Contractors shall refer to ADNOC HSE Standards, HSE-OS-ST16 and HSE-OS-ST22 for details and necessary compliance.
Minimum Requirements
Contractors shall conduct working at height activities and scaffolding installations by utilizing only competent resources, materials compliant with ADNOC HSE Standards specifications /ADNOC Group requirements.
Any work being performed at height equal to or greater than 1.8 meters is considered as working at height accordingly, extra controls (e.g. Body Harness) shall be placed.
Contractors shall deploy trained and certified personnel to erect, modify and dismantle scaffolding e.g. scaffolding erector, scaffolding supervisor and scaffolding inspector. The identified roles must be independent from one another.
Scaffolding systems must be designed by a competent person and must be erected, modified and dismantled as per ADNOC HSE Standards specifications.
Scaffolding boards and ladders shall be of iron preferably or fire retardant material in the process areas. Contractor shall be required to inspect each scaffold with a competent person before and after any modifications, and after any event that may have affected the scaffold structure.
Scaff-tag system shall be implemented for inspection to display the status of scaffolding.
Wherever rope access is utilized for the activities, Contractor shall follow the ADNOC HSE Standards / ADNOC Group relevant requirements.
Work at height with personnel basket shall be strictly limited (short time work or inspection only). In these cases, the basket and lifting appliances such as cranes shall be of a certified type.
Contractors shall utilize fall protection systems as per ADNOC HSE Standards, ADNOC Group working at height /scaffolding procedures, which includes working over water where applicable. Contractors shall provide adequate number of rescue equipment for working at height.
Contractors shall provide and maintain a safety net system to prevent fall from height (personal/material) wherever required e.g. where there is public interference and distance between adjacent buildings is minimal.
Working at Height means work in any place where, if precautions were not taken, a person could fall a distance liable to cause personal injury. Working at height includes, but not limited to, working:
- On a flat roof;
- On fragile surfaces;
- On scaffoldings;
- Using access equipment (such as, ladders, gangways, cradle, man-basket); and
- At ground level close to holes (e.g. excavations) edges or ledges (e.g. retaining walls).
Extra controls (e.g. Body Harness) shall be placed when working at height is greater or equal to 1.8 meters. Working at height does not include a slip or a trip on the level, as a fall from height has to involve a fall from one level to a lower level, nor does it include walking up and down a permanent staircase in a building. Therefore, it is essential to strictly establish and implement a fall protection strategy while planning to working at height.
Working at height shall be avoided wherever possible. If not, then associated hazards shall be identified and control measures defined during the mandated Job Safety Analysis (JSA).
ADNOC Group shall ensure personnel required for working at height shall be selected as per their ability to perform work Contractors shall submit Medical fitness certificate for personnel assigned to working at height.
