This Directive provides the minimum requirements for companies and establishments

that are subject to the supervision of the High Commission for Industrial Security

(HCIS), Ministry of Interior, for all plant buildings, including but not limited to buildings

that contain control rooms, process instrumentation buildings, communications buildings,

electrical substations, operations and maintenance office buildings, maintenance shops,

storages buildings, and mosques.

1.2 Application

This Directive is applicable to all facilities, including new projects, the expansion

of

existing facilities, and upgrades. For application to existing facilities, the Owner shall

assess his facilities against the requirements of these Directives and coordinate with the

General Secretariat of the HCIS to comply with the security, safety, and fire protection

requirements according to these Directives and add to or

modifY

the existing facilities

as

required. Where the General Secretariat of the HCIS has assessed deficiencies

in

existing

facilities during a survey, comparing the current state

of

the facilities to the requirements

of

these Directives, those identified deficiencies shall be corrected by the Owner.

1.3 Conflicts and Deviations

Where implementation

of

a requirement is unsuitable or impractical, where other

equivalent company or industry Standards and Codes are followed, or where any conflict

exists between this Directive and other company standards and Codes, the deviations

shall be resolved by the General Secretariat of the HCIS. Deviations lower than the

requirements of this Directive shall be listed and submitted

in

a report of non-compliance,

with justification and rationale for not following the requirement, and approval shall be

received from the General Secretariat

of

the HCIS prior to implementation. The

documents shall be retained by the company

in

its permanent engineering files.

Control Buildings

and Other

Buildings Requiring Blast Resistance

5.1 Control buildings, multiple-occupancy buildings that contain control rooms, and other

functionally significant buildings that are identified by the Owner to require equivalent

protection

in

refineries, petrochemical plants, and other types

of

facilities that produce,

process, or store flammable, toxic, or explosive substances,

shaH

be located to minimize

exposure to fire, explosion or release of hazardous materials (see Section 4.1, above).

When necessary, they shaH be made blast resistant to the extent needed to prevent

coHapse due to overpressure from a vapor cloud explosion if one were to occur from a

plant-related incident.

5.2 While the spacing and design of the control building should be guided by the principles

of API 752, the minimum spacing between a control building (or building that contains a

control room) and vessels, tanks, or other process equipment handling combustible,

flammable, toxic, or explosive materials

shaH

be 30 meters.

5.3 The control building shall be designed to prevent the entry of combustible, flammable, or

toxic liquids, gases or vapors.

5.4 Control buildings located inside

of

a plant

shaH be

single-story and without windows.

Exceptions: In plants where there

is

no explosion hazard, 5.4 does not apply or where the

Owner s engineer otherwise approves multi-story construction. Where the windows are

speciaHy designed to withstand the overpressure should an explosion occur, windows are

aHowed.

5.5 Control buildings shall be blast resistant to the extent needed to prevent collapse from a

plant-related incident. Design of blast resistant buildings shall be accomplished by a

registered or chartered professional engineer that is experienced

in

blast resistant

structural design. Simulation

of

the resultant overpressure and suction overpressure from

a potential plant related explosion shall be done using a registered or chartered

professional engineer from an engineering firm that specializes in such simulation. The

results shaH be used for the basis of structural design by a professional engineering firm.

5.5.1 The simulation shall be used to select blast overpressure and duration (impulse) for the

structural design basis.

5.5.2 The simulation shall take into account existing process equipment and future plant

expansion equipment that is likely to be installed.
