Evaluation of the SciK9 Training Aid Delivery Device for Containment of Powders
Abstract
The SciK9 Training Aid Delivery Device (TADD) was invented by the U.S. Army Combat Capabilities Development Command Chemical Biological Center (Aberdeen Proving Ground, MD) to contain solid, powder, or liquid training substances. The TADD is designed to enable free gas/vapor exchange and simultaneously prevent escape of a training aid substance into the environment. This study demonstrates that the SciK9 TADD wholly contains powdered substances in the form of fine particulates and does not allow release of any trace material into the surrounding environment. Experiments were designed to evaluate short and long term stationary and dynamic containment of substances with a dry or wet membrane. In addition, formation of condensation within the lid of the TADD was determined. Caffeine and benzylfentanyl were used assurrogates for hazardous powdered narcotics and exposed to various experimental conditions. After analysis by mass spectrometry, no traces of these substances were found on the outer surfaces of the TADD. The results demonstrate that SciK9 TADDs can be used to safely train canines in the detection of powders such as narcotics after exposure to various experimental conditions.
