We operate a number of small cold rooms at -35 / 40. Due to the frequency of use and other issues there are substantial problems with these rooms icing up, creating an 'ice-rink' effect. Can any one point me in the direction of some good guidance on how the risk may be minimised as staff have to transfer large trolleys in and out of these stores. Information such as suitable floor specifications, footware specifications etc would be most helpful. We are a pharmacutical company and these are in 'clean' production areas so any suggestions must be 'GMP'(good manaufacturing practice) compliant.
Many thanks
Deana

Though I have no experience of commercial cold rooms, your problem suggests to me that you must be allowing a lot of moist, outside air to enter the rooms. Apart from the icing problem, you may be reducing the efficiency of the units and using more power to run them than you need to.
On the basis that prevention is better than cure, have you looked at installing additional barriers, eg clear plastic strip curtains, or other measures either inside or outside the coldroom doors to reduce mixing of inside and outside air when the coldroom doors are open?

Deana,
If you require anti-slip footwear I can recommend some called "Shoes For Crews" - I found them excellent for all our industrial surfaces, and the attendants at the local swimming pool use them. Give me an email if you need contact details etc.
Hope this helps

Deana,
It sounds like you are experiencing the freezing of condensation caused by warm air entering the freezer when the door is opened. The solution to this may be to put an extra set of strip curtains in the doorway or even automated sensor operated secondary doors that close after something has passed through them in to the freezer.

Deana,
As has already been said, the ice would seem to be from unwanted mositure.
This moisture could be from outside air, poorly clad pipework dripping or even from a units de-frost cycle, is there a sytem to catch the water from the fans/condensors etc during de-frost
Whatever it is your engineer/fridge installer should be able to solve this one.
Regards
Andrew
