Objectives: To analyze the effect of personal protective equipment training on new hospital infection managers. Methods: Personnel are divided into two batches by region. Adopt a diversified training model to train all personnel, finally conduct practical assessments and issue certificates. Collect information through information technology, analyze questionnaires, and understand trainees’ circumstances before and after the training. Each training batch has uniform teachers and the same training methods. Results: After the training, the trainees' proficiency in putting on and taking off protective equipment increased by 22.85%, and ability to choose protective equipment according to different working environments increased by 22.04%; 78.23% trainees believed that practical exercises should be emphasized. Taking off protective clothing was considered as the most difficult link in practical training (91.13%), followed by putting on protective clothing (70.43%). 96.24% trainees believed that this training is helpful for future work. Conclusions: It is quite necessary to implement personal protective equipment training among new hospital infection managers; where, practical training, assessment, information-based questionnaire survey, expert theory teaching have achieved good results; the training helps reduce occupational exposure-induced hospital infection, and at the same time, avoids improper use of protective materials and waste.

Background. Eye injuries are one of the most common work-related injuries among certain occupations, including welders. The aim of this study was to determine the prevalence and factors influencing eye injuries among welders in Accra, Ghana. Methods. In a cross-sectional study, we recruited 382 welders in Accra from two welding sites. Systematic sampling was used to select participants. A pretested semistructured questionnaire was used to collect demographic information, history of eye injuries, ownership, and use of eye protective equipment and workplace characteristics. Bivariate and multivariate logistic regressions at 5% level of significance were used to determine factors influencing eye injuries. Data were entered into Microsoft excel and exported to Stata 16/MP for analysis. Results. We found 59.7% of welders engaged in electric/arc welding and 40.3% in gas welding. Overall prevalence of eye injuries was 47.9%, higher among electric/arc welders (73.7%) compared to gas welders (9.7%). Factors associated with eye injuries were engaging in gas welding [AOR: 0.08, 95% CI: 0.04–0.16], higher monthly income [AOR = 5.26; 95% CI: 1.72–16.09], nonuse of eye PPE while working [AOR = 1.86; 95% CI: 1.02–3.43], and no training on the use of eye personal protective equipment [AOR = 2.17; 95% CI: 1.07–4.38]. Conclusion. There is high prevalence of welding-related eye injuries among electric welders. Gas welding, high monthly income, nonuse of eye protective equipment, and inadequate training on the use of eye protective equipment were significantly associated with eye injuries. Health policies should be implemented to ensure all welders use eye personal protective equipment.

The Covid-19 pandemic has had a significant impact on the environment. The enormous need for personal protective equipment (PPE) masks (both medical and non-medical masks), protective clothing, face shields, gloves to hand sanitizers and disinfectants has resulted in the accumulation of medical waste in some regions in Indonesia. This paper aims to describe the environmental diplomacy and international cooperation efforts undertaken by the Indonesian government to address these problems. The author finds that Indonesia's environmental diplomacy was carried out before the pandemic occurred, but not much has focused on medical waste management. International cooperation to overcome the problem of medical waste accumulation has been carried out with some countries such as Japan, ASEAN and also WHO. Of course, considering that this pandemic is still ongoing, it is hoped that this paper can be the start of research and can be used as a stepping stone for further research.

Wearing appropriate personal protective equipment during the application of pesticides is one method of reducing dermal exposure to pesticides. Thus, the aim of this research is to develop personal protective clothing (PPC) coated with gum rosin and investigate the efficiency of its level of protection against chlorpyrifos and cypermethrin. Comparison of the protection efficiency of each PPC with Tychem® C coveralls was also investigated. Five commercially available cotton fabrics were chosen for tailoring the PPC, and then, the PPC was coated with a gum rosin finish to provide water repellence. The efficiency of the level of protection of the gum rosin-coated PPC against insecticides was tested in a laboratory (closed chamber). The remarkable findings were that the % protection efficiencies for all the PPC, with the exception of one, were not significantly different to those for Tychem® C coveralls. The protection efficiencies ranged from 99.85% to 99.97% against chlorpyrifos and 99.11% to 99.89% against cypermethrin. Therefore, our results suggest that gum rosin-coated clothing provided satisfactory levels of protection against insecticides and could be considered as suitable protective clothing for pesticide applicators. Choice of an appropriate fabric for coating with gum rosin also needs to be considered. A further study in field conditions is warranted to confirm the protection efficiency in a working environment.

AbstractGraphene is a new, advanced material with many possible applications in basic and clinical medicine, electronics and automation. Graphene compounds can be successfully used as an integral part of drug delivery systems, in the construction of transistors, polar processors, touch screens, solar cells and in the production of materials for the manufacture of personal protective equipment, i.e. products and equipment intended to protect the health and life of users. The literature review presented in this paper concerns physical and mechanical properties of composites containing graphene or its structure as well as methods of obtaining polymer, metallic and ceramic composites doped with graphene structures. Data analysis of the potential use of graphene and its composites in personal protective equipment such as monitoring sensors, clothing and security equipment such as ballistic armor, helmets and protective clothing were also reviewed and summarized.

In cases where an explosive atmosphere contains several types of inflammable and/or combustible gases, steams or powders, the protection measures must be appropriate to the highest possible danger. However, the employer must pay special attention to the workplace and to any factor that can influence the working conditions, especially to those related to the workers. Therefore, any device, tool or equipment used by the human operator must possess special properties. In addition to protective clothing, workers who work at heights must receive personal protective equipment against falling that includes multiple linking elements known as carabiners. The carabiners used in this equipment must be made of non-sparking material. The aim of this paper is to propose a spark characteristic improvement of carbon steel used in carabiners manufacturing by deposition of zinc phosphate coating.

ABSTRACTBackgroundMany challenges lie ahead when dealing with COVID-19, not only related to the acceleration of the pandemic, but also to the prediction of personal protective equipment consumption to accommodate the explosive demand. Due to this situation of uncertainty, the hospital administration encourages the excess stock of these materials, over-stocking products in some hospitals, and provoke shortage in others. The number of available personal protective equipment is one of the three main factors that limit the number of patients at a hospital, along with the number of available beds and the number of professionals per shift.ObjectiveIn this scenario, a challenge is to build an easy-to-use expert system to predict the demand for personal protective equipment in hospitals during the COVID-19 pandemic, which can be updated in real-time for short term planning.MethodsWe propose naive statistical modeling, which combines historical data of the consumption of personal protective equipment by hospitals, current protocols for their uses and epidemiological data related to the disease, to build predictive models for the demand for personal protective equipment in Brazilian hospitals during the pandemic. We then embed our modeling in the free Safety-Stock expert system, which can provide the safety stock levels for a particular hospital.ResultsThe Safety-Stock system provides the prediction of consumption/demand for personal protective equipment over time, indicating the moment when the hospital reaches maximum consumption, the estimate of how long it will work in this state, and when it will leave it.ConclusionWith our predictions, a hospital may have its needs related to specific personal protective equipment estimated, taking into account its historical stock levels and possible scheduled purchases. The tool allows for the adoption of strategies to control and keep the stock at safety levels to the demand, mitigating the risk of stock-out. As a direct consequence, it also enables the interchange and cooperation between hospitals, aiming to maximize the availability of equipment during the pandemic situation.
