19. Development of a Questionnaire to Examine Worker Risk Perception of Noise and Use of Hearing Protective Devices

ObjectivesTo study prevalence of infection in essential workers of Madrid City Council by occupation, related characteristics, use of protective devices, risk perception, and main concerns about COVID-19 during lockdown.MethodsA total of 30 231 workers were PCR tested for SARS-CoV-2 infection. Information was collected on COVID-19-related symptoms, risk factors, preventive equipment, and risk perception. The crude prevalence was calculated for infection, use of protective devices, perceived risk and main concerns. Additionally, adjusted prevalence and prevalence ratios (PR) were estimated for these variables using logistic regression models with age, gender, occupation, epidemiological week and laboratory as confounding factors.ResultsOverall prevalence of infection was 3.2% (95% CI 3.0% to 3.4%), being higher among policemen (4.4%) and bus drivers (4.2%), but lower among emergency healthcare personnel, firefighters, food market workers and burial services (<2%). Lower excess risk was observed in workers reporting occupational contact with COVID-19 cases only (PR=1.42; 95% CI 1.18 to 1.71) compared with household exposure only (PR=2.75; 95% CI 2.32 to 3.25). Infection was more frequent in symptomatic workers (PR=1.28; 95% CI 1.11 to 1.48), although 42% of detected infections were asymptomatic. Use of facial masks (78.7%) and disinfectants (86.3%) was common and associated with lower infection prevalence (PRmasks=0.68; 95% CI 0.58 to 0.79; PRdisinfectants=0.75; 95% CI 0.61 to 0.91). Over 50% of workers felt being at high risk of infection and worried about infecting others, yet only 2% considered quitting their work.ConclusionsThis surveillance system allowed for detecting and isolating SARS-CoV-2 cases among essential workers, identifying characteristics related to infection and use of protective devices, and revealing specific needs for work-safety information and psychological support.

Worker Risk

Behavioral-based safety is an important application of behavioral science that can be used to address safety problems in the construction sector. An understanding of construction worker risk-taking behavior is deemed to be a crucial basis on which concerned authorities and construction companies can develop effective safety interventions to reduce construction accidents. However, no studies have been conducted to examine the effects of safety climate, work condition, attitude toward risk, cognitive bias, and risk perception on construction worker risk-taking behavior through a quantitative approach. Accordingly, this study aims to propose a research model that explains construction worker risk-taking behavior. A total of 188 valid datasets were obtained through a series of questionnaire surveys conducted in representative construction projects in Hong Kong. Confirmatory factor analysis with structural equation modeling was adopted to validate the hypothesized research model. Results show that attitudes toward risk and cognitive bias have a positive influence, whereas risk perception and work conditions have a negative influence on construction worker risk-taking behavior. In addition, safety climate was negatively correlated with construction worker risk-taking behavior. Practical recommendations for reducing construction worker risk-taking behavior are also discussed in this paper.

The Relationship

Introduction: Having a clear understanding of the relationship between risk perception, knowledge, and protective behaviors could play a significant role in occupational risk management. This study aimed to survey the relationship between risk perception and knowledge on the behavior of using respiratory protection equipment in the four National Oil Products Distribution Company. Materials and Methods: In this descriptive cross-sectional study conducted in 2018, 52 workers from the loading and quality control departments of 4 national companies distributing petroleum products in Sabzevar, Bojnourd, Torbat Heydariyeh, and Shahroud participated. Data were collected through a researcher-made questionnaire whose validity and reliability were assessed (CVI: 0.9 and CVR: 0.92 and Cronbach's alpha coefficient was determined to be 0.73), and data were analyzed using SPSS19 software, and descriptive statistics and linear regression were analyzed. Results: More than half of the participants, who were exposed to the chemicals, use RPDs (Respiratory Protective Devices) all the time and when they are exposed to chemicals. While 75% of them reported using RPDs (Respiratory Protective Devices), reduces the quality of their work. In this study, there was not any significant relationship between RPDs behavior with knowledge and risk perception (P > 0.05). However, the association between work experience and RPDs was negatively significant (p= 0.009). Conclusion: The results of this study suggested that only education and knowledge could not promote individual risk perception, improving protective behavior, therefore other barriers such as uncomfortably of RPDs, or their interference with the worker should be considered. To achieve this goal, the safety and health officials of the companies must pay attention to its quality in addition to the correct choice of these devices.
