Abstract:

In order to identify some of the problems involved in protective mask training, small groups of medical volunteers were tested in exhausting work before and after 3 or 8 days of training. The men wore M9 and M17 masks with filters removed and with various inspiratory and expiratory resistances added. In addition to the resistance of the filter, the facepiece without the filter had a degrading effect on endurance. Available evidence indicates that physical fitness is a factor in endurance while wearing the protective mask. In inexperienced men the ratio of endurance when masked to endurance when unmasked is not affected by fitness.
