Experimental Thermal/Moisture Mapping of Industrial Safety Helmets

Abstract

This paper presents the research on thermal/moisture mapping of typical industrial safety helmets using match-head-sized sensors. Three types of the industrial safety helmet were tested, one without ventilation openings, one with small ventilation holes made by the researcher, and one with manufacturing ventilation openings in the top region. Up to eight subjects were tested for each type of helmets in various ambient conditions. Results give the original measurements of the in-helmet micro climate. Results also show some interested interaction between the in-helmet temperature and relative humidity.
