Case: Audit visited store, it's raining.

After reaching at store, in such case, the auditor can start collecting and recording audit information for provided resources and training for space management regarding the issue. Some information can be obtained while in the office (ie, viewing or photocopying records) and the rest can be obtained during the site inspection. The following tasks should be completed during the site inspection:

• gather information—take notes, ask open questions (you may wish to review the notes with the interviewee at the conclusion)  

• document any observed environmental/conservation issues which were not anticipated during the preparation of the audit checklists

• take a photographic record (always inform the store incharge or their representative of your intention of taking photographs during the audit)

• examine relevant documents, eg, monitoring records, written procedures, site plans, process diagrams

• obtain copies of any documents which may be useful.

When auditing, it is often not possible, due to limited resources, to check every document or record. The auditor should consider how much documentation should be viewed. The auditor may choose to sample a statistically representative number of documented results, such as monitoring data or incident reports. An appropriate sampling method will manage any uncertainty to an acceptable level.

However, if the facility being audited has limits on discharges, and a discharge is occurring and there is some uncertainty about the discharge’s quality, the auditor may decide to take a sample to determine compliance with the limit condition. In this case, the auditor must collect a sample that represents the condition being assessed and must collect it in a manner consistent with the collection, handling and preservation principles.
