Rev. 1 Permit to Work System Awareness Plus Presentation Covers the General Work Permit’s Use With Other Permit Form

Rev. 1 2 OBJECTIVE  To explain the work permit process and the various forms that may be used, and which type of form to use where.  To describe the basic requirements of a good permit system.  To understand in which situations a General Work permit is required.  To provide details on where additional information can be obtained.

Rev. 1 3 Work Permit The work permit process is done at the end of the assessment (planning) phase and is the beginning of the control phase of the hazard management process.

Rev. 1 4 Types of Work Being Permitted  GENERAL (Cold) WORK : Covers all maintenance and construction activities, or any other activities outside normal operations that does not involve any form of hot work or confined space entry.  HOT WORK: Covers all work activities that involve a source of ignition, or where sufficient heat may be generated to ignite flammable or combustible materials. Used in conjunction with a General Work Permit  CONFINED SPACE ENTRY: Required for entry into any area, storage vessel, with restricted entry and exit and where there is a potential for a hazardous environment to exist.

Rev. 1 5 Type of Work Versus Type of Permit Form Required  General (Cold) Work General Work Permit or an equivalent permit form  Hot Work Hot Work Form or an equivalent permit form  Confined Space Entry ---- Confined Space Entry Form or an equivalent permit form  Other Forms that may be required in conjunction with the relevant work permit, but are themselves not a work permit:  Energized Electrical Work Form  Excavation Form  Equipment Isolation Checklist  Job Safety Analysis (JSA) form

Rev. 1 8 Energized Electrical Work Form The Energized Electrical Work Form’s Section ”B” can be used to help ensure energized electrical equipment is properly prepared for work. Section “A” Section “B” of this form is to be completed by a qualified electrician who is to perform the work. Section “C” to be the approval section to be completed by the facility’s management or their delegated personnel.

Rev. 1 9 Equipment Isolation Checklist

Rev Phases of the Work Cycle  Planning Phase -- Before any work can begin ●Plan the work ●Review the job site ●Complete Lock-out & Tag-out of equipment as per the completed Equipment Isolation Checklist ●Review job tasks with facility management/operations ●Initiate the necessary work permit forms ●Explain the permit conditions and requirements to the Permit Holder ●Permit Holder to conduct a tool box talk with the workers and post at the job site.  Work in Progress Phase ---- During the Work ● Workers to comply with all permit and Job Safety Analysis conditions and requirements ● Stop work if job’s scope or site conditions change ● Monitor personnel during work  Completion of Work Phase ---- Permitted work completed ●Permit Issuer (or designated person) to inspect job site before closing

Rev Permitting Sequence  All permitted work requires a General Work Permit to be issued for the job task required to be issued.  Normally the General Work Permit will be valid for the entire shift of the Permit Issuer.  If hot work is required to be performed an additional Hot Work Form must be issued in addition to the General Work Permit.  Normally the Hot Work Form will be issued for the period the hot work is required and not for the entire shift.  If confined space entry is required a Confined Space Entry Form shall be issued in addition to the General Work Permit.  If work on energized electrical equipment is required an Energized Electrical Work Form shall be issued in addition to the General Work Permit.

Rev Permits Extension and Renewals  Permit extension (Same Day) All three of the Work Permitting forms can be extended, but the total time of the work permit can not exceed 16 hours.  An extension can only be granted by that shifts Permit Issuer with all copies being recovered and signed by the Permit Holder and Permit Issuer.  Renewal Work Permits for General Work and Hot Work can both be renewed for up to six days providing there is no change to the scope of work, site conditions and all requirements of the permit are verified as continuing to be met. Note: A work permit for entry into a confined space can not be renewed, a new permit must be completed each day.

Rev Work Permitry Forms - Minimum Requirements  Permit forms shall at the minimum include the following elements:  Permit forms to have an original and either one or two carbon copies.  Permit form’s original to be in the language of the land, and (if not English) one carbon copy to be in English and the second in the language of the land.  Permit forms to be printed with sequential serial numbers  Different types of permits/forms are to be identifiable by their color. (e.g. Yellow – General Work Permit, pink – Hot Work Form and Green – Confined Space Entry Form, Energized Electrical Wok Form - Blue)  Permit Issuer to go over all permit requirements and conditions with the Permit Holder who will then sign the form if in agreement.

Rev Work Permitry Forms - Minimum Requirements (continued)  Original (and if not in English an English copy) to be issued to the Permit Holder.  Permit Holder to conduct a Safety Briefing with workers.  If Permit Holder will work alone he is required to complete a “Safe Performance Self Assessment” before starting work.  Permit Original shall be displayed in a visible location at job site.  Originals( and copies) to be returned to the permit issuer upon completion of the work or end of permit form’s allotted time frame.  Permit Issuer to confirm job completed and job site OK before the permit form to be signed off as completed.  Work permits to be retained for a defined period as define by Company and or Regulatory requirements.

Rev Work Permits Forms -Contents  Each work permitry form shall clearly cover the following:  A specific description of the work to be done.  The location of the work site and or area.  The identification of the equipment to be worked on.  The name of the person requesting the permit.  The date and times for which the permit is valid.  A list of the tools required to perform the work.  Cross reference to other permit forms or other documents  What product the vessel or equipment last contained.  Details of any gas testing conducted (as appropriate).  Details of isolation requirements (Lock-Out & Tag-Out).  Details of any special safety precautions and site conditions required.  An Approval & Sign Off Section

Rev Work Permit – Requirements Before Starting Work After issuance of a Work Permit the following must occur before work commences:  All conditions, precautions, and restrictions on the permit must have been satisfied.  Any additional forms noted as being required must be obtained (e.g. Confined Space Entry Form, Hot Work Form excavation form, Energized Electrical Work Form)  Permit Holder to hold a safety briefing at job site to convey the permit or permits requirements and conditions to the workers at the work site.  Permit and copy of related forms (JSA, EIC) is to be suitably displayed at the work site.  Work must commence within 30 minutes of the permit being issued or if not, revaluated by the Permit Issuer.
