Opis:
Globalization and trade among developed and developing countries has increased the need of risk communication at the workplace. The purpose of this study was to examine differences in risk communication and perception in various countries. It looked at hazard perception associated with colors and safety words among Indian industry workers. Fifty workers participated in the study focused on hazard rating of 9 safety words and 7 colors. In one part of the study the participants were asked to associate colors with safety words through recalling them from their long-term memory; in another they were asked to associate safety words with given colors. The results showed that certain words and colors implied different hazard rating at the workplace. The rank ordering of safety words and colors varied significantly in different countries. Hence population factors should be taken into consideration when designing standards for hazard communication.

Opis:
This paper aims to help enhance the process of risk identification and assessment in small enterprises by facilitating the incorporation of insights from accident, human error and risk perception models. This effort takes place through grouping and classification models of all these aspects according to certain criteria, to fit the proper set of models to each situation. To further facilitate the process, the main guidelines of each model are presented. The whole approach is not a new theoretical model but a simplified presentation to help safety engineers in selecting the proper model for the workplace to better assess its risks. An example of the application of this approach is also presented.

Opis:
The physiological properties of clothing designed to provide protection against cold, windy and damp conditions affect comfort. The weight, thickness, stiffness of the fabrics and friction between the clothing layers affect physical performance. The comfort and perception of performance associated with 3 military winter combat clothing systems from different decades (the new M05 system, the previous M91 system and traditional clothing) were observed during a winter military manoeuvre. Subjective experiences concerning comfort and performance were recorded for 319 subjects using questionnaires. The most challenging conditions for comfort and performance were perspiration in the cold and external moisture. The new M05 system provided warmer thermal sensations (p < .010), dryer moisture sensations in the presence of external dampness (p < .001), dryer perspiration moisture sensations (p < .050) and better perception of physical (p < .001) and mental performance (p < .001) than the other systems. Careful development of the clothing system guarantees good comfort and performance during cold exposure.

Opis:
In UK’s construction industry, site dumpers cause more serious accidents than in any other type of construction plant. Previous research has indicated that driver behaviour plays a pivotal role in the vast majority of these accidents. Using a mental models-based approach, 20 dumper drivers were interviewed with regard to the process by which several typical types of accident occurred. It was found that drivers were generally well-informed about the hazards of driving dumpers on a construction site. However, the findings also exposed some critical knowledge gaps, which could increase a driver’s chances of an accident. Educational material relating to these knowledge deficiencies could easily be prepared and incorporated into revised construction information leaflets or driver training courses.

Opis:
This article presents the results of laboratory tests on the combined effect of whole-body vibration (WBV) and hand–arm vibration (HAV). The reactions of subjects exposed to various combinations of vibration were recorded. The vibrotactile perception threshold (VPT) test identified changes caused by exposure to vibration. Ten male subjects met the criteria of the study. There were 4 series of tests: a reference test and tests after exposure to HAV, WBV, and after simultaneous exposure to HAV and WBV. An analysis of the results (6000 ascending and descending VPTs) showed that the changes in VPTs were greatest after simultaneous exposure to both kinds of vibration. The increase in VPT, for all stimulus frequencies, was then higher than after exposure to HAV or WBV only.

Opis:
In the UK construction site dumpers cause more serious accidents than any other type of construction plant. Previous research has indicated that driver behavior plays a pivotal role in the vast majority of these accidents. This study used a paired comparison technique to explore dumper drivers’ and subject matter experts’ (SMEs’) risk perception and its relationship to risk-taking behavior. It was found that driver risk perception significantly differed from measures of “objective risk”, derived from accident data and also from SMEs’ risk perception. Furthermore, drivers still engaged in undertaking perceived high risk behaviors. The results suggest that driver risk perception was linked to the “perceived dread” of an accident, rather than its likelihood and that risk-taking behavior was often driven by situational factors, such as site safety rules or the behavior of other personnel on the site, together with an overarching culture that prioritizes production over safety.

Opis:
Measurements 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.

Opis:
A lot of attention has been focused on workers’ perceptions of workplace safety but relatively little or no research has been done on the impact of job satisfaction on safety climate. This study investigated this relationship. It also examined the relationships between job satisfaction and workers’ compliance with safety management policies and accident frequency. A positive association was found between job satisfaction and safety climate. Workers who expressed more satisfaction at their posts had positive perceptions of safety climate. Correspondingly, they were more committed to safety management policies and consequently registered a lower rate of accident involvement. The results were thus consistent with the notion that workers’ positive perceptions of organizational climate influence their perceptions of safety at the workplace. The findings, which have implications in the work environment, are discussed.

Opis:
Thai food industry employs a massive number of skilled and unskilled workers. This may result in an industry with high incidences and accident rates. To improve safety and reduce the accident figures, this paper investigates factors influencing safety implementation in small, medium, and large food companies in Thailand. Five factors, i.e., management commitment, stakeholders’ role, safety information and communication, supportive environment, and risk, are found important in helping to improve safety implementation. The statistical analyses also reveal that small, medium, and large food companies hold similar opinions on the risk factor, but bear different perceptions on the other 4 factors. It is also found that to improve safety implementation, the perceptions of safety goals, communication, feedback, safety resources, and supervision should be aligned in small, medium, and large companies.

Opis:
The study aimed at verifying a hypothesis that supporting a visual signal of regulation deviation with an auditory one could improve the quality of regulation; the operator would have better information on machine operation. A special simulator was applied to follow-up tracking with a manual lever which controlled vertical movements of a cursor on a monitor screen. Simultaneously with visual information on screen, the operator was provided with an auditory deviation signal of pre-determined characteristics. 33 young males underwent the test. It was found that supporting a visual signal with an auditory one resulted in an improvement in the regulation quality by 5–6%, which proved synergy between those signals. The results may be used in designing tele- and servo-mechanisms, especially for remote control machinery, e.g., inspection robots or micromanipulators controlled by operators in a follow-up system.

Opis:
A methodology was developed for diagnosing industrial work, which includes questionnaire, observation, measurements, data collection and statistical analysis. A survey was conducted to investigate the relationship between job satisfaction and factors that affect work design in 2 automotives manufacturing companies in Malaysia. A basic work design model was proposed. The aim of this model was to determine the factors that influence employees’ perception towards their work. A set of multiple-choice questionnaires was developed and data was collected by interviewing employees at a production plant. The survey focused on job and environmental factors. The results supported the proposed model and showed that job and environmental factors were significantly related to job satisfaction. They highlighted the significant influence of age, work experience and marital status on job satisfaction. Further, environmental factors, especially the surroundings, context dependence and the building’s function, also had a significant impact on job satisfaction.

Opis:
The main objective of this study was to evaluate different scales of perceived strain during the performance of various physical tasks. A total of 52 male and female participants took part in 4 experiments to achieve the study objective. The results suggest that a bipolar comfort-discomfort scale is a more appropriate instrument than a discomfort scale for assessing cumulative physical stresses at work, especially at the beginning of the shift. For assessing discomfort at the end of the work shift, a unipolar scale may also be used. On the basis of the obtained results, red, green, and yellow zones are suggested to establish priorities for work redesign efforts in ergonomic control programs.
