Final answer:
Precautions in collecting laboratory specimens include labeling the specimen fully, taking all sterile precautions, and sending the specimen to the laboratory without delay. When working in BSL-1 or BSL-2 labs, safety practices are critical to prevent accidents such as skin punctures, mucous membrane exposure, and accidental ingestion of infectious material.
Step-by-step explanation:
Precautions in collecting laboratory specimens include ”d) All of the above”. This means that one should a) Label specimen fully, clearly, and accurately, b) Take all sterile precautions, and c) Send the specimen to the laboratory without delay. When working with biological specimens, especially in settings that involve Biosafety Levels (BSLs), following strict safety protocols is paramount. For instance, BSL-1 or BSL-2 labs require specific safety practices such as:
- Accidental skin punctures prevention by careful handling of sharp tools.
- Protection against mucous membrane exposure from culture splashing.
- Avoiding accidental ingestion of infectious material.
Additionally, proper biohazard signage and handling equipment should be used for BSL-2 agents. Disposal of biological cultures, such as those grown on agar plates, requires sterilization before disposal to prevent the spread of infectious agents. Following these guidelines ensures the safety of lab personnel and the integrity of the specimens.
