Heat stress in workmen in an aluminum plant in Southern Louisiana has been reduced by providing a microenvironment of cool, clean air for each man, a more efficient practice than any of the older methods of mass air movement, or radiant heat shielding, or spot cooling on the job site. An individual lightweight vortex tube unit operated on compressed air and worn at the waist is now used to deliver cool filtered air to the head and trunk through flexible tubing beneath a simple fabric hood and ordinary work clothing.
