'The timber frame is the greener choice because each new frame uses less material.' This is the purchasing team's case for replacing reusable steel transport frames with single-use timber frames. Both protect the same machine equally well during delivery. Which comparison would give the soundest environmental basis for the decision?
Correct answer: B - Compare life-cycle impacts per protected delivery, including frame returns.
Following a dairy's production washout, a river survey finds substantially higher biochemical oxygen demand and lower dissolved oxygen downstream of the outfall than upstream. The same analytical methods were used at both locations. Water temperature, turbidity and river flow show no material change. Which mechanism best fits this pattern?
Correct answer: B - Microbial breakdown of biodegradable material has increased oxygen demand.
An experienced kiln operator has not attended a ceramics plant's new environmental course. A documented practical assessment confirms competence in the site's emission controls, alarm response and environmental reporting duties. No applicable requirement makes that course compulsory. How should the environmental manager address authorization for those assessed duties?
Correct answer: A - Accept the documented evidence of competence for those duties.
Before assigning the solvent-recovery control checks, an internal audit team leader learns that one auditor was the engineer who designed the operating interlocks. Another team member is competent to evaluate them and had no role in their design or operation. How should the work be allocated?
Correct answer: D - Assign the evaluation to the other auditor and obtain design explanations from the designer.
A manufacturer appoints a consultancy to audit its coating supplier against the manufacturer's environmental contract requirements. The supplier reimburses the audit fee under that contract, and the consultancy reports its findings to the manufacturer. No certification decision is involved. This arrangement is a:
Correct answer: C - Second-party audit, because the consultancy acts for the customer.
Winter runoff overflows prompted an airport to redesign the collection system used during aircraft de-icing from November through March. Its annual EMS audit normally takes place in May. A separate readiness review has already verified the new design, equipment and training. The next audit must assess effectiveness in use. When should that evidence be gathered?
Correct answer: C - During winter de-icing, examining performance under the runoff conditions the changes must control.
An electronics manufacturer's procedure requires evidence of receipt by an authorised recovery facility before a waste load is marked 'recovery complete.' Three sampled loads have that status, but available evidence establishes delivery only to the broker's depot. Their onward destinations cannot be established. The broker holds ISO 14001 certification. Which finding is supported?
Correct answer: A - The manufacturer did not demonstrate destination verification for the three sampled loads.
A site's objective is a 10% reduction in electricity use per tonne manufactured on site. The baseline is 600,000 kWh for 5,000 tonnes. This year, electricity use is 630,000 kWh; output records show 4,500 tonnes manufactured on site and 1,500 tonnes bought as finished product for resale. Management divides electricity use by all 6,000 tonnes and reports success. Using the objective's boundary, which result is correct? Round percentages to one decimal place.
Correct answer: C - Intensity worsened by 16.7%, so the objective was missed.
An effluent sample and its field duplicate contain 24 and 25 micrograms/L of lead. Their associated field blank contains 19 micrograms/L; the laboratory blank and check standard pass. The sampling plan allows compliance use only when the associated field blank is below 2 micrograms/L and prohibits blank subtraction. The permit limit is 16 micrograms/L. What is the defensible interpretation?
Correct answer: D - The affected results are unsuitable for this compliance decision under the sampling plan.
During an audit of a chemical store, a hose separates inside the transfer bay, releasing liquid and irritating vapour. The auditor has no spill-response training. Clear access to the alarm point and exit remains. What should the auditor do first?
Correct answer: D - Raise the site alarm and withdraw along the clear evacuation route.
