Drivers' room.— A room connected with the office should be pro- 

 vided in which drivers can score their books on returning from the 

 routes. Bath and toilet facilities also should be provided for the 

 drivers and men. 



Laboratory. — A laboratory for the bacteriological and chemical 

 examination of milk is essential for all plants. Small plants need

SIZE OF ROOMS. 



Each room in the plant should be large enough to avoid crowding 

 the machinery or workmen, but at the same time there should be no 

 unused space, for that causes extra labor in getting from one piece of 

 apparatus to another. 



There is a wide variation in the size of the various rooms in milk 

 plants, as well as in floor area per 100 gallons of bottled milk handled 

 daily. These variations are due in a large measure to the lack of 

 standardization of milk plants and to the fact that many have been 

 constructed without consideration of important factors bearing on 

 the size of rooms.
