Spontaneous Ignition Materials in Brethericks Book

Spontaneously ignitable materials 1K1 in Bretherick s book 1 1 are listed in Table 4.13. However, spontaneously ignitable materials defined here contain not only those which ignite spontaneously in contact with air at room temperature as defined in the Fire Service Law but also those which ignite spontaneously when stored in air for a long time. 

3 Test methods for water—reactive materials in the Fire Services Law(V) 

The purpose of the test is to determine the hazards of ignition and of the formation of combustible gas from solid or liquid materials when they contact water. 

If the test samples are stored in containers, after opening they must be quickly used in tests. If a solid sample is stored in a protective solution, the solution must be separated from the sample by use of filter paper 2 and the sample tested as quickly as possible. 

A(a) A filter paper support 8 is placed in the bottom of a 500 ml beaker. Pure water (ion exchanged water or distilled water) is added to the beaker up to the surface of the support. A piece of filter paper, 7 cm in diameter, is laid on the support, just touching the water so that the filter paper can be lifted. A small amount of sample (solid greater than 2mm diameter, liquid 4mm 1 ) is laid on the center of the filter paper to observe whether any evolved gas ignites spontaneously. If gas ignites spontaneously,
