I worry that those working with minimal/no protection in the project will catch some horrible disease/illness. The longer term intention of persuading folks to use dustbins should certainly help IF the contents can be disposed of regularly and responsibly.
Reminds me of a lecture I went to by Professor Les Baillie of Cardiff University, one of his photos showed him dressed in bin liners as protection when dealing with anthrax in the ground, while others wore bio suits.
