  • Hazard Identification (line from tank to pump)
    • HAZOP technique, examine deviations for :
      • NO FLOW, LESS FLOW
      • MORE TEMPERATURE
      • LOSS OF CONTAINEMENT

Risk analysis on consequence, Domino effects

    • Comment Domino effects from tanker BLEVE
slide8

Risk analysis on consequence, effects to people (cont.)

    • Tank BLEVE accident in LPG installation located within industrial park, close to village
      • Very severe effects : 1500 TDU, 3rd degree burns in more than 50% of exposed population
      • Severe effects : 450 TDU, 3rd degree burns in 1% of exposed population
      • Mild effects : 170 TDU, 1st degree burns at significant part of exposed population

(TDU : (kW/m2)4/3. sec, be careful with units)

slide9

Risk analysis on consequence, effects to people (cont.)

    • Comment on effects to population
    • Comment on access to site
    • Comment on effects to transportation routes
    • Consider emergency planning actions
