Q

Steel risks

A

Unprotected Steel will expand and cause internal and external walls to be pushed out.

  • If sufficient fuel is used it will cause the steel to lose strength and cause the walls to collapse inwards.
  • When cooled, steel tends to contract and may fall off support or stay intact but may collapse at any time
  • Pay attention to the location of the steel and conditions of beams.

Q

Concrete risks

A

Concrete, in particular concrete slabs are unpredictable as they can be effected by low heat.

  • it may cause the concrete to topple over, in any direction.
  • When exposed to fire, concrete can fall away and cause spalling.
  • This may expose steel and the steel may lose its strength.

Q

In suspicious fatal fires what consideration must be done with the spoils from the fire.

A

Storage:
cleared warm area of your scene if practical and should be clearly marked where the spoil has come from in your scene. This provides the investigator with a backstop should you need to revisit your search

20
Q

Pre Examination

A

1) The scene should be examined systematically, from the outside in.
2) clear area for material removed during the search, and avoid any cross-contamination potential.
3) Set clear areas of responsibility (co-ordinated approach)
4) Successful fire investigation requires a logical, step by step approach commencing in the undamaged area and progressively working through to the point of origin.

21
Q

External examination

A

Takes in account:
•What distance debris was scattered, particularly if drums or cylinders have exploded.
•The periphery of the structure itself
-attempts at forced entry
-attempts at forced entry
•burn patterns above doors and windows and “V” shaped burn patterns on external cladding.

22
Q

Prelim Examination

A

The preliminary internal examination should involve a slow walk through the premises, from the area of least damage to that of most damage, taking note of indicators such as:
•burn patterns
•low stock levels in commercial premises
•missing family photographs, furniture and personal items
•open filing cabinets or missing files
•presence of accelerant containers or trails
•separate unrelated seats of fire

23
Q

Detailed internal examination

A
you will accompany the Specialist Fire Investigator while they complete a detailed examination:
•smoke deposits and burn patterns
•spalling (the cracking or chipping of concrete as a result of being heated and cooled)
•damage to wall studs
•damage to roofing timbers
•damage to windows sills and door edges
•soot deposits on window glass and craze patterns
•floor areas burned through
•skirting board damage
•elimination of false low burns
•removal of fire debris, and
•under floor inspection.
24
Q

What is crazing

A

of glass can be created by the rapid heating of glass and also the rapid cooling of it by the application of water spray in a hot environment. It is notan indication of the use of a flammable liquid without other indicators being present also.

25
Q

What must be considered when determining the seat of the fire?

A
  • witness’ reports
  • when they first noticed the fire, and where they were at the time
  • the state of the fire at that time
  • wind direction and speed, and the weather
  • the direction of spread
  • the colour of the flames and smoke (this may also point to the cause; for example, black smoke may indicate a petroleum product based fire)
  • the severity of the damage (because fire and heat usually rise, the area at the lowest level of burning with the most severe damage is often the place where the fire started. Remember that lateral and downward burning can occur with some materials and in the presence of accelerants or draughts)
  • the depth of charring (probing may indicate where the fire has been burning or smouldering the longest)
  • the presence of ‘starting devices’
  • the reports and opinions of other specialists.
26
Q

Exhibits

A

1) Photograph in situ, label the exhibits, and preserve them in container
2) Use approved arson kits if these are available; if not, use any suitable containers such as unused four litre paint tins
3) Take control samples:

27
Q

Control samples

A
  • charred timber and ashes or debris from the seat of the fire for examination and comparison with samples from other points
  • any accelerants found near the scene
  • soil from the surrounding area.
28
Q

What info do you cover off in prelim interview with owner:

A
  • when the premises were last secured, and by whom
  • whether he or she knows the cause of the fire
  • the details of any suspects and any insurance
  • type of business
  • actions leading up to the fire.
29
Q

Conducting area enquiries

A

1) conduct area enquiries
2) prelim interview with owner
3) note owners demeanour
4) Complete, obtain statements from, informant witnesses
5) give SITREP to supervisor

30
Q

Why hold a conference

A
  • assessing information obtained
  • reconstructing
  • establishing possible motives
  • identifying suspects
  • planning further enquiries.
31
Q

Who attends conferences

A
  • O/C CIB
  • crime scene co-ordinator
  • Fire Investigation Liaison Officer
  • O/C Investigation
  • investigating officers
  • Specialist Fire Investigator
  • Police photographer
  • fingerprint technician/SOCO
  • other specialists as required.
32
Q

What to look for with explosives

A
  • cratering
  • spread of debris
  • shredding of materials
  • a smell peculiar to the exploded material; for example, the smell of almonds is often associated with explosive or exploded material
  • an overlay of dust
  • shrapnel marks.
33
Q

What traces of the detonator will remain after an explosion depends on..

A
  • How far it was placed into the explosive
  • If inserted well inside, you will likely only find the fuse.
  • If the detonator was not well placed, likely to find fragments of the detonator itself.
34
Q

What to look for with electric detonators

A
  • lead wire, which may help identify the type of detonator used - the remaining wire is often referred to as ‘fly wire’
  • the neoprene plug
  • the short-circuiting shunt - a small piece of plastic that is removed from the wires before they are connected into the circuit
  • the ‘delay setting’ tag from the lead wire
  • fragments of the electric detonator casing (although this is highly unlikely).
35
Q

Safety fuses

A
  • Burning leaves fusing in limp state but still should be able to ID colour and manufacturer.
  • Explosion may blow fuse of original course
  • May find path by following scorched path from point of ignition to centre of explosion
36
Q

Detonating cord

A
  • Generally leaves little residue.
  • Surfaces on which it is laid may be damaged.
  • May find cut of pieces that havent detonated eg laid on sharp angle
  • Be aware trailers may still be located under debris.
37
Q

When disassembling an IED

A
  • Discuss with IED operator a non-destructive method to preserve evidence
  • Safety over evidence preservation
  • Ask the IED operator to visually record as much as possible
38
Q

Fires involving explosives:

Initial action

A

1) May be secondary device
2) dont use cell phones or portable radios
3) Evacuate the scene to 100metres. Ensure people leaving bring personal items with them to limit the number of items to be cleared- consider bomb dog
4) IF IED located use IED operator from Department of labour or defence force.
5) Give SITPREP to comms

39
Q

Examination explosive scene

A

1) Use a recording device-videos-photographs
2) Remember to continually reconstruct
3) Request ESR

40
Q

A low powered explosion will

A

explode in a general manner, causing damage and spreading debris over roughly the same distance in all directions.

To have any real effect they need to be confined-eg a pipe-which would make them a high powered explosive

41
Q

Explosives of 5000mps

A

Explode up and down
Cause great directional damage
People who make these are generally experienced in making IED’s

42
Q

Explosives that explode at a rate of 1200 - 5000 MPS

A
  • damage occurs in a ‘least line of resistance’ pattern

- ie widows, windows, light walls blow out.

43
Q

Because morder explosions dissipate rapidly, O/C may need expert to enter scene

A
  • Create path to centre of explosion
  • swab area.
  • street signs generally have good residue.
  • Ensure tools are clean
44
Q

Suspect of an explosion

A
  • Leave “signature”

- consider tool marks, foot prints

45
Q

Bodies-explosions

A
  • Seek pathologist help
  • Consider x-rays to ID exhibits
  • Consider motives i.e suicide, terrorist
46
Q

Reconstruction of explosive

A
  • under the supervision of the O/C scene
  • at a suitable range or site
  • in conditions as close to those of the original explosion as possible
  • in close association with explosives and scientific advisors
  • as a scientific test.
47
Q

Initial action-non explosive

A

1) informant may be offender
2) Secure and Control scene
3) interview Specialist Fire invest gator and O/C of first appliance on scene.
4) Interview Incident controller
5) Once fire extinguished-ensure safety of the scene
6) If deem suspicious-regroup -hold briefing conference
7) Confer with other staff and determine a plan of action i.e scene guard, witnesses, enquiries
8) Give comms a SITREP
