Bengaluru is one of the fastest growing cities in India known as the 'Silicon Valley of India'. The Bruhat Bengaluru Mahanagara Palike (BBMP) is responsible for civic infrastructure in Bengaluru. There are many hazards for workers maintaining sewers and manholes, including toxic gases like hydrogen sulfide, ammonia, and methane which can cause death. Proper safety procedures and training must be followed to protect workers, such as using protective equipment, detecting gases, and supervising work. Recent incidents show the need to enforce safety compliance by contractors to prevent loss of lives in hazardous working conditions.

- 15. Sewage and Gray Water. Sewage or black water includes any wastes contaminated by human excrement and other effluent (liquid waste), such as from urinals and toilets. Gray water includes wastewaters uncontaminated by human excrement such as liquids from drains, sinks, sculleries, drinking fountains, showers, washing water, food wastes, laundry waste, etc.
- 16. Why it is harmful? The major harm what results in Death is Toxic gases Sewer gas is a complex mixture of toxic and nontoxic gases produced and collected in sewage systems by the decomposition of organic household or industrial wastes, typical components of sewage. Sewer gases may include Hydrogen sulfide, Ammonia, Methane, Carbon monoxide, Sulfur dioxide and nitrogen oxides.
- 17. Common Hazards in Tanks and Sewer lines: 1. Atmospheric hazards 2. Biological hazards 3. Physical hazards 4. Mechanical hazards Note: Other hazards may include inadequate ventilation, poor visibility, and heat stress.
- 18. 1. Atmospheric Hazards Atmospheric hazards include oxygen-deficiency and flammable or toxic gases such as methane and hydrogen sulfide. Methane gas is colorless, odorless and tasteless, but is highly flammable and is considered an asphyxiant. Hydrogen sulfide (H2S) is also colorless and flammable, but it is highly odorous and extremely toxic to humans. At approximately 100150 ppm of H2S, the olfactory nerve is paralyzed after a few breaths. Within a very short time, the sense of smell disappears, giving a false sense that the harmful gas has gone away. These gases are detectable only by properly calibrated instruments
- 19. Effects of the Toxic gases on Humans
- 20. Hydrogen sulfide: Symptoms of acute exposure include nausea, headaches, delirium, disturbed equilibrium, tremors, convulsions, and skin and eye irritation. Inhalation of high concentrations of hydrogen sulfide can produce extremely rapid unconsciousness and death. Hydrogen sulfide (H2S) is also colorless and flammable, but it is highly odorous and extremely toxic to humans.
- 21. Ammonia Exposure to high concentrations of ammonia in air causes immediate burning of the nose, throat and respiratory tract. This can cause bronchiolar and alveolar edema, and airway destruction resulting in respiratory distress or failure. Inhalation of lower concentrations can cause coughing, and nose and throat irritation
- 22. Methane ( The most common reason for Man-hole accident ) Methane in its gas form is an asphyxiant, which in high concentrations may displace the oxygen supply you need for breathing, especially in confined spaces. Decreased oxygen can cause suffocation and loss of consciousness. It can also cause headache, dizziness, weakness, nausea, vomiting, and loss of coordination.
- 23. How to detect?
- 24. Biological hazards Include pathogens (e.g., bacteria, viruses, protozoa, parasitic worms, fungi) and other infectious microorganisms that can cause illnesses such as hepatitis, typhoid fever, dysentery and cholera. Inhaling or ingesting contaminated mists may result in serious illnesses. May not be immediate but leads to severe illness
- 25. Physical hazards: Include slips, trips, and falls due to slippery and sloping surfaces; limited access and egress; corroded ladder rungs; and obstructions by piping and other structures. There is also the risk of receiving punctures and cuts from sharp edges
- 26. Mechanical hazards Include energized equipment; rotating machinery; and waste stream leaks. Before any servicing is performed where the energization or startup, or the release of hazardous energy may occur, all energy sources must be identified and isolated, and the machinery, equipment, or system rendered inoperative. Mechanical hazard is comparatively minimum than the Other hazards.
- 27. Safe working procedure: Select the working site. Clear the area from Pedestrians and vehicles ( using barricade ). Analyze for the Toxic gases and other notable hazards. Prepare a Work permit. Arrange and follow the process according to work permit. Supervise the work.
- 28. How to protect..? Although Level A or B protective gear is not required, to avoid liquid contact with exposed skin, it is recommended that full-body, impervious suits are worn in addition to using rubber boots, gloves, hard hats and eye protection Have extra flashlights and two-way radios readied for communication. Have a first-aid kit, an eyewash and flushing station, neutralizing solutions, cleaning equipment, and emergency medical services readily available
- 29. Training Workers must be trained to recognize potential hazards, use proper work practices and procedures, recognize adverse health effects, understand the physical signs and reactions related to exposures, and are familiar with appropriate emergency evacuation procedures. They must also be trained to select and use the appropriate Personal Protective Equipment.
- 30. The Complete news..!

- 76. The detergent industry is hastening the death of the city's water bodies. Toxic foam in Bellandur lake in Bengaluru - Deccan chronicle
- 77. Impacts on people.. 1) The foam is toxic and reports say it is carcinogenic. It causes breathing difficulties, irritation on the skin, besides spreading an unbearable stench. Whenever it rains, the lake overflows, spilling the froth onto roads, blocking traffic. 2) In 2015, foam from the lake spilled over on to roads and other spaces surrounding the lake. At the time, authorities insisted that the foam was from the detergents households discharged into the river. Last year in April, the froth on the lake had caused a traffic jam. More recently, on May 7, the citys Bellandur lake caught fire.The resulting thick smog surrounded the heavily- polluted lake, making it difficult for the passers-by to breathe.
- 78. Reasons for the froth.. The indiscriminate discharge of household waste and industrial effluents into lakes is what causes the toxicity, leading to the water body foaming. A study at the Indian Institute of Science in Bengaluru, found that around 90% of the lakes in Bengaluru were affected because of the sustained inflow of untreated sewage and industrial effluents. Another thing to blame is detergent: Experts say the ubiquity of washing machines in urban India and indiscriminate use of detergent by households have come together to turn Bellandur Lake into a foamy disaster.
- 79. Prevention.. Regulate the effluent release into water bodies Advice the apartment residents about the necessary actions about using detergents.
