Problems encountered: Unrealistic differences in results for specific type of accidents (dispersion of SO2 due to fire in fuel installations). Judgement necessary to assess who provides realistic estimation. Some scenarios were based on outdated IDLH values. New Emergency Zones calculated by primary data of concentration (table/graph) in Safety Reports) This Project is funded by the European Union Project implemented by Human Dynamics Consortium • Important !!! For EEP preparation (and implementation) the accident is considered as happened and can potentially escalate o Do not mix EEP with requirements to the establishment for additional prevention/mitigation measures. o Other regulatory procedures deal with this point This Project is funded by the European Union Project implemented by Human Dynamics Consortium • Collection of data on Authorities Big challenge to obtain data from several Authorities agencies Contradictory information available, need to check out data Hardest challenge to keep data updated This Project is funded by the European Union Project implemented by Human Dynamics Consortium • Collection of data for Area (mapping up to where ?) One guidance is provided by Emergency Zones extent ... but Emergency Zones must have been defined Emergency Zones are prone to uncertainty of consequence analysis. Additional area must be covered. Additional area required also for facilitating decisions on: o traffic control o access routes o selection of shelters after evacuation o etc. This Project is funded by the European Union Project implemented by Human Dynamics Consortium • Collection of data for Area (cont.) Approach adopted for wide area map: o Mapping up to radius of 150% of higher Emergency Zone (Zone 3) o Minimum case: 4 km radius around establishment o Typical scale 1:2.500-1:5.000 Approach adopted for close area map: o Mapping up to radius of 120% of higher Emergency Zone (Zone 3) o Minimum case: 2 km radius around establishment o Typical scale 1:25.000 This Project is funded by the European Union Project implemented by Human Dynamics Consortium • Collection of data for Area (cont.) Problems encountered: No central Authority for mapping data available Poor area maps available in Safety Reports, as typical maps available to public by State (usually Army Geography Service) were quite outdated In some maps, areas depicted in black (military installations or critical infrastructure installations such refineries) (the public eye in the sky –Google Earth - was not available at that time) In some areas close to borders, quite limited maps at all available, due to military restrictions This Project is funded by the European Union Project implemented by Human Dynamics Consortium • Collection of data for Area (cont.) Problems encountered: (cont) No unified GIS-background information available No special requirements for indication of vulnerable places in Safety Report maps, neither on mapping extent No organized collection of vulnerable places data by Authorities, contradictory information available Gathering of data required also area surveys and data verification This Project is funded by the European Union Project implemented by Human Dynamics Consortium • Collection of data for Area (cont.) Wide/Close area maps build by GIS application in which all cartographic background information were introduced, along with collaborating database (MS Access) in which information were stored for: o establishment (location of tanks/units, content, scenarios, emergency zones) o vulnerable places (location, contact information, capacities, working hours) o authorities agencies (location, contact information) This Project is funded by the European Union Project implemented by Human Dynamics Consortium • Extract of map developed Seveso sites Accident Locations (tanks etc.) This Project is funded by the European Union Vulnerable places Sports facilities Schools Elderly houses Public service Other Agencies Ministry Police Fire Brigade Health service Municipality office Army Other Road network Primary Secondary Other Project implemented by Human Dynamics Consortium • Accident Categories Categories selected based on top events (final accidents) included in Safety Report Generic list of top events expected : o Pool fire o Fireball (BLEVE) o Jet flame (only for pipelines) o UVCE (vapour cloud explosion) o Toxic dispersion No flash fire, as typically ignited before EEP can be activated No jet flame for vessels/tanks, as considered to lead to fireball This Project is funded by the European Union Project implemented by Human Dynamics Consortium • Accident Categories (cont.) For each category of top event, different scenarios included for : o tank farm (both tank and dike fire -if applicable-) o process units area o pipelines from/to establishment o movement facilities (road/rail tankers stations, ports) usually not for LPG depots, as accidents in road/rail tankers can trigger tank accident (even worse) This Project is funded by the European Union Project implemented by Human Dynamics Consortium • Accident Categories (cont.) For each scenario included, the worst-case one was examined based on : o consequence (protection zones) extent and o proximity to fence (affecting external area affected), especially if vulnerable objects are close and o worst case atmospheric conditions For large establishments (petroleum refineries, petrochemicals, chemical complexes), multiple worst-cases examined for different areas of establishments (due to different affected areas) This Project is funded by the European Union Project implemented by Human Dynamics Consortium • Accident Categories (cont.) Multiple worst-case (BLEVE) example, refinery with LPG/propylene tanks at different areas of refinery This Project is funded by the European Union Project implemented by Human Dynamics Consortium • Accident Categories (cont.) Different worst-case scenarios examined for different toxics (for example in refineries : SO2 dispersion from tank fire, and H2S dispersion from failures in sulphur recovery units –Claus) Different worst-case scenarios examined for different storage types of same toxic (for example ammonia), due to inherent difference in dispersion mechanisms : o refrigerated gas o semi-refrigerated or pressure liquefied gases toxics This Project is funded by the European Union Project implemented by Human Dynamics Consortium • Accident Description Standardised generic description for accident in such type of establishment (very useful for general overview of accident characteristics) o Accident expression (causes, duration, evolution) o Effects to people/structures (qualitative) o Domino effects/escalation (qualitative) o Appropriate mitigation strategy/means/actions This Project is funded by the European Union Project implemented by Human Dynamics Consortium • Consequence estimation Scenario data o Substance involved o Equipment involved (dimensions) o Duration o Other scenario characteristics such as : BLEVE : fireball radius pool fire : flame length, angle atmospheric conditions, o Important assumptions (for example: full tank considered) This Project is funded by the European Union Project implemented by Human Dynamics Consortium • Consequence estimation (cont.)

Project implemented by Human Dynamics Consortium • Command and Control Typically, hierarchy structure and mission defined by legislation Major gap encountered: No scene (operations) commander (commander of all emergency responders in accident area) foreseen in legislation. Considered as absolutely necessary for coordination of actions in accident area between emergency responder teams (fire brigade, police, medical services etc.) This Project is funded by the European Union Project implemented by Human Dynamics Consortium • Command and Control Proposal for scene commander: Top officer of Fire Brigade on scene. Why Fire Brigade ??? Most probably the most knowledgeable from emergency responders on hazards from accident and potential escalation risks Operations Command and Control centres Central government (Civil Protection Secretariat premises) Regional (prefectural level where Prefectural Coordination Committee operates, prefecture premises) This Project is funded by the European Union Project implemented by Human Dynamics Consortium • Command and Control (cont.) Important issue to be considered : Local Operations Command and Control centre o Rather close to accident area, but in safe distance o To be used by : Scene Commander Emergency Response Team heads Representative of establishment Representative of Prefect and Representatives of Municipalities This Project is funded by the European Union Project implemented by Human Dynamics Consortium • Command and Control (cont.) Communication networks for : o between scene responder groups o from scene responder group to headquarters, o from scene area to Command and Control Centres Different radio communication frequencies for each emergency responder group on scene Common frequency in to be used only upon agreement This Project is funded by the European Union Project implemented by Human Dynamics Consortium • Public warning and information to the Public Predefined standard messages templates for : o simple warning (no protection measures required) scene responder groups o shelter in place instructions o preparation of evacuation o public evacuation order o schools evacuation order o medical services evacuation order o other vulnerable places evacuation order o end of accident message This Project is funded by the European Union Project implemented by Human Dynamics Consortium • Public warning and information to the Public (cont.) Example for shelter in place message From : •Date/time of send : __________________________________________________ •Contact phone : _______________________________________________________ •The Agency _____________has declared the area close to industry __________in state of emergency. •A ______________ has happened in the industry _____________ . In order to avoid exposure to danger, we ask you to keep indoors and to close doors, windows, air condition equipment and fans ___________________________________________________________________________ •This is addressed to all within a zone of radius of _____ m around industry _____________________, i.e. till _________________________________ •Please remain indoors till further instructions are provided. •Emergency responders have already been to the event location.

For any news, we will inform you promptly.. • The Author This Project is funded by the European Union Project implemented by Human Dynamics Consortium • Public warning and information to the Public (cont.) Additional instructions that could be provided for shelter in place : o Close all external and as many as possible internal doors o Close and lock windows o In case of fire or explosion, close windows and shutters, stay away from window in order to avoid injuries from glass fragments o Close all air conditioners (including air nitakes –if applicable), ventilation port (as in bathrooms), fans, cook hood extractors and any heating system o Seal as mush as possible any gas or holes with for wrapping materials (plastic, aluminum foil), waxed paper, adhesive tape o Close fireplace dampers This Project is funded by the European Union Project implemented by Human Dynamics Consortium • Public warning and information to the Public (cont.) Additional instructions that could be provided for shelter in place : (cont.) o Not to use elevator (action of sucking air from building external) o Perhaps better relocation to upper or lower floors (depending on case) o In case of dispersion water soluble substances, use of wet rug for even better protection (scrubbing inhaled air) This Project is funded by the European Union Project implemented by Human Dynamics Consortium • Public warning and information to the Public (cont.) Warning and information media : o Mass Media (TV, radio-essential when electric power supply is stopped in area) for general public o Telephone calls to vulnerable places within protection zones (by Prefecture or preferably by Police emergency service especially at early stage of accident). Regular update of information to vulnerable place must be foreseen. o Loudspeakers on vehicles if possible, and only as initial warning in area close to accident. o Door to door only for very close area and taking into account emergency responders protection equipment (i.e. no heat resistant uniform for police personnel). This Project is funded by the European Union Project implemented by Human Dynamics Consortium • Emergency Responders Safety Approach to establishment o At least 2 access routes proposed o Guidelines for approach included (for example, approach downwind/crosswind for toxics or for notignited LPG) Emergency responders safety equipment o Based on type of accident (thermal radiation, toxic) and typology of personnel safety equipment of Fire Brigade This Project is funded by the European Union Project implemented by Human Dynamics Consortium • Emergency Responders Safety (cont.) o Zone I : excludes all responders without protection equipment, as immediate death is expected. Typically affects police and medical service personnel o Zone II-III : for toxic dispersion, emergency responders should not enter without protective equipment or they should remain for limited time, as zones definition is set for exposure time of 30 min. Traffic control should be set outside Zone III This Project is funded by the European Union Project implemented by Human Dynamics Consortium • Short Action List Table with summary of actions and responsible agencies Nr Action Responsible 1 Early warning by establishment to Fire Brigade emergency service Establishment 2 Authorities Alert 1st level Verification of establishment alert Fire Brigade emergency service 3 Identification/verification of situation at site incident at Decision of initial protection actions and information to the public in close area Scene commander … …. … 25 Population return and transportation routes reopening Prefecture 26 Final accident report Prefecture Civil Protection office This Project is funded by the European Union Project implemented by Human Dynamics Consortium • Highly important issues • Keep updated all data (maps, installation, area, authorities) o Procedure must be established so that periodic review of EEP is carried out o Land use Planning and building permits must be connected with EEP, among others for update of EEP This Project is funded by the European Union Project implemented by Human Dynamics Consortium
