1.1 To define the minimum requirements and procedures to ensure the safety and health of   personnel who work in or in connection with confined spaces.

2.0 SCOPE

2.1 This technical procedure applies to all personnel entering, working in and exiting a Confined Space on all projects.

3.0 DOCUMENT CONTROL

3.1 This Procedure will be a properly to this project. It is a controlled document means a document that is registered and has its distribution controlled so that a holder has the correct issue of the document at all times. All amendments, revision, will be subject to CM review and approval.

4.0 DEFINITIONS, TERMS AND ABBREVIATIONS

4.1 Confined Space An area where there is a possibility of exposure to toxic or   flammable gases and/or a deficiency or excess of oxygen and which requires a  permit to work.

4.2 Entry: The action by which a person passes through an opening into a Confined Space.

4.3 Competent Person, Confined Spaces A person assessed for his knowledge and experience of working in confined spaces and entered on the  Register of  Competent Persons.

4.4 Competent Person, Gas Testing A person assessed for his knowledge and experience of working with gas detection apparatus (as the 3rd Party Certification).

4.5 Standby Man An individual who is stationed immediately outside the Confined Space, whose sole duty is to monitor the authorised entrants in the Confined Space. He is also required to assist in the execution of the emergency procedures.

4.6 Hazardous Atmosphere An atmosphere that may expose employees to the risk of  death, incapacitation, impairment of ability to self-rescue (i.e. to leave unaided), injury, or  acute illness.

5.0 RESPONSIBILITY

5.1 The Project Manager has overall responsibility for the implementation of this technical  procedure.

Initially inspecting the area to ensure all hazards or potential hazards have been identified and controlled.

Testing the Confined Space for atmospheric hazards and documenting the test results on the work permit.

Verifying that the Confined Space has been isolated by locking and tagging out all energy sources leading into or out of the Confined Space.

Issuing the work permit.

Ensuring that all employees and subcontractors are familiar with this procedure. Arranging training for personnel who work in or supervise a Confined Space. Periodically monitoring work conditions in the Confined Space.

5.3 The Section Supervisor is responsible for the following: Ensuring that the workforce is working to this procedure.

Checking that the workforce is carrying out work method safely.

Ensuring that all tests have been properly conducted and that procedures and equipment are in place before endorsing the work permit and allowing entry. Planning the work, as far as practicable, to include contingency plans and emergency arrangements.

7.0 PROCEDURE

7.1 General

7.1.1 All work in a Confined Space shall be controlled by a Permit to Work Confined  S  pace Entry.

7.1.2 Prior to work commencing in the Confined Space, tests shall be carried out to determine whether there is a hazardous atmosphere present that could endanger the workforce carrying out the task.

7.1.3 The Competent Person, Gas Testing shall determine the composition of the atmosphere and record the results on the form Vapour and Exposure Test Report . All deficiencies must be corrected before entries can be authorised.

7.1.4 No personnel shall enter a Confined Space without being made aware of the contents of  the work permit and the conditions attached to it. A copy of the work permit must be  positioned adjacent to the entry to the Confined Space.

7.1.5 All hinged or swinging access hatches, doors and covers shall be substantially blocked, tied or otherwise affixed in the open position until the Confined Space is secured.

7.1.6 Guardrails, barricades or similar protection shall be provided around the Confined Space access points to prevent persons from falling into openings or making unauthorised entries.

7.1.7 Substances that are flammable and/or toxic shall not be used in a Confined Space without appropriate personal protective equipment and respiratory protection and the approval of the Site HSE Advisor.

7.1.8 Hoses supplying hazardous gases to areas within a Confined Space shall be equipped with “excess flow” check valve devices and shall not contain patches or repairs within the Confined Space or in the vicinity.

7.1.9 Dust generated within a Confined Space shall be controlled. Open flame work shall  be prohibited whenever a flammable atmosphere is present within a confined space.

7.1.10 The following equipment shall be available for use in a Confined Space. Employees will also  be trained in their proper use. The equipment includes but is not limited to:

Testing and monitoring equipment. Ventilating equipment. Communication equipment (i.e. lifelines).

Personal protective equipment.

7.4.4 The Section Supervisor shall terminate and cancel the entry and return the permit to work when one of the following conditions applies:

The work operations are complete.

When a condition that is not allowed under the work permit exists. A change in the use or configuration of a Confined Space.

7.5 Planning the Entry

7.5.1 The Section Supervisor will establish the need for a Confined Space work permit based on the job and conditions in the work area.

7.5.2 Ventilating the Space

7.5.2.1 The atmosphere of the Confined Space shall be purged of all toxins or combustibles. Ventilation shall be provided in order to ensure that the atmosphere is safe. The exhaust of the ventilating equipment shall be designed to protect workers from contamination of  the atmosphere. If the Confined Space is being ventilated prior to atmospheric

sampling, a rule of thumb is to ventilate long enough to have seven complete volume changes in the space.

7.5.2.2 When setting up the ventilation system, consideration should be given to the location of  fans order to provide the best airflow through the Confined Space.

 Not e_{: The air exhaust port shall be placed far enough away from the entrance in}

order to prevent re-circulation of this air back into the Confined Space.

8.0 RECORDS

8.1 The forms Confined Space Entry Log shall be attached to the  Permit to Work  Confined Space Entry to which they refer.

8.2 The work permit shall be the prime record and the document set shall be managed.

8.3 Documents generated by referenced procedures shall be managed in accordance with the originating procedure.
