photocopier / printer stored outside chemical store room

Photocopier / printer stored outside chemical store room: Hi I have just come back off holidays to find a large photocopying machine placed opposite the door to my Chemical Store room—within a metre. This photocopier / printer is for all staff to use. Are there any regulations stating this is not permitted? I dont feel comfortable having the machine in its present position, but I have been told there is nothing to worry about.
