Description of first aid measures
General adviceMost important symptoms and effects, both acute and delayed
Indication of any immediate medical attention and special treatment needed
Extinguishing media
Unsuitable extinguishing mediaSpecial hazards arising from the substance or mixture
Carbon oxides, Nitrogen oxides (NOx)
Advice for firefighters
Stay in danger area only with self-contained breathing apparatus. Prevent skin contact by keeping a safe distance or by wearing suitable protective clothing.
Further information

NFPA 704
| HEALTH | 1 | Exposure would cause irritation with only minor residual injury (e.g. acetone, sodium bromate, potassium chloride) | |
| FIRE | 2 | Must be moderately heated or exposed to relatively high ambient temperature before ignition can occur and multiple finely divided suspended solids that do not require heating before ignition can occur. Flash point between 37.8 and 93.3 °C (100 and 200 °F). (e.g. diesel fuel, sulfur) | |
| REACT | 0 | Normally stable, even under fire exposure conditions, and is not reactive with water (e.g. helium,N2) | |
| SPEC. HAZ. |
Personal precautions, protective equipment and emergency procedures
Advice for non-emergency personnel: Do not breathe vapors, aerosols. Avoid substance contact. Ensure adequate ventilation. Keep away from heat and sources of ignition.
Evacuate the danger area, observe emergency procedures, consult an expert. Advice for emergency responders: Protective equipment see section 8.
For personal protection see section 8.
Environmental precautions
