4.7.METHODS OF INTERPRETATION OF SIGNS The interpretation of signs is a continual process in MA operations, as new signs will be continually observed from initial non-technical survey (NTS) to final completion. In order to make the best possible evidenced-informed decisions, it can help if staff consider the signs that they are presented with as: Facts / Assumptions / Interpretations.
FACTS
MA staff will identify a sign that can be used as direct or indirect evidence in relation to indicators such as VPs and current use of areas by the community. As already described, this is a conclusive sign.
ASSUMPTIONS
Inconclusive signs can be layered together along with IED indicators (see Section 1). Based on training and experience, MA staff will be able to make logical assumptions, up to and including using this as direct evidence.
ׁ HINT. Technical survey can be used to confirm an assumption prior to full clearance commencing.
INTERPRETATIONS
This is the logical thought process that MA staff can apply to a particular situation when signs have been observed.
ׁ HINT. Being able to link signs together is extremely important. For example, regularity, flattening and transference that are linked together could be graded as strong evidence of IED contamination, providing more confidence than any of these individual signs in isolation.
