Key value for chemical safety assessment


Additional information

The lower and upper explosion limits of benzene vapour are 1.2 and 7.8%.

Justification for classification or non-classification

The flammability of liquids is determined on basis of their flashpoint (in combination with their boiling point), their ability to emit flammable gases upon contact with water and their pyrophoricity. The molecular structure of benzene does not contain groups that indicate potential reactivity with water or pyrophoric properties and handling of the substance indicates that this is the case. Benzene has a flash point of -11°C and a boiling point is 80.09°C and therefore meets the criteria of Category 2 for flammability (flash point <23 °C and boiling point of >35 °C) under the CLP Regulations.
