Additional information

Data from the CRC handbook (Lide 2008) were available for propane, butane and isobutane. The information is taken from a reliable peer reviewed handbook and so can be considered reliable and suitable for use for this endpoint.

The flash point of propane is -104°C, butane is -60°C and isobutane is -87°C. The data available for these substances can be read across to other members of the category. The mean for the category is -84°C and this has been used to complete the 'key value for chemical safety assessment'.
