“…Of course, the human eye has adaptive skills and can adapt the eye to the conditions prevailing at a given moment and specific conditions. The accuracy of the visual work is assessed in the so-called vision functions that occur as eye contrast sensitivity, visual acuity, perception speed (Reese, 2018;Liao Pin-Chao et al, 2021) The high level of industrialization of the modern world means that people are more and more often exposed to contact with hazardous substances and chemical preparations both in the work environment and outside it. They cause many diseases, especially of the respiratory system, but also dermatitis, psychoneurological disorders and cancer (Kapustka et al, 2020).…”

The article presents the element of occupational health and safety management in enterprises, with particular emphasis on the identification of occupational hazards. The factors that may be a source of occupational hazards have been classified and divided. The aim of this study was to assess the impact of occupational hazards on work safety in the opinion of employees of micro and small enterprises. The research was carried out using the proprietary questionnaire. The results were verified by means of a direct interview with elements of observation. The research was compared with the trends prevailing in the enterprises of the European Union countries according to the results of the research conducted by EU-OSHA. Polish respondents considered physical and psychophysical factors to be the main occupational hazards. The results turned out to be very similar to those presented by EU-OSHA in its publicly available reports. The basic principle of occupational health and safety management, i.e. identification of occupational hazards, is reliability and correctness. Identification of occupational hazards gives the opportunity to take correct and effective corrective and preventive actions reducing occupational risk, for example through the effective use of personal protective equipment, or a more detailed treatment of both introductory and instructional training. The article also highlights the migration of individual occupational hazards, which depends on many factors, both professional and non-professional.

“…Hazard recognition is the first step to prevent accidents [1]. In recent years, computer vision-based construction hazard recognition (CHR) technology has attracted widespread interest of researchers [2], such as identifying and tracking physical elements (including temporary structures, machine and materials, etc.)…”

“…The nature of the visual search process is an important and typical physiological activity for hazard recognition [11]. Previous studies have tried to characterize the visual patterns during CHR through a series of eye-movement indicators [1]. Among them, the most commonly used are area-of-interest (AOI)-based indicators such as fixation times [12], duration of fixation [13] and fixation space density [14].…”

“…The research objectives are (1) to design and conduct an eye-tracking experiment with real construction scenes pictures as the CHR experimental background to document the participants' visual sequences during their CHR processes; (2) to introduce TQCA method with the analytical capability for temporality which allows for the inclusion of sequence conditions, and apply it in the visual sequences analysis to identify the visual patterns for CHR; (3) to interpret the visual patterns from both quantitative and qualitative perspectives and explore the visual cognitive strategies of CHR implied by these visual patterns. Further, the practical contributions of the findings to computer vision and safety training for CHR as well as the theoretical contributions to visual cognitive psychology theories are discussed.…”

Visual cognitive strategies in construction hazard recognition (CHR) signifies prominent value for the development of CHR computer vision techniques and safety training. Nonetheless, most studies are based on either sparse fixations or cross-sectional (accumulative) statistics, which lack consideration of temporality and yielding limited visual pattern information. This research aims to investigate the temporal visual search patterns for CHR and the cognitive strategies they imply. An experimental study was designed to simulate CHR and document participants’ visual behavior. Temporal qualitative comparative analysis (TQCA) was applied to analyze the CHR visual sequences. The results were triangulated based on post-event interviews and show that: (1) In the potential electrical contact hazards, the intersection of the energy-releasing source and wire that reflected their interaction is the cognitively driven visual area that participants tend to prioritize; (2) in the PPE-related hazards, two different visual strategies, i.e., “scene-related” and “norm-guided”, can usually be generalized according to the participants’ visual cognitive logic, corresponding to the bottom-up (experience oriented) and top-down (safety knowledge oriented) cognitive models. This paper extended recognition-by-components (RBC) model and gestalt model as well as providing feasible practical guide for safety trainings and theoretical foundations of computer vision techniques for CHR.

Accurate comprehension of safety signs plays a critical part in warning construction workers of potential work hazards. However, existing studies have rarely investigated construction workers' comprehension of safety signs at construction sites. Moreover, existing evaluation methods are generally based on subjective behavior tests, questionnaires, and interviews. Therefore, this study examined the effects of semantic congruity on the comprehension of safety signs, including two sign types (prohibition vs. warning signs) and two conditions (semantic congruence vs. incongruence), combining event‐related potentials and time‐frequency analysis measurements. Adopting the S1‐S2 paradigm, electroencephalogram data were recorded when participants decided whether S1 and S2 were semantically congruent or not. Results showed that the semantically incongruent safety sign‐word pairs elicited larger N400 amplitudes and increased theta (3–8 Hz) power in 300–420 ms. The amplitude of N400 in the semantically incongruent condition of the warning sign‐word pairs was more negative than that for the prohibition sign‐word pairs, while there were no significant differences between the prohibition and warning sign‐word pairs in the semantically congruent condition. A greater late positive potential (LPP) (550–750 ms) was also elicited in the semantically incongruent safety sign‐word pairs, which was different from previous studies that observed larger LPP in congruent conditions. These results suggest complicated cognitive mechanisms of safety sign comprehension in construction workers. This study extends safety sign comprehension research by using electrophysiological approaches and provides useful indicators for researchers or safety engineers to measure the semantic congruity of proposed sign designs.
