Guidance on Safe Use

First-aid measures

Description of first aid measures

Inhalation: Fresh air, rest, half upright position. Get medical advice / attention if you feel unwell.

Skin contact: Remove contaminated clothes, rinse skin with water or shower. If skin irritation occurs: get medical advice / attention.

Eye contact: First rinse with plenty of water (remove lenses if possible). If eye irritation persists: get medical advice / attention.

Ingestion: Rinse mouth. Get medical advice / attention if you feel unwell.

Most important symptoms and effects, both acute and delayed

Acute symptoms and effects from exposure: Redness and pain in the eyes. Redness of the skin.

Delayed symptoms and effects from exposure : Causes damage to lungs [obliterative bronchiolitis (OB)] through prolonged or repeated exposure by inhalation.

Symptoms of lung disease may include (but is not limited to) persistent dry cough, wheezing, shortness of breath upon exertion and fixed airways obstruction on spirometry.

Indication of any immediate medical attention and special treatment needed

Information on medical attendance: Not known.

Special means to provide treatment at the workplace: Not known.

Fire-fighting measures

Firefighting measures

Extinguishing media:

Suitable extinguishing media: Powder, water spray, alcohol-resistant foam, carbon dioxide.

Unsuitable extinguishing media: Water jet, alcohol unstable foam.

Special hazards arising from the substance or mixture

Hazardous combustion products: May produce toxic fumes of carbon monoxide if burning.

Additional hazards: Brief exposure through inhalation to high concentrations may cause lung disease. The vapour is heavier than air, spreads along the ground and distant ignition is possible. Run off to sewer may cause fire or explosion hazard. Containers may explode in heat of fire.

Advice for fire-fighters

Protective actions: In case of fire: keep containers cool by spraying with water. Retain contaminated extinguishing water; do not allow entering into the sewage system. In the case of larger fires: Cordon affected area.

Special protective equipment: Self-contained respiratory protective device, full protective suit.

Accidental release measures

Personal precautions, protective equipment and emergency procedures

Information for non-emergency personnel

Vapour may form an explosive mixture with air. Therefore, eliminate all sources of ignition.

Use personal protective equipment to avoid any contamination of skin and eyes. Do not breathe vapours.

Indoor spills: Assure sufficient ventilation.

Outdoor spills: Stay up wind and keep out of low areas where vapour may accumulate and ignite.

Stop leak if this can be achieved without risk.

In the case of large quantities: Consider need for evacuation.

Information for emergency responders

Environmental precautions

Try to prevent the material from entering drains, water courses or soil.

Advise authorities if spillage has entered water course or sewer or has contaminated soil.

Methods and material for containment and cleaning up

Small spills: Allow to evaporate if it is safe to do so or contain and absorb using earth, sand or other inert material then transfer into suitable containers for recovery or disposal.

Large spills: Ventilate contaminated area thoroughly. Cover drains. Dike or dam in and vacuum up carefully. Wash away remainder with water.

Handling and storage

Handling and storage

Precautions for safe handling

Recommendations for safe handling

Use only in well ventilated areas and in a closed system.

Keep away from heat, sparks, open flames, hot surfaces and do not smoke.

Do not breathe vapours. Avoid contact with eyes, skin and clothing.

Take measures to prevent electrostatic charges, e.g. grounding when transferring/ filing.

Containers have to be properly labelled.

Advice on general occupational hygiene

Do not eat, drink and smoke in work areas.

Use fatty skin care products after repeated contact and washing hands.

Conditions for safe storage, including any incompatibilities

Precautions for safe storage and protection against incompatible substances

Store in a well-ventilated place. Keep containers tightly closed.

Keep away from oxidants reducing agents, strong bases and strong acids.

Store away from sources of heat or ignition. Storage tanks should have equipotential electrical bonding and be earthed.

Beware of formation of explosive vapour-air mixtures in empty, uncleaned containers.

Protection against ambient influences

Protect against heat and solar radiation. Recommended storage temperature: 20 ºC.

The substance affects many synthetic materials; store only in original packing.

Suited materials for containers are: diacetyl resistant plastics, mild steel, stainless steel.

Maintenance of the integrity of the substance

Not required.

Specific end use(s): If used in food: comply with food safety regulation (HACCP).

Control parameters

Limit values (8 hours (TWA), Short term (15 min.)): not determined

DNEL / DMEL values: No data available.

PNEC values: No data available.

Stability and reactivity

Reactivity

Exothermic, partially violent reactions with oxidising agents, reducing agents, strong acids and bases possible.

Chemical stability

Stable at usual storage conditions. Decomposes slowly on exposure to light. No stabilizers required.

Possibility of hazardous reactions

Excessive heat generation or splashes of hazardous substances with oxidising agents, reducing agents, strong bases and acids. Contact with strong oxidizers may cause fire and explosions. In case of strong heat: polymerization.

Conditions to avoid

Storage temperatures > 40 °C should be avoided (increase in pressure, deformation of the containers) and direct sunlight.

Avoid static discharge and sources of ignition (open flames, warm surfaces, sparks).

Incompatible materials

Strong oxidising agents and reducing agents, strong acids and bases.

The substance affects some plastics.

Hazardous decomposition products

Does not decompose when used for intended uses.

Disposal considerations

Waste treatment methods

Product disposal

Recycling by distillation.

Removal to an authorized waste incinerator for solvents or as chemical waste in accordance with local regulations. Do not discharge wastewater into sewer.

Packaging disposal

Uncleaned empty package have to be treated like the content. The labelling of uncleaned containers must not be removed.
