چکیده
This issue of the Annals of Occupational Hygiene is dedicated to the topic of heat stress evaluation. For this evaluation, several evaluation programs and international standards are available. In order to understand the reasoning and underlying theory behind these programs and standards, a basic knowledge of heat exchange processes between workers and their environment is needed. This paper provides an overview of the relevant heat exchange processes, and de®nes the relevant parameters (air and radiant temperature, humidity, wind speed, metabolic heat production and clothing insulation). Further it presents in more detail the relation between clothing material properties and properties of clothing ensembles made from those materials. The eects of clothing design, clothing ®t, and clothing air permeability are discussed, and ®nally an overview of methods for the determination of clothing heat and vapour resistance is given. # 1999 British Occupational Hygiene Society.

A strategy in four successive stages is described and justi®ed for the prevention and control of thermal problems in the workplace. This should allow these problems to be approached and solved progressively in small as well as large companies by relying successively, when necessary, on the complementary competencies of the workers themselves, their technical assistance, the occupational health ...

There is little doubt that heat stress aects many workers adversely and that protective clothing generally adds to the burden. The ACGIH threshold limit value for heat stress is the guiding document for evaluation of heat stress in the United States. Adjustment factors have been used to re ̄ect the change in heat stress imposed by dierent clothing ensembles. While the ®rst proposed factors sta...
