shall rely o n local manual operation. They are described
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
emissions.
b. Reduce as far as possible the num ber o f con fined areas.
c. Consider the effects of vent i la t ing or b lanket ing

ignition.

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

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

both these tasks be entrusted to the Approved Manufacturer,
or that the Manufacturer s instructions are followed implicitly.
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.

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.

All forms of automatic detection shall cause an audible

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

The duty fire pump shall normally be started by a signal from
the main fire and gas panel upon loss of ring main pressure
beyond the capacity of the jockey pump to recover.
Dedicated signals shall be provided for duty and standby sets,
but should a duty pump running signal ot be received back
within thirty seconds, then the standby set shall be called
upon in any case. The starting arrangements and sequence

directly affected by any failure and means that if an
incident also arises, then emergency operations will be
disrupted far less. Valve-operating handles and
