“…This can be seen in a 16% decrease in driving performance in cold (5°C) compared with neutral (20°C) environments (Daanen et al 2003). Cold environments often have decreased traction through the presence of condensation, ice, or snow, with greater risks for slips and falls.…”

Many physically demanding occupations in both developed and developing economies involve exposure to extreme thermal environments that can affect work capacity and ultimately health. Thermal extremes may be present in either an outdoor or an indoor work environment, and can be due to a combination of the natural or artificial ambient environment, the rate of metabolic heat generation from physical work, processes specific to the workplace (e.g., steel manufacturing), or through the requirement for protective clothing impairing heat dissipation. Together, thermal exposure can elicit acute impairment of work capacity and also chronic effects on health, greatly contributing to worker health risk and reduced productivity. Surprisingly, in most occupations even in developed economies, there are rarely any standards regarding enforced heat or cold safety for workers. Furthermore, specific physical employment standards or accommodations for thermal stressors are rare, with workers commonly tested under near-perfect conditions. This review surveys the major occupational impact of thermal extremes and existing employment standards, proposing guidelines for improvement and areas for future research.Key words: Heat stress, cold stress, occupational physiology, testing, work.Résumé : Plusieurs emplois physiquement exigeants dans les économies développées et en émergence s'exercent dans des milieux thermiques extrêmes qui peuvent affecter la capacité de travail et, en fin de compte, la santé. Ces milieux de condition thermique extrême se retrouvent dans des environnements de travail intérieur ou extérieur et peuvent découler d'une combinaison d'un milieu ambiant naturel ou artificiel, de la production de chaleur métabolique due au travail physique, des procédés spécifiques au milieu de travail (p. ex. fabrication de l'acier) ou du port obligatoire d'un équipement de protection s'opposant à la dissipation de la chaleur. Globalement, l'exposition à la chaleur peut diminuer ponctuellement la capacité de travail et générer des effets chroniques sur la santé, augmentant ainsi le risque de maladie chez le travailleur et la diminution de la productivité. Étonnamment, dans la plupart des emplois même dans les économies développées, il y a rarement, à propos du froid et de la chaleur, des normes de sécurité ou des règlements en vigueur à l'intention des travailleurs. De plus, rares sont les normes spécifiques aux tâches physiques ou les accommodations aux agents de stress thermique et les travailleurs sont généralement évalués dans des conditions presque parfaites. Cette analyse documentaire sonde les effets principaux des agents thermiques extrêmes sur les tâches physiques, fait le bilan des normes en vigueur en matière d'emploi, suggère des lignes directrices et des pistes pour des études ultérieures.

“…Havenith and et al (2002) have shown that the effects of thermal comfort of reductions in vapor resistance due to air and body movements are also shown to have a substantial impact on the comfort limits in terms of skin wettedness and cannot be neglected either. Having control over the local head temperature by adjusting a heater/blower does not affect thermal comfort or driving performance, as described by Daanen et al (2003). According to Yamashita et al (2005), thermal comfort in autos is observed to depend closely on the inter-relation between local airflow temperature and ambient temperature.…”

“…In another study [8], the tests were conducted on a group of fifty people, who were randomly selected to drive under three different climatic conditions: under cold, neutral and hot conditions, which corresponded to 5 o C, 20 o C, and 35 o C, respectively. In all the cases, the same relative humidity conditions of 50 % were maintained.…”

Abstract. There are several important factors influencing road accidents. Temperature inside the vehicle is ranked third after alcohol and seat belts. For this reason, maintaining thermal comfort in the passenger compartment is essential. Thermal comfort is provided by the air conditioning system, which consumes much energy. In the case of electrically powered vehicles, this results in a shorter range. Optimization of such systems is therefore required. This paper proposes a set of equations describing the thermal conditions inside the vehicle, which are the result of appropriate energy balances for air, interior elements, and glass. Variable transmission conditions are included for transparent materials exposed to short and long wave radiation. The study focused on unsteady air-conditioning of the vehicle interior. The measurement data was compared with the results obtained through numerical solutions of the proposed set of equations.
