Which method is combined with a hand search to enhance explosive detection?

The combination of a hand search with explosive trace detection significantly enhances explosive detection capabilities. Explosive trace detection involves analyzing a small amount of material or residues that may indicate the presence of explosives. This technique is particularly useful because it can identify trace elements that are not visible to the naked eye. When combined with a hand search, which allows security personnel to physically inspect and manipulate items, the effectiveness of detecting concealed explosives increases.

Explosive trace detection can provide a higher level of confidence in identifying threats, especially in scenarios where standard visual checks or physical inspections may miss subtle indicators. It allows for a more thorough examination beyond what visual or hand searches can achieve alone. Consequently, this combination serves as a powerful tool in maintaining security in aviation environments, where the presence of explosives poses a significant risk.
