First Aid Measures
Emergency procedures for chemical exposure incidents
Remove victim into fresh air. In case of respiratory problems, consult a doctor/medical service.
Symptoms: AFTER INHALATION OF DUST: Coughing.
If possible, wipe up/dry remove chemical. Then rinse/shower immediately with (lukewarm) water.
Symptoms: No effects known.
Rinse immediately with (lukewarm) water. Remove contact lenses, if present and easy to do. Continue rinsing. If irritation persists, consult a doctor/medical service.
Symptoms: No effects known.
Rinse mouth with water. If you feel unwell, consult a doctor/medical service. Do not wait for symptoms to occur to consult Poison Center.
Symptoms: AFTER INGESTION OF HIGH QUANTITIES: Nausea. Vomiting. Diarrhoea.
Firefighting Measures
Extinguishing media, specific hazards, and firefighter protection
Adapt extinguishing media to the environment for surrounding fires.
DIRECT FIRE HAZARD: Non combustible. INDIRECT FIRE HAZARD: Reactions involving a fire hazard: see "Reactivity Hazard". DIRECT EXPLOSION HAZARD: No direct explosion hazard. INDIRECT EXPLOSION HAZARD: Reactions with explosion hazards: see "Reactivity Hazard".
Dilute toxic gases with water spray. Take account of toxic/corrosive precipitation water.
Firefighter Protection
Heat/fire exposure: self-contained breathing apparatus (EN 136 + EN 137).
Accidental Release Measures
Spill cleanup procedures, containment, and environmental protection
Mark the danger area. Prevent dust cloud formation, e.g. by wetting. No naked flames. Keep containers closed. Wash contaminated clothes. In case of hazardous reactions: keep upwind. In case of reactivity hazard: consider evacuation.
No additional information available
Stop dust cloud by humidifying. Stop dust cloud by covering with sand/earth. Scoop solid spill into closing containers. Clean contaminated surfaces with an excess of water. Wash clothing and equipment after handling.
Materials: sand/earth
