b.
Hot water mechanical operations by being cycled through equipment
that is set up as specified under Section 4-2.3 and 4-2.16 and 4-2.17 and
achieving a utensil surface temperature of 160OF (71oC) as measured by an
irreversible registering temperature indicator; or
c.
Chemical manual or mechanical operations, including the
application of sanitizing chemicals by immersion, manual swabbing,
brushing, or pressure spraying methods, using a solution as specified under
Section 4-4.1 by providing:
(1) An exposure time of at least 10 seconds for a
chlorine solution,
(2) An exposure time of at least 30 seconds for other
chemical sanitizer solutions, or
(3) An exposure time used in relationship with a
combination of temperature, concentration, and pH that yields sanitization
as defined in this Chapter.

Table 1-6 indicates the amount (in ounces) of chlorine compound requried
for initial concentration of 200 ppm free available chlorine(FAC) and the
amount (in ounces) of iodine-type disinfectant required for an initial
dilution of 25 ppm.  Always follow directions on the container label.
a. Table 1-6 is a guide to determine the proper amount of sanitizing
solution for each amount of water. For specific guidelines follow the
manufacturers' recommendation.
