PREFACE This Philosophy defines the OMV Exploration & Production GmbH corporate policy on the design of Escape, Evacuation and Rescue (EER) facilities for onshore hydrocarbon production and processing facilities. The document specifies basic requirements and criteria, defines the appropriate codes and standards, and assists in the standardisation of facilities’ design across all onshore operations. The design process needs to consider project specific factors such as the location, production composition, production rates and pressures, the process selected and the size of the plant. This philosophy aims to address a wide range of the above variables, however it is recognised that not all circumstances can be covered. In situations where project specific considerations may justify deviation from this philosophy, a document supporting the request for deviation shall be submitted to OMV E&P for approval. Reference should be made to the parent of this philosophy, document number TO-HQ-02-001 for information on deviation procedures and Technical Authorities, general requirements and definitions and abbreviations not specific to this document.

EER DESIGN PHILOSOPHY EER facilities shall be designed in accordance with the general provisions detailed in ISO 13702, as applicable to onshore installations, and shall be based on the Escape, Evacuation and Rescue Assessment (EERA) for the plant. The provision of EER facilities should consider the following during the plant design:

8.1

•

Plant layout

•

Manning levels and the manning distribution

•

Internal communications – means of alerting personnel of a hazardous event or potential hazardous event

•

Escape Routes

•

Muster Areas

•

Means of personnel Evacuation, where appropriate

•

Means to affect Rescue and recovery of personnel

General Considerations The design and provision of EER facilities for an Onshore Plant shall consider the interactions with those parameters outside the physical boundaries of the facility, which could potentially impact on their design. Local geography, topography, surrounding land-usage, meteorological and oceanographic data (where appropriate), etc., should form the basis of these considerations. Historical adverse weather conditions and natural events, such as: landslides, ice, flooding, electrical storms, earthquakes, etc, which could negatively impact the EER philosophy, should be understood at the conceptual stage and contingency plans produced where appropriate.

8.1.1

Plant Layout At its incipient stage, the design of an Onshore Plant will begin with its layout and it will be beneficial at this time to be mindful of the appropriate hazards associated with the plant and arrange the layout accordingly by identifying hazardous and non-hazardous processes and placing them in segregated areas.

Access and egress routes for personnel should also be incorporated at an early stage of design - for guidance on the design of access and egress routes see sections 8.1.2 and 8.2.2 below. The layout should facilitate ease of access by Emergency Response Teams and Emergency Response vehicles, where appropriate, including external firefighting or Rescue units. 8.1.2

Manning Levels, Distribution and Control Systems Manning levels at an Onshore Plant can be assumed to fluctuate on a day-today basis. However, more noticeable fluctuations will exist depending on the stage of the plant life cycle, i.e. construction, operation, maintenance, etc. However, a maximum number of allowable personnel on the site should be set and the EER facilities designed for this maximum. This entails that all fixed EER facilities, such as: the number and size of exits, Escape/Evacuation Routes, etc, i.e. those which are not easily altered following construction, should consider the entire manning life-cycle as its basis of design. An accurate account of the manning levels and personnel distribution across the plant at any one time is essential information for coordinating emergency actions during a hazardous event. Therefore, a system should be put in place, which will be active throughout the manning life cycle of the plant, which effectively controls these factors and enables this information to be readily available to those controlling emergency activities. Internal communications are also a vital contingent of this control – for further details refer to section 8.4.1.

8.2

Escape Facilities shall be provided which enable personnel to Escape safely during a hazardous event from all accessible areas on the plant. These facilities should be capable of surviving a predetermined hazardous event appropriate to their location and also provide redundancy in case of system failure. The plant specific EERA will define the Escape and Evacuation time for that site and shall be based on the most onerous, probable hazardous-event, such that Escape relies on the availability of the redundancy of the Escape Routes provided. Escape and Evacuation time can be broken-down in to those periods required for: alerting personnel; to physically move to a place of relative safety, and; for personnel to muster and a roll-call to be taken.

Escape and Evacuation time shall be used to define the survivability of the Escape systems, that being, the duration required to affect the safe Evacuation of all personnel, which will subsequently identify the level of protection required to achieve this survivability. 8.2.1

Alerting Personnel Alerting personnel should be by audible means, usually via the Public Address and General Alarm (PAGA) system, and visual means (beacons) in areas of high ambient noise. A suitable alarm appropriate to the hazard should be delivered to those personnel in affected areas and a plant wide address for those considered as being not immediately affected. All alarm trip signals, either from automatic detection devices or Manually Activated Call-points (MAC), shall be sent to the Central Control Room (CCR) where the appropriate level of public address and emergency action will be conducted. Personnel should be made aware of the different alarm signals and their appropriate response to them during their training and plant orientation. The PAGA system shall be suitable for use in hazardous areas, where applicable, and be capable of surviving a predetermined hazardous event appropriate to their location and also provide redundancy in case of system failure.

8.2.2

Escape Routes Escape Routes shall be provided to the requirements defined below, in order to facilitate the egress of personnel from any area affected by a hazardous incident or as directed by PAGA (see section 8.2.1 above). Those hazards which could potentially result in the impairment of Escape Routes shall be identified during the project FERA, typically, impairment comes as a result of jet fire impingement or high radiant heat levels at the Escape Routes. The impairment criteria for radiant heat levels shall consider the applicable codes, standards and regulations in Section 5.0 with respect to the maximum allowable incident heat flux a target - be it personnel or equipment/structure – can sustain before the impairment of its function.

The survivability of Escape ways shall consider the findings of the FERA and EERA and shall be used to define their level of required protection, where appropriate, with the use of active cooling and/or passive heat shielding. Their availability shall be protected by means of redundancy below. Number and Size It is generally acceptable to provide a minimum of 2 Escape Routes from any area, which is accessible by personnel; dead-end corridors greater than 7 m should be provided with two means of Escape/exits. The size of Escape Routes shall be appropriate to allow for the safe unobstructed passage of the number of personnel as appropriate to the areas through which they pass and as defined in section 8.2.1. Access routes should also be sized considering the size of portable appliances which may be expected to travel along them. Lighting, Signage Additional reference should be made to Document No TO-HQ-02-074 Philosophy for Safety Equipment Onshore. All Escape Routes shall be sufficiently illuminated and provided with emergency lighting to levels required by the local regulations (see Document No TO-HQ-02-018 - Philosophy for Lighting and Trace Heating Onshore). Appropriate signage and/or luminous floor markings showing the direction of travel to be taken in order to reach a place of relative safety should be placed in prominent positions and locations along every Escape Route, particularly at locations at which the path changes direction or level. Signage should also be provided indicating firefighting equipment or life saving equipment with reference made to Document No TO-HQ-02-074 - Philosophy for Safety Equipment Onshore. Muster Areas Muster Areas should be provided where personnel may be required to temporarily muster prior to Evacuation. Typically, the size of the Muster Area(s) should be equivalent to ~0.5m2/person.

8.3

Evacuation The provision of Evacuation systems is generally considered redundant for Onshore Plants, in which the Escape facilities are usually considered to be sufficient to affect the safe removal of personnel from a hazardous event.

8.4

Rescue Rescue operations involve the following: •

Recovery of personnel

•

Onsite medical assistance

•

Emergency Evacuation of seriously injured persons

Procedures shall be established during design for Rescue operations employing the use of onsite fire brigades/firefighting teams or local authority fire services should also be considered with respect to local authority requirements and OMV’s own philosophies. 8.4.1

Telecommunications Communication systems shall be provided to allow personnel on the installation to effectively execute their emergency duties and communicate with the CCR during normal and emergency operations.

8.4.2

Recovery of Personnel Onshore, the recovery of personnel is generally restricted to those who are injured and who cannot affect their own Escape.

8.4.3

Onsite Medical Facilities Onsite medical facilities are site specific and shall be in accordance with the applicable codes, standards and regulations detailed in Section 5.0 and are to be defined during the plant detailed design.
