Condition/ Challenges Hazards/Risks involved How does we mitigate the risk/Control measures to be taken Live Railway lines Slips, Trips, and Falls Noise Hazards Railway tracks and surrounding areas can be uneven, with gravel, loose debris, or wet conditions, increasing the risk of slips, trips, and falls. The noise generated by passing trains, heavy machinery, and construction work can lead to hearing loss or difficulty in communication. Keep the work area clean and free of obstructions such as loose cables, tools, or debris. Use warning signs to highlight trip hazards or changes in elevation. Provide workers with hearing protection such as earplugs or earmuffs. Implement proper communication methods (e.g., hand signals, flags, walkie talkie) to maintain clear communication in high-noise environments. Risk Assessment and Planning: Conduct a comprehensive risk assessment before any work begins, in collaboration with railway authorities. Develop and train workers on a detailed emergency response plan Risk Assessment

High Equipment, vehicles, or materials may accidentally encounter overhead power lines during transport or construction, causing electrocution, arc flash or equipment damage Conduct a thorough risk assessment before starting work, identifying the location of all power lines Follow and implement shutdown procedure with LOTO implementation. Have fire extinguishers rated for electrical fires readily available. Ensure proper height clearance/ goal post arrangement for cranes, trucks, and other equipment near overhead lines. Use spotters and flaggers to guide equipment safely around power lines. Post warning signs and use physical barriers to restrict access to live power lines. Use non-conductive tools and insulated equipment when working near power lines. Risk Assessment

11. Condition/ Challenges Hazards/Risks involved How does we mitigate the risk/Control measures to be taken Forest Areas, Elephant corridor, Wildlife, snake prone and mosquito prone areas Encounters with Large Wildlife Injury from Smaller Wildlife (Monkeys, Wild Boars, etc.), Can lead to injury or death due to trampling or aggressive behavior, especially in areas known as elephant corridors where animals regularly move. Smaller animals, such as monkeys, wild boars, or deer, can cause injuries either by aggression or by accidentally running into the worksite. Identify and mark wildlife corridors to avoid disturbing the natural movement of animals. Maintain safe distance. Implement work scheduling to avoid peak wildlife activity times, such as dawn, dusk, or nighttime. Use warning systems or animal deterrents, such as lights, fences, or sound devices, to alert workers of approaching animals or discourage their entry into work zones. Train workers on wildlife behavior and escape routes, including what to do during an animal encounter (e.g., keeping a safe distance, not provoking the animal). Avoid leaving food or waste in open areas, as it can attract animals like monkeys or wild boars. Risk Assessment

12. Condition/ Challenges Hazards/Risks involved How does we mitigate the risk/Control measures to be taken Forest areas, Elephant corridor, Wildlife, snake prone and mosquito prone areas Snake Bite Mosquito-Borne Diseases (Malaria, Dengue, etc.) Areas with stagnant water or heavy vegetation, mosquitoes can spread diseases such as malaria, dengue fever, and chikungunya, leading to significant health risks for workers. Clear vegetation & Provide workers with snake gaiters that covers the legs. Educate workers on snake behavior and how to identify dangerous species common to the area Keep first-aid kits with snakebite treatment & antivenom on site. Ensure workers know the location of nearby medical facilities and have a plan for immediate evacuation in case of a snake bite. Implement mosquito control measures, such as draining stagnant water, spraying insecticides, and eliminating breeding grounds. Ensure workers wear long-sleeved clothing and trousers to minimize exposed skin Risk Assessment

13. Condition/ Challenges Hazards/Risks involved How does we mitigate the risk/Control measures to be taken Public Domain area (village residential, markets, Schools, roads & pathways etc ) Pedestrian and Public Safety Vehicle Traffic Narrow Pathways and Congested Areas Unstable Ground or Excavations Risk of injury to pedestrians, including children, elderly, and residents, as they move through or near the work area Interaction between work activities and local vehicle traffic, which could lead to accidents or collisions. Narrow village pathways and congested market areas make it difficult to manage equipment, vehicles, and materials, leading to potential accidents or property damage Erect barricades, safety signage in local language, road marshals and warning tapes to restrict access. Provide clear communication with administration and local residents to inform them of restricted access. Install temporary fencing or hard barricades around excavations to prevent unauthorized access. Designate certain workers to act as public safety monitors to watch for unauthorized access, especially from children. Work with local authorities or residents to protect nearby structures by using protective barriers or avoiding heavy machinery near sensitive areas. Risk Assessment
