Final answer:
In a forensic lab, a vault may be necessary to securely store highly sensitive or dangerous materials, such as hazardous chemicals, drugs, or firearms.
Step-by-step explanation:
In a forensic lab, a vault is not typically required. However, there are certain situations where a vault may be necessary to store highly sensitive or dangerous materials.
For example, if a forensic lab deals with hazardous chemicals, drugs, or firearms, a vault can be used to securely store these items to prevent unauthorized access and protect the safety of lab personnel.
Overall, while a vault may not be a standard requirement in a forensic lab, it can be an added security measure in specific situations.
