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
Suitable extinguishing mediaSpecial hazards arising from the substance or mixture
Carbon oxides Combustible.
Vapors are heavier than air and may spread along floors. Forms explosive mixtures with air at elevated temperatures.
Development of hazardous combustion gases or vapours possible in the event of fire.
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
Remove container from danger zone and cool with water. Prevent fire extinguishing water from contaminating surface water or the ground water system.
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 | 1 | Normally stable, but can become unstable at elevated temperatures and pressures (e.g. propene) | |
| 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. For personal protection see section 8.
Environmental precautions
Do not let product enter drains. Risk of explosion.
Methods and materials for containment and cleaning up
Cover drains. Collect, bind, and pump off spills. Observe possible material restrictions (see sections 7 and 10). Take up carefully with liquid-absorbent material (e.g.
Chemizorb?). Dispose of properly. Clean up affected area.
Reference to other sections
For disposal see section 13.
Precautions for safe handling
Advice on safe handling
Work under hood. Do not inhale substance/mixture. Avoid generation of vapours/aerosols.
Advice on protection against fire and explosion
Keep away from open flames, hot surfaces and sources of ignition.Take precautionary measures against static discharge.
Hygiene measures
Immediately change contaminated clothing. Apply preventive skin protection. Wash hands and face after working with substance.
For precautions see section 2.2.
Conditions for safe storage, including any incompatibilities
Storage conditions
Keep container tightly closed in a dry and well-ventilated place. Keep away from heat and sources of ignition. Keep locked up or in an area accessible only to qualified or authorized persons.
Test for peroxide formation periodically and before distillation.
Specific end use(s)
Apart from the uses mentioned in section 1.2 no other specific uses are stipulated
