1 WORK AT HEIGHTS HSE DIRECTIVE 3 WORKING AT HEIGHTS Directive owner per Bjarte Skulstad Please consult the asset s HSE instructions for potential installation specific requirements

2 1 GENERAL Purpose The purpose of this directive is to ensure that all work at heights is carried out safely there are no accidents due to dropped objects all use of ladders takes place in a safe manner all scaffolding is erected, taken down and used safely work above the sea is carried out safely Domain This directive applies to all BP-operated installations and contracted installations on the Norwegian continental shelf. Contracted mobile installations which have a system that satisfies the requirements in this directive, may use their own system provided this has been clarified upon implementation. By following this directive, all requirements in the Working at Heights section in the BP 8 Golden Rules of Safety are complied with. Onshore facilities or projects where BP Norge have a particular responsibility and which are assessed being part of the petroleum activities References Regulations relating to scaffolding, ladders and work on roofs, etc. Regulation relating to use of work equipment The Norwegian Labour Inspection Authority s regulations OMS Procedure 4.5 Control of Work OMS Risk 3.2 Personal Safety Norwegian Oil and Gas Association guideline 088 Common model for work permits NS-EN 795 Protection against fall from heights. Anchoring methodes. HSE Directive no. 1 Work permits HSE Directive no. 11 Safe job analysis Use of Work Basket - ref. HSE Directive 4 Lifting Operations Norwegian Oil and Gas Association guideline Securing and rescue when working in heights (only in Norwegian) Norwegian Oil and Gas Guidelines 105 Scaffolding (including competence requirements) Norsk Standard NS , 2, 3, 4 Definitions and abbreviations Working at heights means all work carried out standing with one s feet two metres or more above deck level where there is no fixed platform or approved scaffolding Work permit is a written permit to carry out a defined work task at a given place onboard an installation under given conditions and in a safe manner Safe Job Analysis (SJA) is a systematic and step-bystep review of all elements of risk carried out prior to a 101

3 » specific task or operation 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 First line MOB (Man overboard) preparedness includes oothe platform s MOB crew standing by in case of an emergency or ooa standby vessel ready by the installation 2 WORKING AT HEIGHTS Competence for using fall arrest equipment Complete BP fall arrest course offshore (4 hour in house training for fall protection) or onshore basic fall protection safety courses For both courses the BP requiremet is 3 yearly verification/ repetition Use of safety devices all work carried out standing with one s feet 2 metres or more above the deck requires: oofixed platform with handrail, or ooscaffolding with green scafftag, or oouse of approved safety harness secured in a suitable anchor point which limits free fall to 2 metres from the footing, normally by use of a fall block, and oofilled in and signed Checklist for Work At Heights/Use of Harness. When moving at height outside a fixed platform, scaffolding or ladder an approved safety harness with fallblock (or, alternatively, a Y-line) shall be used. When relocating the fallblock, the person involved must be secured with a fall arrest line. When using fall arrest equipment ooat least one person shall be present in the area nearby at all times in order to alert and start basic rescue work in case of a fall ooif needed prepare a written Rescue Plan oothe rescue plan shall take the time for a safe rescue into consideration in order to be able to rescue a person within sufficient time (i.e. prevent blood circulation injuries). There shall be a site specific instruction on how required competent personnel are organized (for instance a rescue team) Securing underlaying area Tools and equipment shall, as far as practical, b e secured with suitable means to prevent them from being dropped If there is a potential for dropped objects the underlaying area shall be secured either with a guard person or roped off in co-ooperation with the area technician. 102

4 If dropped objects can damage pressurised equipment, the area shall be physically protected or de-pressurised in cooperation with the area techncian. Upon completion of work the area shall be checked to secure that no potential dropped objects are left. Inspection of fall arrest harness The user shall always visually check his/her safety harness, - system and anchor point and also have it checked by a coworker. If there is any doubt contact the scaffolding foreman or inspection re. anchor points. Defective harnesses or harnesses that lack the control tag (yearly control) for approved lifting device shall not be used and handed in for repair Use of fall lifeline The anchorage point for the lifeline shall bear a load of 1000kg and the anchorage point should be above the user The lifeline shall be connected to the anchorage point at the approved fall Harness. The rear anchorage point should be used but depending on the work the front anchorage can be used. Normally a self retracting lifeline shall be used Restraint lanyard shall not be used as lifeline Composition of the fall arrest system shall be based on identified risks like: potential pendulum movement, horizontal movement 3 USE OF LADDERS Use Ladders may only be used for access or work of short duration, like installing temporary chain hoists, control and cleaning of F & G detectors Which ladders can be used Ladders shall be in accordance with Chapter VI in the Regulations relating to scaffolding, ladders, work on roofs, etc. Ladders must have rubber knots at both ends and have no visual deformation Only single ladders may be used. Stepladders up to 3.5m, may be used on firm and even foundations when there is no potential for fall to a lower level / sea. Maximum climb height in the ladder is 2m. The 2m shall be clearly marked on the ladder In electrical switchrooms, ladders shall be of non-conducting material Inspection The user is responsible for checking the ladder before use Defective ladders must be discarded 103

5 Safety measures Ladders must be secured to prevent them from sliding or tipping over when used, by a person securing at the bottom until it is secured at the top. During movement on a ladder nothing must be carried in the hands. During work on a ladder three-point contact must be maintained (e.g. 2 feet and one hand). When working, standing above 2 meters fall arrest harness shall be used. 4 SCAFFOLDING Approval of work Erecting/dismantling scaffolding higher than 2m requires a Work Permit level 2. Erecting/dismantling scaffolding lower than 2m requires a general platform/area Work Permit level 2. Erecting/dismantling scaffolding over sea requires approval according to section 6 of this directive. Erecting/dismantling scaffolding Scaffolding shall be erected/moved and dismantled by authorised scaffolders only Scaffolding shall be in accordance with Chapter III of the Regulations relating to scaffolding, ladders, work on roofs, etc. A work platform (including access platforms) shall be secured with handrails and kick plates and other required covering/securing to prevent dropped objects. If this is not possible, the green scafftag shall be marked with necessary safety precautions, such as use of harness and closing of underlaying area. Erecting/dismantling scaffolding over sea When scaffolding is erected/dismantled over sea: the rules for Work over sea shall apply. a Toolbox Talk or Job Safety Analysis shall be performed. there will always be 2 scaffolders. Scaffolding approval Approval of scaffolding for use shall only be performed by authorised approval personnel. Ref. competency requirements, section 1. Approved scaffolding is shown with a green scafftag with date and signature. The scafftag must be at the scaffolding entrance The scaffolding foreman must ensure scaffolds are inspected/approved at least once every 7 days, as well as before and after spells of strong wind or other conditions that may damage the scaffolding 104
