(2) equipment and utensils shall be thoroughly cleaned in the first compartment with a hot detergent-sanitizer solution that is kept clean and at a concentration indicated on the manufacturer's label, and shall be sanitized in the second compartment in hot water in accordance with paragraph (h)(1) of this section or with a solution containing that same detergent-sanitizer in accordance with paragraphs (h)(2)-(5) of this section.

(1) immersion for at least ½ minute in clean, hot water of a temperature of 170°F (congruent to 77°C) or greater;

(2) immersion for at least one minute in a clean solution containing 50 parts per million of available chlorine as a hypochlorite and having a temperature of at least 75°F (congruent to 24°C) or greater;

(3) immersion for at least one minute in a clean solution containing 12.5 parts per million of available iodine, having a pH range which the manufacturer has demonstrated to be effective and a temperature of at least 75°F (congruent to 24°C) or greater;

(4) immersion for at least one minute in a clean solution containing 200 parts per million in a quaternary ammonium compound and having a temperature of 75°F (congruent to 24°C) or greater. The quaternary ammonium compound used shall have been compounded by the manufacturer to assure effectiveness in waters up to 500 parts per million hardness at use concentration;

(5) immersion in a clean solution containing any other chemical sanitizing agent allowed under title 21 of the Code of Federal Regulations, section 178.1010, (revised as of April 1, 2013), pages 362-371, published by the Office of the Federal Register and available from the Superintendent of Documents, U.S. Government Printing Office, Washington, DC 20402, that will provide the equivalent bactericidal effect of a solution containing at least 50 parts per million of available chlorine as a hypochlorite at a temperature of 75°F (congruent to 24°C) or greater for one minute;

(6) treatment with steam, free from materials or additives other than those specified in title 21 of the Code of Federal Regulations, section 173.310, (revised as of April 1, 2013), pages 140-142, published by the Office of Federal Register and available from the Superintendent of Documents, U.S. Government Printing Office, Washington, DC 20402, in the case of equipment too large to sanitize by immersion, but in which steam can be confined; or

(7) rinsing, spraying, or swabbing with a chemical sanitizing solution of at least twice the strength required for that particular sanitizing solution under paragraphs (2), (3) and (5) of this subdivision in the case of equipment too large to sanitize by immersion.

(1) an integral heating device or fixture installed in, on or under the sanitizing compartment of the sink capable of maintaining the water at a temperature of 170°F (congruent to 77°C) or greater;

(2) a numerically scaled indicating thermometer, accurate to plus or minus 3°F (congruent to plus or minus 1°C) convenient to the sink for frequent checks of water temperature; and

(3) utensil racks or baskets of such size and design to permit complete immersion of utensils and equipment in the hot water.
