First Aid Measures

Emergency procedures for chemical exposure incidents

Inhalation

After inhalation: fresh air. Call in physician.

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. Immediately call in ophthalmologist. Remove contact lenses.

Ingestion

If swallowed: give water to drink (two glasses at most). Seek medical advice immediately. In exceptional cases only, if medical care is not available within one hour, induce vomiting (only in persons who are wide awake and fully conscious), administer activated charcoal (20 - 40 g in a 10% slurry) and consult a doctor as quickly as possible. Do not attempt to neutralise.

Immediate Medical Attention

Call in physician. Call a physician immediately. Immediately call in ophthalmologist. Seek medical advice immediately. consult a doctor as quickly as possible.

Stability and Reactivity

Chemical stability, hazardous reactions, and incompatible materials

Stability

The product is chemically stable under standard ambient conditions (room temperature).

Reactivity

Forms explosive mixtures with air on intense heating. A range from approx. 15 Kelvin below the flash point is to be rated as critical. The following applies in general to flammable organic substances and mixtures: in correspondingly fine distribution, when whirled up a dust explosion potential may generally be assumed.

Hazardous reactions

Violent reactions possible with: Strong oxidizing agents, Nitric acid, fuming sulfuric acid, Aluminium

Avoid

Strong heating.

Incompatible

No data available

Decomposition

In the event of fire: see section 5
