Abstract:

Face masks were tested under field conditions at Pole Station, McMurdo, Byrd Station, and Hallett Station. Weather conditions varied from temperatures of 4F, 30 knots wind, daylight but cloudy to -75F, 17 knots wind and night. The face mask keeps the wearers face warm and will provide protection to the eyes from cold and glare. Observers comments are as follows 1 Limited field of vision. 2 Inability to wear glasses with mask. 3 Excessive resistance to breathing. 4 Collection of condensation andor mucus on face side of mask with the subsequent leakage of these fluids from lower edge of mask and freezing or running down neck. 5 Mask makes communication speaking or hearing difficult. 6 Proper and comfortable fit of mask to all wearers is difficult. 7 Having a beard reduces the efficiency of the mask, but two of observers that had no beards reported lower part of the mandible getting cold. 8 Inability to wear some types of issue hatscaps with the mask.
