USE OF THE BMP SYSTEM FOR BLOCKING OF DANGEROUS ENERGIES DURING REALIZATION OF WORKS FROM REPAIR AND MAINTENANCE OF TECHNIQUE

Creating healthy and safe working conditions is the main task of the employer when performing high-risk work. Practice shows that the cause of accidents during the repair and maintenance of equipment are uncoordinated and erroneous actions of staff, resulting in incorrect supply of hazardous energy to the installation where people work. In order to prevent injuries at metallurgical enterprises there is a need to revise and modernize the existing approach to control the supply of hazardous energy during repairs, improve the current labeling system of access to repairs of technological equipment based on the experience of advanced world technologies. Audit). The BMP system is used to perform maintenance and repair of equipment, as well as any other cases where personnel need to enter the danger zone, and includes not only the actual process of blocking and marking, but also all other activities: documentation, organization of storage and issuance of BMP devices, training and testing of personnel knowledge According to the analysis, the current tag system at the metallurgical enterprises of Ukraine is inferior in efficiency to the BMP system, which allows you to almost completely eliminate the risks associated with the human factor in the repair and maintenance of equipment. The foreign experience of using hazardous energy blocking and labeling systems and the existing legal framework on this issue in Ukraine are analyzed. According to the results of research, the basic principles of using the BMP system at the enterprises of the metallurgical industry are established. The sequence of BMP procedure implementation is offered. The information on the basis of which the BMP map is formed is considered in detail. An important stage in the formation of this map is the assessment of industrial risks of exposure to hazardous energies in the process of repair and maintenance of equipment. The direction of further research on the implementation of the BMP system and the legalization of the BMP standard at the state level is substantiated.

Anti ice build-up method on small railway culverts

One of the most important problems with the small railway culverts operation is the ice build-up on the inlets of these structures. This problem is universal in occurrence, but the northern regions are the main danger zone. The objective of this paper is to determine the phenomenon causes and factors that directly affect it, as well as to find a way to solve the problem. A small culvert is considered as a subsystem of the «Road/Railroad» system, which allows us to execute complete analysis and description of the technical and special production processes accounting related to design, construction, maintenance, scheduled, overhaul, as well as reconstruction, and solution of some problems, during the culverts operation. Consistently considered reliability issues during structural engineering: functional, structural, and informational. described Regulations that allow determining the nature of the ice build-up problem on pipes. In the analysis process of the existing methods for solving the problem, it was found that each method has its particularities, but in the end, is ineffective. According to the methodology presented by the authors, under Professor’s Yu.L. Scheviev supervision, has been developed a completely new approach, that provides effective financial resources use, in relation to the work result during the entire object’s life cycle, in form of a long structure operation period with the elimination of the ice build-up problem possibility. Technique application leads to a sharp decrease in the technical work frequency at small culverts. The paper analyzes a detailed algorithm for using the technique based on the calculation of a small culvert with a circular cross-section.

Enhanced IoT Based Child Missing Alert System Using RSSI

Our proposed system discusses the concept of a smart wearable device connected to their parent’s mobile phone for children and their parents respectively. In this project we propose that to let the system be divided into three parts, namely the safe, intermediate and danger zones. If the child is within the safe zone, then no buzzer is sounded whereas if the child is in the intermediate range a buzzer alert will be sounded. If the child crosses the ‘danger’ zone, the buzzer is sounded with an immediate notification sent to the parent. In case the child goes out of danger zone, a GPS module is attached that would help parent know the exact location of the child once he/she is outside the 100meters of radius from the parent. This project also has features to sense the child’s temperature and heartbeat along with notifying the child’s parent in case the child has an accident using the temperature, heartbeat and pressure sensors respectively. The RSSI is used for distance sensing whereas GSM is used for notification sending to the parent’s mobile phone.

Multipurposed Intelligent ID Card for Social Distancing & Safety Emergency alert systems

This proposed invention is related with multipurpose device which is intelligent id card provided to the employee will help track and trace by connecting to the respective corporate server network. This server acts as a central intelligence and provides a dashboard that will help set up and get data and insights. These constantly monitor the smart cards and transmit their position to the central system. Many important multi-tasking tasks can be performed using this smart ID card which has the ability to provide real-time location information and also automatically identify if the person is where they should be. Accidents, such as a person walking into a danger zone, can be easily reported. In the event of a fire, you can quickly find the total people count along with the latest positions. The crowding of places such as offices, shops, workplaces, bathrooms, canteens, etc. it can be reported in real-time in order to avoid any infections. The temperature measurement alone is useless if the readings are not associated with the employee and are recorded to analyses trends. The proposed ID card will keep track of the number of times the employee has washed their hands. If not, a social notification will be raised. With real-time monitoring, you can easily provide daily attendance data to HR for payroll calculation and contract work invoice review. The employee's Bluetooth tag will help track time spent within the authorized area and will sound an alarm if the person enters a danger zone, all in real-time. The employee tag will allow the employee to send an SOS signal in case of any danger or panic situation. It will not be necessary to keep an attendance register. The tag will automatically record the time of entry and exit. A body sensor attached to the ID card will detect if the card is moved away from the body and kept aside. Hence, there is no possibility of cheating. The battery inside the card would last 5 to 10 years. IP 65, therefore resistant to water and rain. No maintenance is required.

Location-dependent threat and associated neural abnormalities in clinical anxiety

Anxiety disorders are characterized by maladaptive defensive responses to distal or uncertain threats. Elucidating neural mechanisms of anxiety is essential to understand the development and maintenance of anxiety disorders. In fMRI, patients with pathological anxiety (ANX, n = 23) and healthy controls (HC, n = 28) completed a contextual threat learning paradigm in which they picked flowers in a virtual environment comprising a danger zone in which flowers were paired with shock and a safe zone (no shock). ANX compared with HC showed 1) decreased ventromedial prefrontal cortex and anterior hippocampus activation during the task, particularly in the safe zone, 2) increased insula and dorsomedial prefrontal cortex activation during the task, particularly in the danger zone, and 3) increased amygdala and midbrain/periaqueductal gray activation in the danger zone prior to potential shock delivery. Findings suggest that ANX engage brain areas differently to modulate context-appropriate emotional responses when learning to discriminate cues within an environment.

Sensor Modules for Enhancement of Safety Performance in Construction Safety Management

Safety management is very important for construction sector as it is the most hazardous working environments when it comes to occupational fatalities. The high cases such as injuries at the workplace, illnesses, and fatalities often caused harm to the workers and create the delay on the work progress. Therefore, this paper reviewed the whole operation process of the sensor modules that enhanced safety performance to prevent accidents occurred on construction site. By providing lab scale location-based safety management services to the workers, this technology able to allow a speedy response in the event of accident. From the benchmark conducted, there are three study that had been conducted previously using vibrational alert signal which identified as an accurate transmitted especially inside a danger zone, as the vibrational function of the sensor module able to function within the designated range. The second benchmark shows that previous study able to identify errors in the location information of the workers arising from obstacles, even though so the technology able to conveyed within the designated range as well. Thirdly, the previous study able to shows the information of a fall was conveyed quickly upon occurrence, and the previous study showed that fall able to identified using the context-aware information from the sensor module. The findings showed that the real-time location and context-aware information collected from the sensor module can be used to prevent accidents and respond quickly in the event of a fall. However, the vibration signal which generated by sensor module was insufficient to alert the workers when approaching the danger zone at construction site. Therefore to improve the whole development of prototype sensor module a further study is needed to incorporate the vibrational and alarm signal for recognising accidents upon occurred for enhancement safety management at construction sites.
