The exposure to extreme temperatures in workplaces involves physical hazards for workers. A poorly acclimated worker may have lower performance and vigilance and may therefore be more exposed to accidents and injuries. Due to the incompatibility of the existing standards implemented in some workplaces and the lack of thermoregulation in many protective equipment, thermal stress remains one of the most frequent physical hazards in many work sectors. However, many of these problems can be overcome with the use of smart textile technologies that enable intelligent thermoregulation in personal protective equipment. Smart textiles can detect, react and adapt to many external stimuli. Interconnected sensors and actuators that interact and react to existing risks can provide the wearer with increased safety, protection and comfort. Thus, the skills of smart protective equipment can contribute to the reduction of errors and the number and severity of accidents in the workplace, and thus promote improved performance, efficiency and productivity.This review provides an overview and opinions of authors on the current state of knowledge on these types of technologies by reviewing and discussing the state of the art of commercially available systems and the advances made in previous research works.

The exposure to extreme temperatures in workplaces involves physical hazards for workers. A poorly acclimated worker may have lower performance and vigilance and therefore may be more exposed to accidents and injuries. Due to the incompatibility of the existing standards implemented in some workplaces and the lack of thermoregulation in many types of protective equipment that are commonly fabricated using various types of polymeric materials, thermal stress remains one of the most frequent physical hazards in many work sectors. However, many of these problems can be overcome with the use of smart textile technologies that enable intelligent thermoregulation in personal protective equipment. Being based on conductive and functional polymeric materials, smart textiles can detect many external stimuli and react to them. Interconnected sensors and actuators that interact and react to existing risks can provide the wearer with increased safety, protection, and comfort. Thus, the skills of smart protective equipment can contribute to the reduction of errors and the number and severity of accidents in the workplace and thus promote improved performance, efficiency, and productivity.

The COVID-19 pandemic has affected citizens and healthcare workers worldwide due to a number of important factors. The transmission of the SARS CoV-2 microorganism, the pathogen that causes COVID-19 infection, occurs through droplet and aerosol spread due to coughs and sneezes from infected patients. A panicked public began hoarding medical supplies and personal protective equipment (PPE), leaving healthcare workers to care for patients without adequate protection. A literature review was conducted to better understand the options available to hospital and healthcare system administrators as they develop necessary protocols for the conservation and possible reuse of PPE. This review is based upon the peer-reviewed studies of various scientific investigators, biotechnology researchers, governmental agency health officials, including meta-analyses, preliminary/pilot studies, and policy statements. Current findings indicate that extended usage of N95 respirators is practical since there are methods available for the decontamination/repeated use of N95 respirators. In evaluating the efficacy of such methods, the safety of healthcare workers is important in deciding which method to recommend. Available evidence supports the use of the Bioquell Hydrogen Peroxide Vapor (HPV) system for decontaminating N95 respirators. Information on other PPE will also be discussed about more specific items. Informed decisions regarding the policies of hospitals and healthcare systems must be considered, and with the safety of healthcare workers in mind, both factors influenced the recommendations made in this comprehensive review.

Abstract Natural biological systems are constantly developing efficient mechanisms to counter adverse effects of increasing human population and depleting energy resources. Their intelligent mechanisms are characterized by the ability to detect changes in the environment, store and evaluate information, and respond to external stimuli. Bio-inspired replication into man-made functional materials guarantees enhancement of characteristics and performance. Specifically, butterfly architectures have inspired the fabrication of sensor and energy materials by replicating their unique micro/nanostructures, light-trapping mechanisms and selective responses to external stimuli. These bio-inspired sensor and energy materials have shown improved performance in harnessing renewable energy, environmental remediation and health monitoring. Therefore, this review highlights recent progress reported on the classification of butterfly wing scale architectures and explores several bio-inspired sensor and energy applications.

Recent Trends

The coronavirus SARS-CoV-2 pandemic has affected over one hundred million people worldwide and has resulted in over two million deaths. In addition to the toll that coronavirus takes on the health of humans infected with the virus and the potential long term effects of infection, the repercussions of the pandemic on the economy as well as on the healthcare system have been enormous. The global supply of equipment necessary for dealing with the pandemic experienced extreme stress as healthcare systems around the world attempted to acquire personal protective equipment for their workers and medical devices for treating COVID-19. This review describes how 3D printing is currently being used in life saving surgeries such as heart and lung surgery and how 3D printing can address some of the worldwide shortage of personal protective equipment, by examining recent trends of the use of 3D printing and how these technologies can be applied during and after the pandemic. We review the use of 3D printed models for treating the long term effects of COVID-19. We then focus on methods for generating face shields and different types of respirators. We conclude with areas for future investigation and application of 3D printing technology.

The article is devoted to the investigation of the current state of legal regulation of provision of agricultural workers with personal protective equipment, analysis of legislative novelties and highlighting the main disadvantages in this area with the formulation of proposals for their elimination. It is defined that the legal framework for provision of workers of agricultural enterprises with personal protective equipment (hereinafter - PPE) is currently being updated, primarily due to Ukraine’s international and European integration obligations to adapt domestic legislation in this area to international requirements. It is proved that the main positive innovations are: the introduction of a combination of the mandatory minimum provision of workers by PPE with the possibility for the employer to decide on the provision of workers by PPE overtime; giving priority to means of collective protection over PPE; specification of the rights of workers to participate in resolving issues related to the their provision of PPE; regulation of the procedure for selecting PPE by the worker in excess of the established minimum norms. A number of measures are proposed to promote the practical implementation of the provisions of the Minimum Safety and Health Requirements for the use of personal protective equipment in the workplace: development of recommendations for employers to assess occupational risks in the workplace; provision of advisory services in the field of risk assessment at workplaces and on the selection of PPE above the established norms (such services may be provided by the State Labor Service of Ukraine); provision of workplace risk assessment services by the State Labor Service or other entities (this is especially relevant for small agricultural enterprises). A proposal was made to introduce incentives for employers to provide employees (including agricultural enterprises) with PPE by establishing the dependence of the amount of contributions for compulsory state insurance against accidents at work and occupational diseases on the level of occupational injuries / diseases at the enterprise.
