Safety as a Foundation for Sustainable Growth

The health and safety of our people, communities and business partners is a priority to us. Proactive management of health and safety risks is central to our overall sustainability strategy to ensure operational integrity and long-term value creation.

Our safety approach is guided by a Zero Harm vision and is embedded in our day-to-day operations and behaviour through robust policies, structured risk management, continuous capability building initiatives and active workforce participation.

Strategic Focus Areas

Zero Harm Safety Vision

Occupational health and safety are foundational to our operations and long-term sustainability. We remain committed to building a Zero Harm culture, where safety is not just a compliance obligation but a shared value and a behavioural norm. Zero Harm reflects our belief that every individual, including employees, contractors and partners, has the right to a safe workplace and the responsibility to contribute to it.

Our zero harm vision is reinforced through leadership commitment, participatory processes and continuous improvement. Safety expectations are consistently communicated, driven through training and engagement, and embedded into operational processes.

Policy Commitment

Our health and safety approach is guided by a comprehensive Quality, Health, Safety and Environment (QHSE) policy, approved by the Chief Executive Officer. The policy puts forth clear expectations for safe and healthy working practices across all sites and the supply chain.

Read about our QHSE Policy

Integrated Health and Safety Management System

We operate under a certified Integrated Management System (IMS) that unifies quality, environmental, health and safety requirements into a common framework. This system enables consistent identification, assessment, mitigation and monitoring of risks across all operations. A dedicated QHSE management department oversees the safety performance and ensures its alignment with the health and safety management systems.

Our Key Certifications for Regulatory Alignment

As of FY 2025-26, sites contributing to 74.78% of the Company’s revenue are ISO 45001 certified.

ATGL’s QHSE Policy applies uniformly to all persons engaged in its operations. As documented in the ATGL HSE Manual, the QHSE Policy is formally established, implemented, and maintained across the organisation and is communicated to all employees and contract workers. The policy is disseminated through structured training programmes and is displayed at prominent locations, including in local languages where required, to ensure universal understanding. The management ensures that the policy is understood, implemented, and sustained at all levels, thereby confirming that no segment of the workforce is excluded from its scope.

The Occupational Health and Safety Management System (OHSMS) is applicable to all employees and contractors at ATGL. It defines clear roles, responsibilities, controls, emergency preparedness requirements and performance-monitoring mechanisms. OHSMS enables proactive management of health and safety risks using the hierarchy of controls. Life Saving Safety Rules (LSSR) form part of OHSMS and establish non-negotiable requirements to prevent incident.

Compliance and Audits

We strengthen our compliance with health and safety standards through regular workforce training and mock drills. We undertake periodic audits, both internally and through independent third parties, to seek assurance on compliance with PNGRB regulations, and applicable safety standards covering workplace, asset integrity and Business Partners. These audits provide an opportunity to identify areas for improvement.

Governance and Accountability

Health and safety governance is integrated within our overall corporate governance framework. Oversight is embedded through a multi-tier governance framework that aligns strategic direction, operational execution and frontline accountability. Clearly-defined roles and responsibilities ensure accountability at each level.

The safety committees and task forces operate under dedicated HSE charters and KPIs, and conduct bi-monthly reviews of the safety management system to ensure continuous improvement.

Equal Voices at the Table

Our QHSE policy encourages meaningful consultation with workers and their representatives, ensuring their participation in decision-making whenever required. The Management actively promotes an inclusive culture that supports the effective functioning and continual improvement of the QHSE management system through the involvement and participation of all workers.

• All employees and workers are encouraged to share improvement ideas through suggestion schemes, HSE talks and HSE meetings
• Employees and workers are actively consulted in the identification and assessment of OHS hazards and environmental aspects, and contribute in the development of HSE policies, programmes, operational controls, change management processes, and HSE audits
• Both employees and workers participate in safety committees, where they can raise and contribute to improving HSE practices

ATGL has established formal joint management HSE Committees across all GAs, ensuring active participation of employees and contractor representatives in safety governance. These committees meet monthly to review compliance status, incidents, near misses, emergency preparedness, and contractor safety performance, while also providing a structured platform for workers to contribute to hazard identification, risk assessment, and the formulation or revision of HSE policies and operational controls. Chaired by the GA Head with defined decision-making authority, the committees assign responsibilities, track action closures, and enable transparent and inclusive implementation of ATGL’s HSE management systems.

Transparency in HSE Disclosures

• External communication with interested parties is managed by the concerned HODs/Asset Heads, as relevant and required
• Legal compliances and periodic reports are shared with statutory authorities, as required
• Key QHSE performance updates are disclosed on the Company’s website

Process safety is a critical focus area, given the inherent risks associated with gas distribution and related infrastructure. Our safety practices go beyond routine activities to anticipate and mitigate risks. Critical equipment and systems are continuously monitored, and deviations from normal operating conditions are promptly investigated. Regular safety audits are an integral part of our process safety framework, with insights from audits and near-miss incidents used to strengthen procedures and controls.

Managing Process and Operational Safety

Multiple Layers to Strengthen Operational Safety

Oversight and Accountability in High-Risk Activities

Formal risk assessments are mandatory for high-risk activities, such as gas leaks, fires, or comparable hazards. They are performed either in the presence of the designated Area Emergency Officer (AEO), a supervisor, or a safety engineer, or conducted only after receiving the formal clearance.

Structured Approach to Identify and Manage Safety Hazards

We recognise health and safety as a material sustainability risk. Effective management of occupational health and safety risks reduces the likelihood of serious incidents, regulatory non-compliance and reputational impacts, while strengthening workforce engagement and productivity.

The health and safety risks are systematically identified and managed using a range of structured tools reflecting our risk-prevention approach. These tools are integrated with Hazard Identification and Risk Assessment (HIRA) and Job Safety Analysis (JSA) processes to ensure risks are consistently identified, evaluated and controlled at every level. Routine inspections, surveillance, and reporting ensure hazards are tracked, risks are mitigated, and learnings are applied across the operations continuously.

Tools and Techniques to Identify and Manage Risks

Incident Management

We maintain a transparent and structured framework for reporting and managing incidents, unsafe acts and near misses.

We actively encourage workers to raise safety concerns and report hazards without fear. SAFEX digital platform allows reporting safety incidents and hazards anonymously. Additionally, a safety committee is in place to protect workers from reprisals when reporting incidents, hazards, risks, and improvement opportunities.

Emergency Preparedness and Response

Emergency preparedness is a critical component of our safety risk framework. We have implemented an Emergency Response and Disaster Management Plan (ERDMP) across all geographical areas, in line with the PNGRB requirements. The plan provides a structured approach to risk prevention, emergency response and recovery, safeguarding people, assets and communities. The plan is comprehensively reviewed and updated at a frequency as defined by the PNGRB regulations.

Ensuring Wellbeing of Employees and Workers

ATGL further enhances accessibility to healthcare through telemedicine consultations and online medical support, enabling timely medical attention irrespective of geographical constraints. Onsite wellbeing is strengthened through empanelled hospitals and medical support services, complemented by awareness and wellness programmes such as yoga sessions and health education drives. Together, these initiatives ensure that employees and Business Partners operating in remote areas receive continuous, reliable, and equitable health and wellbeing support aligned with ATGL’s commitment to safe and responsible operations.

Ensuring Workers’ Wellbeing at Remote Sites

ATGL extends its health, safety and wellbeing framework to the last mile, ensuring comprehensive protection for workers across remote and dispersed operational sites through structured wellbeing measures, intended to enhance their quality of life.

Non-Occupational Healthcare for Workers

We extend the health and well-being support beyond the workplace by offering non-occupational benefits, including:

• Life insurance and compensatory packages to permanent employees and workers in the event of death
• Periodic health checkups
• Access to healthcare services through online platform, such as telemedicine consultation and yoga

Extending the Safety Boundary: Business Partners and Supply Chain Safety

Health and safety risks extend beyond our direct operations into the supply chain. To mitigate this, we integrate contractor and supply chain safety into the core Occupational Health and Safety (OHS) framework.

Lifecycle-Based Supply Chain Safety Framework

Strengthening Safety and Sustainability through SAMARTHAN 5.0

ATGL has strengthened the SAMARTHAN 5.0 framework, reinforcing its commitment to continuous improvement, EHS excellence, asset integrity and sustainable contractor practices. With the enhanced CAP categorisation system, we have introduced a new Gold Cap category as the highest level of EHS recognition for both Business Partners and Geographical Areas, followed by Purple, Green, Orange, and Red categories.

Promoting High-Performing and Responsible Partners

Business Partners achieving Gold, Purple, and Green Cap status are recognised as preferred partners, reflecting consistent adherence to safety standards and responsible operational practices. To encourage sustained high performance, ATGL follows a structured and transparent work allocation mechanism. In cases where such partners do not qualify as L1 contractors:

• Preference is extended through the first right of refusal for new contracts
• Opportunity is provided to match auction outcomes during bidding
• 70% of the work scope is awarded to L1 contractors, while 30% is reserved for Purple and Green Cap partners under the SAMARTHAN assessment framework

This approach enables balanced business distribution while actively incentivising partners who demonstrate strong safety culture and sustainability commitment.

Driving Accountability and Risk Mitigation

The Red Cap classification highlights critical safety and compliance gaps. Business Partners receiving two consecutive Red Cap ratings are removed from the system, reflecting ATGL’s zero-tolerance stance to repeated non-performance. This approach strengthens governance, mitigates operational risks, and reaffirms our commitment to protecting people, assets, and the environment.

Strengthening the Safety Culture

From Compliance to Collective Ownership

Safety Culture Framework

Sustaining safety performance requires continuous investment in people and culture. At ATGL, our safety culture is shaped by how people think, act and decide in their everyday operations. We move beyond procedural compliance by empowering our workforce, encouraging dialogue and reinforcing safe behaviours through leadership presence and technology integration.

Capability as a Cultural Anchor

At ATGL, we have institutionalised a structured training and competency development framework, based on training needs identification (TNI) and operational risk profiling, to ensure employees and business partners are equipped to handle role-specific risks.

• A mandatory learning programme for all individuals covering safety induction, refresher sessions, and annual safety programmes
• Risk-based and role-specific training for different skill groups
• Role-based Safety Technical and Operational Competency (STOC) training, covering critical HSE procedures, is mandatory for all business partner’s employees who are engaged in Projects, Operation and Maintenance (O&M) activities across PNG, CNG, Steel, AEO, etc.
• Periodic review of training effectiveness to support continuous improvement

Clear Accountabilities for Safe Performance

Defined roles across the organisation ensure safety responsibilities are well-understood and consistently applied.

• Process owners and Management/HR functions identify competencies for personnel whose activities influence QHSE performance and compliance
• The GA Head ensures personnel can safely perform tasks and identify hazards through appropriate education, training and experience
• The HSE function delivers focused safety and environmental training to employees and the contractor workforce

Engagement That Influences Everyday Behaviour

At ATGL, we meaningfully engage with the workforce to transform safety into a personal value.

• Induction programmes, trainings and regular interactions aligned with ATGL’s vision, mission and safety expectations
• Workforce needs and feedback are considered to strengthen QHSE management
• Celebration of National Safety Week and Road Safety Month, Environment Day, Fire Service week
• Positive behaviours are reinforced through appreciation, rewards and recognition

Digital Enablement for Safer Operations
