Guidance on Safe Use
Administrative data
First-aid measures
-Inhalation: Remove from exposure to fresh air. Provide rest and warmth, keep in half-upright position. Get medical attention if any discomfort continues.
-Ingestion: Rinse mouth. Get medical aid.
-Skin contact: Remove contaminated clothing. Wash skin with plenty of soap and water.
-Eye contact: Flush eyes with plenty of water for at least 15 minutes, while lifting the upper and lower eyelids. Get medical aid if irriation occurs.
-Information for a doctor or other professionals giving first aid
Fire-fighting measures
-Suitable extinguishing media: Water, foam, powder, dry sand
-Extinguishing media which shall not be used for safety reasons: None.
-Special exposure hazards in a fire: Fire can generate toxic or caustic oxides.
-Special protective equipment for fire-fighters: Wear a self-contained breathing apparatus and full protective gear.
-Other instructions: Product in itself is not combustible
Accidental release measures
-Personal precautions: Prevent formation and spreading of dust. Wear personal protection. Instructions about protective equipment in Section 8.
-Environmental precautions: The heavy metals in product are dangerous for the environment. Do not release the product in soil, waterways or drains.
-Methods for cleaning up: Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting.
-Flush the area with plenty of water.
-Other instructions
Handling and storage
-Handling: Finely dispersed or grained particles from a dry product may form explosive mixtures in air: dust explosion possible. Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting. Keep away from heat, sparks and open flame. It is forbidden to eat, drink and smoke when handling this substance.
-Storage: Keep separate from strong oxidizers and strong acids.

Exposure controls / personal protection
Occupational exposure controls
Avoid breathing of dust. If possible, indoors use local exhaust extraction and efficient exhaust ventilation.
Keep away from food, drink and tobacco.
-Respiratory protection: In dusty conditions use respiratory protector (P2 filter respirator for harmful particles).
-Hand protection: Wear suitable protective gloves.
-Eye protection: Safety goggles.
-Skin protection: Use protective clothing.
-Environmental exposure controls: Do not release in soil, waterways or drains.
Stability and reactivity
-Conditions to avoid: Stable if the recommended conditions for use and storage are applied.
-Materials to avoid: Oxidizing agents and strong acids.
-Hazardous decomposition products: Thermal decomposition starts at 105-113 °C. Oxidation of elemental sulphur and fine-grained sulphides starts at 224 °C. On combustion and high temperatures, forms toxic and corrosive gases of sulfur oxides.
Disposal considerations
Hazardous waste.
EWC code 06 06 02* : wastes from the MFSU of sulphur chemicals, sulphur chemical processes and desulphurisation processes: wastes containing dangerous sulphides.
Disposal in accordance with local regulations.
