  1. 1. Industrial hazards…? BY Muhammad Fahad Ansari 12IEEM14“An accident often causing serious injury thatis job related in that it usually happened on awork site such as a factory floor orconstruction sites.”
  2. 2. an industry SO2 waste VOCs CO2 odourHg Raw water materials noise energy BOD
  3. 3.  Main Compounds  Carbon monoxide: CO  Carbon dioxide: CO2  Nitrogen oxides: NOx/NO2  Sulphur oxides: SOx/SO2  Particulate Matter: PM10 Trace compounds  Heavy metals such as Hg, Cd.  Dioxins
  4. 4.  More than 3,000 people die every day because of the work they do for a living  2 million global work related fatalities every year (estimated for year 2000)*  250 million accidents per year worldwide  160 million diseases are caused by people’s jobs  World economic losses are equal to 4% of world wideR.Sangwan

  7. 7. Risk at Fertiliser Units… Chemicals Involved Ammonia Urea – Strong oxidizer, promotes explosive reaction with organic materials. Ammonium Nitrate – Strong oxidant that reacts with combustible and reducing7 material.
  8. 8. Risk at Fertiliser Units Criticalities Ammonia - Methamphetamines (Illegal Drug) Urea – As explosive Ammonium Nitrate – A typical Explosive Ammonia alone is used in about 1/3rd of all Risk Management Program8 chemical Process
  9. 9. Risk in Fertilizer Units Chemicals Handled in Ammonia-Urea Plants  Natural Gas  Naphtha  Ammonia  Other highly flammable gases viz. Carbon mono- oxide, Methane and Hydrogen9
  10. 10. Fundamentals of Electrical Hazards Have You Ever Been Shocked? THE BASICSBasic Electrical Safety
  11. 11. Fundamentals of Electrical Hazards √ More than 3 ma painful shock √ More than 10 ma muscle contraction “no-let-go” danger √ More than 30 ma lung paralysis- usually temporary √ More than 50 ma possible ventricular fib. (heart dysfunction, usually fatal) √ 100 ma to 4 amps certain ventricular fibrillation, fatal √ Over 4 amps heart paralysis; severe burns. Usually caused by >600 voltsBasic Electrical Safety

  13. 13. The Bhopal disaster or Bhopal gas tragedy was an industrialdisaster that took place at a Union Carbide pesticide plant in theIndian city of Bhopal, Madhya Pradesh. At midnight on 3December 1984, the plant released an estimated 42 tonnes oftoxic methyl isocyanate (MIC) gas, exposing more than 500,000people to MIC and other chemicals. The first official immediatedeath toll was 2,259. The government of Madhya Pradesh hasconfirmed a total of 3,787 deaths related to the gas release.Others estimate 8,000-10,000 died within 72 hours and 25,000have since died from gas-related diseases.

  16. 16. Unsafe Condition Insufficient workspace lighting. Excessive noise. Slippery or unsafe floor. Extreme temperature exposer. Inadequate protection when working with hazardous material. Unstable structure. Electrical problem. Machine malfunctioning or failure.R.Sangwan 17
  17. 17. Unsafe Acts Actions or failure to act which result in injury. Employee negligence. Organizational Error. “Live as if you were to die tomorrow. Learn as if you were to live forever.”R.Sangwan 18

Safety in Industry Safety in Industry  Safety means protection of Humans Plants & Machinery Surrounding Environment  Gains obtained by ignoring safety aspects are for short terms and not sustainable. “Developing and providing Sustainable Technologies results in Sustainable Development and improvedR.Sangwan Profits.
  19. 19. Prevention Works management should control major hazard installations by sound engineering and management practices. good plant design, fabrication and installation, including the use of high-standard components. regular plant maintenance; good plant operation; good management of safety on site; regular inspection of the installation, with repair and replacement of components where necessary.R.Sangwan 20
