Abstract

In the present study, a survey on subjective symptoms and hot prevention measures in summer was conducted in 204 male traffic control workers and 115 male construction workers. Work loads of traffic control workers and construction workers were estimated at RMR 1-2 and RMR 2-4, respectively. A self-administered questionnaire was used to collect information on age, occupational career, working habit, present or past history of diseases, individual preventive measures to the heat, and subjective symptoms in the summer. Daily working hours in the sunshine of the traffic control workers were significantly longer than those of the construction workers. Prevalence rates of changing clothes frequently, avoiding direct exposure of face and neck to sunlight using towel like materials, and wearing sunglasses in the traffic control workers were significantly lower than the construction workers. Prevalence rates of symptoms in the upper extremities in the traffic control workers were significantly lower than those in the construction workers. Prevalence of work difficulty due to hot weather during work in the traffic control workers was significantly lower than the construction workers. On the basis of the results obtained, some preventive countermeasures to improve working environment are presented.

  • At the global level, our findings are consistent with the level of summer heat exposure (hourly mean WBGT values) reported at outdoor construction sites in other studies in tropical and subtropical countries.

    “At the global level, our findings are consistent with the level of summer heat exposure (hourly mean WBGT values) reported at outdoor construction sites in other studies in tropical and subtropical countries (Kähkönen et al., 1992; Inaba and Mirbod, 2007; Miller and Bates, 2007; Maiti, 2008; Pérez-Alonso et al., 2011; Rowlinson and Jia, 2014; Venugopal et al., 2016).”
  • Cases of these acute health effects are well-documented among workers in construction jobs.

    “Cases of these acute health effects are well-documented among workers in construction jobs (Inaba and Mirbod, 2007; Miller and Bates, 2007; Horie, 2013; Montazer et al., 2013; Dutta et al., 2015; Gubernot et al., 2015; Jia et al., 2016; El-Shafei et al., 2018).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
