Purpose The Purpose of this research is to initiate the “Fourth Industrial Revolution” by using the Internet of things (IoT), which can be applied to flammable gas condition monitoring and detection of gas leakage and activate fire extinguisher in case of fire accidents. Liquefied petroleum gas (LPG) leakage and explosions cause many injuries and death each year. By developing an automated and remote LPG ppm condition monitoring and fire extinguisher activation system with the help of a cyber-physical system, the rate of accidents and injuries can be reduced to a significant amount. Design/methodology/approach The IoT enabled the sensors to transmit LPG concentration value reading to a mobile app or cloud server and control actuators by connecting all in the same network. In case of a fire accident, the solenoid valve automatically or can be activated by an android application manually, which will be pre-installed in mobile phones. Another advantage of this system is that the gas cylinder or flammable particle source can be closed by closing the solenoid valves attached to their outlets. The first challenge of Industry 4.0 is to develop a cyber-physical system where all physical entities can be monitored and controlled over the internet or another way remotely or from a single point. Findings This fire extinguisher system can be used everywhere and in all types of firefighting because all types of fire extinguishers are commercially available in cylinders where solenoid valves can be used instead of conventional valves. This system will reduce human effort in the fire safety system and reduce the number of losses owing to fire accidents by taking all actions automatically and from a safe distance. The reliability analysis of this system indicated that the working condition for the best outcome is 20–35°C and the baud rate of the controller should be 11.5 kHz. Originality/value The study of pieces of the literature summarizes that this work is unique in terms of the application of Industry 4.0 in the fire safety system and reliability analysis of this system helped to determine the operating condition for the best performance of this system. Some LPG condition monitoring system was developed using IoT before but had many limitations such as working capability during load shading or emergency cases.

The key work of this research is to implement the ‘Fourth Industrial Revolution’ by using the internet of things (IoT) which can be applied to flammable gas condition monitoring and detection of gas leakage and activate fire extinguisher in case of fire accidents. Internet of things enabled the sensors to transmit LPG concentration value reading to the mobile app or cloud server and control actuators by connecting all in the same network. In case of a fire accident, the solenoid valve will be opened automatically or can be opened by an android application manually which will be pre-installed in mobile phones. Another advantage of this system is, the gas cylinder or flammable particle source can be closed by closing the solenoid valves attached to their outlets. The first challenge of industry 4.0 is to develop a cyber-physical system where all physical entities can be monitored and controlled over the internet or another way remotely or from a single point. This fire extinguisher system can be used everywhere and in all types of fire-fighting because all types of fire extinguishers are commercially available in cylinders where solenoid valves can be used instead of conventional valves. Use of robust automatic control system will eliminate the effort of human for continuous monitoring of LPG condition, leakage and in the activation of fire extinguishers by cyber-physical system.

PurposeThe purpose of this paper is to report a study on analysis of barriers for cyber-physical system (CPS) adoption in small and medium enterprises (SMEs).Design/methodology/approachIn Industry 4.0 scenario, Indian SMEs are struggling to bring their manufacturing processes in line with large manufacturing sector. CPS is considered as the backbone of Industry 4.0, and its implementation in SMEs will make significant changes pertaining to manufacturing automation. However, due to the lack of a proper CPS implementation strategy, SMEs face many challenges in its adoption. Hence, this study identified 18 possible barriers and seven performance measures pertaining to CPS adoption in Indian SMEs. Interpretive ranking process (IRP) is used to develop the contextual relationships among CPS barriers. IRP process include structured step-by-step matrix-based approach in which dominance among various alternatives is determined using performance measures developing a structured ranking model.FindingsThe developed IRP model revealed that CPS barriers “Lack of skilled manpower (CPSB2)” and “Lack of robustness with respect to environmental conditions in automotive environments (CPSB7)” are the most significant barriers (top two) hindering CPS adoption in SMEs.Research limitations/implicationsIn the present study, barriers for CPS adoption has been analyzed. In future, barriers for adopting other Industry 4.0 technologies could be analyzed.Practical implicationsThe present research work is one of the few studies which analyzed CPS barriers in SMEs and provided improvement suggestions to the most significant barriers for its smooth adoption. The managerial and practical implications have been derived.Originality/valueThe analysis of barriers for CPS adoption in SMEs is the original contribution of the authors.

PurposeThe occurrence of fire accidents in hospital buildings has become a serious challenge and more serious in developing nations. The purpose of this paper intends to assess fire safety measures in Nigerian hospital facilities. The significance of this study is to ensure that the design and construction of hospital facilities enhance the safety of users and properties.Design/methodology/approachThe data were collected via a case study and questionnaire survey and administered to the facility users. The study survey is to assess the respondents' perception of fire safety measures in hospital facilities and suggest possible policy measures that will be employed to enhance safety.FindingsThis paper found that 91% of the respondents have awareness of fire safety measures in hospital facilities. Electrical faults and combustible materials were identified as the frequent causes of fire occurrences in hospital facilities. This can be averted where flammable materials and electrical appliances are correctly installed, and safety rules enforced. Findings show that safety rules are lax in public than standard private hospitals.Research limitations/implicationsThis paper is limited to fire safety measures in Nigerian healthcare facilities. Future research is needed to evaluate the level of compliance from design, construction and post-construction of precautionary fire safety measures in hospital facilities in Nigeria.Practical implicationsThis paper recommended that designers and hospital administrators should improve on fire safety measures via the development of fire safety management plan and education. Thus, enforcement of fire safety measures in hospital facilities as specified in building codes should be implemented and monitored during and after the design of the hospital buildings. Findings provide valuable lessons on how to improve the fire safety measures in healthcare facilities across the states and other developing countries with similar healthcare situations.Originality/valueThis paper demonstrates that the stakeholders, especially government agencies concern with approval and enforcement of fire safety measures in healthcare facilities need to reawaken to her responsibility because of the lax implementation across the states.
