Occupational health risk assessment (OHRA) • Conducted across all project phases to identify and evaluate work-related health hazards and define controls in line with the as low as reasonably practicable (ALARP) principle • Applies a qualitative approach and quantitative exposure monitoring where required to confirm acceptability against occupational exposure limits • Evaluates control effectiveness and implements additional measures where required Control of health risks • Applies the hierarchy of controls: > elimination > substitution > isolation > engineering controls > administrative controls > personal protective controls Information, instruction and training • Provides workers with information, instruction and training on health hazards and affected groups • Includes regular reviews to assess risk levels and control effectiveness Medical examination and health screening • Conducts pre-employment and periodic medical examinations based on age, role and risk • Establishes health screening baseline data and updates throughout employment • Detects early signs of work-related health effects • Repeats screening when job or health changes affect fitness for duty Health surveillance • Confirms fitness for duty based on role-specific risk assessments and industry standards • Includes clinical examinations and biological monitoring where required Compliance / assurance structure • Assesses effectiveness of the occupational health management system through audits and inspections Occupational health risk management Personal safety and work management system ADNOC's personal safety and work management system (WMS) provides the framework through which work activities are planned, authorized and safely executed across our operations. The system integrates International Association of Oil and Gas Producers (IOGP) practices and ADNOC's 10 life-saving rules. It applies equally to employees and contractors, with stop-work authority held by every worker on every site. Following the completion of our digital permit-to-work (PTW) rollout the previous year, in 2025 we extended assurance from system to site through start work checks (SWC), bringing verification of critical controls directly to the worksite. This includes independent confirmation by a second person before activity begins, while integrating human performance principles and review practices that equip supervisors and crews to recognize changing conditions. 10 Life-saving rules Work authorization work with a valid permit when required Confined space obtain authorization before entering a confined space Hot work control flammables and ignition sources Energy isolation verify isolation and zero energy before work begins Working at height protect yourself against a fall when working at height Toxic gas follow the rules for working in toxic gas environments Safe mechanical lifting plan lifting operations and control the area Driving follow safe driving rules Line of fire keep yourself and others out of the line of fire Bypassing safety controls obtain authorization before overriding or disabling safety controls 38
