At MOPP Level 2, which gear is mandatory?

At MOPP Level 2, the requirement is to wear the protective mask. This level signifies a moderate degree of protection against chemical, biological, radiological, and nuclear (CBRN) threats, where the primary concern is the inhalation of harmful substances. By mandating the mask at this level, it ensures that personnel can protect their respiratory system from various airborne hazards, which is crucial for maintaining mission readiness and safety in contaminated environments.

While other gear options, such as gloves and boots, are important for overall protection, the mask is specifically classified as mandatory at this level because of the direct risk to the lungs and respiratory health from potential threats. Thus, wearing the mask becomes imperative to mitigate these risks effectively.
