Make any required cuts well away from the failure to avoid mechanical deformation and other damage that can obscure evidence at the failure site.

Whenever possible make cuts with a toothed saw and no lubricant.

If flame cutting or abrasive cutting without lubricants must be done, make cuts far enough away from the failure site to avoid heating the material at the failure. Allow at least 8 cm for abrasive cuts and 10 cm for flame cuts, but actual distance depends on the size of the section.
