Abstract In dangerous working environments such as a Chemical, Biological and Radiological (CBR) exercise, a
protective suit plays an important role to increase work efficiency as well as prevent fatal damages. Air
gaps entrapped in protective suit play an especially important role in heat transfer. The distribution
and size of air gaps depends on body motions. The study developed 8 representative body motions
(stretching, walking, crawling, crouching, twisting, climbing and reaching, moving weights and lateral
bending) of CBR exercises of which 2-4 static body postures per each motion were derived. 3D body
scan was conducted on one male participant for the postures listed. Scanning was performed on both
nude and dressed bodies to measure the distribution and size of air gaps between human body and
clothing. As a result, curves and volume of the air gaps varied with the different postures. The results
serve as the basic data to improve protective performance of current protective suit.
