The audit question
Your wash hall runs 200 batches a month. An auditor picks a sample and asks for the temperature record for each one. If the record is missing, incomplete, or manually entered with no corroboration, that batch is a compliance finding — and every garment in it has a gap in its wash history.
ISO 15797 governs how fire service PPE must be washed to preserve its protective properties. The standard covers temperature, wash programmes, and chemical compatibility. Your wash hall probably meets the standard. The question is whether your records prove it.
