MODULE 1 50 A DEMONSTRATION OF CRITICAL SEPARATION

MODULE # 1. 50: A DEMONSTRATION OF CRITICAL SEPARATION track: Ground Search level: 1 module #: 5 module: A Demonstration of Critical Separation All Ground Search Level 0 pre–requisites: Modules plus 1. 0, 1. 1, 1. 2, 1. 3 and 1. 4 International SAR Alliance Training Module 1

MODULE # 1. 50: A DEMONSTRATION OF CRITICAL SEPARATION illustrate the concept This module can be used to illustrate the concept of Critical Separation. It is a simple demonstration of : u The question of how many searchers need to see the object u To show far apart searchers can be and still be able to see a specified object u How we can make best use of search resources by spacing them out across a wide area It can be used alongside modules 1. 4 and 1. 5 but not as a substitute for them. International SAR Alliance Training Module 2

MODULE # 1. 50: A DEMONSTRATION OF CRITICAL SEPARATION area to be searched Place the object in a representative part of the area to be searched International SAR Alliance Training Module 3

MODULE # 1. 50: A DEMONSTRATION OF CRITICAL SEPARATION object at midpoint Line up the searchers with the object at a mid-point – do not tell them where it is at this stage – ensure that the searchers on each end are further apart than CS International SAR Alliance Training Module 4

MODULE # 1. 50: A DEMONSTRATION OF CRITICAL SEPARATION who can clearly see it? Show them where the object is and ask the students who can clearly see it to raise their hands International SAR Alliance Training Module 5

MODULE # 1. 50: A DEMONSTRATION OF CRITICAL SEPARATION who can not see it? Ask anyone who can not see the object to leave the line and move to the side International SAR Alliance Training Module 6

MODULE # 1. 50: A DEMONSTRATION OF CRITICAL SEPARATION critical separation Take out everyone apart from the two on the end – these are at Critical Separation for the object in that terrain and ambient conditions International SAR Alliance Training Module 7

MODULE # 1. 50: A DEMONSTRATION OF CRITICAL SEPARATION distance between searchers Pace out the distance between the searchers to determine CS International SAR Alliance Training Module 8

MODULE # 1. 50: A DEMONSTRATION OF CRITICAL SEPARATION specified object The two searchers in orange are now at Critical Separation for the specified object in the terrain and ambient conditions that are to be searched. International SAR Alliance Training Module 9

MODULE # 1. 50: A DEMONSTRATION OF CRITICAL SEPARATION four searchers at cs The exercise is continued by using teams of 4 searchers at CS to search an area of about 80 m square of homogenous terrain International SAR Alliance Training Module 10

MODULE # 1. 50: A DEMONSTRATION OF CRITICAL SEPARATION search objects Search objects are labelled with a letter and the searchers record these (do not move/touch search target) as they move through the area. International SAR Alliance Training Module 11
