6. ACCIDENTAL RELEASE MEASURES
6.1 Personal precautions, protective equipment and emergency procedures
Use personal protective equipment. Avoid dust formation. Do not breathe in vapour, mist or gas. Ensure adequate ventilation. Eliminate all ignition sources. Evacuate personnel to safe areas. Consequently, avoid breathing dust.
6.2 Environmental precautions
Prevent further spillage or leakage if it can be done safely. Do not allow the product to enter the sewer system.
6.3 Methods and materials for containment and cleaning
Sweep up or shovelling. Contain and then collect the spilt product using an earthed vacuum cleaner or by wet brushing. Place waste in a suitable container for disposal in accordance with local regulations (see Section 13). Store in a closed container for disposal. Consequently, contain the spilt material and collect it with an electrically safe vacuum cleaner.

7. HANDLING AND STORAGE
7.1 Precautions for safe handling
Avoid contact with skin and eyes. Prevent dust and aerosol formation; during further processing of solids, combustible dust may be produced. The possibility of combustible dust formation must be considered prior to further processing.
Ensure suitable extraction at locations where dust is present. Keep away from ignition sources – No smoking. Consequently, implement measures to avoid electrostatic charge accumulation.
7.2 Conditions for safe storage, including any incompatibilities
Store the container tightly closed in a dry and well-ventilated area.
Store in a dry place.
Storage class (TRGS 510): Flammable solid hazardous substance
7.3 Specific end uses
No specific end uses are foreseen other than those indicated in Section 1.2.

8. EXPOSURE CONTROLS/PERSONAL PROTECTIVE EQUIPMENT
Exposure controls
Use appropriate technical measures following good laboratory practice and safety procedure. Consequently, wash hands before breaks and at the end of the working day.
Personal protective equipment
Eye/face protection
Wear safety goggles with side protection according to EN166. Use devices that have been approved in accordance with applicable state standards such as NIOSH (USA) or EN 166 (EU).
Skin protection
Use gloves when handling. The gloves must be checked prior to use. When removing gloves, ensure that the outer surface is not touched, thereby preventing skin contact with the product. Dispose of contaminated gloves in accordance with applicable laws and good laboratory practice. Wash and dry hands thereafter.
Body protection
Wear impervious clothing, flame retardant and antistatic protective clothing; the type of protective equipment must be selected according to the concentration and quantity of the hazardous substance at the workplace.
Respiratory protection
If the risk assessment indicates that a respiratory protective device is necessary, use a full-face particulate respirator of type N100 (US) or type P3 (EN 143) as a supplement to technical controls. If the respirator is the only protective device, use one with an air supply. Consequently, use respiratory protective devices and components approved in accordance with applicable state standards such as NIOSH (USA) or CEN (EU).
Environmental exposure control
Take further measures to prevent leakages or spills if it can be done safely. Do not allow the product to enter the sewer system.
