Prevention This map is common, you will see it again Risk is a combination of HAZARD Severity and FREQUENCY or LIKELIHOOD Mitigation
Risk Review Requirements The risk review process has to be determined • by all relevant stakeholders/departments of the organisation • in writing (company guideline) • shared with authorities etc. • defining the risk review team (multi-disciplinary including operator level) • defining milestones for and different levels of risk review (e.g. Design phase, pre-commissioning, pre-start up, changes, etc)
Design, Build and Operate How the project mgr. understood it How it was planned by the engineer How it was implemented by the technicians How the consultant interpreted it What the client ordered What the client really wanted What was charged To the client What was subject of the service agreement How it was documented How it was eventually built
Hazard Identification Operation hazards • eg. „classical“ EHS-hazards, loss of production, ... All hazards have to be identified comprehensively and systematically ... Network hazards • eg. failure of utilities, supplies, transportation ... Environmental hazards • eg. natural hazards, adjacent plants and traffic ways, ... Environmental vulnerability • eg. densely populated areas/buildings, natural reserves, ... Terrorist threats • eg. plant vulnerability, neighbourhood/environment sensitivity, company image, ... ... by e.g. “What if”, checklists, HAZOP, FMEA etc.
Risk Assessment Risk is a combination of hazardSeverity and Likelihood or frequency, often expressed as R=f(S,L) • Severity may be determined by • Gas dispersion in combination with criteria for human effects such as: • ERPGs (Emergency Response Planning Guidelines) • AEGLs (Acute Exposure Guideline Levels) • Explosion Overpressure and Fire radiation effects using tools such as: • TNO methodology • FLACS • Likelihood may be estimated by • expert opinion/experience • databases for failure frequencies • (semi-) quantitative assessments (risk graph, fault or event trees etc.) • Assessment of safety barriers and mitigation (e.g. “bow tie” diagram, Layer of Protection Analysis = LOPA)
Community Emergency Response Plant Emergency Response Physical Protection e.g. Relief Devices Safety Instrumented System preventative action Critical Alarms and Operator intervention Basic Process Control System, Operating Discipline / Supervision Plant Design integrity The LOPA “Onion”
LOPA criteria -1- Initiating events • Control system failures • Human error • Piping and equipment failures • Interruption of utilities (e.g. Cooling) Enabling Events/conditions • e.g. proportion of time when hazard may be present Independent layers of protection • Basic Process Control System (possibly) • Alarm and operator response • Relief systems • Safety Instrumented Systems • Other qualifying Safety Related Protection Systems • Need to independent, effective, tested, audited
LOPA criteria -2- Conditional Modifiers • Weather conditions • Probability of ignition • Probability of ignition leading to explosion • Probability that person(s) will be exposed • Probability that an exposed person will suffer a particular harm • May be difficult to justify and evaluate Mitigation (right hand side of bow tie) • Fire protection • Emergency Response • Water curtains • Secondary and tertiary containment • etc
‘Tolerable’ frequencies for events • What risk can we tolerate? • Frequency for an event of a given severity (injury, environmental insult etc.) • Users need to specify but aim to meet or exceed (do better than) regulator requirements • The chosen tolerability becomes the target for risk management sometimes called ‘Risk Governance’ for the company (usually Individual or Societal Risk) • Data and guidance available for injury/fatality and environmental effects
Tolerability Data (Fatalities) (Buncefield LOPA Guidance Dec 2009, final report from U.K. HSE) ALARP = As Low as Reasonably Practicable

Risk Assessment has to be adopted to the needs LEVEL 1: PROCESS HAZARDS ANALYSIS Should be done by plant based people They then have a better understanding of the risks and possibly how they may be reduced Level 1: PROCESS HAZARD ANALYSIS LEVEL 2: RISK REVIEW Specialist help from e.g. Process Engineering or Process safety function at site – should include Plant based people in the team Level 2: RISK REVIEW LEVEL 3: ENHANCED RISK REVIEW Specialist help from e.g. Process Engineering or Process Safety function within Corporate – should include Site and Plant based people in the team Level 3 ENHANCED RISK REVIEW LEVEL 4: QUANTITATIVE RISK ASSESSMENT Specialist help from external expertise. Owner needs to define scope and data. critique outcome. L4:QRA
Measuring Process Safety Performance: Process Safety Indicators (PSI) reporting levels Large loss of primary containment (LOPC) event Small loss of primary containment event Challenges to the safety system Operating discipline & management system
Thresholds for Loss of Containment becoming a PSI Cefic (European Chemical Industry Council) suggestion based on GHS classification

Management of Remaining Risks Communicate remaining risks • to staff (operating procedures, training, drills, …) • to external stakeholders (customers, neighbours, authorities – but careful regarding security risks!) Mitigate consequences • Internal emergency planning (above all organisation, equipment, drills) • Cooperation with external services (neighbouring plants, public services) Important: ability to react fast! The bigger a corporation, the higher the expectations even for small sites
Crisis Management Systems: can the unpredictable be planned? Define as much as possible in advance, because ... • ... crisis always happen at the wrong time and place • ... your regular organisation is not sufficient to handle crisis • ... all resources of the whole company have to be available in due time • ... public, media and authorities expect professional handling of crisis, too
Emergency Preparedness Accidents may happen even in most modern plants. They cannot be planned, but they should be considered. • Cover all relevant scenarios in the emergency plan • Assign responsibilities rather than regulating details • The emergency organisation is different from the normal organisation, but has to be empowered to use it • Adjust the emergency organisation to the dimension of the incident (e.g. “blue, yellow, red alert”) • Clearly document all available resources (site, company, neighbouring sites, authorities, ...) for the different scenarios. Ensure that they can be used in emergencies (e.g. co-operative agreements) • Train your people and run exercises • Before you rely on off-site resources, consider the time until availability • Industrial zones with many companies close together need special attention (“domino-effects”)
Mock Drills Major incidents hopefully become less frequent. This makes drills even more important ... • ... to train seldom used procedures • ... to reduce mental stress during incidents • ... to optimise emergency- and crisis- management • ... to make sure that necessary resources are available • … to de-brief after exercise, act on results
Emergency Response The basic principle: the faster and more effective the initial response, the smaller the consequences for men, environment and economy. • Provide the infrastructure for fast response (fire brigade, emergency control room, availability of key personnel, etc.) • Encourage immediate reporting of incidents (not to wait until own efforts failed ...), do not blame for false alarms • If the fire brigade is (partly) staffed by operators be aware of the risks of understaffed production • Better start with a higher level of alarm (worst case assumption) and grade it down later than vice versa • Notify and involve public fire brigades and authorities as soon as possible • Analyse every incident and the response to improve the emergency organisation without blaming anyone

The Role of Authorities The cooperation between authorities and companies at an incident depends on their cooperation before the incident. • Open communication about risks and safety measures on a regular basis (e.g. in a local or regional committee) builds up trust which is urgently needed during emergency response • Authorities need to know about the possible scenarios for major accidents to do their own preparations • Authorities should have clear rules about their responsibilities in handling major incidents to avoid conflicts between the different agencies (e.g. labour safety, environment, civil protection, police etc.) • Mitigation of consequences should come first, legal prosecution of individuals responsible for the incident later
Neighbours, Journalists and Environmentalists The basic issue: Neighbours and the general public share the risks of industrial sites, but not necessarily the benefits. • Communication of relevant risks has to be done openly and in an adequate form (“not scientific”) prior to incidents (e.g. “neighbourhood councils”, brochures, ...) • to build up trust in the competence of the company to handle risks • to enable the neighbours to react adequately during an incident • The response of neighbours etc. to incidents is strongly influenced by the company´s response to requests and complaints prior to the incident • Fast and open information after an incident is crucial • Fears and worries of neighbours etc. have to be taken seriously even if they are based on emotions rather than science • On the long term, conflicts with neighbours etc. endangers the “licence to operate”
Crisis Communication Sometimes crisis communicatiuon becomes a crisis of communication!
Outline iDRM Approach in Europe 1 2 Risk Management Principles 3 Best Practice of Emergency Management 4 Conclusions
Conclusions • Investing in safe and eco-efficient plants pays off at least on the long term • The (remaining) risks of industrial plants can be assessed and are the basis for scenarios for emergency planning • The knowledge and experience of the operators should be used by all means • Risks should be communicated as well as benefits to all stakeholders, esp. the neighbours • The resources for emergency response (manpower, equipment, communications, organisation etc) have to be planned in advance and readily available in case of an incident. People usually accept the risk of a chemical/pharmaceutical plant, but not incompetence in handling it • Authorities should involve themselves actively in emergency planning, balancing this out with their law enforcement duties • Combined efforts will definitely lead to safer and more accepted plants, as the figures from Germany may show
