For personal protection see section 8.
6.2 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.
6.3 Methods and materials for containment and cleaning up
Sweep up and shovel. Contain spillage, and then collect with an electrically protected vacuum cleaner
or by wetbrushing
and place in container for disposal according to local regulations (see section 13). Keep in suitable,
closed
containers for disposal. Contain spillage, pick up with an electrically protected vacuum cleaner or by
wet-brushing
and transfer to a container for disposal according to local regulations (see section 13).
6.4 Reference to other sections
For disposal see section 13.
SECTION 7. HANDLING AND STORAGE
7.1 Precautions for safe handling
Avoid formation of dust and aerosols.Further processing of solid materials may result in the formation
of combustible
dusts. The potential for combustible dust formation should be taken into consideration before
additional processing
occurs.
Provide appropriate exhaust ventilation at places where dust is formed.Keep away from sources of
ignition - No
smoking.Take measures to prevent the build up of electrostatic charge.
For precautions see section 2.2.
7.2 Conditions for safe storage, including any incompatibilities
Keep container tightly closed in a dry and well-ventilated place.
Air-, heat-, and moisture-sensitive. Keep in a dry place. Handle and store under inert gas.
Storage class (TRGS 510): Flammable solid hazardous materials

8.2 Exposure controls
Appropriate engineering controls
Handle in accordance with good industrial hygiene and safety practice. Wash hands before breaks
and at the end of
workday.
Personal protective equipment
Eye/face protection
Safety glasses with side-shields conforming to EN166 Use equipment for eye protection tested and
approved
under appropriate government standards such as NIOSH (US) or EN 166(EU).
Skin protection
Handle with gloves. Gloves must be inspected prior to use. Use proper glove removal technique
(without
touching glove's outer surface) to avoid skin contact with this product. Dispose of contaminated gloves
after
use in accordance with applicable laws and good laboratory practices. Wash and dry hands.
Body Protection
Flame retardant antistatic protective clothing., The type of protective equipment must be selected
according to
the concentration and amount of the dangerous substance at the specific workplace.
Respiratory protection
Where risk assessment shows air-purifying respirators are appropriate use a full-face particle
respirator type
N100 (US) or type P3 (EN 143) respirator cartridges as a backup to engineering controls. If the
respirator is the
sole means of protection, use a full-face supplied air respirator. Use respirators and components
tested and
approved under appropriate government standards such as NIOSH (US) or CEN (EU).
Control of environmental exposure
Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the
environment must be avoided.
