Description of key information

The lower and upper explosion limits of m xylene are 1.1-7%, o xylene are 0.9-6.7%, p xylene are 1.1-7%, and ethylbenzene are 0.8 - 6.7%

Key value for chemical safety assessment


Additional information

The CRC Handbook (Lide, 2008) is a peer reviewed handbook and so can be considered reliable and suitable for use as the key study for this endpoint.

Justification for classification or non-classification

The flammability of liquids is determined on the 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 these streams do not contain any groups that indicate potential reactivity with water or pyrophoric properties and handling of the substance indicates that this is the case. The lowest flashpoint indicates that the members of this category would be considered as Category 2 flammable liquid with the hazard statement 'highly flammable liquid and vapour' under the CLP Regulation.
