Samples of potential chemical interferences were also prepared by placing samples of selected materials inside clean cardboard boxes. The potential inter-ferent items were materials commonly encountered in demining operations such as petrol. These materials were sampled in an identical fashion as the positive samples. Blank samples were also prepared by sampling empty cardboard boxes. All samples were marked by sampling personnel in a manner that made it impossible for analysts to determine the composition of the sample during analysis. Nomadics personnel and dog handlers were not given any information on sample identity until analysis of samples was completed and results were submitted for scoring (i.e., the tests were conducted in a blind fashion).

A disadvantage of mixtures of liquid oxygen with combustible substances lies in their high sensitiveness to impact and friction. This property depends largely on the composition of the combustible material used. Oxyliquits containing sawdust show the lowest sensitiveness, while those containing hydrocarbons (e.g. naphthalene) pitch or petrol are more sensitive. [Pg.493]
