As Amended
SEC. 75-37-21. Temperature required.
The refrigeration system for a locker plant or branch locker plant shall be equipped with accurate and reliable controls for the automatic maintenance of uniform temperatures as required in the various refrigerated rooms and shall be of adequate capacity to provide under extreme conditions of outside temperatures and under peak load conditions in the normal operations of the plant, the following temperatures in the several rooms, respectively:
(a) Chill room. Temperature of thirty-four (34) degrees above zero (0) fahrenheit plus or minus two (2) degrees with a tolerance of ten (10) degrees fahrenheit for a reasonable time after fresh food is put in for chilling.
(b) Sharp freeze room; sharp freezing compartments. Temperatures of ten (10) degrees below zero (0) fahrenheit or lower or temperatures of zero (0) degrees fahrenheit or lower when forced air circulation is employed with a tolerance of five (5) degrees fahrenheit for either type of installation for a reasonable time after fresh food is put in for freezing.
(c) Locker room. Temperature of not to exceed zero (0) degrees fahrenheit with a tolerance of three (3) degrees fahrenheit higher.
The foregoing temperatures shall not be construed as prohibiting such variations therefrom as may occur during short periods of time incidental to defrosting. For experimental purposes, the board, upon an application in writing, may authorize for a limited and prescribed period, the installation and use of refrigeration systems or methods which in the opinion of the board will result in improvement over present methods.
An accurate direct reading thermometer shall be provided in the chill room and in the sharp freeze room or compartment. An accurate self-registering or self-recording thermometer of a type approved by the board shall be provided in the locker room. The discs or other temperature records of such thermometer shall be kept at the plant and shall be preserved for at least one (1) year from the date of the recording. The thermometer in the locker room shall be placed in a position where it is readily observable by patrons.
