HSE DIRECTIVE 3 WORKING AT AT HEIG HEIGHTS HTS

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 Scope 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.

2. WORKING AT HEIGHTS Use of safety devices • all work carried out standing with one’s feet 2 metres or more above the deck requires: o fixed platform with handrail, or o scaffolding with green scafftag, or o use 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 o filled 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 support line. • When using fall arrest equipment • at least one person shall be present in the area nearby at all times in order to start rescue work and alert the necessary persons in case of a fall • prior to commencement of work, a realistic and safe rescue plan shall exist. The 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. • If dropped objects can damage pressurised equipment, the area shall be physically protected or de-pressurised in co-operation 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. • Defect harnesses or harnesses that lack the control tag (yearly control) for approved lifting device shall not be used and handed in for repair Fall arrest line • Anchor points for fall arrest harnesses shall as a guideline at least hold 1000kg, and the point shall preferably be above the user HEALTH, SAFETY & ENVIRONMENT HANDBOOK 2008

Fall arrest lines shall only be fastened in a D-ring on the person’s back with the fall arrest harness When using fall arrest lines a fall block shall normally be used. Support lines (without shock absorber) must not be used as fall arrest lines for safety harnesses as they are only intended as extra support to be used together with safety harnesses and support belt The compilation of the fall arrester equipment shall be assessed based on the nature of work (e.g. take into considerations like movements in the horizontal movements and potential pendulum movement

3. USE OF LADDERS Use • Ladders may only be used for access or work of short duration 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 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 in a ladder nothing must be carried in the hands. • During work in a ladder three-point contact must be maintained (e.g. 2 feet and one hand) and fall arrest equipment used when standing above 2 meters.

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 5 of this directive.

98


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. • 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 14 days, as well as after spells of strong wind or other conditions that may damage the scaffolding Use of scaffolding • Only scaffolding having a green scafftag is approved for use • Scaffolding must be used in accordance with limitations given on the green scafftag .

5. WORK OVER OPEN SEA Introduction • Work over sea means work taking place outside permanent railing where there is a risk of a person/persons falling into the sea. • Work in hydraulic basket in “moon pool” and on approved scaffolding is not defined as work over sea when extra barriers such as • fall arrest equipment • man-riding belt • net • Scaffolding build as a class 3 and certified as a class 2 scaffolding with extra heighten hand rail (railing). The scaffolding shall be certified every week and inspected after external influence e.g. strong wind Note: use of fall arrest equipment, man-riding belt or net requires independent securing. (not attached to the scaffolding). HEALTH, SAFETY & ENVIRONMENT HANDBOOK 2008

Approval • Work over sea requires an approved work permit level 1 Restrictions Work over sea is permitted provided: • The wind speed is maximum 30 knots, measured at a 10 m level • The wave height is maximum 5 m (corresponds to 3 m significant wave height) • Standby vessel in near-standby mode or MOB in extra preparedness mode • The MOB boat onboard or on the standby vessel is operative and can be launched/retrieved in case a person falls into the sea • The light and view is good enough to perform the work and rescue any person that may fall into the sea • Consent has been obtained from the diving supervisor if there is diving activity near the work site Safety precautions • When working over sea, a safety guard must be present and monitor the personnel located over sea at all times. The safety guard shall be familiar with and carry out tasks stated in the Safety guard’s duties in connection with work over sea • A life buoy with line and light shall be easily available • The performing personnel shall be familiar with all procedures, preconditions, risks and safety precautions relating to the work • Everyone working over open sea shall wear a life vest • When working below the cellar deck, consider whether to secure spills, overflow, etc. from e.g. fire water • Consider the need for implementing measures to avoid objects falling to lower levels or down on vessels.
