Hazardous Materials

  1. 1. Hazardous materials<br />(HAZMATs)<br />
  2. 2. GHS<br />Abu Dhabi uses the Globally Harmonised System of Classification and Labelling of Chemicals (GHS) <br />The UN brought together experts from different countries to create the Globally Harmonized System of Classification and Labelling of Chemicals (GHS) to minimise confusion over labels.<br />The aim of the GHS is to have, worldwide, the same: <br /><ul><li>criteria for classifying chemicals according to their health, environmental and physical hazards; and
  3. 3. hazard communication requirements for labelling and safety data sheets. </li></li></ul><li>GHS<br />GHS uses:<br /><ul><li>Symbols & pictograms
  4. 4. Signal words, e.g. DANGER; WARNING
  5. 5. Hazard statements, e.g. fatal if swallowed
  6. 6. Precautionary statements (see next slide)</li></li></ul><li>Precautionary statements <br />Precautionary statements are also required by the GHS to describe the following:<br /><ul><li>Prevention
  7. 7. Response (in case of accident)
  8. 8. Storage
  9. 9. disposal</li></li></ul><li>Precautionary statements <br />
  10. 10. LD50 & LC50<br />What does LD50 mean?<br />LD stands for &quot;Lethal Dose&quot;. LD50 is the amount of a material, given all at once, which causes the death of 50% (one half) of a group of test animals. The LD50 is one way to measure the short-term poisoning potential (acute toxicity) of a material. <br />What does LC50 mean?<br />LC stands for &quot;Lethal Concentration&quot;. LC values usually refer to the concentration of a chemical in air but in environmental studies it can also mean the concentration of a chemical in water. <br />For inhalation experiments, the concentration of the chemical in air that kills 50% of the test animals in a given time (usually four hours) is the LC50 value. <br />
  11. 11. Acute toxicity -Oral<br />
  12. 12. Pictograms are important in labelling HAZMATs<br />
  13. 13. Corrosive<br />
  14. 14. Harmful<br />
  15. 15. Toxic; may be fatal<br />
  16. 16. Unstable explosive<br />
  17. 17. Extremely flammable<br />
  18. 18. Gas under pressure; may explode when heated<br />
  19. 19. May cause breathing problems<br />
  20. 20. Toxic to the environment<br />
  21. 21. GHS uses 5 categories to show danger<br />
  22. 22. Code of Practice 15<br />Hazardous materials management<br />
  23. 23. CoP aims<br />Give practical advice to manage HAZMATs<br />Drive improvement<br />Address deleterious impacts of HAZMATs<br />
  24. 24. Intent<br />Reduce environmental harm<br />Encourage efficient use of resources<br />Enhance OHS<br />Identify roles & responsibilities of manufacturers, importers, suppliers, employees, employers & community re. HAZMATs<br />Introduce penalties for non-compliance<br />
  25. 25. Environment, Health & Safety Impact AssessmentEHSIA<br /><ul><li>Required prior to obtaining permit
  26. 26. IA must say how discharges will comply with CoPs (air, water, land & noise)
  27. 27. IA must describe plans for future rehabilitation of site</li></li></ul><li>HAZMATs Management indicators<br /><ul><li>Class 1 – health, safety, wellbeing
  28. 28. Class 1A – general provisions for HAZMATs management
  29. 29. Class 1B – specific provisions for HAZMATs management</li></li></ul><li>Class 1A management indicators<br />All HAZMATs to be classified according to GHS<br />
  30. 30. Manufacturers, Importers & Suppliers of HAZMATs must:<br /><ul><li>prevent or minimise waste
  31. 31. have permits
  32. 32. classify & label all HAZMATs
  33. 33. Store, handle, transport and dispose of all HAZMATs properly
  34. 34. prepare MATERIAL SAFETY DATA SHEETS (MSDS)</li></ul>http://avogadro.chem.iastate.edu/MSDS/methane.pdf<br /><ul><li>disclose ingredients to medics, Sector regulators and EAD</li></li></ul><li>Employers must:<br /><ul><li>label and maintain a register of all HAZMATs
  35. 35. carry out a risk assessment
  36. 36. ensure exposure standards are not exceeded
  37. 37. ensure routine health checks for employees and make records available
  38. 38. Keep all relevant records
  39. 39. Make MSDS available to employees
  40. 40. Train employees & provide safety equipment</li></li></ul><li>Employees must:<br /><ul><li>Comply with CoPs as much as possible
  41. 41. Inform the employer where non-compliance is evident</li></li></ul><li>EAD must:<br />Provide direction (GHS)<br />Ensure compliance with waste CoP<br />Establish lines of communication regarding HAZMATs with concerned parties and the community<br />Undertake inspections & audits<br />Penalise those who are non-compliant<br />
  42. 42. 1B Indicators<br />To be classified as:<br /><ul><li>Physical hazards, e.g. explosives; flammable substances; corrosive substances
  43. 43. Health hazards, e.g. carcinogenic, mutagenic, toxic
  44. 44. Environmental hazards, e.g. hazardous to aquatic environment</li></li></ul><li>Incidents involving HAZMATs must be reported<br />Transporters of HAZMATs must maintain written or e-records<br />EAD to develop an emergency response<br />
