PRINCIPLE 2 Building clearance should be executed in accordance with an approved clearance plan. This plan should include control measures to account for the threat assessment being updated as more evidence on the EO contamination is obtained. This principle is applicable to searching for IEDs in any environment. A clearance plan that outlines how different activities (e.g. non-technical survey, search, improvised explosive device disposal (IEDD) and information management) will be used together, can help achieve “all reasonable effort”. It also enables controls to be specified in how to deal with changes, such as alterations in search procedures based on new evidence. The clearance plan will likely combine set procedures, detailed in an MA operator’s operational SOPs, with different combinations selected based on the threat assessment.
