Abstract

In this paper, we intend to produce a safety system for manual scavengers. Unminding “Prohibition of manual scavengers and their rehabilitation act”,2013,there are still many private organizations across the Indian states, hire labourers for very low cost of around 1.5k whereas cleaning process abiding law and using equipments like suction tanks, cleaning robots, sewer lorries would cost around 5k for the same task. The ultimate reason for such violation of act is the monetary factor on both sides. When such manual scavengers are exposed to gases like methane, ammonia, hydrogen disulphide etc., which are present inside the manhole, drainage or sewage system, they encounter many health troubles. Few of them include breathlessness, fatigue, bacterial and viral invasion, infections, loss of consciousness and ultimately death in worst case. During such times, the labourers will not be in line of sight and as all happens in sudden, the victim cannot intimate the supervisors above and as a result, they go unconscious. If not rescued within time, the victim dies. In order to prevent this from happening, we propose a safety system that continuously monitors the toxic gas levels, heart rate of the subject and the respiratory rate. If anything abnormal detected, the system immediately triggers buzzer, an alert message that can be seen by the supervisor above using IoT. This in turn helps rescue faster, so that the victim can be hospitalized before the vitals goes extremely down. The application of the system is flexible so that it can be used in detection of other gases by modulating the program accordingly and setting the required threshold.
