• Hazard Identification (line from tank to pump) HAZOP technique, examine
deviations for :
oNO FLOW, LESS FLOW
oMORE TEMPERATURE
o LOSS OF CONTAINEMENT

This Project is funded by the European Union
Project implemented by Human Dynamics Consortium
• Risk analysis on consequence, effects to people (cont.) Tank BLEVE accident in LPG
installation located within industrial park, close to village o Very severe effects : 1500 TDU, 3rd degree
burns in more than 50% of exposed population
o Severe effects : 450 TDU, 3rd degree burns in 1% of exposed population
o Mild effects : 170 TDU, 1st degree burns at significant part of exposed population
(TDU : (kW/m2)4/3. sec, be careful with units)
