Title Use of a ventilating hat.
Bibliographic information Sep. 1978, Vol.7, No.1, p.90-92.
Abstract A hat designed to reduce the heat stress of outdoor workers exposed to solar radiation is described. It is made up of a double sheet forming a soft crown, with a lining and 2 openings for ventilation. A disk with a wet pad on it is attached to the top of the hat producing a chimney effect. Experimental and field tests showed the ventilation effect to be positive in terms of increased air flow rate between the hat and the head, and of the slower increase of inside temperature.
