  1. Safety Topic – H2S Awareness

  2. Safety Topic – H2S Awareness Volcanic fumes kill six Indonesian teenagers JAKARTA | Mon Jul 9, 2007 6:04am BST (Reuters) - Poisonous sulphur fumes from an Indonesian volcano just outside the capital killed six school children on a camping trip on the mountain, police said on Monday. Indonesia has the world's highest number of active volcanoes, and hiking and camping on volcanoes are popular pastimes. The forested Salak mountain one hour south of the capital is a favourite of young Jakartans. The six teenagers were part a group of 20 high school students from Jakarta on a camping trip who climbed to the rim of the crater, which is normally out of bounds for hikers, police officer Thomas Alexander said. One of the students was found dead with foam on his mouth, a strong indicator of sulphur poisoning, Alexander said. "The teens were playing around the fume-filled crater and inhaled the poisonous fumes," Alexander told Reuters. Some of the other students were unconscious but were immediately brought from the 2,180-metre (7,152 feet) peak to the nearest hospital. Sabar Jaya, a hospital official in the nearby city of Bogor, said no autopsy was performed as families decided to take the bodies home right after they arrived in the hospital. "We checked the corpses, there were no bruises or wounds. We believe the teens were poisoned by the crater's sulphur fumes," Jaya said.

  3. Going on a School Field Trip to Tangkubang Perahu?

  4. Oh Yeah, by the way: Hydrogen Sulfide Gas is a toxic (poisonous) gas that can kill you the first time you breath it!

  5. What is H2S? H2S is naturally occurring chemical produced by bacteria as it decomposes organic material. It may develop in low oxygen environments, such as, sewers, swamps and polluted water.

  6. It is a natural Product of Decay or Putrefaction You may find H2S in: Dairies Breweries Chemical processes Geothermal exploration Fisheries Tanneries 72 different Industries

  7. Physical Characteristics Color – Clear/Transparent Odor – Sweetish taste, unpleasant odor; described as rotten eggs. 7

  8. Vapor Density The weight of a gas as compared to air. Air = 1 H2S = 1.189 @ 32F 19% heavier than air 8

  9. Hazardous Characteristics Flammable 0% 100% 4.3% BURN RANGE LFL 46% UFL 1% = 10,000 PPM RICH LEAN 9

  10. Auto Ignition Temperature Hydrogen Sulfide will automatically ignite at 500 0F End of lit cigarette – 1400 0F Diesel exhaust – 600-2400 0F 10

  11. Hazardous Characteristics Toxic H2S is the second most toxic gas known to man. The most toxic is Hydrogen Cyanide PEL of H2S = 10 ppm PEL of HCN = 10 ppm 11

  12. Target Organs Eyes Lungs Nose Liver 12

  13. Notify Schools and other groups about the danger • I have notified Jakarta International School • Have provided Monitors and Training for the Chaperones Personal Monitors 13
