Hi Skye,
I'm afraid I agree with GMO on this issue . . and I've got to say that if I were a BRC auditor (have done them in the past . . long, long ago, in another galaxy . . ) I would be giving you a minor on the washing of protective clothing at home and wearing it to come to work and unfortunately, possibly a major for the contamination risk to the processed product from the clothing and dust.
You say that the staff come to work in their protective clothing underneath their outer clothing and then remove their outer clothing and leave it in a portacabin. Would it not be better for the staff to come to work in their normal clothes, change into protective clothing provided for them in the portacabin and then make their way into the processing area? If you have a laundry service, the protective clothing can then be laundered and kept in the portacabin.
In terms of health and safety, to have your staff changing into protective footwear after they have moved through the potato warehouse might also pose a forseeable risk to safety.
IMHO clause 7.4.3 is intended to deal with the situation where the protective clothing only performs one function, to protect the worker from the product or from other materials, for example if the product is a corrosive/toxic chemical contained in packaging, but with the risk of residual chemical on the packaging or risk of soillage/breakage or for example in engineering areas or loading bays (low risk areas). I don't think it is intended for use in areas where low risk food processing is carried on.
In terms of the contamination risk from warehouse generated dust, I am assuming that you use forklift trucks and rollertrucks to move pallets around and stack them, and although you don't mention it, from what you do say, I have a feeling that deliveries of potatoes and finished processed product go straight into/out of the warehouse through the same entrance as the staff. If this is the case then the risk isn't just dust from the potatoes in the warehouse. There may also be a risk from external dust, airborne debris, vehicle exhaust emissions etc.
Producing peeled and chipped potatoes means that you may be treating the peeled/chipped potatoes in some way to de-contaminate them during processing, perhaps with water containing Sulphur Dioxide or raised levels of Chlorine? The dust from potatoes in the warehouse isn't just potato dust, its basically the earth they were grown in and small fragments of potato skin, other dust particles and airborne debris, and is very likley to contain all the bacteria, viruses, moulds, fungi etc., normally found in soil, including food poisoning bacteria. Having the potential for this dust/debri to to get into the processing area and the processed product, either on personnel protective clothing, or just simply by being airborne, is something which the auditor may consider to be a major deviation. From your company's point of view too, if the product is being contaminated by the dust/debris, then you are probably wasting your money on de-contaminating the product during processing because the presence of the dust defeats the object of doing this.
Again, IMHO, I would either have the production area accesses totally separated from the warehouse, or at least, have an intervening ventilated space in the access to the production area to mitigate the risk of dust getting into the production area, using a slight positive pressure in the IVS. Both of these would then permit staff changing into protective clothing adjacent to the production area without the need for them to expose their protective clothing to contamination by walking through the warehouse. If you were able to re-position the portacabin to an external wall of the processing area, you might be able to open up an access route with an IVS thay way and seal off the access from the warehouse. This would achieve all the objectives of the requirements and improve staff/warehouse safety too.
AS GMO says, having a risk assessment won't prevent the auditor from giving you a minor (or a major) contravention, if the risk is still present. It might actually make things worse, because you have identified a problem and haven't done anything about it other than document the risks . . and in truth this may incur another contravention. Whereas, making the relatively small investment, might present added business opportunties for the company, not just with people like Northern Foods, Samworth, Bakkavor, Kerry Foods etc, but also the NHS, Education Authorites (schools) and Social Services/meals on wheels, Univerisites and Colleges, large residential care home businesses and distributors such as Brake Brothers and 3663, and you could also increase your catalogue of finished processed product to include other vegetables/fruit as well.
Anyway, apologies for rattling on a bit! Nuff' said!
