Ppe Investigation Report
PPE is a vital part to an investigation; not only for preserving the crime scene but also ensuring the safety of the forensic scientist. PPE comes in all shapes and forms, ranging from latex or nitrile gloves,bubble suits, face masks, eye protection etc. In this lab, the group investigated the living room where a suspected stabbing occurred (living room 1). The PPE required for this investigation included: latex gloves, disposable filter masks, and shoe covers. Each piece of PPE was significant to protect the forensic scientist against exposure (1). The latex gloves fall under the chemical protective clothing which is an inexpensive PPE that protects the forensic scientist from various chemical or biological exposures; such as blood, urine,

There are many ways to collect evidence. The different collection methods depend on the type of evidence being collected. All evidence should be secured and documented as soon as possible with the proper collection techniques. In this lab, i was responsible for the unknown brown fibrous strands (hair). It was found in on the sofa across from the possible murder weapon.
The proper way of collecting the hair strands include using clean and sanitized forceps to collect the strands and then placing it in a manilla evidence envelope (1). Gloves must be worn to ensure no cross contamination occurs. The envelope must be sealed and labelled and then passed on through the chain of custody.
To ensure authenticity and legitimacy of the evidence a evidence tag must be placed over the opening (2). The tag must include the forensic scientist’s name and initials (the one who secured the evidence), the date, time, the type of evidence, exhibit number,where it was found and the department supervisor. For example the hair sample i found would be documented as “ Exhibit 1, Unknown hair sample, Living room 1, Zunash Saleem (Z.S) and Jaycee Morrison” (1). The evidence tag comes with a pre-printed identification form, the scientist fills in the blanks, and passes it along the chain of …show more content…
The forensic Scientist cannot exclude their of them from the crime scene profile. The suspect has a higher probability of being involved in the crime compared to other possible suspects (1). Furthermore if both individuals DNA is found, the forensic scientist can conclude that there is a possibility of rough play, or physical interaction between the two individuals(3). This information can then be built up, by comparing any possible bruises or marks, and using the other evidence found at the crime scene to build a strong suspect and crime scene
