, chlorine oxides, hydrogen chloride.

5.3 Advice for firefighters

Special protective equipment for fire-fighters

As in any fire, wear self-contained breathing apparatus and full protective gear.

Special Fire-Fighting Procedures

Containers close to fire should be removed immediately or cooled with water.

6. Accidental release measures

6.1 Personal precautions, protective equipment and emergency procedures

Do not get on skin or clothing. Wash thoroughly after handling. Do not breathe vapors or spray mist. Use personal protective
equipment. See also section 8.

6.2 Environmental precautions

The product should not be allowed to enter drains, water courses or the soil.

Environmental exposure controls

Avoid release to the environment. Local authorities should be advised if significant spillages cannot be contained.

6.3 Methods and materials for containment and cleaning up

Methods for containment

Prevent further leakage or spillage if safe to do so. Dyke far ahead of liquid spill for later disposal.

Methods for cleaning up

Use non-sparking tools and equipment. Contain and collect spillage with non-combustible absorbent material, (e.g. sand, earth,
diatomaceous earth, vermiculite) and place in container for disposal according to local/national regulations (see Section 13).

11. Toxicological information

11.1 Information on toxicological effects

Acute toxicity

Product information Toxic by inhalation, in contact with skin and if swallowed. Methanol is more toxic to humans
and primates than to most experimental animals, due to differences in how it is
metabolised. Non-primates do not appear to experience the acidosis or vision effects
observed in humans and primates.

Inhalation Toxic by inhalation. May cause drowsiness or dizziness. May cause respiratory
sensitization, an allergic reaction, on repeated exposure. May cause damage to organs
through prolonged or repeated exposure.

Eye contact May cause burns. May cause irreversible damage to eyes. Corrosive to the eyes and may
cause severe damage including blindness.

Skin contact Toxic in contact with skin. Causes severe skin burns. Components of the product may be
absorbed into the body through the skin. May cause systemic intoxication through skin
absorption. May cause sensitisation by skin contact.

Ingestion Toxic if swallowed. Intoxication can lead to a coma with metabolic acidosis that may be
fatal. Ingestion causes severe swelling, severe damage to the delicate tissue and danger of
perforation.

Unknown acute toxicity Not applicable.
