  2. 2. Location of accident and time schedule of scenario• Saint-Romain en Jarez, village located about 30 km from St-Etienne (France, LoireDepartment), about 1000 inhabitants• 2 October 2003 , timetable of events 16h02 : fire brigade called for a farmhouse fire, 16h24 : arrival of fire brigade : facing a warehouse fire 17h12 : explosion occurrence• Measures taken in the emergency• 3 October : safety perimeter implemented by authorities afterthe explosion (300 m at first, reduced to 100m by 6 Octobermorning)• 5 October 2003 , end of evening : fire declaredextinguished
  3. 3. Casualties and structural damage 26 casualties including 18 firemen (3 of which sufferinginjuries compromising life), 3 policemen et 5 civilians 82 houses suffering structural damage of varyingseverity

  6. 6. INERIS involvement intofirst response to the “crisis”• Arrival on site on 3 October 2003, by16:30• Damage inspection and recording of observations,compiling information, providing on-site support toemergency teams being there to manage the emergency,….• Presence on site maintained up to 7 October.
  7. 7. First statements from damage observations and records• 30 (among higher number of ) damage single inputs(observations) being used in the first analysis regardingthe characterization of the explosion strength, about location of nearest dwellings : 60 m far from the warehouse, damage observed as far as 650m far from the warehouse significant damage limited to some 300m to 600 m very serious damage to structures : up to 150m

  10. 10. Gymnasium - 100 m
  11. 11. Estimation of ‘ TNT equivalent ’ of the explosion fromobserved damagePressure effects deducted from observed damage, then use of charts of‘hemispheric loading’ : referring to methodology used for theinvestigation of the Toulouse accident,Result : 80 kg to 160 kg of TNT equivalentif detonation related to AN, then quantity in agreement with observationis within the range :160 kg to 533 kgwith proportionality rule from Circular of 21 January 2002:1600 to 5330 kg of material, initially.Notice : estimated quantity of AN fertilizer : 3 to 5 tons.
  12. 12. On the missile effect• 26 missile elements identified wall lining elements : no use in the analysis as they haveexperienced significant deformation before explosion due to thepreceding fire, concrete scraps, structural elements :• beam type ‘IPN 120’, 6 m of length, 70 kg of weight,• beam type ‘IPE 240’, 6m of length, 200 kg of weight,• sectional steel pieces,projection of scraps up to 800m,IPE 240 beam elements : displaced some 250mIPN 120 beam elements : displaced 310m to 350 m
