Which action is advised to control the spread of infectious diseases during an incident?

Implementing strict hygiene protocols is crucial in controlling the spread of infectious diseases during an incident. This approach involves measures such as frequent handwashing, the use of personal protective equipment (PPE), proper waste disposal, and sanitization of surfaces. By maintaining high hygiene standards, the risk of transmission among personnel is significantly reduced. In environments where infectious diseases may spread quickly, adherence to these protocols serves as a primary defense mechanism.

The other options may not effectively address the need to contain infections. For instance, quickly evacuating all personnel could lead to crowded areas where the risk of spreading the disease increases. Similarly, using air units for dispersal is not a recommended action, as it could further spread airborne pathogens rather than contain them. Limiting communication among crew members may hinder coordination and response efforts, but it does not directly contribute to infection control. Therefore, implementing strict hygiene protocols stands out as the most effective strategy.
