Thanks a lot for your answers and tips. They are very helpful with our implementation of BRC.
I just thought of another issue with our uniform policy that might cause a problem for us. We do not have an actual locker room for changing, it's more like part of the plant that is sectioned off with lockers. Would be worth the time and money to put up a wall and segregate the locker room and make the employees change into their uniforms when they get to work?
I'm guessing from your descriptions that it's a small site? To be pragmatic; perhaps it would be a good idea to review what you're asking them to wear before building walls. I'm guessing from your description, the team are changing fully. I would question, is that necessary? Most high risk food manufacturers I know use long sleeved coats which are at least knee length and fully cover the person's clothing. This has the benefit that it can be put on hygienically (you can't hygienically put on trousers as they drag on the floor) and also can be easily removed for breaks etc. You could still provide other workwear if you want to but it would be the coat which is the "hygienic" workwear.
Also it's good practice to have a gowning procedure; this is to minimise the risk of hair contamination and ensure hands are clean. This is what I'd expect ideally for a RTE plant but in practice this level of control is only normally in place in chilled factories.
Remove outside clothing where necessary (e.g. coats) and hang in a dedicated area (eg a coat rack or dedicated locker)
If you have dedicated footwear for the area, remove outside footwear
Put on mobcap
You may chose to have a physical barrier into the production area like a bench; in which case swing your legs over the bench
Put on your dedicated footwear (if used)
Wash hands with soap and sanitiser
Dry hands thoroughly
Put on dedicated coat for production area
Wash hands again (or just use sanitiser; you can decide on the risk here)
Enter production area
