First-aid measures

-General informations:
Move victim out of danger zone. Position and transport victim on their side. In case of respiratory distress, bring into semi-upright, seated position. Remove contaminated clothing immediatley and dispose off safely. Put victim at rest, cover with a blanket and keep warm. Do not leave victim unattended. In case of accident or if you feel unwell, seek medical advice immediately (show safety data sheet if possible).
Seek medical advice.
- In case of inhalation: Provide fresh air. In case of breathing difficulties administer oxygen.
- In case of skin contact: Take off immediately all contaminated clothing. After contact with skin, wash immediately with: Water. Subsequently wash again with: Water and soap.
- In case of eye contact: If product gets into the eye, keep eyelid open and rinse immediately with large quantities of water, for at least 5 minutes. Subsequently consult an ophthalmologist. Protect the eye that is not injured.
- In case of ingestion: Rinse mouth immediately and drink large quantities of water. Do not induce vomiting.
- Self-protection of the first aider: First aid assistant: Pay attention to self-protection!
- Information to physician:
*) Routes of exposure: The substance can be absorbed into the body by inhalation of its aerosol and by ingestion.
*) Hazards:
Effects of short-term exposure: The substance is irritating to the eyes, the skin and the respiratory tract.
Effects of long-term or repeated exposure: -
Notes: Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed.
*) Symptoms:
In case of inhalation: Cough. Sore throat. Shortness of breath.
In case of skin contact: Redness.
In case of eye contact: Redness. Pain. Temporary loss of vision.
In case of ingestion: Abdominal pain. Diarrhoea. Nausea. Vomiting.
*) Treatment: First Aid, decontamination, treatment of symptoms.

Fire-fighting measures

- Suitable extinguishing media: Water spray jet. Water mist. Foam. Carbon dioxide (CO2). Extinguishing powder.
- Extinguishing media which must not be used for safety reasons: Full water jet.
- Special exposure hazards arising from the substance or preparation itself, combustion products, resulting gases: In case of fire may be liberated:
Sulphur dioxide (SO2). Sulphur trioxide.
- Special protective equipment for fire-fighters: In case of fire: Wear self-contained breathing apparatus.
- Additional information:
Intervention Actions-General: Keep upwind.
Intervention Actions-Fire (involving the substance): Heating of container(s) will cause pressure rise with risk of bursting and subsequent explosion. Gives off toxic and irritant fumes when heated or burning. The vapour may be invisible and is heavier than air. It spreads along the ground and may enter sewers and basements. Keep container(s) cool with water. Extinguish with water fog (spray). Do not use water jet to extinguish. Use water spray to knock down fire fumes if possible. Avoid unnecessary run-off of extinguishing media which may cause pollution.

Accidental release measures

- Personal precautions (spillage): Wear personal protection equipment.
- Environmental precautions: Stop leaks if possible. Contain spillage by any means available. Cover drains. Do not allow to enter into soil/subsoil. Do not empty into drains or the aquatic environment.
- Methods for cleaning up: Refer to Additional information
- Additional information :Sweep spilled substance into containers. Carefully collect remainder, then remove to safe place. Personal protection: P2 filter respirator for inert particles. Do NOT let this chemical enter the environment.

Handling and storage

- Handling
*) Advices on safe handling:
Protective measures: Wear personal protection equipment. Refer to chapter Exposure Controls/ personal protection. Do not eat, drink, smoke or sneeze at the workplace.
Dangerous areas must be delimited and marked with appropriate warning and safety signs. In the immediate working surroundings there must be: Emergency spray installed. provide eye wash and label its location conspicuously. provide sufficient washing facilities. Fill only into labelled container. Instruction on the hazards and the protective measures using instruction manual are required with signature. Working areas must be arranged in such a manner that they can be cleaned at all times.
*) Technical measures: Measures to prevent aerosol and dust generation. It is recommende to design all work processes always so that the following is excluded: Inhalation. Skin contact. Eye contact. If handled uncovered, arrangements with local exhaust ventilation should be used if possible.
Measures required to protect the environment No special environmental protection measures are necessary.
*) Specific requirements or handling rules: The floor should be leak tight, jointless and not absorbent.
*) Precautions against fire and explosion: Usual measures for fire prevention.
- Storage:
*) Technical measures and storage conditions:
Keep container tightly closed. Keep/Store only in original container.
Protect against: Humidity. UV-radiation/sunlight.
*) Hints on storage assembly:
Keep away from food, drink and animal feedingstuffs.
*) Further information on storage conditions:
Storage class: 10-13 sonstige Flüssigkeiten und Feststoffe
Storage temperature : 10 °C – 30 °C
Relative air humidity: 10 – 55 %
Maximum period of storage: 2 Jahre / years / Años / ans / anni / jaren

Personal protection equipment

Respiratory protection: Respiratory protection required in case of: Handling larger quantities. In the case of the formation of dust.
Suitable respiratory protective equipment: Particle filter device (DIN EN 143).
Type of mask: Half-face mask (DIN EN 140).
Filtering device: P2 or P3
Hand protection: Use protective gloves. The glove material must be sufficiently impermeable and resistant to the substance. Check the tightness before wear. Gloves should be well cleaned before being removed, then stored in a well ventilated location. Pay attention to skin care. Textile or leather gloves are completely unsuitable.
The following information is valid for aqueous, saturated solutions of the substance.
Suitable materials for gloves are (brakthrough time>=8 hours):
NR (Natural rubber (Caoutchouc), Natural latex) - NR (0,5 mm); CR (polychloroprenes, Chloroprene
rubber) - CR (0,5 mm); NBR (Nitrile rubber)- NBR (0,35 mm); Butyl rubber - Butyl (0,5 mm); FKM
(fluororubber) - FKM (0,4 mm); PVC (Polyvinyl chloride)- PVC (0,5 mm);

The times listed are suggested by measurements taken at 22 degree C and constant contact. Temperatures raised by warmed substances, body heat, etc. and a weakening of the effective layer thickness caused by expansion can lead to a significantly shorter breakthrough time. In case of doubt contact the gloves' manufacturer. A 1.5-times increase / decrease in the layer thickness doubles / halves the breakthrough time. This data only applies to the pure substance. Transferred to mixtures of substances, these figures should only be taken as an aid to orientation.

Eye protection
Suitable eye protection: Tightly sealed safety glasses.
Remark: -

Protective clothing
Suitable protection of the body: Chemical resistant safety shoes. Protective
clothing: DIN EN 13034
Required properties: -

General health and safety measures
When using do not eat, drink, smoke, sneeze. Wash hands and face before breaks and after work and take a shower if necessary. Draw up skin protection programme. Used working clothes must not be worn outside the working area. Separate storage of work clothes. Immediately remove any contaminated clothing, shoes or stockings. In the immediate working surroundings there must be: Emergency shower installed. Make available sufficient washing facilities. Provide eye shower and label its location conspicuously. Set out skin protection guidelines. Only wear fitting, comfortable and clean protective clothing.
*) Environmental exposure controls
See section Handling and Storage. No additional measures necessary.
