First Aid Measures

Emergency procedures for chemical exposure incidents

Inhalation

After inhalation: fresh air. Immediately call in physician. If breathing stops: immediately apply artificial respiration, if necessary also oxygen.

Skin contact

In case of skin contact: Take off immediately all contaminated clothing. Rinse skin with water/ shower. Call a physician immediately.

Eye contact

After eye contact: rinse out with plenty of water. Call in ophthalmologist. Remove contact lenses.

Ingestion

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

Suitable media

Water, Foam, Carbon dioxide (CO2), Dry powder

Unsuitable media

For this substance/mixture no limitations of extinguishing agents are given.

Specific hazards

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.

Instructions

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.

06

Accidental Release Measures
