Properties: The highly flammable, colorless liquid has a characteristic odor. The steam mixes easily with the air. Mixtures of the substance and air are explosive. Plastics are attacked. A reaction occurs with strong bases, strong oxidizing agents and strong acids. There is always an acute risk of fire and explosion.

Symptoms: The substance can be inhaled or ingested and is irritating to the eyes and the respiratory tract. Toxic contamination of the air quickly occurs at a temperature of 20 ° C. There is reddening of the eyes. The skin becomes dehydrated. After inhalation, the patient has a sore throat and a cough. Exposure above the occupational exposure limit can lead to impaired consciousness or even unconsciousness. After repeated or prolonged contact with the liquid, the skin is degreased.

Activities: Rescue the patient from the contaminated environment with self-contained breathing apparatus. Each patient receives at least four liters of oxygen per minute. Remove contaminated clothing and flush the affected skin with plenty of water. If the eye is affected, it must be anesthetized and carefully rinsed. All further measures are symptomatic. Clinical monitoring must always be carried out.

Precautions: Open flames and sparks are to be avoided. It is forbidden to smoke. The skin and eyes must be protected with suitable protective materials. For personal protection, the breathing apparatus must have at least one A / P2 filter.
