Associations of Individual-Related and Job-Related Risk Factors with Nonfatal Occupational Injury in the Coal Workers of Shanxi Province: A Cross-Sectional Study

Abstract

ObjectivesTo assess the relationships between the risk factors and the incidence of nonfatal occupational injury of coal mine workers of Shanxi Province.MethodsA cross-sectional study was conducted from July 2013 to December 2013, and 4319 workers were recruited from more than 200,000 coal mine employees who are exposed to continuous potential risk of occupational injuries by using a two-stage stratified cluster sampling method. Trained interviewers having necessary medical knowledge conducted face-to-face interviews with the participants. Univariate and multivariable logistic regression models were used to estimate the odds ratio (OR) and the 95% confidence interval (CI).ResultsA total number of 3618 effective respondents were got from 4319 participants (83.77%) and the mean age of the participants was 41.5 years with the standard deviation of 8.65. Significant crude odds ratios were observed for all factors considered except for marital status, education, work duration, BMI, EPQ-RSC(P) scale and EPQ-RSC(L) scale. Results from multivariable logistic regression model showed significant adjusted odds ratios for risk factors including gender (female vs male 0.275, 0.094–0.800), age (≥55 vs ≤25yr 0.169, 0.032–0.900), work type (light physical labor vs heavy physical labor 0.504, 0.328–0.774), workplace (underground auxiliary vs underground front-line 0.595, 0.385–0.919), length of shiftwork experience (0~5yr vs no shift 2.075, 1.287–3.344 and ≥15yr vs no shift 2.076, 1.230–3.504) and EPQ-RSC(E) score (extraversion vs introversion 0.538, 0.334–0.867).ConclusionsSeveral risk factors of nonfatal occupational injury were identified including male, age, heavy physical labor, underground front-line, length of shiftwork experience and introversion. The coal mining enterprises should pay attention to controlling the hazards associated with frontline physical work. Workers’ behaviors, life styles and personality traits should also be considered, so that the enterprises could set achievable targets for workers and lessen the exposed period to the risky underground workstation.

“… 47 48 The total score for the extraversion subscale indicates introversion when it is less than 43.3, intermediate when it is from 43.3 to 56.7‚ and extraversion when it is greater than 56.7. 48 For the psychoticism subscale, tough-minded is defined as a total score greater than 56.7, intermediate is defined as a total score between 43.3 and 56.7‚ and mild is defined as a total score less than 43.3. 48 For the neuroticism subscale, a total score of less than 43.3 defines emotional stability, whereas a total score from 43.3 to 56.7 defines intermediate‚ and a total score greater than 56.7 defines emotional instability.…”

Mine Safety and Health Administration's Part 50 program does not fully capture chronic disease and injury in the Illinois mining industry

“…The risk of injury and illness in mines has been associated with several factors including smaller enterprise size, lower coal seam heights, and room and pillar mining . Employee characteristics associated with increased risk of injury and illness include younger age, shorter mine employment tenure, and work underground and at the face of the mine . Mine and miner characteristics may influence the patterns of reporting injuries and illnesses.…”

Effect of Application of Standard Operating Procedure and Work Motivation to Occupational Accident on Coal Mine Employees

“…This is due to the mining sector there are various risk factors that could cause injury, accidents, property damage, or death. In the mining industry there are several risks including fire, coal sparks, coal dust which can cause respiratory problems, noise, explosives, poisonous substances and landslides (Yan et al, 2015;Laney and Weissman, 2014;Cui et al, 2015;Mkpuma et al, 2015).…”
