Description of key information

Values for LEL: 2, 2.0, 2.2%. and 2.1 to 2.5%
Values for UEL: 11.5% consistently reported in the range 10.2 to 12%

Key value for chemical safety assessment

highly flammable

Additional information

Based on consideration of the structure and experience in handling and use of this substance, ethyl acetate is expected to be non-pyrophoric and non-flammable on contact with water.

Justification for classification or non-classification

A number of sources report values for the explosive limits of ethyl acetate. A small range of values are available for the lower explosive limit. A figure of 2.2% is consistently reported, including from a reliable source. This represents approximately the mid point of cited values. The figure of 11.5% is consistenly reported apart from a range of values with 11.5% as a maximum, which is cited in a handbook that reports data from manufacturers. A figure of 11.5% is used as the key value for the UEL based on a conservative approach and the fact that this is cited in a reliable source.
