PHYSICAL PLANT 



BUILDINGS 



The foundation of a sanitation program for any industry neces- 

 sarily begins with a discussion of the physical plant. Regardless 

 of the excellence of the starting raw material the final product 

 invariably reflects the hygienic conditions under which it was 

 processed. The design, layout, and construction of the physical 

 plant play an important role in assuring the production of a safe, 

 clean, and wholesome product. The reader should not think of the 

 physical plant in a limited context confined merely to the construc- 

 tion of plant buildings. Rather, it is suggested that the physical plant 

 be defined as all structural components germane to the processing 

 operation. Such a definition would include not only the building, but 

 also other facilities such as plumbing, waste disposal systems, 

 water supply, storage areas, and processing and refrigeration 

 equipment. 



The plant buildings must be soundly constructed and always in 

 good repair. All outside openings should be adequately screened to 

 prevent the entrance of flies, birds, rodents, and other pests. All 

 screen doors should be self-closing and operable. In addition to
