Preview — answers shown1. Which of the following is NOT a fundamental audit principle outlined in ISO 19011? (Select one!)
Explanation
The seven audit principles in ISO 19011 are integrity, fair presentation, due professional care, confidentiality, independence, evidence-based approach, and risk-based approach. 'Legal compliance' is an objective of the audit or a requirement of the standard being audited, but it is not itself an audit principle. The principles guide the auditor's behavior and methodology, not the specific subject matter of compliance.
2. In the context of ISO 14001:2026, which new clause specifically addresses the planning of changes to the environmental management system? (Select one!)
Explanation
ISO 14001:2026 introduces Clause 6.3, 'Planning of changes,' as a specific requirement to ensure changes to the EMS are planned and managed. Clause 6.1.2 relates to environmental aspects, Clause 8.1 to operational planning and control, and Clause 9.3 to management review. This new clause formalizes the need to consider changes systematically.
3. The EMS coordinator, who manages the waste management process, is assigned to audit that same process. Which audit principle is violated? (Select one!)
Explanation
Independence requires that auditors be free from bias and conflict of interest, meaning they cannot audit their own work. Even in internal audits, the auditor must be independent of the process being audited. Integrity relates to honesty, confidentiality to information security, and fair presentation to accurate reporting, none of which are the primary violation here.
4. The auditor observes that the organization has not updated its environmental aspects register to include a newly installed boiler. Which PDCA phase is primarily affected by this omission? (Select one!)
Explanation
Identifying environmental aspects and determining their significance occurs in the Planning phase (Clause 6). Failing to identify a new aspect means the planning process is incomplete. The Do phase implements controls, Check evaluates performance, and Act addresses nonconformities. The root issue is the lack of planning for the new aspect.
5. An auditor discovers that the organization has not established an environmental policy, which is a mandatory requirement. How should this finding be classified? (Select one!)
Explanation
A major nonconformity is defined as the absence of a required element or a systemic failure. Since the environmental policy is a mandatory requirement of ISO 14001, its absence constitutes a major nonconformity. Minor nonconformities are isolated departures, while observations and anomalies do not represent clear violations of mandatory requirements.
