The toilet-room doors are tight-fitting and self-closing. i. The toilet rooms are kept clean and in good repair. j. A supply of toilet paper is available in the toilet rooms. k. At least 5-foot-candle illumination (nat- ural or artificial) is provided in toilet rooms; and toilet rooms are ventilated by a direct opening to the outer air, or by a mechanical ventilating system. (Exhaust fans, if used, should have a minimum capacity of 2 cubic feet a minute per square foot of floor area.) Air vents should be screened or have self- closing louvers. ]. Conveniently located, separate toilets are provided for each sex, excepting that separate facilities need not be required when family shucking is carried on and satisfac- tory toilets are located nearby, or when the plant has fewer than 10 employees. The number of water closets provided complies with applicable State laws. In the absence of such laws, the following number of water closets should be provided: Number of water closets } Number of employees Male Female LO Dita eee ee oe hh eee eee 1 1 LO to:24 nae: oes age ae ee ve 2 2b tO 49 [oe ee a ee eee 3 3 5O'to) 14 a ae ee ee 4 4 1B.tov 10042 ee eee eee 25 25 1 Wherever urinals are provided, one water closet less than the number specified may be provided for each urinal installed, except that the number of water closets in such cases should not be reduced to less than two-thirds of the minimum specified. A 24-inch trough will be considered equivalent to 1 urinal. 2 One additional fixture for every 30 employees over the first 100. m. No drainpipes or wastepipes are lo- cated over food processing or storage areas, or over areas in which containers or utensils are stored or washed. 11. Sewage Disposal.—Sewage shall be dis- charged into public sewers wherever pos- sible. Where private sewage-disposal sys- tems must be utilized, they shall be constructed according to State and local re- quirements; provided, that privies shall be acceptable only where water-carriage systems are not feasible. All newly constructed in- dividual water-carriage systems shall be at least equal to the recommendations contained in the “Manual of Septic Tank Practice,” Public Health Service Publication No. 256.5 All sewage-disposal facilities shall be so con- structed and maintained that waste will be inaccessible to flies and rodents. Public-health reason.—The organisms causing typhoid fever, para-typhoid fever, and dysentery may be present in the body discharges of cases or carriers. When sew- age-disposal facilities are of a satisfactory type, there is less possibility that the shell- fish being processed may become contami- nated with fecal material carried by flies or rodents. Nonwater-carriage sewage-disposal sys- tems should be of a sanitary type, so that excreta are not accessible to flies or rodents. Satisfactory compliance.—This item will be satisfied when: a. Sewage is discharged into public sewers wherever possible. b. Any private sewage-disposal facilities utilized are constructed and operated so as to comply with State and local requirements and privies are accepted only where water- carriage systems are infeasible. Any newly constructed individual water-carriage sys- tems are at least equal to the recommenda- tions contained in the ‘‘Manual of Septic Tank Practice,” Public Health Service Publication No. 256. c. No human excreta are accessible to flies or rodents. 12. Rodent Control.—Shellfish-processing plants shall be free from rodents. ° This publication is obtainable from the Superintendent of Documents, U. S.
