A Comparative Study of Objective and Subjective Assessment of Occupational Risk

Abstract

Measurement of dangerous, harmful and annoying factors in the working environment are used to assess occupational risk. Surveys on workers' subjective perception of risk are used, too. This study aimed to compare subjective assessment of work-related factors with their objective measurements and a national database on occupational risk. Spearman's correlation analysis, stepwise regression analysis and structural modelling were used to determine the relationship between subjective and objective risk assessment and to acquire knowledge about the role of psychosocial job characteristics as predictors of subjective assessment. Subjective assessment of hazards was related not only to their objective measurements but also to psychosocial job characteristics, workers' individual characteristics and work load. Even though subjective and objective assessments of hazard are strongly related, they are distinct phenomena. Hence, risk assessment should be carried out with both objective and subjective methods.

Noise Pollution in Metalwork and Woodwork Industries in the Kingdom of Saudi Arabia

“…In developing countries, there has been a great concern about the magnitude of industrial noise, particularly in the textile industry in Egypt, India, China, Thailand and Tanzania [1], and in metalwork and woodwork industries in the USSR/Russia [35,36], Bulgaria [37], the Czech Republic and Slovakia [38], Poland [39,40,41,42], Turkey [43,44], Cyprus [45], Portugal [46], India [47,48,49,50,51], Pakistan [52], Malaysia, Thailand, Indonesia and Vietnam [53,54,55], Korea [56], Hong Kong [57], Singapore [58], Iran [59], Kuwait [60] and Ghana [61].…”

Analyzing the Effect of Brexit on the British Construction Industry Using Fuzzy Sets Theory

“…This is driven by the fact that risk analysis, including the techniques used, entail subjectivity. With risk, there is uncertainty and need for judgement, and hence risk analysis retains considerable scope for inaccuracy and bias (Howarth, 2007;Koradecka et al, 2010;Boholm and Corvellec, 2011). Conducting a risk analysis to inform decisions associated with the outcomes of Brexit is no different, because the results obtained by pro-Brexit analysts are unlikely to be the same as those obtained by anti-Brexit analysts, despite both having access to the same information.…”

Understanding the synthesis of anthropometric diversity and workspace dimensions in ergonomic design of light armored vehicle

“…The ergonomic compatibility assessment is an iterative process that typically involves two ways of evaluation: subjective and objective (Kolich & Taboun, 2004). Subjective evaluation is not always preferable because of its higher cost, completion time, error‐rates (Tan et al, 2008), and risky environments (Koradecka et al, 2010; Singh, 2019), and is susceptible to biased results due to of the influence of personal preferences (Annett, 2002; Singh et al, 2019). Therefore, an objective evaluation was conducted in this study.…”
