HSE POLICY, OBJECTIVES OF THE PTW SYSTEM AND ITS CUSTODIANSHIP

CHAPTER 1

HSE POLICY, POLICY, OBJECTIVES OF THE PTW SYSTEM AND CUSTODIANSHIP 1.1 GASCO HSE POLICY The GASCO HSE Policy includes the statement that ‘GASCO shall conduct activities in a manner designed to minimise HSE risk to a level which is As Low As Reasonably Practicable (ALARP)’. Amongst its activities, GASCO requires to carry out work, which may be in Operational or Non-Operational Areas of Plant facilities or Pipelines. In order to manage the potential risks associated with this activity to ALARP, GASCO has developed a Management System of Control, called the “GASCO Permit to Work (PTW) System”. The GASCO Permit to Work System is described in this Manual. 1.2 LEGAL REQUIREMENTS The United Arab Emirates Law No. 8, for year 1980, on Conservation of Petroleum Resources Chapter V, Articles 91 & 92, and Ministerial Order No. 32 for year 1982, Protection of Employees Against Occupational Hazards Article-1, state that: “Every employer shall provide adequate preventative equipment to protect workers against the dangers of employment accidents and occupational diseases that may occur during the work and also against fire hazards that may result from the use of machines and other equipment. He shall also adopt all other preventative methods ordered by the Ministry of Labour and Social Affairs.” “Every worker shall use the protective equipment and the clothing supplied to him for this purpose, shall comply with all the instructions given by the employer to protect him against hazards and shall not take any action liable to hamper compliance with such instructions.” “Every employer shall display detailed instructions in a conspicuous position at the work place indicating the measures to be taken to prevent fire and protect the workers against the hazards to which they may be exposed while performing their work.” The GASCO PTW system is a key part of the measures implemented by GASCO to comply with these legal requirements.


CHAPTER 1

Page 2 of 7

1.3 OBJECTIVE OF THE PERMIT PERMIT TO TO WORK SYSTEM SYSTEM

The prime objective of the GASCO PTW system is to ensure that potentially hazardous work is properly controlled and co-ordinated. It is the means of providing written instructions and authorisation to people carrying out such work. It is a key part of the measures taken to safeguard people doing the work, others who may be affected by the work, and the facilities themselves. It uses documents to define the work, the associated hazards and the precautions to be taken for those hazards, and includes a system of authorised signatories for the preparation of the documents. It defines the roles and responsibilities of persons in the GASCO Organisation, and those of Contractor management, with respect to the GASCO PTW System.


CHAPTER 1

Page 3 of 7

1.4 PURPOSE AND SCOPE

The purpose of the GASCO PTW System is to ensure that a safe working environment is achieved by providing management control over the various work activities, which may be potentially hazardous. The PTW System provides a formal and controlled process that identifies and communicates hazards and risks associated with planned work and ensures that appropriate precautions and control measures are implemented so that the work can proceed and be completed safely. It is important to note that a Permit to Work is not a permission to carry out hazardous work. It is an essential part of a procedure that provides instructions on how to carry out any potentially hazardous work safely and in a managed, controlled way. The PTW System has the following key features:

•

It allows personnel to be aware of the potentially hazardous activities being undertaken under PTW by providing a systematic overview. The specific arrangement for the display of Permits allows identification of potentially conflicting work tasks, both on a geographical and time basis;

•

It defines the controls required to prevent threats from releasing hazards during the work as well, as the recovery controls that will mitigate the effects should a hazard be released;

•

It sets limits to the duration and extent of the work;

•

It encourages formal and careful attention to safe systems of working by requiring the signature of specified individuals, who must confirm satisfactory completion of the various stages of the Permit lifecycle, viz: o

Hazard Assessment and Risk Assessment

o

Precautions and Controls

o

Worksite Preparations

o

Handover and Handback


CHAPTER 1

Page 4 of 7

1.5 CUSTODIANSHIP OF THE PTW SYSTEM

The GASCO PTW System requires that appropriate ‘Custodians’ within the GASCO Organisation undertake responsibility for the PTW System. The Principle Custodian, responsible for authorising all changes to the GASCO PTW System, is the Senior Vice-President Operations, (SVP (O)). The Custodian responsible for the development of the PTW System and the co-ordination across GASCO is the GASCO HSE Vice-President (HSE). Custodians responsible for the implementation of the PTW System are the Plant and Pipeline Vice-Presidents (the Asset Owners).


CHAPTER 1

Page 5 of 7

1.6 DEVIATIONS FROM THE PTW SYSTEM

Deviation from the PTW System may be necessary in special circumstances, but the safety of personnel, the protection of the environment and assets must not be jeopardised. Once the situation is normalised, the PTW System must be re-applied. If anybody involved in the PTW System is unsure of a course of action, he must consult a higher authority and not take risks. Any planned deviations from the procedures contained in this document must be requested by the Plant or Pipeline Vice-President, in writing, to the Senior Vice-President Operations (SVP (O)). Approved derogations will be issued as a Supplementary PTW procedure, authorised by SVP (O) and approved for issue by the Plant or Pipeline Division Manager for subsequent inclusion in Chapter 10 of the PTW System Manual. The PTW Supplementary procedure will normally only apply to the location that has requested derogation from the procedure. The Supplementary PTW procedure will inculde a description of the deviation and the expiry and is to be issued, by the Plant or Pipeline Division Manager, to all registered holders of the PTW System Manual at that location. During the validity period of the authorised derogation, the PTW Suppliementary procedure is to be filed in the Deviation Chapter of the PTW System Manual by each respective manual holder. The required validity period of any PTW Supplementary procedure is to be agreed with SVP (O). Upon reaching the expiry date, unless further approval is obtained in writing from the SVP (O) for an extension to the original expiry date, the PTW Supplementary procedure is to be rescinded and copies removed by the registered holder of each controlled copy of the PTW System Procedures Manual at that location.


CHAPTER 1

Page 6 of 7

1.7 CONTROL OF PTW SYSTEM MANUAL

Only controlled copies of the PTW System Manual are to be used. The latest revision of the PTW System Manual will be available on the GASCO Intranet for all staff. To ensure that the PTW Manuals in circulation are current the following document management procedure is to be complied with:

•

Hard copies of the PTW Manual will be circulated to registered holders only. Each copy of the PTW Manual will have a unique number and will be registered as a controlled copy. No uncontrolled copies of Manuals, or sections of Manuals, should be made;

The PTW Manual is designed in Sections to allow easy revision and update without the need for reissue of the complete manual. Each section will have a revision number and effective issue date; Only the register holders of the PTW Procedures Manual will be issued with updates; A transmittal note will accompany original manuals, and subsequent revisions to manuals, to each holder of the controlled copy of the manual The holder of the controlled copy of the manual has the responsibility for:

•

Inserting revisions,

•

Removing and destroying superseded pages,

•

Updating the history page at the front of the controlled manual;

•

Completing the amendment record;

•

Completing the return section of the transmittal note to HSE/S;

•

Advising all his staff who are ‘users’ of the PTW System with regard to the changes.
