#5 A refrigerated truck used outside the pharmaceutical cold chain (UMIT)

Dear All,

This space if for you to hunt the situations listed in the first posting. As I did in the posting on Temperature Violation, I am making a new one to showing an example of being more elaborative on the story behind the photograph. When you make your postings, please explain more, don't give just a couple of descriptive phrases what the photo shows. There is always a good story behind every single photograph...

Here we go...

Once in a while, on my way to the office, I stop in this Café Léo in Rive, Geneva to have a cup of tea with lemon. 

Rive is one of the busiest places in Geneva, a hub for many public transport bus lanes and connections as well as for some restaurants and a big shopping hall (with meat and mostly food shops) around. And every morning, many refrigerated trucks make their stops in the circle to offload the daily supplies, mostly vegetables and meat to these restos. 

As  you see in the map above, only within a perimeter of 50 meters, there are 10 locations that require temperature controlled distribution of food items. 

Here I see two refrigerated trucks... The Petit Forestier one parked before, and I watched the driver getting out, opening the back door of the truck, loading his trolley with supplies and going off to drop it to whatever resto. But he left the back door of the truck open. He came several times back for more loads... It took him around 8 minutes to distribute all he had to do with an open back door which exposes the inner space of the truck to heat up. Maybe he finds closing the heavy door each time a bit cumbersome. The thermodynamics of leaving the door open in a refrigerated truck deserves a different level of discussion in our discussion forum. I mean, how the thermodynamics work here and the inner space heats up? Does the cold air inside escapes out from the door, or the warm air enters the truck?

Though this is not a recommended practice, the impact on the products would be minimal and I only stop in this spot to have my lemon tea, which does not require any temperature controlled distribution supplies to have. It is CHF 3.80 which is 4 USD. Well, welcome to Geneva, things are expensive here... 

Wishing you a very good day...
