Guidance on Safe Use
Administrative data
First-aid measures
- Inhalation: Immediately relocate to a fresh air environment. Rinse mouth with water. If not breathing, give artificial respiration. If breathing becomes difficult, give oxygen and seek medical attention.
- Skin Contact: Wash with soap and copious amounts of water. If irritation persists, seek medical attention.
- Eye Contact: Immediately flush eyes with copious amounts of water for at least 15 minutes. Assure adequate flushing by separating eyelids with fingers. If contact lenses are being worn, remove lenses and continue rinsing. Seek medical attention.
- Ingestion: Rinse mouth with water and seek medical attention.
Fire-fighting measures
- Flash point (method used): Not known
- Flammable limits: Not known
- Extinguishing media: Water spray, carbon dioxide, dry chemical powder/foam
- Special fire fighting procedures: Minimize dust formation
- Unusual fire and explosion hazards: Fine dust dispersed in air in sufficient concentrations, and in the presence of an ignition source is a potential dust explosion hazard. Upon combustion will result in carbon monoxide, carbon dioxide and nitrogen oxide being released.
Accidental release measures
- Personal precautions, protective equipment: Use personal protection
- Precautions for the environment: Do not discharge into sewer, river, underground water, etc.
- Recovery, neutralization: Make spills wet to prevent the generation of dust and then, sweep up into a closed container.
- Method for containment and clean-up: After recovering, wash away spilled area with plenty of water.
Handling and storage
- Handling: Follow good industrial practice in housekeeping and personal hygiene. Wear personal protective equipment as outlined in section 8.
- Storage: Store in closed containers in a dry area. Avoid humidity, sunlight and high temperature.
