Working with a chainsaw is a risk for arborists. When handling a chainsaw, serious injuries can occur, particularly to the arms. For this reason, arborists must wear personal protective equipment (PPE) against chainsaws. This protective equipment corresponds to PPE category 3. Current protective gloves have several textile layers as protection. These gloves offer protection up to a chain speed of 24 m/s (class 2). No protective gloves for class 3 are available. A new approach is the solution presented in the paper, in which a smart glove and a modified electrical chainsaw can close this gap. For the development of the glove, the typical work situation, current accident situations, and accident statistics were analyzed. The legal requirements and standards for the European market and the wearing comfort are discussed; based on these data, gloves were designed that included electronics, and a chainsaw was configured accordingly. The glove was then tested under laboratory conditions to see whether the electronic functions in the glove could switch off the saw as soon as the glove came too close to it. The project showed the potential for smart textiles to overcome the limits in the layering of protective textiles.

Background: An edible oil factory is a labor-intensive and technologically complex industry, with workers potentially exposed to a variety of dangers associated with such industries. Personal protective equipment is a universal, legal requirement, and an important strategy for preventing occupational injuries and illnesses caused by workplace hazards. However, such industries receive little attention, especially in Ethiopia.

Background: During the COVID-19 pandemic, severe respiratory failure is a life-threatening condition, and life-saving tracheal intubation is a high-risk aerosol- and droplet-generating procedure. It is crucial to protect healthcare workers without compromising patient safety during intubation. The use of personal protective equipment (PPE) and different types of laryngoscopes are measures to reduce the risk of infectious transmission that might impact the intubation process.

This study focuses on reducing the weight of oxygen respirators in firefighters' personal protective equipment (PPE), which currently accounts for about 56% of the total weight. The heavy PPE, weighing between 20 and 25 kg, restricts movement and can lead to musculoskeletal injuries. To address this, the study investigates using a carbon fiber-reinforced composite for the backrest of the oxygen respirator to reduce weight while maintaining strength.

Biogas contributes to environmental protection by reducing greenhouse gas emissions and promoting the recycling of organic waste. Its utilization plays a crucial role in addressing the challenges of climate change and sustainability. However, the deterioration of process plants involved in biogas production due to corrosion has a critical impact on the safety and durability of their operations.
