Section 4 – First Aid Measures
Inhalation: If overcome by high dust concentrations, remove to a ventilated area.
Eye Contact: Flush eyes thoroughly for several minutes taking care to rinse under eyelids. Do not scrub. Abrasion may cause
irritation. If discomfort continues, continue to wash with water. If irritation persists, consult a physician.
Skin Contact: Wash skin thoroughly with soap and water. Consult a physician if irritation persists.

Special hazards arising from the chemical: None.
Hazardous Combustion Products: None.
Fire-Fighting Instructions: Use self-contained breathing apparatus. Fire residues and contaminated firefighting water must be
disposed of following local regulations.
Section 6 – Accidental Release Measures
Personal precautions, protective equipment, and emergency procedures: Avoid dust formation. In case of inadequate
ventilation wear respiratory protection.
Environmental precautions: Do not discharge into drains/surface water/groundwater.
Methods and materials for containment and cleaning up: Sweep up and dispose of per local regulations.
Reference to other sections: See Sections 8 & 13.

Section 7 – Handling and Storage
Precautions for safe handling: Avoid generating dust during handling. Provide vacuuming if dust is raised. Wash hands
before breaks and after work. Use barrier skin cream.
Conditions for safe storage, including any incompatibilities: Keep container tightly closed. Store in a dry place. Do not
store with food.
Section 8 – Exposure Controls / Personal Protection
Engineering Controls:
Ventilation: Provide general or local exhaust ventilation systems to maintain airborne concentrations below OSHA PELs
(Sec. 2). Local exhaust ventilation is preferred because it prevents contaminant dispersion into the work area by controlling it at
its source.
Administrative Controls:
Eye Protection: Safety glasses.
Hand Protection: Protective gloves are recommended.
Glove material: Nitrile rubber
Layer thickness: 0.11 mm
Breakthrough time: >480 min
Skin Protection: Protective clothing.
Other: Avoid contact with eyes and skin.
Do not inhale the dust.
PPE should be selected specifically for the workplace, depending on the concentration and quantity handled.
Respiratory Protection: In the event of high concentrations use a respirator with a P1 filter for short-term use.
Contaminated Equipment: Separate contaminated work clothes from street clothes. Launder before reuse. Remove this
material from your shoes and clean personal protective equipment.
Comments: Never eat, drink, or smoke in work areas. Practice good personal hygiene after using this material, especially before
eating, drinking, smoking, using the toilet, or applying cosmetics.
