First Aid Measures
Emergency procedures for chemical exposure incidents
fresh air.
wash off with plenty of water. Remove contaminated clothing.
rinse out with plenty of water. Immediately call in ophthalmologist.
Symptoms: Risk of blindness!
immediately make victim drink water (two glasses at most). Consult a physician.
Immediate Medical Attention
Immediately call in ophthalmologist. Consult a physician.
Firefighting Measures
Extinguishing media, specific hazards, and firefighter protection
Use extinguishing measures that are appropriate to local circumstances and the surrounding environment.
Foam, Water
Not combustible. Ambient fire may liberate hazardous vapours. Fire may cause evolution of: Sulphur oxides. May not get in touch with: Water. The product reacts with water and generates heat.
Suppress (knock down) gases/vapours/mists with a water spray jet.
Firefighter Protection
Stay in danger area only with self-contained breathing apparatus. Prevent skin contact by keeping a safe distance or by wearing suitable protective clothing.
Accidental Release Measures
Spill cleanup procedures, containment, and environmental protection
Avoid substance contact. Avoid inhalation of dusts. Ensure adequate ventilation. Evacuate the danger area, observe emergency procedures, consult an expert.
Do not empty into drains.
Take up dry. Dispose of properly. Clean up affected area.
