“…There are so many impacts resulting from this pandemic, especially on human health and hampering daily activities (Damilos et al, 2022;Zheming & Yuan, 2020). Even so, the world of education is still trying to break the chain of the spread of Covid-19 in Indonesia through the Building Construction course.…”

Building Construction is a compulsory subject in the Building Engineering Education Study Program which is expected in this course to have the ability to design systems and infrastructure in the civil engineering field as needed by considering various constraints such as economic, environmental, health, and security constraints. Covid-19 harms life so the world of education also wants to participate in breaking the spread of the Covid-19 virus. The subsidized houses that have been built have met the existing requirements, although they are not perfect, they can still be said to be livable houses. However, a serious problem is that after being given a lot of people added the initial building but did not meet the requirements. This development research produces project-based teaching materials products. This study uses the development of Borg and Gall with the stages of analyzing potential problems, data collection, product design, design validation, design revision, product testing, revision, and reporting. The teaching materials developed contain the characteristics and designs of disaster response houses adapted to the Building Construction course material and are project in nature. The results of the study obtained that the teaching materials developed were suitable for use as teaching materials in the process of learning activities based on the overall average score of the material expert aspect of 3.6 and the media expert 3.6 very good category.

Airborne pollutants pose a significant threat in the occupational workplace resulting in adverse health effects. Within the Industry 4.0 environment, new systems and technologies have been investigated for risk management and as health and safety smart tools. The use of predictive algorithms via artificial intelligence (AI) and machine learning (ML) tools, real-time data exchange via the Internet of Things (IoT), cloud computing, and digital twin (DT) simulation provide innovative solutions for accident prevention and risk mitigation. Additionally, the use of smart sensors, wearable devices and virtual (VR) and augmented reality (AR) platforms can support the training of employees in safety practices and signal the alarming concentrations of airborne hazards, providing support in designing safety strategies and hazard control options. Current reviews outline the drawbacks and challenges of these technologies, including the elevated stress levels of employees, cyber-security, data handling, and privacy concerns, while highlighting limitations. Future research should focus on the ethics, policies, and regulatory aspects of these technologies. This perspective puts together the advances and challenges of Industry 4.0 innovations in terms of occupational safety and exposure assessment, aiding in understanding the full potential of these technologies and supporting their application in industrial manufacturing environments.

Integrating Exposure Assessment and Process Hazard Analysis: The Nano-Enabled 3D Printing Filament Extrusion Case

et al. 2023

Nanoparticles are being used in novel applications of the thermoplastics industry, including automotive parts, the sports industry and leisure and consumer goods, which can be produced nowadays through additive manufacturing. However, there is limited information on the health and safety aspects during the production of these new materials, mainly from recycled sources. This study covers the exposure assessment to nano- and micro-size particles emitted from the nanocomposites during the production of filaments for 3D printing through a compounding and extrusion pilot line using recycled (post-industrial) thermoplastic polyurethane (TPU) and recycled polyamide 12 (PA12), which have been also upcycled through reinforcement with iron oxide nanoparticles (Fe3O4 NPs), introducing matrix healing properties triggered by induction heating. The assessment protocol included near- and far-field measurements, considering the extruder as the primary emission source, and portable measuring devices for evaluating particulate emissions reaching the inhalable zone of the lab workers. A Failure Modes and Effects Analysis (FMEA) study for the extrusion process line was defined along with a Failure Tree Analysis (FTA) process in which the process deviations, their sources and the relations between them were documented. FTA allowed the identification of events that should take place in parallel (simultaneously) or in series for the failure modes to take place and the respective corrective actions to be proposed (additional to the existing control measures).
