What are the aims and objectives of a crime scene report?
Presentation to a court in trial
preventive/security reasons for follow-up operations
matching witness/perpetrator statements against evidence/traces on scene
Explain the term soak times (primary/secondary) and their purposes!
A soak time is a waiting time for an IEED Operator before approaching an explosive device/suspicious object
Primary Soak Time —> Waiting time before initial action. Normally one hour, counted after the place where the suspicious object is, was locked down. The purpose is to avoid an approach at likely times of explosion.
Secondary Soak Time —> Waiting time after every IEDD action on the suspicious object by the IEDD operator. This time varies and depends on the situation. It is taken because the action might have set something off inside the IED. The purpose is to avoid being close to an explosion caused by an IEDD action.
What are the 4 phases of a hand entry IEDD operation?
entering/cutting/opening the container of the IED with the right tools
Seperation (detonation circuit from explosive, and explosive from container)
Which legal problems occur in case of the use of x-ray technique on a human body?
The Röntgenverordnung doesn’t have an exception for law enforcement.
It states that x-ray is only allowed:
for medical purposes
for especially licensed medical personnel
only with equipment that has been tested and approved for the use on humans
Give some examples for tools for general disruption!
mineral water bottle disruptor
linear focused charge
What are the advantages of water as a medium in a disruptor?
Water is not compressible, therefore it is an ideal medium to transfer energy
Water distributes after a short way, disrupting the inner components of a suspicious object
Water reduces the danger of a high order detonation by pre-wetting the explosive material, therefore lowering its sensitivity
Water is a light medium —> reduces the energy delivered to the explosive
Which physical reasons can cause a high order explosion during an IEDD operation using a disruptive tool?
The destruction of the ignition system is slower than the reaction time of the ignition circuit
the energy delivered to the explosive material by the disruptive tool, is enough the ignite it (explosive itself is too sensitive)
