Safety In Storage / handling / Transportation Of Chemicals. By Bimal Chandra Das

  1. 1. Safety In Storage Of Chemicals Storage tank should be Constructed on sound foundation & protected against corrosion Be clearly marked & labeled to avoid chance of confusion Be located at cool & dry place away from heat Provided with dyke walls & permanent stairs (liquid chem.) 1B C DAS
  2. 2. Safety in Storage of Chemicals Incompatible chem. be stored away from each others Periodically check storage tanks for leaks / spills Maintain high standard of housekeeping in storage area Prohibit eating, drinking & smoking where haz-chem are stored Workers be trained in handling emergencies (fire, gas, spills etc.) 2B C DAS
  3. 3. Safety in Handling of Chemicals Attempt to minimize manual handling Solid chemicals be handled with lifting m/c or conveyors Liquid chemicals be handled by pumps & pipelines Pipelines to have specific color code / mark 3B C DAS
  4. 4. Safety in Handling of Chemicals Static electricity hazard to be taken into consideration Valves to be at accessible location to control / stop the flow Pipelines to be checked / inspected to detect leakages regularly Ensure use of PPE’s during handling chemicals / operating valves & maintain good personal hygiene standards 4B C DAS
  5. 5. Safety in Transportation of Chemicals Labels or notices to be prominently affixed on vehicles Well designed, properly constructed/ maintained container with good operating valves to be used Engine exhaust to be provided with spark arrester Remote control facilities to be made for master valves 5B C DAS
  6. 6. Safety in Transportation of Chemicals Tanker to have proper earthing facility, fire extinguishers & first-aid kits Drivers/ operators to be trained & should have knowledge of chemicals hazards/ risk involved in them Chemical pipeline maintenance/ repair to be taken up with approved shutdown & standard permit-to-work 6B C DAS
  7. 7. Properties of Ammonia Boiling Point : -33.40 C Vapodensity 0.60 Physical state Liquified Compressed gas Appearance & Odour Colourless, Strong Pungent odour Explosive limits 16 - 25 % Ignition Temp. 6510 C TLV 25 PPM Inhalation Routes of Entry skin, eyes Effects of Exposure 700 PPM - eye irritation, 5000 PPM - death. Contact of liquid with skin , freezes the tissues causes Caustic burns PPE’s Use Rubber boots, safety goggles, gas masks & Protective clothing. 7B C DAS
  8. 8. Properties of Benzene Boiling Point 80O C Vapour density 2.77 Physical state Liquid Appearance & Odour Colorless, Aromatic odour Explosive limits 1.4 - 8 % Ignition Temperature 5620 C TLV 10 PPM Routes of Entry Inhalation, Ingestion, skin, eyes Effects of Exposure •Repeated contact with skin causes dermatitis; Inhalation causes headache, dizziness, unconsciousness & Leukemia PPE’s •Use canister gas mask, goggles/ face shield, rubber or plastic gloves 8B C DAS
  9. 9. Properties Of Oxygen Boiling Point -182.90 C Vapour density 1.43 Physical state Liquified compressed gas Appearance & Odour Colorless, Odorless Explosive limits Not pertinent Ignition Temperature Not pertinent TLV Not listed Routes of Entry Inhalation, skin, eyes Effects of Exposure Inhalation of 100% O2 causes nausea, dizziness, irritation of lungs & collapse Liquid contact cause frost bite of skin PPE’s Use goggles/ face shield, insulated gloves apron etc 9B C DAS
  10. 10. Instruction for Safe Loading/ Unloading Road Driver: Position the vehicle, apply brakes, Shut- off engine & Lights Be present throughout unloading Check disconnection of hoses & Earthing, removal of wheel chokes before driving away 10B C DAS
  11. 11. Operator: No smoking / naked lights in the area Ensure correct positioning of truck, put wheel chocks and make earth connection. Check condition of hose pipe, valve, flange, gasket etc., Check & make sure the tanker/ storage tank can hold the load Ensure no leakage hose connection Material transfer by opening valves in proper sequence Remain in attendance throughout unloading Close valves in proper sequence, disconnect hose pipe, remove wheel chocks & earth connection before moving tanker Instruction for Safe Loading/ Unloading 11B C DAS
