Occupational health and safety allows the prevention of occupational diseases and accidents. Agriculture is one of the sectors in which it is important to prevent the musculoskeletal disorders that workers usually develop. The objective of this study is the evaluation of postures adopted by courgette farmers in greenhouses of the Almeria-type. OWAS (Ovako Working Posture Assessment System), an ergonomic evaluation method, is used and applied after making observations to the postures adopted by the workers who were previously video recorded. The results concluded that the four risk levels established by OWAS appeared, with 37.14% being the highest rate and belonging to risk level 2, 33.33% to risk level 1, 28.57% to risk level 3, and 0.95% to risk level 4. Therefore, depending on the severity of the postures adopted in each task, the need for changes in a short, medium, or long period of time was concluded.

Biosafety Level 2

Heightened interest in pathogens with the potential for aerosol transmission and for which prevention and medical treatment is not readily available has resulted in a need for more work environments that meet Biosafety Level 3 (BSL 3) criteria. Recognizing that the facility-based criteria for BSL 3 cannot be achieved by some existing laboratories, the Centers for Disease Control and Prevention (CDC) and National Institutes of Health (NIH) biological safety guidelines provide an option for attaining BSL 3 status through the use of Biosafety Level 2 (BSL 2) facilities and strict adherence to BSL 3 practices (BSL 2/3). Inherent to this provision is a greater emphasis on safe work practices. Since the extent to which this approach is actually used in practice is not known, a nationwide mail survey of medical academic and research institutions was conducted to provide an objective indication of the proportion of BSL 3 operations actually being carried out in the BSL 2/3 mode. The results obtained indicate that 2% of activities designated as BSL 3 in the study population actually achieve this level of protection using the BSL 2/3 approach. The findings quantitatively estimate for the first time the proportion of BSL 3 activities being carried out in this fashion, and can serve as a reference point for future studies to evaluate usage trends. The results also demonstrate the utility of flexible, performance-based health and safety guidelines, as a significant amount of clinical and research work is being accommodated with the BSL 2/3 provision.

Trading regulatory risk arises prominently in the preliminary formulation of a unified and interconnected electricity market in China. Risk indices, evaluation models and methods as well as index weights are three important aspects of a comprehensive trading regulatory risk evaluation. In this paper, firstly, on the basis of the current electricity market environment in China, systematic trading regulatory risk indices used to quantify the risk level of the unified and interconnected electricity market are established. Secondly, evaluation models and a evaluation method of the trading regulatory risk are developed on the basis of synthesis of fuzzy inference and analytic hierarchy process (AHP). The fuzzy set approach is employed to identify the membership degree of each index to various risk levels, while the AHP is used to acquire the weights of the proposed trading regulatory risk indices. Finally, a simulation based case study on the trading regulatory risk evaluation is presented to illustrate the effectiveness of the proposed indices and the evaluation method.

This study conducted an ergonomic evaluation of the working posture of workers engaged in various processes in the packaging section of a food manufacturing company. Workers in the packaging section of the food manufacturing company were divided into operating, folding, packing, carton wrapping and palletizing. Forty of the workers in the packaging section were placed under observation through video recording of their daily activities for a period of three months to obtain their working postures. Rapid Upper Limb Assessment (RULA) was used to analyze the working postures in order to obtain their ergonomic risk levels. Computer codes for RULA were written for quick and easy evaluation of upper arm, lower arm, wrist, wrist twist, neck, trunk and leg postures. The results from RULA indicated that 25% of the workers in the operating and folding units were exposed to medium ergonomic risk level; 30% of the workers in the packing unit and 10% of the workers in the carton wrapping unit were exposed to high ergonomic risk level while 10% of the workers in the palletizing unit were exposed to a very high ergonomic risk level. The study concluded that workers in the packaging section of the food manufacturing company were exposed to between medium and very high ergonomic risk levels of working posture necessitating the need to change the conditions of their workstations.

Slouching and squatting work postures in the fish cleaning process can cause skeletal muscle injury. Based on the results of previous research conducted by Adelia (2020), the results of the existing NBM show that workers have complaints in the muscles of the neck, arms, back, waist, buttocks, hands, wrists, thighs, knees, and feet. The result of total muscle complaints individual skeletal is 75, meaning that the existing work posture requires work improvement. Improvement of working posture can be done by designing work aids in the form of desks and chairs. The determination of the MSDs risk level category was carried out by identifying the skeletal muscle complaints felt by workers using a Nordic body map (NBM) questionnaire, a working posture assessment was carried out to determine the score level in work posture using the Rapid Upper Limb Assessment (RULA) method with the help of CATIA V5R20 software. Assistive devices in the form of desks and work chairs are designed based on complaints experienced by workers and use the anthropometric approach in determining the dimensions of work aids. Based on the results of the implementation of work aids, there was a change in the score for skeletal muscle complaints and work posture. The results showed that the average NBM value of individual muscle complaints was 56.75, this is included in the moderate risk level and the results of the RULA analysis on the repair work posture experienced a change in the final score, namely 4 (yellow).

Health and safety at work directly influence the development of sustainable agriculture. In the agricultural sector, many farm workers suffer musculoskeletal disorders caused by forced posture. The objective of this research is to assess working postures during melon cultivation in Almería-type greenhouses. The Ovako Working Posture Assessment System (OWAS) has been used with pictures of the tasks. The variables studied by multiple correspondence analysis were as follows: Subtask, Posture code, Back, Arms, Legs, Load, Risk, and Risk combination. The OWAS analysis showed that 47.57% of the postures were assessed as risk category 2, 14.32% as risk category 3, 0.47% as risk category 4, and the rest as risk category 1. Corrective measures should be implemented immediately, as soon as possible, or in the near future, depending on the risks detected.

Hyperspectral Camera

Using a calibrated hyperspectral camera, we evaluated the hazard risk level of blue light illumination using the IEC TR 62778:2014 method. The risk levels obtained using the hyperspectral camera were compared with those obtained using the method described in the IEC 62471:2006 guidelines. The IEC TR 62778:2014 risk level of each test product was the same as that obtained using the IEC 62471:2006 method. Compared with the evaluation method implemented using a conventional single-point measurement, our approach using a hyperspectral camera obtained spectral radiance measurements in a much shorter time, of the order of several seconds, via two-dimensional measurements.

Rapid Entire Body Assessment

Determining the potential risks of musculoskeletal disorders through working postures in a workplace is expensive and time-consuming. A novel intelligent rapid entire body assessment (REBA) system based on convolutional pose machines (CPM), entitled the Quick Capture system, was applied to determine the risk levels. The aim of the study was to validate the feasibility and reliability of the CPM-based REBA system through a simulation experiment. The reliability was calculated from the differences of motion angles between the CPM-based REBA and a motion capture system. Results show the data collected by the Quick Capture system were consistent with those of the motion capture system; the average of root mean squared error (RMSE) was 4.77 and the average of Spearman’s rho (ρ) correlation coefficient in the different 12 postures was 0.915. For feasibility evaluation, the linear weighted Cohen’s kappa between the REBA score obtained by the Quick Capture system and those from the three experts were used. The result shows good agreement, with an average proportion agreement index (P0) of 0.952 and kappa of 0.738. The Quick Capture system does not only accurately analyze working posture, but also accurately determines risk level of musculoskeletal disorders. This study suggested that the Quick Capture system could be applied for a rapid and real-time on-site assessment.
