Positive pressure ventilators used by 97.7% of officers of the National Fire Service in Poland, are characterized by work that is not in line with the expectations of the firefighters. In order to improve the technical and operational features of these devices, a survey was conducted among 25,000 eligible firefighters, identifying the application of these devices, problems in use and expected development directions. A total of 682 officers voluntarily completed the survey. Based on their findings, it was determined that ventilators are most often used to smoke out buildings after or during a fire. Mentioned problems when using these devices were mainly noise (78.2%), exhaust emissions (68.5%), and impediments to mobility through the device’s relatively heavy weight (40.2%). Other inconveniences were mentioned by less than 20% of firefighters. Polish firefighters expect the development of these devices mainly in terms of the above-mentioned features (noise reduction (81.7%) and reduction of the weight and size of the ventilators (about 50%)). Other expectations relate to the improvement of smoke removal in buildings: increasing the efficiency of smoke removal (46.4%) and efficiency regarding the rate of smoke removal in a building by increasing the size of the incoming airflow from the building’s surroundings (33.2%). About 15% of firefighters expect changes in the operation of the ventilator itself, that is, an increase in the effective operating time (electric ventilators) and an increase in the device’s uptime. The article also presents suggestions for device development based on the available state of the art.

Smart personal protective equipment (PPE) is the future of improved occupational health and safety, and nanotechnology facilitates the development of critical smart PPE components such as smart textiles, wearable/flexible electronics, and augmented reality among others. Smart PPE utilizes sensing and communication technology in a way that is non-intrusive to either improve workplace safety or enhance occupational capabilities. The development of such smart PPE requires a multidisciplinary approach. This paper investigates the current state of PPE technologies for firefighters, healthcare workers, police/military, and construction workers. The modern PPE needs are identified from both end user surveys as well as expert third-party studies. There are already some smart PPE solutions for the challenges identified. Recent advances in stretchable and textile-based electronics, enabled by nanotechnology, demonstrate almost all imaginable solutions to the unmet needs that PPE users and expert advisor groups have identified. However, integration into smart PPE requires attention to the unique harsh conditions of hazardous workplaces. This review aims to inspire researchers in the field of flexible and printed electronics to develop and improve future smart PPE.

PurposeThe purpose of this paper is to develop a theory and provide empirical support for the re-conceptualization of usefulness as a multidimensional construct based on the technological roles of automation and computerization.Design/methodology/approachA non-experimental transverse design is followed. Data were gathered using a questionnaire. The participants were users of enterprise resource planning systems. The analysis technique used was the structural equation model.FindingsResults show that the proposed conceptualization has empirical grounding as well as sufficient predictive validity.Research limitations/implicationsThe empirical evaluation was developed using only one type of information system (IS).Originality/valueThis study expands on the existing literature by proposing and empirically evaluating a multidimensional conceptualization of usefulness to try to clarify how a system is useful and, once a greater granularity of usefulness is established, helping to improve the design and construction of information systems.
