6. Accidental Release Measures

Personal precautions, protective equipment and emergency procedures

Steps to be Taken in Case Material is Released or Spilled: Wear respiratory protection. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation

Environmental precautions

Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided Evacuate personnel to safe areas. Avoid breathing dust. Methods and materials for containment and cleaning up: Pick up and arrange disposal without creating dust. Sweep up and shovel. Keep in suitable, closed containers for disposal. Environmental precautions: Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided.

Methods and materials for containment and clean up

Must not be disposed together with household garbage. Do not allow product to reach sewage system. Dispose of waste according to Federal, State and Local Regulations.

7. Handling and Storage

Precautions for safe handling

Avoid contact with skin and eyes. Avoid breathing vapours, mist or gas. Wear respiratory protection. Avoid formation of dust and aerosols. Provide appropriate exhaust ventilation at places where dust is formed.

Conditions for safe storage

• Keep container tightly closed in a dry and well-ventilated place. Store in metal can supplied with product.
• Storage temperature: Room temperature.
• Storage Pressure: NA

8. Exposure Controls / Personal Protection

Exposure Standards

Engineering controls

• General protective and hygienic measures:
• 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.

Personal protective equipment

Eye and face protection

Face shield and safety glasses Use equipment for eye protection tested and approved under appropriate government standards such as NIOSH (US) or EN 166(EU).

Skin protection

Full contact Material: Nitrile rubber, Minimum layer thickness: 0.11 mm, Break through time: 480 min Material tested: Dermatril® nitrile gloves

Body protection

• Protection of Hands: 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 of the penetration times, rates of diffusion and the degradation. · Material of gloves The selection of the suitable gloves does not only depend on the material, but also on further marks of quality and varies from manufacturer to manufacturer.

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.
