Final answer:
Personnel in contaminated areas should use PPE, follow strict decontamination procedures for themselves and tools, handle contaminated waste properly, and may need to set up evacuation zones in extreme cases. Labs with BSL-2 bacteria require additional safety practices. Information on ingested radioactive materials is essential to assess potential damage.
Step-by-step explanation:
When working in contaminated areas, personnel should take specific safety measures to mitigate risks. First, they must wear appropriate personal protective equipment (PPE) such as a protective coat, face protection, and cut-resistant gloves. If there is any contact with skin, immediate washing with detergent and warm water is necessary, followed by washing with 1 N NaOH or a 1:10 dilution of bleach for 1 minute.
Dealing with contaminated waste involves its incineration or autoclaving in a strong basic solution. Similarly, instruments must be cleaned thoroughly and soaked in a strong basic solution to ensure decontamination. In scenarios of severe contamination, such as after an accident involving radioactive materials, it could also be necessary to remove contaminated waste and establish an evacuation zone around the affected areas.
In the specific context of working with BSL-2 bacteria in a lab, additional safety practices must be strictly followed to prevent infections and contamination spreading. When accidental ingestion of radioactive material occurs, it's crucial to gather information on the quantity and type of radioactive material consumed to assess potential damage and necessary medical response.
