The objective for the work procedure (ref. classification sheet no,): K 1.70.076 Prevent personnel injury from using fall arrest harness and associated equipment.

Identified dangers (ref. classification sheet no,): K 1.70.076 1. Lack of competence in inspection, control and use of fall arrest harness and lines. 2. Uses anchor points of less strength than 1000kg load bearing capacity. 3. Incorrect limitation in use of equipment in relation to fall distance to protruding equipment or swinging

can result in collision and hurt oneself. 4. If hanging for a long time in fall protection harness one can get circulation failure if one does not get to

use relief (leg) strap. (Hang trauma) References: (Refers to relevant laws, regulations and BP’s directives, manuals, HMS-instructions, vendor’s documents, datasheet for chemicals and other dangerous substances,) Governing documents: 8 Golden Safety Rules – Permit to Work, Working at Hights; HSE directive 1

Check list for use of fall arrest harness / working in height Check points N/A YES NO Comments

1. Are you using a full body harness with double latch self-locking snap hooks and equipment with relief strap / foot strap?

2. Has a proper anchor point for the safety line been located?

3. Is fall arrest equipment in use that will limit the free fall to 2 meters or less?

4. Has the fall arrest equipment been visually checked for:

- damage/wear or defects? - control tag with the latest control date?

5. If a ladder is used, is the ladder free of visual damage and secured? During securing of the ladder one person shall secure the ladder at the bottom until the ladder is secured at the top

6. Has the fall arrest equipment, system and anchor point been checked by a colleague?

7. Is there a person in the work area that can initiate basic rescue, if a fall should occur?

8. Are equipment / tools used at height controlled and adequately secured against dropping? And not left behind finishing the work?

9. Are underlying areas closed off and pressurized/sensitive equipment protected against dropped objects?

10. Are lighting, noise and weather conditions satisfactory for the task?

11. Are there any other risks and have they been evaluated and found acceptable? Use the 4 – Point Risk assessment

12. Have the involved persons completed a course in fall arrest methods?

13. Have all items on the checklist been answered YES without comments? If NO, the work shall not be started. Contact the line manager to find alternative methods to perform the work.

ADDITIONAL COMMENTS : Note! Work over open sea also require the use of “Duties for the safety guard during work over sea” (attachment1) Date: Area technician (Work w/o WP): Performing technician(s): Closure of work
