Heat Strain and Hydration Status of Surface Mine Blast Crew Workers
Objective: Dehydration and symptoms of heat illness are common among the surface mining workforce. This investigation aimed to determine whether heat strain and hydration status exceeded recommended limits. Methods: Fifteen blast crew personnel operating in the tropics were monitored across a 12-hour shift. Heart rate, core body temperature, and urine-specific gravity were continuously recorded. Participants self-reported fluid consumption and completed a heat illness symptom inventory. Results: Core body temperature averaged 37.46 ± 0.13°C, with the group maximum 37.98 ± 0.19°C...
Occupational Heat Strain in a Hot Underground Metal Mine
Objective: In a hot underground metal mine, this study evaluated the relationship between job task, physical body type, work shift, and heat strain. Methods: Thirty-one miners were evaluated during 98 shifts while performing deep shaft-sinking tasks. Continuous core body temperature, heart rate, pre- and postshift urine specific gravity (USG), and body mass index were measured. Results: Cutting and welding tasks were associated with significantly (P < 0.05) increased core body temperature, maximum heart rate, and increased postshift urine specific gravity. Miners in the obese level II and III...
Occupation and environmental heat-associated deaths in Maricopa County, Arizona: a case-control study
Background Prior research shows that work in agriculture and construction/extraction occupations increases the risk of environmental heat-associated death. Purpose To assess the risk of environmental heat-associated death by occupation. Methods This was a case-control study. Cases were heat-caused and heat-related deaths occurring from May-October during the period 2002–2009 in Maricopa County, Arizona. Controls were selected at random from non-heat-associated deaths during the same period in Maricopa County. Information on occupation, age, sex, and race-ethnicity was obtained from death...
Radiation Sources in Natural Gas Well Activities
More attention and monitoring of occupational radiation exposure in the natural gas industry are warranted . The boom in the natural gas industry across the nation, made possible by recent advances in hydraulic fracturing ("fracking") methodology, has resulted in increased concern for public and environmental safety. This, in turn, has resulted in a series of recommendations for minimizing the risk to the public and the environment (Secretary of Energy, 2011). The natural gas industry has responded to environmental concerns by cleaning and recycling frack water, which can take the form...
Shale gas extraction in the UK: A review of hydraulic fracturing
The health, safety and environmental risks associated with hydraulic fracturing (often termed 'fracking') as a means to extract shale gas can be managed effectively in the UK as long as operational best practices are implemented and enforced through regulation. Source : Source :
