Harmful gas contamination causes threat to human life. In India, the manholes are still cleaned by unskilled workers. While cleaning the drainage the toxic gases like carbon monoxide, methane are emitted. These harmful gases can endanger the life of sanitation workers.To solve this problem we have made a tool kit which detects the presence of harmful gases, calculate the concentration level and identify safety limit, thereby protecting life of workers. The harmful gases can be detected by using different gas sensors. The sensors can detect the harmful gas along with their concentration in ppm. The sensed value is given to Arduino, if the value exceeds the threshold value then an alert message is send to the base station so, that the worker can immediately evacuate the area, thereby protecting from danger. The alert message is generated using GSM technology. So, using this tool kit sanitation workers can be protected from hazardous
