“…These regulations, however, are standards for housing and transportation of dogs and might not take into consideration the standards of working dogs. For example, one study examined the heat tolerance of military dogs, which revealed that they were able to withstand temperatures of 35°C up to 463 minutes (nearly 8 hours) depending on body condition [ 36 ]. Dogs are also able to adapt to certain environmental conditions, which allows them to build up a heat tolerance for specific environments needed for working standards [ 37 , 38 ] such as beach surveys.…”

Sea turtles are threatened with extinction around the world and rely on sandy beaches for laying their eggs. To protect eggs and locate them for calculation of reproductive success, beach surveyors must find the exact placement of each clutch. Eggs may be buried up to one meter deep under a nest mound several square meters in area. To locate sea turtle eggs, beach surveyors might spend hours searching for these eggs hidden in the sand, especially for difficult-to-locate leatherback (Dermochelys coriacea) and green turtle (Chelonia mydas) eggs. Scent-detection dogs (Canis lupus familiaris) are a novel tool that could provide a means to more accurately identify nests and efficiently locate eggs that need assessment, protection, or relocation. We assessed the effectiveness and feasibility of using a detection dog to locate sea turtle eggs buried in beach sand as compared to the traditional method using human beach surveyors. The detection dog was significantly more accurate in detecting loggerhead sea turtle (Caretta caretta) eggs and more efficient (less time spent and fewer holes dug) in assisting with locating the eggs. This case study presents results on the performance of one detection dog only, and additional research is needed with multiple detection dogs and handlers.

“…This is why thermoregulatory models are required. They have to be mathematical representations of the human, rationally constructed from physiology, heat transfer and thermodynamic principles [16] in order to achieve this aim. In addition to the controlled passive system, which describes the energy fluxes between a person and its environment, a prerequisite is that thermoregulatory models include a controlling active system.…”

“…The index needs to be ascribable to models providing a "rational representation of the human body involving heat transfer between the body and the environment, the anthropometry and thermal properties of the body and a dynamic (transient) representation of the human thermoregulatory system [1,16]". These are in first principles complete models of the human energy balance including passive and active thermoregulation which are integrated to steady state.…”

Selection of Appropriate Thermal Indices for Applications in Human Biometeorological Studies

Application of thermal indices has become very popular over the last three decades. It is mostly aimed at urban areas and is also used in weather forecasting, especially for heat health warning systems. Recent studies also show the relevance of thermal indices and their justification for thermal perception. Only twelve out of 165 indices of human thermal perception are classified to be principally suitable for the human biometeorological evaluation of climate for urban and regional planning: this requests that the thermal indices provide an equivalent air temperature of an isothermal reference with minor wind velocity. Furthermore, thermal indices must be traceable to complete human energy budget models consisting of both a controlled passive system (heat transfer between body and environment) and a controlling active system, which provides a positive feedback on temperature deviations from neutral conditions of the body core and skin as it is the case in nature. Seven out of the twelve indices are fully suitable, of which three overlap with the others. Accordingly, the following four indices were selected as appropriate: Universal Thermal Climate Index (UTCI), Perceived Temperature (PTJ), Physiologically Equivalent Temperature (PET), and rational Standard Effective Temperature (SET*).

“…A reliable occupational heat stress index should consider not only workplace environmental conditions but also activity levels and clothing properties [10]. The thermoregulation model can accurately simulate human thermophysiological responses by introducing the heat generation and heat exchange mechanisms of metabolism, respiration, skin blood flow and sweating, and considering the heat loss related to clothing and environment, it is widely used in predicting human thermophysiological responses therefore [33][34][35][36]. For example, the Predicted Heat Strain (PHS) model proposed by Malchaire et al [37] has been used to evaluate occupational heat stress [38,39] as an ISO standard [40].…”

Power grid outdoor workers are usually exposed to hot environments and could suffer the threats to occupational health and safety like heat strain and injury. In order to predict and assess the thermophysiological responses of grid workers in the heat, the clothing thermal insulation of grid worker ensembles was measured by a thermal manikin and a multi-segment human bioheat model was employed to evaluate the thermophysiological response parameters of grid workers such as core temperature, skin temperature and sweat loss. The results show that working in a hot environment can cause a obvious increase in core temperature and skin temperature of grid workers, and the acceptable maximum working time of grid workers varies greatly in different hot environments. A reasonable work organization strategy can effectively decrease the core temperature and sweat loss, increasing the duration of acceptable maximum working time for grid workers. This study is helpful to assess heat-related risks of grid workers and support power grid companies to rationalize work organization strategies and personal protection guidelines.
