Hello Aazk.

We are a group of students from Denmark, Europe. We are studying Occupational Therapy and right now we are working on an assignment in a Danish Zoo, with focus on work environment. 
We have observed several difficulties containing the Zoo keepers working postures during their cleaning of the Tiger and Lion cages. The cages have a wooden floor and tiles on the walls - the Zoo keepers use a broom for scrubbing these with. This working posture takes a lot of physical effort and is not healthy in the long run. We would like hear you, as an association, if you have any experience and suggestions to which these difficulties could be met and maybe solved. Furthermore if you have any materials that you think would be appropriate.

We will appreciate your answer and time. 
We are looking forward to hearing from you. 

With regards from Sandie, Nanna, Maria & Christoffer,  The Occupational Therapy School UCN.
