Identify two key laboratory safety measures when handling suspected biological agents.

Explanation:
Handling suspected biological agents requires layered safety controls that combine engineering, personal protection, and administrative practices. A biosafety cabinet provides proper containment during procedures that could generate aerosols, reducing exposure to workers. Wearing appropriate PPE adds a personal barrier against contact with infectious material. Limiting aerosol-generating procedures further lowers the chance of releasing aerosols into the lab environment. Implementing containment and chain-of-custody for samples ensures the material stays within a controlled, traceable system from collection through analysis, which protects both safety and the integrity of the investigation. The other options miss one or more of these essential protections, such as omitting containment or PPE, or neglecting the need for controlled handling and documentation.
