Re:An Fatal Accident that could have been prevented-Please Read!.

[Guest guest]

Gents It is one of the frequently occuring fatality in H2S Facilities(Especially in GULF most of the oil wells and gas production stations contain H2S), please be aware of the hazard and act in-front on such hazardous gas. REMEBER H2S IS A SILENT KILLER-----IT WILL INSENSITIZE YOUR SMELL IN CERTAIN CONCENTRATION AND WILL TAKE YOU TO DEATH... Many Thanks Mr. SHADVANI on sharing this report and alert, safety professionals please cascade this alert and learning's down line to your team.

This incidenceoccurred in "Proson" or "Prachi" Chemicals Pvt. Ltd. Khopoli, Dist. Raigad.Out of the two fatal cases, one was a third Shift Supervisor, Mr. SandeshWadekar, age 27 and the other a worker, Mr. Rajendra Mhatre, age 32. Thosewho are in critical condition are Mr. Gopal Yadav (27) and Mr. Sachin Patil(22).As per the Police statement, Mr. Wadekar and Mr. Mhatre wanted to find outthe source of abnoxious smell that started when there was a rain duringnight shift. Both of them went to storeshed where chemicals were stored.When they opened the door of store shed to enter inside, both of themcollapsed due to inhalation of

gas.It was reported that Phosphorus Pentasulphide was kept in open drums andwhen the rain water from leaking roof came in contact with PhsphorusPentasulphide, the Toxic gas was released.I have down loaded the MSDS of Phosphorus Pentasulphide and after goingthrough the same, the cause of deaths is very clear. Once PhosphorusPentasulphide comes in contact with water, it generates Hydrogen SulphideGas, which is extremely toxic and although in small percentage in air itgives a smell like rotten eggs, in higher concentration in air it isodourless! Thus when a person inhales higher concentration of H2S, heimmediately collapses because of central Nervous system failure.The above Accident was avoidable. Apparently, the Supervisor and workerwere not aware about the Dangerous properties of this chemical which theyhad in their factory. If they had known the "Incompatibility" data ofPhosphorus Pentasulphide, they

would have ensured not to keep this chemicalin open drums in stores. When they got a smell of rotten eggs, they shouldhave known that it is a smell of H2S and if they knew the dangerouspropertis of H2S, they would have worn the Personal Protective Equipmentlike either SCBA OR Supplied Air Respirator and only then they would havetried to open the door of Stores shed.It is not known whether this company had SCBA or Suppliede Air Respiratorswith them. It is also not known to us that whether the supervisors andworkers were given Awareness training about handling and storage ofHazardous Chemicals used in their factory.I have attached MSDS of Phosphorus Pentasulphide for your record. Pleaseforward this to your friends in Chemical Industry, who may be usingPhosphorous Pentasulphide and tell them to read carefully about itsdangerous properties and incompatibility with other chemicals.This couldsave many more precious

lives.Regards,Regards,SURESH HADVANIDy.

gray to yellow-green crystalline.Danger! Reacts with water to form hydrogen sulfide, sulfur dioxide, and phosphoric acid. Flammable solid. Water-reactive. Causes severe eye and skin irritation. May ignite or explode on contact with moist air. Harmful if inhaled or swallowed. Causes respiratory tract irritation. Stench. May cause central nervous system effects. Target Organs: Central nervous system, respiratory system, eyes, skin. Potential Health Effects Eye: Contact may cause severe eye irritation and possible eye damage. Skin: Causes severe skin irritation. Ingestion: Harmful if swallowed. May cause irritation of the digestive tract. Inhalation: May cause respiratory

tract irritation. Vapors may cause dizziness or suffocation. Inhalation of high concentrations may cause pulmonary edema. Higher exposures may cause the loss of sense of smell (anosmia). Inhalation overexposure may lead the CNS effect such as: headache, dizziness, weakness, confusion, sweating, nausea, and vomiting. Higher levels can cause seizures and death. Chronic: Prolonged exposure to hydrogen sulfide may result in pulmonary edema. Section 4 - First Aid Measures Eyes: Immediately flush eyes with plenty of water for at least 15 minutes,

occasionally lifting the upper and lower eyelids. Get medical aid imme diately. Skin: Get medical aid. Flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Ingestion: Do not induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately. Inhalation: Remove from exposure and move to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. Notes to Physician: Treat symptomatically and supportively. Section 5 - Fire Fighting Measures General Information: As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Vapors may form an explosive mixture with air. Vapors can travel to a source of ignition and flash back. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Will burn if involved in a fire. Water Reactive. Material will react with water and may release a flammable and/or toxic gas. Containers may explode in the heat of a fire. Flammable solid. May ignite or explode on contact with steam or moist air. Dangerous fire hazard in the form of dust when exposed to heat or flame. Extinguishing Media: Use dry sand or earth to smother fire. Water may be

ineffective. Do NOT use straight streams of water. DO NOT USE WATER OR FOAM. For large fires, use dry sand, dry chemical, soda ash or lime or withdraw from area and let fire burn.
