in section 4.5 hereinafter.

4.1 .2 Explosion Hazards

The igni tion of m ixtures of combust ib le gas and a ir can lead to

explosions particu lar ly w here the mixture o ccurs in a conf ined

area.

The explosion protect ion phi losophy is to:

a. Reduce wh ere possible the occurren ce o f gas

e. Plan the layout of the Facility to minimize the effects of

any explosion which may still occur.

4.1.3 Toxic Hazard

Specification

umber

01

~ Y H I O O ~

The incoming hydrocarbons may contain up to 500 ppm of

hydrogen sulphide. Where this is the case, H,S concentration

within the gas handling parts of the process can reach

1200 ppm, typically in the crude tank vapours. Consequently,

all materials shall be selected strictly in accordance with the

Project drawings entitled Material Selection Guides.

Additionally, H,S detection sensors shall be installed around

the Facility and in inlets of HVAC systems to manned areas so

as to provide the earliest possible detection of leakage.

4.1.4 Pyrophoric Ignition

ev

1

As described in API RP 2001, steps shall be taken to prevent

the ignition of combustible vapours by the presence of

pyrophoric iron sulphide deposits. These deposits are found

in locations where hydrogen sulphide and other sulphur

compounds are formed in petroleum storage and petroleum

processes.

4.1.5 Accretions and Sludge

ate

5 8 94

a. As well as the combustible gases being present in the

atmosphere of a confined space, combustible and/or

toxic solid accretions and sludge may also be present.

Sheet

b. Provision must be made for their safe removal by

dissolving, flushing or by mechanical means.

4.1.6 Vehicle Impact

Vehicles entering the Facility present the possibility of vehicle

to vehicle, and vehicle to plant collisions.

This risk shall be

minimized by control of vehicle access, road layout, barriers,

driver training, and speed limitation inside the Facility.

4.1.7 Radioactive Materials

A limited amount of radioactive material will be introduced in

the form of smoke detectors. Normally, these will not present

a problem, but safe practices must be followed for their

maintenance and eventual disposal. It is recommended that

The use of radioactive material for non-destructive testing

(NDT) shall be controlled by operating procedures.

4.1.8 Lightning Strike

Lightning protection shall be provided in all buildings and

structures to minimise damage due to lightning strikes.

4 2

Princi~les f Facilitv Lavout

4.2.1 General

This section covers the main features which should be

considered when laying out the Facility. Careful

attention to equipment location can improve the safety,

accessibility and efficiency of the Facility.

Due consideration shall be given to the location of

process, utility, control and office areas, as well as

escape routes and safety equipment, having regard to

the relevant hazards.

The first approach to layout shall be to grade each

system according to the nature of the hazard and then

categorise the systems of similar grading as follows:

1. Systems which have the potential to emit

flammables.

2.

Systems which may emit toxic gases.

3

Systems which are a source of ignition.

4. Systems which must be located in an

unclassified area.

5.

Systems which are considered non-hazardous.

Typically, sources of flammables shall be segregated

from sources of ignition and control areas shall be

separated from all sources of flammable and toxic

emissions.

4.2.2 Control Room

a. A pressurised control room shall be located in a control

building so as to have a commanding view of the

Facility. The control building location shall be towards

one edge of the Facility so that it is not surrounded by

process or storage areas, and can be approached by

road without passing through the Facility.

b. Wherever possible the location shall take account of

prevailing winds to ensure that any gas leakage is not

blown towards the control building.

c. The building shall not be more than two storeys high

and shall be positioned at a minimum distance of 60 m

from the nearest process or storage area. This distance

shall not be reduced by any future process or building

expansion.

d.

All windows in the control room and other normally

manned rooms facing the direction of the Facility shall

be laminated glass having non-splinter characteristics.

Window frames shall be securely attached to the

building structure. Doors located on the process side of

the building should open outwards.

4.2.3 Roads

a.

The main access to the Site shall be via a controlled

access road to prevent unauthorised vehicles visiting

the site.

b. Roads on the Site shall be sized and laid out wi th due

consideration being given to the amount of traffic and

the requirements of emergency vehicles.

Hazardous Area Classification

4.3.1 General

a.

The objective of area class

fication shall be to avoid

ignition of

occur from

handling hy

releases of flammable vapours that may

time to time in the operation of facilities

fdrocarbons.

b. This approach is to reduce to an acceptable level the

probability of coincidence of a flammable atmosphere

and a source of ignition.

c. It is not the intent of area classification to guard against

the ignition of major releases of flammable materials

under catastrophic failure of plant which in properly

run facilities have a very low probability of occurrence.

d. Area classification is the assessed division of the

Facility into hazardous areas and non-hazardous areas

and the subdivision of the hazardous area into zones.

detector operation.

Automatic control actions shall only be initiated by

coincident operation of t wo or more detection inputs of

the same type from the same area.

Specification Num ber

01 5-YH-1003

Depending upon the area and type of detection this may

be audible alarm only, release of extinguishment or

shutdown initiation. Actions shall generally be as

defined on the Project drawings entitled Cause and

Effect Charts. These shall be developed by the

Contractor during detail design and submitted for

Company approval.

4 4 2 Gas Detection

ev

1

Gas at the Facility contains both heavier and lighter

than air components, at all stages of the process.

Heavier gases may include H2S,

lighter gases are

mostly hydrocarbons.

Due to the flat terrain, open layout of the Facility, and

prevailing winds, lighter gases are likely to move away

from any leakage fairly rapidly, mixing readily with air.

Heavier gases may settle in sheltered areas, between

equipment, in sumps, etc.

ate

5 8 94

Where the product includes a significant quantity of

H2S, any heavier-than-air gas cloud will contain both

H2S and hydrocarbons.

Sheet

11 of 26

H,S detectors shall therefore be provided in areas, as

described above, where heavier-than-air gases may

accumulate. In such areas, detection o f H2S will give

warning of toxic hazard, and also early indication of

presence of flammable hydrocarbon gas.

Where H2S s not present in a significant quantity, then

hydrocarbon gas detection shall be provided.

Point-type hydrocarbon detectors shall be installed at

locations where lighter-than-air hydrocarbon gases may

accumulate. On open Site areas, beam-type
