Description of key information

1-bromopropane is a liquid at room temperature and so conducting a flammability study for solids or gasses would not be feasible.
In addition to this, experience of use determines that neither a pyrophoric properties study nor a flammability in contact with water study need to be carried out as there is no evidence of 1-bromopropane either spontaneously igniting in air at room temperature or exhibiting flammable properties in contact with water.

Key value for chemical safety assessment

highly flammable

Additional information

Justification for classification or non-classification

According to section 2.2.4 of Directive 67/548/EEC and the evidence presented in this dossier, the substance does not meet the quantitative criteria for classification as highly flammable (R11). However, n-propyl bromide is officially classified as F; R11 on Annex I of Directive 67/548/EEC and as a Flammable Liquid Category 2 on Annex VI of the EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation (EC) No. 1272/2008.
