Identify the object first
Different facilities may be governed by different anti-terrorism security requirements. Start with the legal status, use, owner or operator, visitors and the specific sectoral rules.
Keep the assessment record
Retain the commission documents, factual information used for assessment, decisions, security passport where required and evidence of implemented measures. A category should follow the current procedure, not a generic online template.
Review after material changes
A change in use, operator, layout or risk profile may require the assessment to be revisited. Check the current competent authority and deadline for the object concerned.
When a dispute arises
For a notice, fine or disagreement with categorisation, review the inspection record, governing act, facts and procedural timing before deciding on an administrative response.
