||Ergonomics evaluation of modified industrial helmets for use in tropical environments
||1988, Vol.31, No.9, p.1317-1329. Illus. 8 ref.
||Some selected safety helmets manufactured in industrialised countries (IC) were modified to provide extra head ventilation and to reduce weight, in order to make them more acceptable to users in hot environments in developing countries (DC). The modified helmets were subjected to ergonomic evaluation in the laboratory and in the field. White helmets had some advantages in comfort (reduction of hotness) compared to other colours (red, green, etc.) when worn in the presence of radiant heat in the laboratory. Ventilation holes provided at the top of the shell seemed to reduce the greenhouse effect within the helmet shell which therefore felt less uncomfortable than a fully covered helmet. Even with a small reduction in weight, such as 45g in helmets weighing about 350g, the difference in weight was perceived by the wearers. In adapting helmets made in IC for use in tropical climates, head ventilation and low weight perception are important aspects in comfort which need to be considered. In addition to low cost, a harness material suitable for sweat absorption is required. Adjustability and sizing to fit 90% of the user population also needs to be considered.
