Hi,

 

I'm looking for some advice on external doors. I've only been at the site a month and am working on implementing BRC, but I'm not very experienced. We are a paper packaging company which now deal with food contact grease proof papers and the site is still under development, as we have just moved in about a year ago.

 

I have a bit of an issue with external fire doors leading into the production/hygiene areas. In the hot weather (not that we get a lot of that here!) the factory gets very hot so the doors are left open, although they shouldn't be, to make it more comfortable for the operators. This obviously opens us up to contaminants and pests entering so I wondered about having fly/pest doors fitted internally which should hopefully keep out pests but still allow some ventilation through the mesh.

 

My question is would something like this fly with BRC?

 

Thanks in advance!

I like the gag!  "Would this fly?"  Nice!

 

The answer is yes, possibly, with notes of caution.  If you have close fitting fly screens with no risks that flies, birds and rodents can enter (remember those brush strips) then yes, it can be acceptable from a pest perspective, but...

 

Remember doors aren't just there to keep pests out but to stop people who shouldn't be at site getting in.  Fly screens are less likely to be lockable, especially if they're over fire doors and even if they are, they're far easier to cut through to access.

 

So in summary, yes, possibly but if you do, make sure that the doors you do screen are within a secure site perimeter so that they couldn't be used as access (so not a food defence issue) but you'd also need to make sure they're closed up when the plant is shut down.

Hmmm I can't see this "flyiing" to be honest as it's bad on a number of levels as GMO has pointed out. Do a really thorough risk assessmen,t bring pest cotrol, hygiene, site security, food defence etc into it and see how you feel after that. If the fly screens were able to be fixed then it might be a runner but as they are emergency exits this can't happen either unless you put seals on them maybe or alarms? 

 

Any chance you can get AC? 


I'm entitled to my opinion, even a stopped clock is right twice a day

Thanks both for your replies. I think the doors would be probably just like the fire doors (which aren't actually sealed around the edges) but with mesh. We could definitely fit brushes etc.

 

I doubt it with AC, we are not a big manufacturer and it would be costly I would imagine.

 

It's a bit of a awkward one, I'm going to try and contact BRC and see if they can offer any advice on it also but open to any suggestions!

 

This is such a great resource, esp for someone new to BRC like myself.

I've had two low risk sites with, admittedly previous versions of BRC but we had fly screens over doors and it wasn't raised as an issue.  It wouldn't be acceptable in high care / high risk and you'd need to think security but otherwise I see nothing in BRC which prevents it.

We (packaging supplier) have fly screens on a couple of external doors with a very fine mesh and there are brush bars on the bottom. 
AC not possible in some areas and the heat is an issue occasionally.
It's never been raised at audit. We are a basic hygiene site. 
The site is secure so the issue of intruders isn't an option and we included it on a risk assessment which included reviewing pest control results, site security, hygiene etc.

If you can manage to exclude pests with screens. Yes.

If you can manage to show an auditor that unauthorized people will NOT access your facility through open doors. Yes.

If you can't show that unauthorized people will NOT access your facility through open doors. No.

what about exhaust fans which will remove hot air from the room??

To get round the issue of intruders, I don't know if we could alarm the fly/screen doors?

Install stand alone/industrial air conditioners.

The problem with installing exhaust vents is installing them. I have no idea about your building make up, but generally they are installed in the ceiling or high up on a non-load bearing wall.
Is the roof capable of handling the weight of the exhaust units? If you want to put them in the walls, structurally, is it possible?

What will you do to ensure food safety when holes are being cut in your facility?
Since you are a packaging manufacturer, you don't have to deal with the change in air flow, which would otherwise be an issue for facilities with allergen concerns.

 

I guess I have been working in the industry too long. When I hear people complain about how hot it is in the facility, my glib answer is "It's a bakery. It's not a bank" :)

On the whole, there is nothing against it providing they are properly fitted and they work. You might fall foul of fire and other H&S risk assessments so so think it through noting what other means of staff egress are available.

 

You can demonstrate their efficacy by showing EFK counts before and after installation. 

 

Of course, as it is BRC, risk analysis comes into play so update this and a statement from your pest controller will help in the justification. (I once had a non conformity for not having a risk assessment for removing a self closing mechanism from a door on the advice of the fire brigade).

 

It will also, as mentioned, impact on security so don't forget to review and update your security risk assessment.

Thanks all, I'll get RA up to date for all the areas. For security I would like to alarm the screen doors but not lock (as they will be fitted in front of fire doors).

We've installed screen doors in addition to all of our overhead garage doors in our plant. It is terribly hot in our region of the US and the screens are down all summer long during production days instead of our overhead garage doors. They are retractable overhead doors, they just happen to be screens and run right along parallel tracks of the solid doors. On weekends when we are not in production and have the solid doors down temperatures reach to ranges of 120F. So we wrote a risk assessment stating that the screens are absolutely necessary for ventilation and internal temperatures. That passes the SQF audit every year. Our auditors have never told us to get rid of them or find a different solution.
