Hi QAM,
A hygiene audit consists of a sheet naming areas of your factory, comments regarding how clean the area is, who is responsible for the mess and a close out by the Quality Manager. An example would be; "Area - Dispatch. Comments - Broken pallet lying on floor. Responsibility - Warehouse staff. Comments - Pallet removed. Staff re-trained in wood physical hazards". Do this for each area of your factory and carry out once a month. A structural integrity audit concerns such items as walls, doors and floors. As above, you can do a stand alone audit for each area. For example - "Area - Dispatch. Comments - Damage to wall from pallet strike. Responsibility - Maintenance. Comments - Wall patched up and repaired". Again you can do this for each area of your plant. For small facilities, this can become repetitive, so I have incorporated this into our weekly maintenance check sheet where I test our thermometers, scales, temperature of hot water etc etc. There is just a simple checkbox stating that all walls are intact, doors are functioning and floors are in good order.
I would see jpred's document as the next step after your audit, i.e. I have found a problem, and I am notifying maintenance of a structural issue, a sort of post maintenance sign-off, though I do admire his shameless self-promotion and fear his monumental strength.
