Safety Information:

This chemical is highly toxic and is rapidly absorbed through the skin. It is a flammable liquid and forms an explosive mixture with air. This alcohol is a skin irritant and a strong eye irritant and is toxic in any way.

In the presence of pollutants, especially at high temperatures, steam combustion and explosive reactions can occur. Heating the undiluted form with bases or strong acids should be avoided. Weak acids are used to stabilize propargyl alcohol before distillation.

First-aid measures:

• Skin Contact: Immediately flush skin with water.
• Inhalation: move the person to the fresh air.
• Eye Contact: Rinse eyes with water for several minutes.
• Ingestion: Do not induce vomiting. Get medical aid immediately. Call a poison control center.
