Fire and Explosion Analysis - Part A

Property details (general description of where the fire took place)

There was no one at home at that time, especially in the burning kitchen. The kitchen had furniture and some household appliances. At the counter near the stove, a coffee maker, a toaster machine plugged into an outlet, there was a gas range clock on top of the toast and the time was 5:25 p.m. Crime Scene was situated at UTS Building, Level 00, U0 Building House Northeast of the 07 campuses of the house northeast of the UTS Building, Level 1 Lift 00 Lift 00 About 4 meters east If one walk, the entrance to the house will be CB07.00.07. The bedroom inside the house has 6 separate rooms, an office, storage room, a bathroom, a kitchen, a dining area and a communal house with a living room.

Background information/witness information

The discovery was made during daytime contact with the homeowner's family, when the children returned from school to see the whole house covered in smoke. They didn’t do it internally, and went to their neighbor’s house and called their parents and the fire department.

The fire department arrived and reported that the damage was confined to the kitchen, resulting in a smoldering fire in the kitchen.

The house is illuminated by a large circular bright light on the central ceiling and a square with an air of about 10 cm to the south. There were four small lamps in the four corners of the ceiling. The house has four white walls, a white ceiling and yellow crime scene tapes hanging across the entrance. At 0930 hrs, scan the room for room lights, fingerprints, marks and stains using three separate lights, white light, blue and green. A white circular mark was found on the carpet under the white round table under the white light to the north-east. 0945 hours when the lights are carefully searched from north-east to south-west in front and back. At the north-east corner and along the north-east wall is a round white table with three stacked white chairs and another white chair about 5 meters to the east (Aitao and Lingpeng, 2017).

The crime scene is located at the Sydney Institute of Technology (UTS) house 07, random 0. Building 7 is on the north-east side of the UTS campus. After going north through an automatic door on the northeast side, take about 10 steps to the northeast and go downstairs through the stairs. Walk about 10 steps ahead and take the elevator 00. One must swipe your UTS Student ID card to access the level. The interior bedroom has 6 separate rooms, an office, storage room, a bathroom, a kitchen, a dining room and a communal room with a living room.

The sitting room is 6 meters east of the entrance house 07, where the brakes and the entrance are located. The house has three white walls around the rectangle and the white wall on the south wall has a rectangular window covered with gray curtains. There is a gray concrete floor. There is an entrance where the scene of the yellow crime is taped. The house is bright and bright. There is a circular light in the center and four small circular lights in the ceiling at each corner. There is no ventilation or air conditioning. Along the south-west wall, there are two sofas under the windows. Along the east wall, there are two brown sofas with pictures of palm trees and white and blue striped pillows. Along the south-west wall, the brown sofa has a single-seat leather-green sofa about 3 cm west. A small long rectangular brown wooden recreation unit with three bogies along the north-east wall and Medium black TV on top of brown entertainment. There is a white wall clock on the north-east wall and a black TV. At 9:30 a.m., the room was quickly checked or clear markings or fingerprints on the outside of the yellow crime scene tape. At 09:35, the tape of the yellow crime scene was taken, a light switch on the southwest was cleaned, and a fingerprint was checked before searching the whole house. The light switch shows two complete fingerprints that take about 1015 hours. The fingerprint was deleted and packaged at 10:20 p.m. At 10:23, whole house was searched using the normal / white / blue / yellow light for markings and fingerprints. The central part of the window along the south-east wall was shown with three fingerprints which were later washed away. It shows partial fingerprints, a frustrated full fingerprint and a third advanced full fingerprint. After that, his picture is about ten-thirty. The fingerprint was taken at 10:40 pm and packed. All evidence is then given to Tash and Nicole (Fu, et al. 2016).

Description of damage

Several objects are being considered as evidence and damage has been found on their basis. The objects are counter tops, counter area, clocks, wall cabinets, outlets, toasters, chartered masses of electronics, coffee makers, glass carafe, baked potato chips, molten mass. Sert the spark and then spread the fire. The coffee maker was heated and embedded in molten plastic. The lower part of the wall cabinet is illuminated, the ward goes up and it becomes easier, it also affects the wall cabinet and the direction of the wall and changes color. The glass carafe got hot, the handle melted and the color changed. The wired and cord mass melts completely and spreads across the counter, creating an outlet for the wireless switch.

Beneath the white round table to the north-east is a blue and white carpet, about half of which collapses next to three decorated chairs. White round spots on the carpet were also noticeable A long light brown road with spots about 7 cm west of white spots. On the southwest side of the house is a red rectangular box in front of the gray door along the southwest wall. The red rectangular box has dry spots with footprints. 0951 hours when proof photography begins. The shoe print was made for 1100 hours. During 1115 hours, a tape lift with white spots on the carpet was made. Half of the circle is made up of two white tape lifts. During 1125 hours, a brown stain tape was picked up on the carpet. The long trail was divided into four sections where tape lifts were taken (Baalisampang, et al. 2018).

Laboratory result

After evaluating the evidence sent to the laboratory for testing, the coffee maker’s machine, external, electronic equipment, toast chart mass coffee maker’s machine is driven and the coffee maker is equipped with additional heating. It is an old model and completely melted [1]. Checking the outlet revealed that the cable connection was correct if the outlet was closed at any time during the fire during the "output" fire circuit breaker. The effective strain is affected by the melting of electric-sized masses and it is not possible to accurately determine whether it is on or off.

Evaluation of evidence (include discussion of hypothesis testing - what one ruled out and the reasons why you came to your conclusion)

Some inferences from the evidence continue as follows: (H-hypothesis, R-cause)

H1: Probably due to high power and ignition

R: Evidence is that the power switch was turned on by the coffee maker, the coffee maker lacked excessive heat protection, and the electric fire could have been caused by old wires, overloaded outlets, and extension cords.

H2: Due to limited space, the behavior of fire is perpendicular to the surface and it looks like convection behavior.

R: The possibility of flame removal is vertically upwards due to the impact of walls and wall cabinets, which can also distort the combustion pattern.

H3: Low-level heat is lost in the corners or on one side of the wall near the coffee maker.

R: Most structures are not affected by heat from the outside, which is easily seen from the ceiling and heat loss in one window. Only nearby items such as toasters, glass caravans and wall cabinets were burned.

H4: There was a burning smile

R: The clock in the oven didn't melt properly and there were no shots around it. The metal could condense at the bottom and was too hot to prevent surface reactions to vapor formation.

H5: The toaster was about to spread the flame.

R: Some toasters contain electrical components used to bake bread and bagels. If the toaster fails and does not stop, a fire may break out. The opportunity to monitor the toast and not to move the bread crumbs under the toast regularly flashes chance lab results The toaster is switched off and plugged into an outlet (Willey, 2017).

H6: Direction of flame flow from wall cabinet with glass window.

R: From the refractory part and experimental results, the lower counter part is completely protected from damage, and after the burnt part in the wall cabinet, the fire flow rises through the side wall and wall cabinet and can be said completely it passes through the burning window it flows oxygen Shows that the main parameters and angles of fire burn completely.

H7: The effect of igniting the fire is to move the ward upwards and intersect the sea voyage.

R: In synthesis, fire flows from the bottom of the sail to the place of the feather and over it. It is observable; the smoke of smoke can also affect the rest of the room and make it unconscious.

Conclusion (first fuel ignited, ignition source, area/point of origin, cause)

From the above lab tests, one came to the conclusion that we have learned what fire is and How does it promote and the behavior of fire and the process or scientific method behind it. The first fuel went through the coffee maker's machine and crushed the combustion as solid fuel. As a result of the experiment, it was noted that the coffee maker's switch was restarted and sparks were generated as a combustion source. Through virtual experimentation, the source area is the angle between the coffee maker and the kitchen exit from the kitchen cabinet to the wall and the angles propagated through the windows, due to the synthetic behavior of the main source of oxygen and then the source. It can be said that all objects burn.

A number of items were collected for analysis during the virtual operation, including countertops, counter areas, clocks, wall cabinets, outlets, toasters, electronic clad masses, coffee makers, glass carafe, baked potato chips.

One needs a wide range of analysis and conclusions that can identify the results and uncertainties of the analytical strategy of analysis. Probably the reason for the fire in the virtual lab for investigation was that the actual information of the investigation was not accurate and the root cause of the fire could not be identified properly.

Fire and Explosion Analysis - Part B

The causation forensic factors will be used to investigate why, where, and how the fire was occurred. This is often analyzed for the effect and damage of fire on the life and property. Through accurate observation and cautious identification, the burn temperature and fire possession on explosive and other materials, such as metal, fire as the specialist is helped to what is detected as the “the area of origin” of the fire. Generally, the fires will burn near or longer at the point of source, so the vulnerabilities will usually be favorable. In general, the source of the fire will come from that source or in a very short time and there is no unknown or accidental physical indication of the cause of the fire. When the location of the source has been determined, it can contradict or confirm the claim of the suspect/witnesses/owners/occupants. An important factor of a fire investigation is the appropriate identification, recognition, as well as the analysis of the exact signs of a fire in a compartment fire (Held and Brönnimann, 2016).

The following areas should be considered in the point of origin:

  • Determine different fuel and ventilation parameters
  • Identify the first fuel and ignition of origin in the house
  • The regions are least damaged and most damaged.
  • How long is the fire?
  • The effects of fire
  • Damage materials and areas in house: electrical products, furniture, structures and other equipment.

At the time of the investigation, I tried to recognize the cause of the fire as accidental or accidental. The causes of fires in three bedrooms made of brick, tile as well as timber construction would be electrical in which low quality wire, plugs, faulty switches, wet wires, low quality sockets, overloaded circuits, and switched on the electrical power products appears higher possibility. It looks to be cause. Along with that, laboratory test results should be monitored prior to making a final decision. It can list household firetraps, for example waste chemicals, plastic power, lubrication materials used for sprinkler head, and bathroom cleaner may register.

The bricks are over-burnt at the lowermost, while are under-burnt at the top. Moreover, the bricks can confuse the silhouette as well as the cause my be its descendent downward when the fuel layer was burnt. Moreover, the fire can be observed against the wall as well as this is noticeable in the V pattern.

At the time of the damage survey, the results of the investigation will present the reparation ended in the partition because of the size, shape and physical characteristics, the high flame temperature as well as the pattern and the damage because of the ventilation framework in the compartment.

Witnesses may be present at interrogation, occupants, stairs or pedestrians, victim's family, friends and suspects. Interviewing a witness from a different scene to use the most reported experience to benefit from a public investigation. Receive written statements of each witness at the police station. The questions for the interview are: the suspects to be scene at the scene of crime, the time of the explosion, the dimension of the house, the entrance, the equipment and the space? What is taken, if any? How are misconduct activities published? Interrogative researchers help their motivators make predictable mistakes when they are committed to seeking praise for what they have done or have done.

I briefly describe below the methods that will be used to inspect and record fire scenes, related to generally accepted publications.

Identify research requirements: I need to determine the existence of a crime or problem. In this context, if there is a fire or explosion, the location and damage must be recognized. The seat of the cause and the source will be determined.

Determine the problem: To complete this, the investigator has to explain the correct method. The data from these events were collected using scientific experiments.

Collect information. The evidence of such incidents is collected on the basis of observation, opinion, and interviewed the witness without any bias.

Analyze data. The data were analyzed based on the researcher’s skills, considering the need for interviews and analyzing using structured interview methods.

Develop Hypothesis: When conducting data analysis, the investigator makes assumptions about the type of spectacle to be cleaned, the type of fire, the cause of the fire, the source of the fire, as well as the responsibility and damage for the basis of fire.

Once it is determined that the fire has entered the master bedroom bed and the main fuel is loose clothing on the floor of the left room. The general bedroom setting then provides a source of combustible heat;

Wall or bar heater oil or electric: Fire can be started because of low quality of wall or rod heater. Laboratory analysis should be done on the quality of the material used.

Fireplace: The image does not show fire. If it was not the cause of the fire, no investigator would have seen the burning mark on the wooden floor that matched the furnace.

Lamps: Lights have bulbs that can stimulate the wattage so that it can light up and improve production conditions. If this tender mark appears on the right side of the plug. If the cause of the fire is not mild, investigators can expect that the administration is concentrating and shaking near the source, depending on the intensity of the fire.

Wall appliances: Such as laptop chargers, electric blankets; Wall appliances are very common in-home sets. Flood-colored clothing or fever can spread defects to attract electricity from electrical points and some electrical panels drain. Laptops and other chargers as well as electric blankets, humidifiers, night lights, clocks, fans etc. It requires laboratory analysis for official purposes (Chen, et al. 2019).

Problem Tear: In most cases the mattress is searched in uneven positions. The relative weakness is separated by the side of the bed near the open door. It could be the root of the fire.

Other observations: The post-fire inspections show signs of complex and powerful fires. In addition, the stockades are badly burned, floor level is marked. Moreover, the outline of two conspicuous burn are clearly identifiable as the partition is flowing. Systematic investigations have shown that the cause of this temperature is the fire in the bedroom that will be forced to control (Ji, et al. 2018).

In case, the conclusive attempt is made to reach a conclusion, the investigator must bring some materials for this test. Besides, any body fluids found at the crime scene, hair, glass pieces, plastic, wax, tar, oil, food items, cigarettes, and clothing items should be examined in the laboratory. In the event of injury or death due to fire, the full post-mortem forensic examination will examine drugs, alcohol, smoking habits and another sample. Earlier questions will be asked about the history of the victim, relatives, family, and friends. In addition, the criminal history of victims should be investigated.
