Hi there, do any of you have equipment that has a lot of bolts and screws, and do you have an inventory of those bolts and screws that you check before the beginning of each run, to make sure they haven't fallen into product?

 

We have a metal detection system in place in multiple places, and I'm sure we would find a bolt or a screw if it fell into product.  However, the missing bolt or screw could cause adverse equipment performance as well.

 

What do you think?

 

Matthew

No we don't.  We have a prestart check but to have an inventory of every nut and bolt is OTT IMO.  If there are some nuts or bolts deliberately removed from a machine then you could mark the machine to make this clear.  If you have had issues with it, then risk assess where the risk is highest and concentrate on these, otherwise you risk giving your teams so much to do they don't actually do it and it becomes a tick box exercise.

Definitivelly, do it!

See BRC 4.7.2: In addition to any planned maintenance programme, where there is a risk of product contamination by foreign bodies arising from equipment damage, the equipment shall be inspected at predetermined intervals, inspection results documented and appropriate action taken.

Interpretation Equipment inspection
Where there is a risk of foreign bodies contaminating product due to wear or damage to equipment or pieces of machinery (e.g. sieves, mills, equipment covers etc.), there must be a periodic check of the equipment. This may be achieved by a documented check procedure carried out at defined intervals (e.g. at process start-up, at start of shift, during product changeover, and after cleaning or maintenance).
Inspection results must be documented and, where appropriate, action taken.
best regards,
Leila
