EMS Auditing Principles & Techniques 2 — Questions and Answers
Question 1: During an EMS audit, an auditor discovers that an employee verbally described a procedure that differs from the written document. What is the most appropriate immediate action?
- Disqualify the employee's testimony entirely
- Record the discrepancy as an objective finding and verify with additional evidence (Correct answer)
- Immediately issue a nonconformity without further investigation
- Inform management and end the audit interview
Correct answer: Record the discrepancy as an objective finding and verify with additional evidence
Auditors must gather objective evidence from multiple sources before drawing conclusions, so discrepancies should be recorded and further verified.
Question 2: Which sampling method is most appropriate when an auditor wants to ensure that records from each operational department are included in an EMS audit sample?
- Random sampling
- Judgmental sampling
- Stratified sampling (Correct answer)
- Systematic sampling
Correct answer: Stratified sampling
Stratified sampling divides the population into subgroups (strata) and samples from each, ensuring all departments are represented.
Question 3: An audit team leader notices a potential conflict of interest because one auditor previously worked in the department being audited. What should the team leader do?
- Allow the auditor to participate but supervise closely
- Reassign or replace that auditor for the affected area (Correct answer)
- Have the auditor only review documents, not conduct interviews
- Proceed with the audit since the auditor left that department
Correct answer: Reassign or replace that auditor for the affected area
ISO 19011 requires auditors to be impartial, and prior employment in the audited area creates a conflict that typically requires reassignment.
Question 4: What is the PRIMARY purpose of an audit trail in EMS internal auditing?
- To document auditor hours for billing purposes
- To provide a verifiable chain of evidence linking findings to objective data (Correct answer)
- To create a chronological log of auditor travel
- To track corrective action deadlines
Correct answer: To provide a verifiable chain of evidence linking findings to objective data
An audit trail connects each finding back to specific, verifiable objective evidence, ensuring conclusions are defensible and reproducible.
Question 5: Which of the following BEST describes the difference between a 'finding' and a 'conclusion' in an EMS audit?
- A finding is the final audit report; a conclusion is an individual observation
- A finding is based on objective evidence; a conclusion is the auditor's overall judgment after evaluating all findings (Correct answer)
- A finding is a major nonconformity; a conclusion is a minor nonconformity
- A finding is verbal; a conclusion is written
Correct answer: A finding is based on objective evidence; a conclusion is the auditor's overall judgment after evaluating all findings
Findings are specific results based on objective evidence, while conclusions are the overall professional judgments the audit team draws from those findings.
Question 6: An auditor is reviewing EMS legal compliance records and finds several environmental permits that have expired. Under which audit finding category does this BEST fall?
- Observation
- Opportunity for improvement
- Nonconformity (Correct answer)
- Positive finding
Correct answer: Nonconformity
Expired permits indicate a failure to meet a legal compliance obligation, which is a clear nonconformity against ISO 14001 Clause 9.1.2.
Question 7: When using the process approach during an EMS audit, what does the auditor primarily evaluate?
- The organizational chart and reporting hierarchy
- How inputs are transformed to outputs and whether controls are effective (Correct answer)
- The number of environmental incidents per year
- The qualifications listed on employee resumes
Correct answer: How inputs are transformed to outputs and whether controls are effective
The process approach examines inputs, activities, outputs, and the effectiveness of controls within each process to determine conformance.
