Search a wilderness area 300 feet by 300 feet (or equivalent
square footage) 6 hot items will be hidden and 3 blanks items
will be hidden for a total of 9 items. K9 must locate 4 hot items
within 60 minutes. In this test the 60 minutes is inclusive of K9
reward and break time. The dog must work through natural
occurring contamination and distractions. Only one false alert
is permitted. Samples (hot items) will be supplied by the
handler being tested. Samples must be able to fit into a 12
inch cylinder tube with a 1 ½ inch diameter. Blank items shall
be used to simulate contamination and distractions and will be
supplied by the OSDC testing officer and/or examiner. These
can include, but are not limited to food, tennis balls, dog toys,
etc. Items will be placed 30 minutes prior to testing under the
direct observation of the testing officer and examiner. Since
samples are difficult to obtain, hair,
nail clippings, extracted
teeth, and when the dog has trained with them, synthetic
chemicals such as "pseudocorpse" may be used.
