First-aid measures

4.1. Description of first aid measures

General information:

Remove/Take off immediately all contaminated clothing. Pay attention to self-protection.

In case of unwellness, call a physician. Show this safety data sheet to the physician.

After inhalation:

Remove affected person to fresh air. In case of unwellness, seek medical advice.

After skin contact:

Immediately wash with water and soap and rinse thoroughly.

If irritation persists or rash occurs, consult a physician.

After eye contact:

Rinse opened eye for several minutes under running water. In irritation persists, consult an ophthalmologist.

After swallowing:

Thoroughly rinse mouth with water and immediately call a physician or poison centre.

Do not induce vomiting.

If unconscious place in recovery position and call a physician immediately.

Never give anything by mouth to an unconscious person.

4.2. Most important symptoms and effects, both acute and delayed

Skin contact: Allergic reactions, irritating effects.

After swallowing: Hydrolysis leads to formation of methanol.

Symptoms: vertigo, nausea, headache, convulsions, sight disorder,

acidosis.

4.3. Indication of any immediate medical attention and special treatment needed

Treat symptomatically (decontamination, vital functions).

Notes for the doctor: treatment of methanol poisoning may require use of ethanol.

Fire-fighting measures

5.1. Extinguishing media

Suitable extinguishing media: Water spray, alcohol resistant foam, dry powder, carbon dioxide (CO2).

Fight larger fires with water spray or alcohol-resistant foam.

Use fire extinguishing methods suitable to surrounding conditions.

Unsuitable extinguishing media which must not be uses for safety reasons: Strong water jet.

5.2. Special hazards arising from the substance or mixture

Substance is highly flammable. Formation of explosive vapour/air mixtures possible.

Vapours are heavier than air and may spread along the floor.

Hazardous decomposition products: In case of fire, formation of toxic gases/vapours is possible, e.g. carbon monoxide, carbon dioxide.

5.3. Advice for firefighters

If possible, remove endangered containers out of the danger area. Heating leads to pressure increase and danger of rupture/explosion. Cool endangered containers with water spray.

Special protective equipment for fire fighters:

Full protective equipment. Wear self-contained breathing apparatus.

If possible, remove endangered containers out of the danger area. Heating leads to pressure increase and danger of rupture/explosion.

Sufficient measures must be taken to retain water used for extinguishing.

Ignition residues and contaminated water must be disposed of in conformity with local regulations.

Accidental release measures

6.1. Personal precautions, protective equipment and emergency procedures

Do not breathe gas/mist/vapours/spray. Avoid contact with the substance.

Remove all sources of ignition. Take precautionary measures against electrostatic discharges.

Ensure sufficient ventilation. Vapours are heavier than air.

Evacuate personnel to safe areas. Beware of vapours accumulating to form explosive concentrations. Vapours can accumulate in low areas.

Avoid formation of aerosols.

Wear personal protective equipment (see Section 8).

Keep unprotected persons away.

6.2. Environmental precautions

Prevent further leaking/release, if this is safely possible.

Do not allow to enter into surface water or drains.

Do not allow to enter into soil.

6.3. Methods and material for containment and cleaning up

Bunding of bigger quantities and pumping into suitable containers.

Minor quantities: soak up with inert absorbent (e.g. kieselguhr or universal binder).

Collect in closed and suitable containers for recycling or disposal.

Contaminated material: dispose of as waste according to section 13.

6.4. Reference to other sections

Safe handling: see Section 7. Personal protective equipment: see Section 8. Disposal: see Section 13 of SDS.

8.2. Exposure controls

8.2.1. Appropriate engineering controls

Technical measures and appropriate working procedures should be given priority over the use of personal protective equipment. See section 7.

8.2.2 Individual protection measures

Personal protective equipment:

Eye protection: Tightly sealed goggles (EN 166)

Protection of hands:protective gloves.

To avoid skin problems, reduce the wearing of gloves to the required minimum.

The protective gloves must comply with the specifications of EC-Directive 89/686/EEC and the corresponding norm EN 374 (in connection with DIN EN 420 and DIN EN 388).

The glove material has to be impermeable and resistant to the product/ the substance.

Due to missing tests no recommendation to the glove material can be given for the product / the chemical mixture.

Selection of the glove material on consideration of the penetration times, rates of diffusion and the degradation.

Glove material:

The selection of suitable gloves does not only depend on the material, but also on further quality characteristics and varies from manufacturer to manufacturer.

Penetration time of glove material:

The exact break through time has to be found out by the manufacturer of the protective gloves and has to be observed.

Body protection:protective clothing.

Protective clothing needs to be selected specifically for the workplace, depending on the concentrations and

quantities of the hazardous substances handled.

Respiratory protection:

Not necessary if exhaust ventilation at the workplace is working well.

Respiratory protection:is needed if technical suction / ventilation measures are not possible or not sufficient, and if treshold limits are exceeded.

In case of short-term or low exposure: use filtering device. Respirator type: filter A.

Observe the wear time limits according to GefStoffV in combination with the rules for using respiratory protection apparatus (BGR 190).

8.2.3 Environmental exposure controls

Emissions from ventilation or work process equipment should be checked to ensure they comply with the requirements of environmental protection legislation. In some cases, fume scrubbers, filters or engineering modifications to the process equipment will be necessary to reduce emissions to acceptable levels.
