(B) Hand sink size should be no smaller than 30 cm. (12 in.) length X 30 cm. (12 in.) width X 15cm. (6 in.) depth with a 30 cm. (12 in.) clearance above the sink.
(C) Hand sink mixing valve should be a minimum of 4 in. (10 cm.) above the flood rim of the sink, and extend a minimum of 10 cm. (4 in.) from the back inside bowl to allow room for proper hand washing.
(D) Hand sink should be a minimum of 80 cm. (32 in.) above the floor. Some government jurisdictions may require a higher distance in restrooms for handicapped persons.
(E) Hand sinks should have a stainless steel splashguard attached if splash from the sink
can contaminate adjoining food preparation, food contact surfaces and/or utensil drying area surfaces (drainboards).
(F) A minimum of two hand wash sinks will be required in restaurants for the following reasons:
a. Because handwashing is such an important intervention in the control of foodborne illness, sufficient handwashing sinks must be available to make handwashing not only possible, but likely to occur at all appropriate times and places.
b. Green, et al (Journal of Food Protection, March 2007) found that handwashing was more likely to occur in restaurants whose food workers received food safety training, had more than one handwashing sink, and had a handwashing sink in the observed worker's sight.
c. Multiple hand sinks ensure employees will have a hand sink close by which will encourage hand washing.
d. If multiple people need to wash hands at same time there are multiple locations to do so.
e. If one sink becomes inoperable there is a second available.
f. When hand sinks are properly located, they will be easily and readily accessible to employees who are preparing food, dispensing food, and conducting warewashing operations.
