4. First Aid Measures

Ingestion

Immediately call a doctor. Drink copious amounts of water and provide fresh air. Immediately call a doctor.

Inhalation

Supply fresh air. If required, provide artificial respiration. Keep patient warm. Consult doctor if symptoms persist. In case of unconsciousness place patient stably in side position for transportation.

Skin Contact

Immediately wash with water and soap and rinse thoroughly.

Eye Contact

Rinse opened eye for several minutes under running water. Then consult a doctor.

Other Information

Immediately remove any clothing soiled by the product. Symptoms of poisoning may even occur after several hours; therefore medical observation for at least 48 hours after the accident.

6. Accidental Release Measures

Personal precautions, protective equipment and emergency procedures

Wear protective equipment. Keep unprotected persons away.

Environmental precautions

• Dilute with plenty of water.
• Do not allow to enter sewers/ surface or ground water.

Methods and materials for containment and clean up

• Absorb with liquid-binding material (sand, diatomite, acid binders, universal binders, sawdust).
• Use neutralizing agent.
• Dispose contaminated material as waste according to item 13.
• Ensure adequate ventilation.

7. Handling and Storage

Precautions for safe handling

• Ensure good ventilation/exhaustion at the workplace.
• Prevent formation of aerosols.
• Keep ignition sources away - Do not smoke.
• Protect from heat.
• Protect against electrostatic charges.

Conditions for safe storage

• Keep receptacle tightly sealed.
• Store in cool, dry conditions in well sealed receptacles.
• Protect from heat and direct sunlight.

8. Exposure Controls / Personal Protection

Exposure Standards

Engineering controls

• Keep away from foodstuffs, beverages and feed.
• Immediately remove all soiled and contaminated clothing.
• Wash hands before breaks and at the end of work.
• Avoid contact with the eyes and skin.

Personal protective equipment

Eye and face protection

Tightly sealed goggles. Avoid contact with the eyes.

Skin protection

Wear protective gloves. The glove material has to be impermeable and resistant to the product/ the substance/ the preparation. Due to missing tests no recommendation to the glove material can be given for the product/ the preparation/ the chemical mixture. Selection of the glove material on consideration times, rates of diffusion and the degradation. The exact break through time has to be found out by the manufacturer of the protective gloves and has to be observed.

Body protection

Avoid contact with the skin. Wear appropriate clothing. Immediately remove all soiled and contaminated clothing.

Respiratory protection

In case of brief exposure or low pollution use respiratory filter device. In case of intensive or longer exposure use respiratory protective device that is independent of circulating air.
