  • Empirical validation of a new heat stress index

    Thermal stress is a well-recognised health hazard in the workplace. In addition to the health deficits, working in the heat can impact significantly on the productivity of some industries which are located in harsh environments. A long-standing dilemma in OHS has been the specification of what constitutes a safe working environment. The current indices used to evaluate the environment are either ...

  • Self-pacing as a protective mechanism against the effects of heat stress

    Objective: Self-pacing or avoidance of physiological strain by adjustment of work rate may be an important protective behaviour for manual workers in severe thermal conditions. Data were gathered at a number of industrial sites in the United Arab Emirates to assess whether self-pacing takes place in these workers. Methods: Heart rate and aural temperature were monitored in 150 subjects for 12 h ...

  • Assessment of cracking in concrete due to hydration heat and autogenous shrinkage

    An experimental study was conducted to simulate the generation of thermal stresses due to hydration heat and restraint by using a thermal stress measuring device (TSD). The net effects of time-dependent properties of hardening concrete can be well incorporated in TSD due to simultaneous development of temperature and corresponding stress in restrained specimen. Moreover, experiments were ...

  • Assessment of organic micropollutants occurrence in treated wastewater using heat shock protein 47 stress responses in Chinese hamster ovary cells and GC/MS-based non-target screening

    Combining bioassays and analytical chemistry screening is a powerful approach to assess organic micropollutants which are the main contributors to toxic potential in complex mixtures of treated wastewater (TWW). The aim of this study was to perform a comprehensive toxicity assessment of treated effluents using stress response bioassays and then to assess the occurrence of the organic ...

  • Thermodynamic analysis and life cycle assessment of the heating strategies in historical buildings: a case study

    This paper presents the thermodynamic analysis and life cycle assessment (LCA) of the heating strategies in historical buildings. We evaluated two main systems used in historical buildings to provide heat: a central heating system, which is based on a method of heating the whole air volume within the building, and a localised heating system, which is based on a method of supplying the desired ...

  • Limiting metabolic rate (thermal work limit) as an index of thermal stress

    The development of a rational heat stress index called thermal work limit (TWL) is presented. TWL is deŽ ned as the limiting (or maximum) sustainable metabolic rate that euhydrated, acclimatized individuals can maintain in a speciŽ c thermal environment, within a safe deep body core temperature (< 38.20±C) and sweat rate (< 1.2 kg/hr¡1). The index has been developed using ...

  • Impact of climate change on wine production: a global overview and regional assessment in the Douro Valley of Portugal

    This paper examines the nature of climate change, viticulture and wine at the global scale and details changes and projections in the historic Douro wine region of Portugal. Overall, the observed warming over the last fifty years in wine regions worldwide has benefited some by creating more suitable conditions, while others have been challenged by increased heat and water stress. The projected ...

  • Hydration of outdoor workers in north-west Australia.

    The consequences of environmental heat stress include a reduction in safety due to impaired concentration, a decreased work capacity, and heat illness. Maintaining adequate hydration is the single most important strategy to counteract the effects of thermal stress. In this study, the hydration status of groups of outdoor workers at mine sites and related facilities was assessed. Urine specific ...

  • Hydration status of expatriate manual workers during summer in the Middle East

    Background: Implicit in all indices used for risk assessment in the prevention of heat stress is the assumption that workers arc healthy and well hydrated; studies in Australian mine workers have shown that this is not the case. Where workers arc poorly hydrated, the level of protection offered by management strategies based primarily on environmental monitoring is compromised. ...

  • OSHwiki article in the spotlight – Accident prevention in food and beverage service sector

    As the weather heats up across Europe for the summer, the HORECA industry expands with extra staff employed in hotels, restaurants and cafés across the continent in our favourite holiday destinations. But it’s important to remember that the sector faces its own set of hazards and risks. A newly posted OSHwiki article ...

  • China’s response to air pollution poses threat to water

    Record-setting levels of smog this week shut down Harbin, a city of 11 million people in northeast China. Officials blamed increased coal consumption during the first days of winter heating, underscoring the urgency of the China State Council’s ...

  • Adapting to climate change

    This assessment addresses climate change vulnerabilities and adaptation (1). Global climate observations, science and physical impacts as well as mitigation — the reduction of greenhouse gas (GHG) emissions — are covered in separate analyses (2). To achieve the EU's objective of limiting the global temperature increase to 2 °C above pre-industrial levels, global GHG emissions need ...

  • Three ways to strengthen IPCC reports

    As the UN’s COP 21 meeting in Paris, France, draws closer, the future of the Intergovernmental Panel on Climate Change (IPCC) is under consideration. In numerous consultations from Nairobi to Berlin, member countries and scientists are discussing what’s next for the body whose scientific assessments have underpinned the UN ...

  • The connection between climate change and recent extreme weather events

    What do we know about the connection between climate change and recent extreme weather events, such as the heat waves, drought, and fires? Scientists agree that climate change has already primed the pump for extreme weather events: A recent report by National Oceanic and Atmospheric Administration (NOAA) scientists compared the rising risk of extreme weather events to a baseball ...

  • A civilizational tipping point

    In recent years there has been a growing concern over thresholds or tipping points in nature. For example, scientists worry about when the shrinking population of an endangered species will fall to a point from which it cannot recover. Marine biologists are concerned about the point where overfishing will trigger the collapse of a fishery. We know there were social tipping points in earlier ...

  • Downstream Voices - Wetland Solutions to Reducing Disaster Risk

    Until recently, the world’s response to inevitable climate change was based on producing ever more precise forecasts of what would happen locally – running ever more sophisticated climate models to generate data on the climate in Bamako, Mali in 2040, for instance – and then working out how to “adapt” to the change. While ever bigger super-computers with ever more ...

  • The Southwest’s most important number

    By mapping a key indicator of droughts, pests and wildfire in arid places, scientists offer hope for spotting — and addressing — drought before it sets in. Junipers are hard to kill. Native to both warm, flooded tropics and the frigidly dry Arctic, it’s no surprise they come highly recommended for beginning landscapers. But in the ...
