1 HSE DIRECTIVE 11 SAFE JOB ANALYSIS Directive owner per Bjarte Skulstad Please consult the asset s HSE instructions for potential installation specific requirements SJA

2 1 GENERAL Purpose The purpose of the directive is to ensure that a Safe Job Analysis is used when planning critical work tasks a Safe Job Analysis is carried out in a systematic manner and in accordance with standard practice on the Norwegian continental shelf Domain The directive applies to all BP-operated and contracted installations on the Norwegian continental shelf Onshore facilities or projects where BP Norge have a particular responsibility and which are assessed being part of the petroleum activities. Contractors of contracted installations who have a system that satisfies the requirements in this directive, may use their own system provided this has been clarified upon implementation References Activities regulations 30 OMS Risk 3.1 Risk Assessment and Management Norwegian Oil and Gas Association guideline 090 Common Model for Safe Job Analysis HSE Directive no. 1 - Work Permits Definitions and abbreviations A Work Permit (WP) is a written permission to carry out a defined job at a specific place on an installation in a safe manner and under certain conditions The Department Manager is the manager of a specific department CCR (Central Control Room) HSE function (safety officer) - HSE advisor The Area Authority is head of all activities within a certain area The Area Technician has the operational responsibility for a specific system or area The Offshore Installation Manager (OIM) is the top manager of all activities in the field A Safe Job Analysis (SJA) is a systematic and step-by-step review of all elements of risk carried out prior to a specific task or operatoin so that measures can be taken to remove or control any elements of risk identified during the preparation for or performance of the said task or operation. The person responsible for the SJA is the person responsible for the SJA, e.g. the supervisor, area authority or anyone else given the responsibility for the work to be performed. A CCR Technician is a person in the central control room who controls and coordinates all production and other work on board. 317

3 2 RESPONSIBILITY Offshore Installation Manager (OIM) is responsible for ensuring that a Safe Job Analysis (SJA) is carried out for critical operations as described in the directive ensuring that SJAs are performed in accordance with the directive and guidelines ensuring that all relevant personnel have the knowledge necessary to prepare a SJA, in line with their roles in connection with the performance of SJAs Person responsible for the SJA is responsible for preparing and inviting to the SJA meeting chairing the SJA meeting ensuring that analyses with participants are documented ensuring that all identified measures are implemented ensuring that experiences are summed up on completion of the work Person responsible for performing the work (Supervisor) is responsible for performing the work concerned ensuring that conditions and measures identified in the SJA are satisfied and implemented Person responsible for measures is responsible for carrying out measures identified in the SJA Department Manager is responsible for filing all completed SJAs in his/her department Area Authority is responsible for approving the SJA 3 USE OF SAFE JOBANALYSES Identifying the need for a SJA A Safe Job Analysis (SJA) shall be carried out for a work task when oorisk elements exist or may occur, and these are not sufficiently considered and examined in procedures or work permits oothere is a requirement for this in procedures, directives or work programmes 318

4 The following must be taken into account when considering the need for a SJA : 1. Is the work task described in procedures/routines or does it require deviations from these? 2. Have all the elements of risk been considered and examined through the work permit? 3. Do undesired incidents often occur in this type of work? 4. Is the work risky, complex or does it involve more than one discipline group? 5. Is new equipment or methods not covered by procedures or methods used? 6. Do the personnel performing the job have experience in the work concerned? Responsibility for identifying the need for a SJA Everyone involved in planning, approving and performing work and work permits shall consider whether a SJA is required A new SJA shall be carried out for each job. It may nevertheless be sensible to use lessons learnt from previously performed SJAs When the need for a SJA has been demonstrated, a person responsible for the SJA shall be appointed 4 PERFORMING SJA`S Preparation in preparation for an SJA meeting, the person responsible for the SJA shall collect data, drawings, previous experience and any available risk assessments for the work in question prepare draft breakdown of the work into sub-tasks and showing sequence of the work execution consider preconditions for the work define participants to carry out the SJA (the SJA group) call an SJA meeting the SJA meeting must be carried out as near in time as practically possible to the start-up of the work Participants in the SJA group Everyone actively involved in the preparations for and performance of the job concerned will normally be part of the SJA group, and may include: The person responsible for the SJA The supervisor The area authority The area technician The performing personnel The relevant safety delegate (shall always be invited) 319

5 Personnel with relevant discipline skills for the analysis Personnel affected by the work HSE function Performing a SJA The SJA Form shall be used for implementation. The Guidelines for using and filling in SJA forms can be used. 1. The person responsible for the SJA reviews the job to be done, with preconditions and necessary basis for planning 2. The SJA group shall carry out an inspection of the work site 3. The SJA group breaks down the entire job into sub-tasks, which are described briefly, clearly and action-oriented 4. The SJA group identifies potential hazard elements for personnel, the environment or financial values for each sub-task 5. The SJA group considers the probability of hazard elements, and consequences in the event that hazards arise, on the basis of their experience and best judgement. A risk matrix can be used to facilitate this process 6. The SJA group identifies primarily measures that can prevent hazardous incidents from occurring (probability-reducing measures). The SJA checklist is to be used to quality-assure that potential hazard elements, consequences and measures are assessed 7. The person responsible for the SJA identifies persons responsible for the identified measures, and notes this information on the form 8. The SJA group evaluates remaining risk and conducts a comprehensive evaluation to determine whether the work can be/cannot be implemented Documentation The Safe Job Analysis must be documented in the SJA form which will be signed by the person responsible for the SJA on behalf of the SJA group The SJA checklist and signed List of Participants must be attached to the SJA form Approval The area authority and supervisor review and approve the SJA form The daily information meeting will be informed of, and coordinate the planned SJA job Performing a job All personnel involved will go through the job immediately before starting to work. The job must be performed in accordance with the SJA and the work permit 320

6 Prior to and during the work being performed, the supervisor shall ensure that oothe preconditions for the work are fulfilled ooall planned measures have been taken The work must be stopped forthwith in the event of changes in the preconditions or measures described in the SJA and may not be resumed until a new SJA has been carried out. The supervisor must make sure that any new performing personnel go through the SJA documentation thoroughly before starting to work. This must be documented and signed for on the List of Participants Experience transfer On completion of the work the person responsible for the SJA will prepare a brief summary of the SJA-related lessons learnt from the work. The summary will be registered in the SJA form The department manager will file the SJA form w/appendices and the lessons learnt for his/her department. The SJA must be numbered so as to be easily retrievable 321

14 ATTACHMENT 5: RISK MATRIX Assessment of hazards probability and consequence In some cases it may be appropriate for the SJA group to use a risk matrix in the assessment of a hazard, i.e. assessing the probability of an undesirable incident occurring, and its consequences. A risk evaluation of this kind may help clarify the need and priority of measures to reduce the risk or its consequences. The evaluation method is a rough qualitative approach, and highrisk hazards may well be subjected to a more detailed evaluation later on. Using the risk matrix A risk matrix is used to assess/estimate risk by plotting the probability of an undesirable incident along one axis and the degree of consequences along the other axis. This must be done for each subtask, cf. the SJA form. If the combination of probability and consequence (cf. the matrix) reaches Medium or High, measures will be needed. Each company will generally have their own matrix used in risk analysis, but a simplified version such as the one shown below with three levels of probability and three degrees of severity, may be useful when performing SJA. Probability Consequence Low Medium High Low L L M Medium L M H High M H H Degree of consequence/severity High Death, serious injury or illness, significant contamination, significant damage to equipment or materials, significantly delayed production, gas-/oil leak, impairment of all or parts of the facility s safety integrity Medium Day Away From Work Case minor injury, minor pollution, minor damage to equipment/material, minor deferred production, minor gas-/oil leak, weakening parts of the facility s safety integrity (for example, a module) 329

15 Low No personal injury, small/negligible pollution, small/ negligible damage to equipment or materials, insignificant deferred production, negligible gas-/ oil leak, local/negligible deterioration of the facility s safety integrity Probability: High Probably, may happen several times during a year Medium Possible, may happen occasionally, the incident has occurred on the installation Low Not very realistic/likely, but conceivable, the event has occurred in the industry 330
