Course Overview

The I3 can detect a small amount of explosive particles, down to one billionth of a gram (the size of a grain of salt cut into a thousand pieces).

Pan Am 103, Lockerbie, Scotland

Trace

The I3 is just one more tool to help you improve your ability to detect Improvised Explosive Devices (IEDs).

Use it along with your X-ray, metal detectors, canine units, physical inspections, and current security measures.

How Do Explosive Traces Get Transferred?

• Explosive traces cling to anything they touch.

• Explosive traces transfer from person to person, person to object, object to object and airborne.

Trace

• Cargo, mail, and packages

• Conveyance access - Security access points, border crossings, checkpoints

• Baggage • Facilities protection -

government buildings, correctional institutions

• Remember, traces cling to surfaces• Determine areas for sampling• Load a sample trap onto the wand or wipe by hand, and

sample targeted areas

Materials and Equipment for Sampling

Sampling

• Insert the sample trap into the desorber.

• Wait for message:

Please Remove Sample

Equipment Overview

Place the sample trap into the desorber. Analysis begins automatically. Maintain control of the item you are

sampling. Observe No Alarm - Ready or

Explosives Detected on the display. Remove the sampling trap. If No Alarm - Ready, reuse the trap. If

Explosives Detected, discard trap and gloves.

Analysis

Analysis

Resolve the alarm in accordance with current SOP.

Examples: Contact your supervisor. Maintain control of item. Let the owner know that further

samples may be necessary. Decontaminate the work area.

Press the CLEAR button. In most cases the unit will

clear after an alarm. Otherwise, maintenance may be necessary.
