  1. CHEMICAL SAFETY

  2. CHEMICALS CHEMICALS HAVE AN INDISPENSIBLE ROLE TO PLAY IN FULFILLING THE BASIC NEEDS OF PRESENT DAY LIVING.THE FOLLOWING HAZARDOUS CHEMICALS GO INTO MAKING HOUSE HOLD PRODUCTS

  3. CLASSIFICATION OF CHEMICALS IS 1446-1959 • CLASS1 EXPLOSIVE ORANGE • CLASS2 LIQ-GASES GREEN • CLASS3 FLAMMABLE LIQUID-RED • CLASS4 FLAMMABLE SOLID-R& Wst • CLASS5 OXIDISING YELLOW • CLASS6 TOXIC WHITE • CLASS7 RADIO ACTIVE YELLOW&W • CLASS8 CORROSIVE BLACK&WHITE • CLASS9 MISC -

  4. TOXICITY OF CHEMICALS • 1.TRAUMIC – BODILY AFFECT • 2.ALLERGIC – DERMATITIS • 3. CARGENOGENIC – CANCER PRODUCE • 4.TARATOGENIC –GENETIC DEFORM • 5.MUTAGENIC – TUMOUR FORMING • 6.NARCOTIC – SLEEP INDUCING • 7.SIMPLE ASPHYXIANT –O2 DEPLETION • 8.CHEMICAL ASPHYXIANT- -DO-

  5. MODE OF ENTRY • INHALATION- THROGH NOSE GASES, DUST, AEROSOLS,VAPOUR, MIST, SMOKE • INGESTION – THROUGH MOUTH LIQUID AND SOLID CHEMICALS, • SKIN ABSORPTION- THROUGH SKIN LIQUID, VAPOUR & GASEOUS CHEMICALS

  6. STORAGE OF CHEMICALS • AVAILABLE WHEN REQUIRED • NOT DETORIORATED INQUALITY • NOT CONTAMINATED WITH OTHER CHEMICALS • NOT ENDANGER TO LIFE & PROPERTY • NOT LOST BY LEAK OR SPILLAGE

  7. SAFETY ASPECTS OF STORING CHEMICALS • STD DESIGN OF STORAGE VESSEL • STATE OF CHEMICAL TO BE STORED • QUANTITY OF CHEMICAL STORED • PACKING & CONTAINERS • ARRANGEMENT TO MEET EMERGENCY • SPILLAGE CONTROL • PROTECTION AGAINST FIRE • PPE REQUIRED WHILE HANDLED

  8. NFPA CLASSIFICATION OFCHEMICALS • HAZARD CODE FOR CHLORINE CODE HAZARD RANKING R= REACT IVITY F=FLAMMABILITY H= HEALTH HAZARD F 1 R 3 0=NO ACTION 1=LOW ACTION 2= MEDIUM ACTION 3= HIGH ACTION 4= EXTREME ACTION H 3 2

  9. SOLID CHEMICALSTORAGE

  10. LIQUID CHEMICALS STORAGE

  11. GASEOUS CHEMICAL STORAGE

  12. LIQUID CHEMICAL TRANSFER

  13. CHEMICAL SAFETY • TLV= The concn. of a toxic chemicalin ppmormg/m3 for a worker to work 8 hrs in a day with out any adverse effect even repeated exposure • STEL= Continuous exposure for 15 mts with out any adverse exposure

  14. Chemical safety • TLV-C* = Ceiling is the concn for 8 hrs but not to be exceeded momentarily • TLV -MAC = Max.allowable concn for momentary exposure during emergency. • IDLH= Immediately dangerous to life and health. The concn to kill even 10 mts exposure

  15. Chemical safety • Toxicity of chemical • Acute = Immediate action • Local = Affect the particular area • Systemic = Affect the system in the body • Chronic = affect after long time exposure

  16. APPLICATION OF TLV • FOR INDIVIDUAL GAS • TWA = t1c1+t2c2+t3c3..tncn=<TLV 8 t= sample time, c= concn. Of chemical FOR MIXURE OF GASES TWA =c1/t1+c2/t2+c3/t3…cn /tn=<1 t= TLV, c= concn of chemical

  19. TRANSPORTATION OF HAZARDOUS CHEMICALS BY ROAD • REQUIREMENTS AS PER SAFETY NORMS • 1.TRAINED DRIVER WITH HELPER • 2. MSDS OF THE CHEMICAL • 3. TREM CARD • 4. BREATHING APPARATUS • 5. FIRE EXTINGUSHERS SPECIFIED • 6 DESTINATIONS ADDRESS &Ph. Nos • 7 CELL PHONE FOR COMMUNICATION • 8 BUCKET& JERRY CAN WITH WATER • 9 FIRST AID BOX WITH MADICINES

  20. INDL .GAS CYLINDERS COLOUR CODE

  21. CHEMICAL HAZARD IDENTIFY • 1. BY COLOUR AND ODOUR • 2. BY IRRITATION & REACTION • 3.BY ANALYSIS & MONITORING • 4. BY FORMULA & STRUCTURE • 5. BY SENSATION • ODOURLESS CHEMICALS ARE MORE DANGEROUS THAN ODOUROUS CHEMICALS

  22. STATUTORY NORMS FOR HAZARDOUS CHEMICALS • MENTION THE TECHNICAL NAME • PROVISION OF WARNING SYNBOLS • LABELLING ON THE PACKAGE • PROPER PACKAGE WITH SEALING • MSDS OF THE CHEMICALS • POSSIBLE HEALTH HAZARDS • ANTITODE FOR THE CHEMICALS

  23. HAZARD CONTROL • QUANTITY OF INVENTORY • AVOID SPILLAGE • SPECIFIED THE CHEMICAL STORAGE • SPILLAGE RECLAIMATION • LEAK ARRESTING • DEVELOP DISPERSION MODELLING • ONSITE/OFF-SITE EMERGENCY PLAN • SAFE STORAGE & HANDLING

  24. CHEMICALS IN STERLITE INDUSTRIES • Sulphur-di-oxide • Sulphuric Acid • Phosphoric Acid • Rock phosphate, • Hydrogen Fluoride, • Hydrogen Sulphide • Hydrofluoric Silicic Acid • IsoPropyl Alcohol • Arsenic , • LPG,HSD,LSHS,FO

  25. CHEMICAL SAFETY • MSDS PREPARATION • EMERGENCY PREPAREDNESS PLAN FOR CHEMICAL RELEASE • MOCK DRILL TO BE CONDUCTED ON THE PLAN PERIODICALLY • PROPER PPEs ARE TO BE KEPT READY FOR USING DURING EMERGENCY • SAFE GUARD THE PUBLIC NEARBY
