Q

What are the safety risks associated with steel? [Must know]

A

Unprotected steel will expand, causing walls to push out. If sufficient fuel, steel will lose strength and collapse, pulling walls inward. It may also collapse during excavation or movement.

When cooled steel will contract and may fall off its supports.

Steel will rarely melt, but at 1600°C its strength will drop to 10%.

  • character, mental background, history, movements, and behaviour
87
Q

Where should you consider executing a search warrant and what should you look for? [Must know]

A

Suspects home, vehicle, work place etc.

Look for accelerants, containers, igniters, debris from the scene, wicks, containers etc

Comply with exhibit handling processes and conduct further inquiries based on what is located.

88
Q

Following a search warrant, what final suspect enquires should you conduct?

A

Regular suspect enquires including:
- Interview the suspect
- consider photoboards
- enquires addressing the suspects alibi or defence
- Discuss prosecution with supervisor
- Arrest and obtain particulars and identifying features
- Complete prosecution file, outstanding NIA tasks and submit a noting to FILO

89
Q

What step should you take in a fire investigation to preserve electrical evidence?

A

Turn off the main switch, not all breakers

90
Q

What questions should you ask in an electrical fire?

A
  • was power to the building on?
  • was power to the specific area of the building on?
  • was there electrical continuity to the heat source
91
Q

What initial action should be taken at an explosion scene?

A
  • Consider secondary devices in nearby buildings and vehicles. Do not have deal with anything unfamiliar.
  • Do not use cellphones, radios or transmitting devices
  • Evacuate scene to 100m and get people to take personal effects
  • Consider a detector dog
  • If IED located, request IED operator from Department of Labour or defemce force
  • SITREP for comms
92
Q

Discuss conducting a scene exam of a fire with explosives

A
  • Once declared safe, conduct a scene exam using photos and video
  • Continually reconstruct
  • Request attendance of a suitable ESR analyst and get them to bring stabbing equipment
93
Q

How will a low powered explosive explode? And how are they made to be effective?

A

In a general manner, spreading over the same distance in every direction.

They need to be confined (e.g. a pipe) to be effective and provide more power.

94
Q

How to medium powered explosives of 1200-5000 mps explode?

A

They will explode in a least line of resistance pattern. This means windows, doors and light walls will blow out

95
Q

How do high explosive materials over 5000mps explode?

A

In a directional manner, causing great directional damage, but less than expected in other directions.

96
Q

What consideration must be given to modern explosive residue and what steps should be taken given this?

A

It is slight and dissipates.

O/C may need to authorise an expert to enter the scene before it is fully examined. If so:
- Create a path with stepping plates or a plastic sheet
- Get ESR analysis to start stabbing ASAP from the seat of the explosion out
- look for vertical sheets of iron, such as signs for fencing, will provide good sources of residue
- avoid fross contamination of tools

97
Q

Other than interpreting the strength of an explosive, how else can you identify the explosive?

A
  • Analysis
  • odors
  • removal of body parts from the scene to prevent decomposition and subsequent examination
98
Q

What are the key 2 points for exhibits from an explosion?

A
  • Package exhibits in containers
  • Only seize that which will help the investigation
99
Q

How can you try to link an explosion to a suspect beyond regular arson enquiries?

A
  • Look for fingerprints and handwriting samples
  • IED operators may be able to ID a “signature”
100
Q

What steps and considerations should be taken for bodies at explosion scenes?

A
  • Obtain the services of an experienced pathologist to obtain evidential material from people who died
  • consider x-rays to locate exhibits in bodies
  • Consider suicide/terrorism
101
Q

If you are able to ID an explosive via scientific analysis, consider reconstruction. How must this be done?

A
  • Must be approved by the O/C
  • Must seek to recreate the original blast and environment
  • Must be done under specialist advice
  • Capture it with photos and videos
102
Q

What are the characteristics of explosive damage?

A
  • Cratering
  • spread of debris
  • shredding of materials
  • odors particular to exploded materials e.g. smell of almonds
  • an overlay of dust
  • shrapnel marks
103
Q

How can you identify a gas explosion?

A

It will generally cover a larger area and not crater.

104
Q

How can you identify the type of gas from an explosion?

A

Lighter than air gas will create an outward explosion at the top of walls. Heavier than air has will blow out the bottom of a wall.

A victim may also have inhaled gas before the explosion. Consider Post mortem.

105
Q

Where may you find the container for an explosive device?

A

It may be scattered over a considerable distance

106
Q

What will affect the locating of non-electric explosive detonators?

A

How hard it was pushed into the explosive. If inserted well, you will likely only find the wick. If not, you may find fragments of the detonator itself.

107
Q

What should you look for at a scene where an electric detonator was used?

A
  • fragments of the detonator casing
  • lead wire
  • delay setting tab from lead wire
  • short-curcuiting shunt
  • neoprene plug
108
Q

Discuss safety fuses for explosion investigations

A

You should be able to ID the colour and manufacturer.

The explosion may blow it off its path.

109
Q

Discuss investigating explosions with detonating cord

A
  • It leaves little trace, however the surface in which it was laid may be damaged
  • Undetonated cord may remain
  • Trailers may also be found under fallen debris
110
Q

How can you identify if igniter cord was used in an explosion?

A

It will spark brightly as it burns, leaving a black charred, ash-like remnant.

It will leave less than a safety fuse.

111
Q

On top of containers and detonators, what other physical parts of an explosive device may remain after an explosion?

A

Explosive wrappers and packing material

112
Q

How should you try make a explosive device safe? Should this always be the method used?

A

Encourage the IED operator to use non-destructive means. However, safety trumps preservation of evidence.

If it must be destroyed, consider getting the IED operators to record their initial assessment of the device

113
Q

When using a fire investigation sampling kit you must ensure that…

A
  • samples are not cross-contaminated
  • containers are sealed and labeled
  • liquid samples are secured and isolated
  • the kit is forwarded as a unit
  • the package is clearly addressed
114
Q

How should you package liquid samples?

A

In the bottles provided in an arson kit. Ensure the tops are fastened, clean the outside surface, then place in a polystyrene box.

If possible hand deliver.

115
Q

How should you package liquid residues?

A

Uplift with a clean pipette and treat and a liquid samples or absorb into a tissue and place in a tin.

116
Q

A

A Rural Fire Invetsigator

117

- direct water supply
- close roads and railways in the vicinity
- remove vehicles and break into them if necessary
- use reasonable force to remove persons who are in danger or are interfering
