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. Trace

Improvised Explosive Device (IED) Common Components:  Explosive material  Initiator/detonator  Power source/battery  Timer  Wires/IR Trace

Plastic Explosives:  RDX (C-4)  PETN  SEMTEX (PETN/RDX) Substances Detected Trace

Other Explosives:  TNT Trinitrotoluene  DNT Dinitrotoluene  NG Nitroglycerine  HMX Cyclotetramethylene tetranitramine  AMNO3 Ammonium nitrate  TETRYL Trace Substances Detected

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 Where is Trace Detection Applied? Trace

Which of the following can be detected with the VT2? Gun Radio lined with plastic explosive Heart medication Pepper spray Laptop with concealed explosives Stun gun Explosive traces on a car door handle Trace

What is an IED? What are some of the explosives the I3 can detect? What are some things the I3 cannot detect? Are explosive traces illegal? How are traces transferred? Trace

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

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

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. Clearing the Unit After an Alarm Analysis

What is the indication of an alarm? No alarm? What button do you press to clear the unit? What do you do with the trap after an alarm? Analysis
