Final answer:
The option that is not a proper examination procedure is 'd. Open all biological evidence back to back' because it risks contamination. Other options such as wearing protective gear, cleaning workspaces, and documentation are correct lab practices.
Step-by-step explanation:
The question is related to the proper general examination practices and procedures used in a laboratory setting to ensure the integrity of evidence. The correct option that is NOT a proper general examination practice or procedure is d. Open all biological evidence back to back, as this could lead to cross-contamination. The other options, a. wearing personal protective equipment, b. cleaning the workspace, and c. documenting the condition of the packaging, are all essential practices that contribute to a safe and reliable laboratory environment.
Appropriate personal protective equipment such as gloves, safety glasses, or goggles is essential when working with cultures or in any situation where one might be exposed to hazardous materials. Furthermore, maintaining cleanliness in the workspace is vital to prevent contamination and ensure accuracy in experiments.
Documenting the condition of the packaging helps maintain a chain of evidence and can provide important information in case of any discrepancies. These examination practices are essential in various fields, including microbiology, medical, and forensic science.
