Photographs should be taken of the failed piece
of equipment including the samples to be removed and their surroundings. These
should show the relationship of the questioned area to the remainder of the
piece of equipment. Additional photos should be taken of the samples after
removal to fully identify them. If more than one sample is to be taken, proper
designation of the sample and its location relative to the piece of equipment
should be noted. The dimensions of the sample, the date the failure occurred,
and the date of the photographs should be noted. Consider the use of video
recording if complex disassembly is required.
