Requirements /1

• Written form
• Fully readable (stand alone)
• Description of establishment and surroundings
• Precise description of dangerous substances (CAS,
  IUPAC, toxicologicalphysical properties, ...
• Max. capacity of dangerous substances
• List and scheme of activities
• Inventory of technical installations and a
  corresponding map
• Description and drawing of technical
  installations
• Description and scheme of processes and
  conditions of storage and handling

4
Requirements /2

• Hazard analysis document
• Identification of safety-relevant technical
  installations
• Identification of sources of hazard
• Installation proper
• Human failures
• Failure of process control devices
• Loss of containment (corrosion, undetected
  leakages, ...)
• Deviation of process-parameters
• Interruption of energy, pressure air, cooling,
  ...
• Internal transport, internal Domino effect
• External sources (extreme temperatures, wind,
  lighting, earthquake, flooding, sabotage ...)
• Methods systematic, broadly acknowledged (HAZOP,
  FMEA, LOPA, What-if)

5
Relations of hazard analysis
Relevant properties- physical- chemical-
toxic- process conditions
Initiating event- leakage- operational
failure- deviation of process parameters-
maintenance failure
Scenario- release of dang. substance- fire,
explosion
Possible severity of damages
6
Requirements /3

• Description of measures general demonstration of
  the criteria for sizing and evaluation of safety
  measures
• Process control systems
• Fire- and explosion fighting measures
• Limiting measures (water curtain, scrubber ...)
• Rapid or automatic shut down systems
• Fail-safe devices
• Inertisation
• Pressure release devices
• Alarming systems (i.e. gas detection)

Improvement of measures Increase of level of
safety
Scenarios- release of dang. Substance- fire,

Substitution of dangerous substances New process

Possible severity of damages
Demonstration and evaluation of measures
8
Requirements /4

• Consequence evaluation
• Purpose basis for
• Establishing the internal emergency plan
• Determination of public to be informed
• Land Use Planning
• Domino effects
• Only passive safety-measures are taken into
  account
• Internal emergency plan with connections and
  interfaces to the external emergency plan
• Summary of and reference to the SMS

9
Internal Emergency Plan

• Basis of the IEP is the consequence evaluation
• Necessary content of the IEP see Annex III of
  Seveso II Directive
• The IEP consists of two completely different
  parts with different aims
• Preparedness plan (before the accident)
• Determination of persons authorized to set
  emergency procedures in motion
• Determination of persons in charge of and
  coordinating the on-site mitigatory action
• Determination of the person with responsibility
  for liaising with the authority responsible for
  the external emergency plan
• Define degrees of the accident (often 4 just an
  incident, accident with internal response only,
  accident not to cope with internal response
  external help needed, catastrophic)
• Description and map of areas likely to be
  endangered
• Description of internal technical and
  organisational measures
• Assessment of these measures in qualitative and
  quantitative respect
• Floating oil barriers available, sufficient fire
  fighting water available, redundant energy supply
  for pumps, fire water retention, testing
  equipment to identify the released substances,
• How many internal persons needed for appropriate
  action, what kind of training needed,
• Information about substances
• Response Plan (after the accident)
• Alarming procedures depending on the degree of
  the accident
• Determination of the measures which have to be
  taken depending on the kind and the degree of the
  accident
• Description and map of the site containing
  specific information for rescue services
  (entrance for external fire fighters, position of
  hydrants, storage for oil barriers and oil
  binding agents, )
• Information about substances, insofar this
  information is relevant for mitigatory actions
