This program was conducted to establish the design characteristics of attachment mechanisms for use in the mounting of mask seals and specialty components into the Respiratory Protection System 21 (RESPO 21). These design characteristics include but are not limited to keeping the seal/attachment mechanism low in profile, allowing easy seal or component replacement, and incorporating multiple layers of material within the seal and attachment mechanism. Alternative seal concepts were investigated for the interface between the mask ad the mask wearer. These concepts include pneumatic bladders, encapsulated gels, laminated foams, and combinations of the above. Prototype seals of the encapsulated gel-type and the pneumatic type were fabricated to demonstrate feasibility and assist with the development of attachment mechanisms. Approaches for attaching a seal to a mask, both hard-shell and soft- shell, were identified. None were fabricated due to time limitations and availability of appropriate seals and masks. |
