What is the primary objective of ISO 45001?

ISO 45001 specifies requirements for an Occupational Health and Safety Management System (OHSMS) to prevent work-related injury and ill health and proactively improve OH&S performance. It follows the Plan-Do-Check-Act (PDCA) cycle across Clauses 4–10, embedding OH&S into business processes via context analysis, leadership accountability, risk-based planning, operational controls, performance evaluation, and continual improvement.

Who is legally or professionally required to comply with ISO 45001?

No organizations are legally required to comply with ISO 45001, as it is a voluntary international standard applicable to any size or sector. It is professionally adopted by high-risk industries like construction, manufacturing, and oil & gas to demonstrate due diligence, meet supply-chain expectations, reduce incidents, and integrate with management systems, scalable from SMEs to multinationals.

Does ISO 45001 require an external audit or third-party certification?

ISO 45001 does not require external audits or third-party certification, which remains voluntary. Organizations must conduct internal audits (Clause 9.2) and management reviews (Clause 9.3) to evaluate OHSMS effectiveness; certification via accredited bodies involves Stage 1 (documentation) and Stage 2 (effectiveness) audits, followed by annual surveillance and triennial recertification.

How often should an assessment for ISO 45001 be performed?

ISO 45001 requires internal audits at planned intervals based on risk, status, and results (Clause 9.2), with no fixed frequency specified. Management reviews occur at planned intervals (Clause 9.3), typically annually or when significant changes arise; monitoring and measurement (Clause 9.1) are ongoing, using leading/lagging KPIs like near-miss rates and LTIFR.

What are the consequences of non-compliance with ISO 45001?

Non-compliance with ISO 45001 carries no direct penalties, as it is voluntary, but exposes organizations to regulatory fines, litigation, and operational risks from unmet legal OH&S obligations. Failure to implement effective OHSMS may result in incidents causing production losses, higher insurance premiums, reputational damage, and supply-chain disqualification.

Can ISO 45001 be mapped to other international frameworks?

Yes, ISO 45001 aligns with other ISO management system standards via its High-Level Structure (Annex SL). Common clauses (e.g., context in Clause 4, support in Clause 7, performance evaluation in Clause 9) enable integrated management systems, streamlining audits, documentation, and reviews while preserving OH&S-specific requirements like worker participation and hierarchy of controls.

What is the first step to begin implementing ISO 45001?

The first step is understanding the organization's context and conducting a gap analysis against Clauses 4–10 (Clause 4). Secure top-management commitment, analyze internal/external issues and interested parties, define OHSMS scope, and produce a prioritized roadmap for leadership, planning, and operational rollout.

What is the primary objective of EN 1090?

EN 1090 ensures controlled execution and conformity assessment of structural steel and aluminium components for CE marking under the Construction Products Regulation (CPR). It comprises EN 1090-1 (conformity assessment via certified Factory Production Control (FPC) and Declaration of Performance (DoP)), EN 1090-2 (technical requirements for steel structures including welding, tolerances, and inspection), and EN 1090-3 (parallel requirements for aluminium). Risk-based Execution Classes (EXC1–EXC4) scale controls for consequence class (CC1–CC3), service category (SC1–SC2), and production category (PC1–PC2), enabling market placement in the EEA.

Who is legally or professionally required to comply with EN 1090?

Manufacturers of load-bearing steel and aluminium structural components and kits for permanent incorporation in construction works must comply with EN 1090 to affix CE marking. This applies to fabricators, welding shops, and suppliers targeting EU/EEA markets, covering applications like buildings, bridges, and industrial structures. Non-structural or non-metallic elements are excluded; EXC determination dictates scope based on failure risk.

Does EN 1090 require an external audit or third-party certification?

Yes, EN 1090-1 mandates certification of the FPC system by a Notified Body via AVCP systems (e.g., 2+), including initial inspection, type testing/calculation (ITT/ITC), and ongoing surveillance audits. Certification enables lawful CE marking and DoP issuance; manufacturers handle ITT/ITC, while Notified Bodies verify FPC effectiveness and conduct periodic audits scaled to EXC.

How often should an assessment for EN 1090 be performed?

FPC surveillance audits by Notified Bodies occur annually or per EN 1090-1 Table B.3, scaled by EXC and prior performance, with initial surveillance typically one year post-certification. Manufacturers must conduct internal audits continuously, addressing non-conformities within 30–90 days; changes to processes, personnel, or products trigger re-assessments.

What are the consequences of non-compliance with EN 1090?

Non-compliance prevents CE marking, blocking EEA market access and risking product withdrawal, fines, or liability under CPR. Notified Bodies may suspend/revoke FPC certificates for major non-conformities, publicizing status; failures expose manufacturers to civil claims, rework costs, and reputational damage from structural incidents.

Can EN 1090 be mapped to other international frameworks?

No, these FAQs address EN 1090 independently per scope; standalone compliance focuses on its CPR-harmonized requirements without external mappings.

What is the first step to begin implementing EN 1090?

Conduct a product scope and EXC assessment to confirm applicability and default to EXC2 if unspecified. Appoint a Responsible Welding Coordinator, perform gap analysis against FPC requirements, and engage a Notified Body early for documentation review.
