Smart Safety Helmet for Safe Coal Mining

In any production and service industry, the safety of their workers/labors is very critical. The workers directly related with production are generally more prone to the threats because of their exposure to electro-mechanical, chemical, thermal, environmental, civil and other hazards. The coal mining industry in one of the most risky industries in terms of workers’ lives hazards. In the under-developed countries, any potential disaster in the underground mining turns into huge catastrophic losses of both the human lives and equipment. This paper presents some statistical data of mining disasters worldwide and propose an architecture for a smart helmet to be used by miners for their safe working inside the coalmines.

SMART SAFETY SHOES: INTERNET OF THINGS BASED ANTI FATIGUE SENSORS TO PREVENT MUSCULOSKELETAL DISORDERS

Background: Occupational injuries in Indonesia increase every year where one of the causes is fatigue. Musculoskeletal disorders (MSDs) is the most common occupational injuries that happen. This problem can be caused by ergonomic factors such as standing position for long periods of time. Purpose: Safety shoes can be personal protective equipment to prevent MSDs complaints on the feet. Method: Additional designs and features are needed to increase the effectiveness of safety shoes. Smart Safety Shoes are shoes equipped with anti-fatigue sensors where there is a pulse detector and a heating sensor and apply Internet of Things technology by focusing attention to ergonomic concepts. The sensor system in the shoes is connected to the android application via wifi network. The application displays pulse rate, temperature, oxygen saturation, warning and recommendation information, as well as heating sensor control. Result: From the results of trials using a random sample, the levels of comfort and safety of these shoes are 83,3% and 83,3%, so they are quite effective to use. Conclusion: Foot fatigue can be relieved by turning on the heating sensor for about 5-10 minutes for maximum comfort so that MSDs can be prevented as early as possible.

COFLEX: FLEXIBLE BRACELET ANTI COVID-19 TO PROTECT CONSTRUCTION WORKERS

To implement the protocol contrasting the diffusion of Covid-19, the employer is required, to ensure the safety and health of the worker at work, to adopt measures related to the control of body temperature (with respect for privacy), the minimum distance during work and all other activities such as breaks, canteen breaks, access to toilets, in addition to the adoption of specifically developed safety procedures, such as e.g. the use of man-down detection devices. In this context, the project aims to illustrate a system able of providing support in the safeguarding of workers' health on construction sites. This system, based on information received from sensors capable of identifying workers' positions (e.g., if less than 1m away) and their vital parameters (e.g., body temperature, gasped breathing), as well as moving objects inside the construction site area (e.g., to check if a worker is passing under a moving crane), will raise early alerts directly to the workers and/or to the central software, with respect for privacy, to immediately activate all the necessary measures to mitigate the risk. The system, based on the data communicated by the various sensors, will store and process them for the purpose of extracting useful information for risk management. The proposed system configured itself as a new product taking advantage from a high Technology Readiness Level maturated from the Smart Safety Belt already developed by some of the authors.
