1. Work at Height and Over Water - Awareness QHSE Department 06 February 2013 Doc. Control No.: HQS-016-17-003 Rev 1

2. Learning Objectives • At the completion of this session, personnel should be able to: • Describe Songa Offshore’s required safe working practices for working at height and over water. • Locate on the QSMS, the Songa Offshore “Working at Heights” and “Work Over Water Procedure”.

3. Work at Height Procedures Corporate Level • Working at Heights, • Work Over Water Procedure, & • Man-riding procedure, is located on Level 4 - QSMS. • The Man-Riding & Work at Height Review checklists are located on, Level 7 - Corporate QSMS. Regional Level Rig Level

4. What is Work at Height? • Work at heights is applicable, where the feet are at a height of 2 meters (6 1/2 feet) or more above the nearest floor or where fall hazards exist.

5. Planning All work at height can be accomplished without any risk of falling. By careful planning, completing a risk assessment and adhering to the fall protection hierarchy: • Remove the hazard: Bring the work down to the ground level whenever possible. • If work at heights is unavoidable, secure the elevated work area with a barrier system, such as guardrails. • When a barrier system is not feasible, use an approved fall restraint system. • If no other option is feasible, use a approved fall arrest system and rescue plan.

6. Risk Assessment for Work at Height What risk management tools do we use, to properly plan and organise working at height tasks? • Development of Job Safety Analysis (JSA), • Safe work procedures, and • Planned equipment inspections

7. Risk Assessment for Work at Height • A Job Safety Analysis (JSA) shall be planned prior to the task being performed. • The work at height review checklist (HQS-017-21-006), can be used to assist in the development of the JSA. The Head of department, Supervisor and person performing the work will determine whether a Permit to Work is required for other critical work at height tasks. E.g. Work over water, Mobile elevated work platform.

8. JSA - What are the Job Steps, Work Environment and Conditions? Your basic steps should cover these?

9. JSA - What are the Hazards and Causes for Each Step? Has the JSA or work at height review checklist been used?

10. JSA - Determine the Potential Consequences? What could they fall – onto or through? How far could they fall? Dropped objects? What are the possible consequences to PEOPLE, Environment and Equipment?

11. JSA - Develop Control Measures Eliminate – bring work down to ground level Isolate - barriers / guard rails, tethered tools Engineer – Fall restraint, Fall Arrest systems Administration - training PPE – hard hat, harnesses

12. Personal Protective Equipment • What PPE is mandatory, when working at height? • Approved full-body harness is to be worn • Approved fall restraint or fall arrest system is to be worn • A chin strap is to be fitted and worn on protective hard hats. • All hand tools and equipment are to be fitted with a lanyard or tether to prevent dropping.

13. Fall Restraint • Fall restraint is the preferred approach to fall protection – it prevents you from falling by preventing you from entering an area of where a risk of fall from height exists.

14. Fall Arrest • Fall arrest is an approach which makes use of items of PPE to stop a falling person. • This means that if a worker is in a position where they could fall, the fall arrest system will limit both the distance and force of that fall.

15. Fall Clearance • An often overlooked hazard is that of fall clearances. You must ensure there is sufficient distance beneath the user to ensure they do not hit a lower level, or the ground, before the fall arrest system is fully deployed.

16. General Precautions • Avoid working on two levels at the same time to prevent the risk of dropped or falling objects. • Secure loose objects from falling at all times; • Check equipment thoroughly for loose parts before lifting overhead. • Ensure all loose tools, equipment, and parts are removed or secured when stopping work. • All deck openings will be covered, guarded, or made inaccessible.

17. General Rules for Derrick Work What are the rules wemustapply to reduce the risks associated with working in the derrick? • The following general rules for derrick work are to be adhered to: • Do not enter the derrick without the Driller’s permission. • No work is initiated in the derrick before the Driller notifies Drill crew & well is safeguarded against falling objects. • All equipment being carried into the derrick is to be logged in and out of the derrick register. • All tools to be used are to be fitted with a safety lanyard to arrest any fall, prior to going up the derrick.

18. Safe Use of Ladders • Types of Ladders: • Commonly used fixed ladder (used daily) • Potential for a fall over 2 meters / 6 ft • Fitted with an appropriate permanently fixed fall arrest system. • Signage is to be located to prompt the climber to use fall arrest.

19. Safe Use of Ladders • Types of Ladders: • Infrequently used ladders (not used daily) • Not used daily or not specifically for emergency escape and present a free fall hazard of over 2 meters or 6 ft. • Temporary fall arrest system shall be fitted. • Signage is to be located to prompt the climber of control measures required.

20. Safe Use of Ladders • Types of Ladders: • Emergency Ladders • Marked with the appropriate IMO pictogram. • A risk assessment for the fall hazard on these ladders will be provided to determine requirements to prevent fall.

21. Safe Use of Step Ladders • All ladders are to be constructed of non conductive material. • All ladders must conform to regulatory standards. • Inspect the ladder before use; do not use a defective ladder • Ensure the ladder is the proper length for the job to be performed. • Ladder should rise to a height of at least 3½ feet (1 meter) above the landing place. • Ensure that the ladder or stepladder is securely supported.

22. Safe Use of Ladders • The Distance between the ladder base and the supporting structure should be one (1) meter for every four (4) meters of working ladder height. • This is referred to as the “Pitch angle” which for ladders is = 1 - 4

23. Mobile Elevating Work Platforms • A competent person shall be designated to operate the work platform, scissor lift, cherry picker, crane lift platform. • Supervisors and competent persons operating MEWPs must assess the risks of people falling from or being thrown from the carrier, or the MEWP overturning, and eliminate or control those risks. • If there is still a residual risk of impact or persons falling, then the use of fall should be used.

24. Mobile Elevating Work Platforms • Checks should be made with the manufacturer that the MEWP can be used as part of a fall arrest system and that it has suitable anchor points? • Note: When working next to water, a harness should not be worn due to the risk of drowning. Life jackets should be worn.

25. Suspension Trauma • Potentially fatal consequences that may be experienced by workers using fall arrest systems. • The sustained immobility may lead to a state of unconsciousness, venous pooling and can result in death.

26. Emergency Preparedness After a person’s fall has been arrested, how are you going to rescue them? • A rope rescue team shall be established on all Songa rigs and emergency rescue plan shall be in place prior to work commencing. • Rescue personnel must by trained, competent, clearly identified and have the correct equipment and be able to perform their responsibilities
