Face masks represent an effective COVID-19 mitigation strategy; this study investigated the quality in use of FFP2 masks in a group of 156 frontline HCWs recruited through a snowball procedure in northwest Italy. Participants filled out an online questionnaire (January 2022) on FFP2 sources of discomfort, physical disturbance at different anatomical points and suggestions for improvement. Most of the participants (69%) reported a feeling of protection and safety, but they also reported episodes of dyspnea (70%). The majority of glasses wearers (62%) reported fogging and displacement of their glasses. Humidity and heat were the main discomfort sources (39%), followed by elastic bands (32%). Physical disturbances were frequent and heavier on the ears, nose and cheekbones. Nursing aides and nurses perceived significantly more discomfort compared to doctors and nursing aides had the highest rate of physical disturbance. To address these issues, following participants' suggestions, FFP2 masks should be redesigned to be more adjustable, with different sizes and softer fabrics. The investigation pointed out criticalities in the use of FFP2 masks related to different professional roles within the overall group of HCWs and stressed the need for an FFP2 human-centered design that accounts not only for physical needs but also for workload and task variability.

Objectives: Safety pictograms are important graphic elements that are useful for rapidly conveying messages in workplaces. The purpose of this study was to investigate the comprehension of safety pictograms affixed to agricultural machinery among a group of Pakistani migrant farmworkers employed in Italy. Methods: Interviews about the meanings attributed to four standardized safety pictograms affixed to agricultural machinery depicting the most frequent causes of farm accidents were administered to 29 Pakistani migrant farmworkers employed on Italian farms. Results: There was high variability in pictogram comprehension. None of the participants interpreted all the pictograms in accordance with the definitions provided by the international standards. Higher comprehension rates were reported for pictograms related to the risks of tractor rollover and foot injury, while pictograms referring to the need to consult a technical manual and the risk of entanglement yielded lower comprehension scores. Previous farming experience in the country of origin and the number of years of education were significantly associated with comprehension scores. Conclusion: A discussion of pictogram features that may be critical for comprehension is provided, and (re)design suggestions are given to improve the cross-cultural comprehension of these safety signs.

Objective: To identify the critical behaviors that may hinder the correct use of foldable rollover protective structures (FROPS) on tractors and to explore the influence of user factors and FROPS technical characteristics.Background: FROPS are effective in preventing fatal injuries in rollover accidents if they are in the upright position. However, many farmers leave FROPS folded down.Method: Twenty farmers and sixteen models of tractors were involved in the study. Operators were observed while raising the FROPS, and the observed behaviors were correlated with user factors and FROPS technical features.Results: In the initial rotation of the FROPS, higher lowered roll-bar to ground distance and FROPS pivot-pin to ground distance required more awkward and unbalanced postures (p = .02 and p = .01, respectively). When rotating the FROPS in upright position, smaller stature of the participants and higher FROPS pivot-pin to ground distance were significantly correlated with using the tractor's rear 3-point lower links as a supporting surface (p = .01 and p = .02, respectively).Conclusion: FROPS might be revised considering users' comfort in use and anthropometric variability, to improve reachability, avoid risky behaviors, and enhance FROPS operation.Application: Technical solutions to enhance FROPS accessibility may be developed, particularly by providing safe surfaces to support operators and highlighting the grasping points. Further best practices and information on correct gestures to handle the FROPS should be included in the tractor manual. [ABSTRACT FROM AUTHOR]
