At MOPP level 2, which of the following is true?

At MOPP level 2, personnel are equipped for a heightened state of readiness to protect themselves against chemical, biological, radiological, and nuclear threats. This level includes wearing overgarments, which serve to protect the body from contamination, while the mask is not worn but is required to be carried for immediate access if the situation escalates. This setup strikes a balance between protection and comfort, as the mask can be cumbersome when not needed, but its readiness is critical should the alert status change.

The correct understanding of MOPP levels is crucial for personnel safety and operational readiness. At this level, personnel must also remain vigilant and prepared to don the mask rapidly if conditions warrant it, making the carrying of the mask a key aspect of maintaining this preparedness while minimizing the discomfort of wearing it continuously.
