  • Implementing Sensor Technology Applications for Workplace Health
    Spook et al. BMC Public Health (2019) 19:1100 https://doi.org/10.1186/s12889-019-7364-2 RESEARCHARTICLE Open Access Implementing sensor technology applications for workplace health promotion: a needs assessment among workers with physically demanding work Sander Mathijn Spook, Wendy Koolhaas, Ute Bültmann and Sandra Brouwer* Abstract Background: Workers with physically demanding work may be at risk for injury, illness or other adverse health outcomes due to exposure to different occupational hazards, especially at higher age. Sensor technology applications may be useful in the workplace to unobtrusively measure and monitor work exposures and provide workers with real- time feedback or access to data on demand. Many aspects might impede the implementation of sensor technology applications in the workplace, which should be taken into consideration for a successful implementation. Moreover, needs and preferences of workers regarding the use of sensor technology applications during work performance need to be identified. Therefore, the aim of this study was to identify worker needs and preferences regarding the use of sensor technology applications in the workplace. Methods: Four on-site focus group sessions were conducted in four different companies among workers with physically demanding work (n = 30). Semi-structured interview schedules were used to identify which work exposures should be measured, by which kind of sensor technology applications, under which (pre)conditions, how to motivate long-term use of sensor technology applications, and which type of feedback is preferred. For data analysis, a content-analysis with an inductive approach was performed. Results: Participants mentioned that they want to use wearable sensor technology applications to measure and monitor physical job demands, occupational heat stress, noise and fatigue.

  • Occupational Heat Stress Contribution to WHO Project on “Global Assessment of the Health Impacts of Climate Change”, Which Started in 2009
    ClimateCHIP = Climate Change Health Impact & Prevention: http://www.climatechip.org/ 20 December 2014 Technical Report 2014: 4 Occupational Heat Stress Contribution to WHO project on “Global assessment of the health impacts of climate change”, which started in 2009. Tord Kjellstrom, Bruno Lemke, Matthias Otto, Olivia Hyatt, Keith Dear Project carried out via Health and Environment International Trust, Mapua, New Zealand; email: [email protected] December 2014 1 Summary Increasing heat exposure during the hottest seasons of each year is the most obvious outcome of global climate change, and the issue that greenhouse gas modeling can assess in the most predictable manner. Occupational heat stress is an important direct health hazard related to climate conditions and climate change. The physiological limits of a “livable thermal environment” are well defined, but naturally, the sensitivity to heat exposure has a substantial individual variation. Modern methods of analysis make possible quantitative estimations of the impacts of current climate and future climate change: mortality, non-fatal heat stroke, heat syncope and heat exhaustion, the latter linked to work capacity loss, which is often overlooked in climate change health impact analysis. For these direct health impacts of climate change, it is the local climate where people live and work that matters. Using a field change method for three climate model data provided by WHO, estimates of the heat stress index WBGT for 60,000 grid cells around the world were produced. These estimates included monthly values for the hottest four hours and other hours of each day. Using 30-year average estimates for baseline (1960-1989), 2030 and 2050 we calculated the occupational health impacts for fatal and non-fatal heat stroke, as well as work capacity loss.

University of Nebraska Medical Center (UNMC) MPH Capstone Project: AN ASSESSMENT OF OCCUPATIONAL HEAT STRESS IN A CENTRAL UTILITY PLANT COLLEGE OF PUBLIC HEALTH UNIVERSITY OF NEBRASKA MEDICAL CENTER Abstract Global climate change has been declared a threat to human health, which includes occupational safety issues. As temperatures continue to increase, heat stress and heat-related illness are occupational safety issues that need to be better understood. Assessments of workplace heat exposures are key to implement appropriate health and safety interventions. This study attempted to assess whether workers’ perception of work environment temperature in a Central Utility Plant was associated with heat-stress prevention behaviors. Therefore, we used a questionnaire to collect Central Utility Plant employees’ demographic characteristics, data regarding their perceived work environment temperatures, and their behaviors related to preventing heat-related illness in the workplace. Fifteen questionnaires were received from the workers at two Central Utility Plants.
