1.) You should protect the dust masks from beeing crushed. When they are crushed the fit on the face may suffer. This would bypass the filter system. If the filter is of the sponge type crushing it will deform it over time. As the distance through the sponge is shortened the filter power is reduced.
2.) Using the wipes may leave residue which will alter the taste of your food. Good rinsing would be called for. Apart from that soap is cheaper.
3.) If it´s a real bugout scenario I´d be gone real fast. I would not try to encourage others to stay there for a longer time. If they don´t have it ready to grab and go, they can´t take it with them. Being a member of St. John´s I would report for duty a come back though.
