2. GENERAL SAFETY AND FIRE PROTECTION PHILOSOPHY The general safety and fire protection philosophy recognizes following main activities :

2.1.1



Safeguarding of personnel.



Safeguarding of plant.



Safeguarding of production regularity.



Safeguarding of the environment.

To accomplish these safeguarding activities two steps will be followed :  

Minimize loss of confinement, i.e. releases of flammables to the atmosphere. Minimize the consequences of a loss of confinement i.e. explosion, fire, toxic releases.

The minimization of the consequences of a loss of confinement (the main topic of this document) is achieved by the following main means : 





Providing a safe plant layout by separation of hazards (e.g. leak sources from ignition sources), building and drainage of liquid storage and spill risk areas, separation of hazard units to prevent escalation and by inclusion of adequate access and escape routes. Fire/gas detection and shutdown / blow down systems designed to isolate and render safe sections of the plant involved in a hazardous occurrence. Fire fighting systems designed to minimize the effects of fire either by fire extinguishing or exposure protection.

TRIPATRA – TOYO CONSORTIUM File: 46397892.doc

PS-1100-MEC-019 R1 Page 5 of  16

South Jambi “B” Shallow Gas Project 

Essentially a manual intervention policy will be followed for defining fire fighting system and equipment requirements. This means that site personnel will carry out most fire fighting tasks, using fixed and mobile appliances in conjunction with the fire main system. Fixed fire protection systems supplied from the fire main will be used where manual application is not adequate or may  be hazardous to the fire fighters. Independent fixed fire protection systems using gaseous agents will be used where they are the most effective and appropriate means of fire suppression, e.g. for  gas turbine enclosures. Safety and fire protection system provision and design will make use of codes and recommended  practices as the main basis.

3. FACILITY LAYOUT 3.1

Basic Principles

In designing the layout of the plant, including associated facilities, the Contractor shall consider  the following :

3.1.1



Efficiency / Operability



Safety

The principle of efficiency / operability ensures that : 

The process flow is arranged in a logical manner.



Equipment and controls are arranged to facilitate operation.



Ease of maintenance is provided.



Cost are minimized.

The following are the main aspects to be considered for a safe plant layout : 

Limited inventory in a process area.



Access / escape for fire fighting.



Separate ignition sources from likely leak sources.



Limit fire water requirements.



Limit fire spread caused by hazards escalating from one plant area to adjacent ones.

The safety criteria for initial plant layout are taken from Company requirements, from relevant codes and standards and from recommended good practice.

Detail Requirements

For the Gas Plant Facilities, the separation distances between equipment within process units and  between process units and other plant items / areas shall be based on the distances given in Appendix I. Flares shall be located to meet the radiation levels given in API RP 521 and at least 300 ft from  process, utility or offsite facilities.

Conditions

Heat intensity in structures and in areas where operators are not likely to be performing duties and where shelter from radiant heat is available (for example, behind equipment) Valves of K at design flare release at any location to which people have access (for example, at grade below the flare of a service platform of a nearby tower), exposure should be limited to a few seconds, sufficient for escape. Heat intensity in areas where emergency actions lasting up to 1 minute may be required by personnel without shielding but with appropriate clothing. Heat intensity in areas where emergency actions lasting several minutes may be required by personnel without shielding but with appropriate clothing. Value of K at any location where personnel with appropriate clothing may be continuously exposed.

The direction of the prevailing wind shall be considered in locating the control building, offices, workshops, etc. Escape and access ways will serve both personnel and fire teams (together with their equipment such as fire fighting vehicles and trailers). The minimum clearances to be provided in the design shall be in accordance with the following unless approved otherwise by the Company.

(see Appendix I) Piping Over roadways Beneath main pipe ways

7’ – 0” 3’ – 0”

16’ – 0” 12’ – 0”

There shall be two escape routes from rooms, platforms and confined work areas. However only a single escape route is required from small rooms, platforms or confined work areas i.e. where maximum distance to the point of escape (door) is 16 ft. Where frequently daily access to elevated equipment is required, stairways rather than ladders shall be provided. Where ladders are used they shall have non-slip rungs and safety bars at entry points. Ladders on tall structures (e.g. columns) shall have staggered intermediate platforms and safety cages shall extend to the handrails of these intermediate platforms.

4. FIRE PROTECTION SYSTEMS 4.1

General

The basic principle to be applied to the design of fire protection systems is manual intervention. Generally fire extinguishing and equipment protection will be manually applied. In those instances where manually applied fire fighting is not adequate then fixed / automatic systems shall be provided. The Fire and Gas Detection System is designed to give warning of hydrocarbon releases to the atmosphere and fires. Such warnings will initiate response by each facility fire team. General requirements for fire and gas detector location and the associated control system and logic are contained in the Project Specification for Instrumentation General Requirements, document number PS-1100-ICC-001. Fire detection systems shall be located in all administration/camp buildings not protected by automatic sprinklers. Smoke detectors shall be installed in all sleeping quarters. Fire alarms for the camps and offsite shall be transmitted to the fire alarm panel in the control room from sub alarm panels in the fire station and senior staff house building. TRIPATRA – TOYO CONSORTIUM File: 46397892.doc

PS-1100-MEC-019 R1 Page 8 of  16

South Jambi “B” Shallow Gas Project 

Fixed fire protection systems will be used where rapid (i.e. automatic) system operation is necessary to achieve the fire protection aim (a typical example being gas turbine protection). Passive fire protection will be provided to maintain the integrity of structures and vessel supports whose collapse could lead to unacceptable fire escalation or damage equipment critical to the operation of the plant.
