7. Handling and Storage

Precautions for safe handling

• Ensure good ventilation/exhaustion at the workplace.
• Open and handle receptacle with care.
• Prevent formation of aerosols.
• Keep ignition sources away - Do not smoke.
• Protect from heat.
• Protect against electrostatic charges.
• Keep respiratory protective device available.

Conditions for safe storage

• Store in a cool location.
• Keep container 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.
• Store protective clothing separately.
• Avoid contact with the eyes.
• Avoid contact with the eyes and skin.

Personal protective equipment

Eye and face protection

Tightly sealed goggles.

Skin protection

Wear protective gloves. The glove material has to be impermeable and resistant to the product/the substance/the preparation. Selection of the glove material on consideration of the penetration 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

Wear protective clothing.

Respiratory protection

In case of brief exposure or low pollution use respiratory filter device. In case of intensive or longer exposure use self-contained respiratory protective device.

No further relevant information available.

Other adverse effects

• Water hazard class 3: extremely hazardous for water.
• Do not allow product to reach ground water, water course or sewage system, even in small quantities.
• Must not reach sewage water or drainage ditch undiluted or unneutralised.
• Danger to drinking water if even extremely small quantities leak into the ground.
• Rinse off of bigger amounts into drains or the aquatic environment may lead to decreased pH-values. A low pH-value harms aquatic organisms. In the dilution of the use-level the pH-value is considerably increased, so that after the use of the product the aqueous waste, emptied into drains, is only low water-dangerous.
