If the facepiece on the field protective mask collapses, what should be assumed about its condition?

If the facepiece on the field protective mask collapses, it is important to understand the implications of that collapse for the mask's functionality. A collapse of the facepiece indicates a significant problem with the integrity of the mask. Typically, the facepiece needs to create a proper seal against the wearer's face to ensure that it is functioning effectively and providing the necessary protection against harmful agents.

When a facepiece collapses, it suggests that there is a failure to maintain the proper pressure that is necessary for the mask to function as designed. Therefore, the mask should not be assumed to be airtight. An airtight seal is crucial for protection, as any leaks would compromise the safety of the user.

Recognizing the failure of the mask's integrity through the experience of a collapse allows users to understand that it is not suitable for use until inspected and repaired. This understanding helps in maintaining safety protocols and ensuring that protective equipment is functional in the field.
