First Aid Measures
Emergency procedures for chemical exposure incidents
After inhalation: fresh air. Immediately call in physician. If breathing stops: immediately apply artificial respiration, if necessary also oxygen.
In case of skin contact: Take off immediately all contaminated clothing. Rinse skin with water/ shower. Call a physician immediately.
After eye contact: rinse out with plenty of water. Call in ophthalmologist. Remove contact lenses.
After swallowing: fresh air. Make victim drink ethanol (e.g. 1 drinking glass of a 40% alcoholic beverage). Call a doctor immediately (mention methanol ingestion). Only in exceptional cases, if no medical care is available within one hour, induce vomiting (only in fully conscious persons) and make victim drink ethanol again (approx. 0.3 ml of a 40% alcoholic beverage/kg body weight/hour).
Immediate Medical Attention
Call a physician immediately.
Firefighting Measures
Extinguishing media, specific hazards, and firefighter protection
Water, Foam, Carbon dioxide (CO2), Dry powder
For this substance/mixture no limitations of extinguishing agents are given.
Carbon oxides, Combustible. Pay attention to flashback. Vapors are heavier than air and may spread along floors. Development of hazardous combustion gases or vapours possible in the event of fire. Forms explosive mixtures with air at ambient temperatures.
Remove container from danger zone and cool with water.
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
Evacuate the danger area, observe emergency procedures, consult an expert.
Do not let product enter drains. Risk of explosion.
Take up carefully with liquid-absorbent material (e.g. Chemizorb®).
Materials: liquid-absorbent material (e.g. Chemizorb®)
