Food Facilities and Pest Control: Handwashing Sinks, Plumbing and IPM
Last checked:
Handwashing sinks must be easy to reach in prep, service and dishwashing areas and in or next to restrooms, and used for nothing else. Drinking water must never connect to a non-drinking water line. Pests are kept out with integrated pest management: deny them access, food and shelter.
What to know for the exam
- Every handwashing sink needs warm water, soap, a way to dry hands and a handwashing sign.
- An air gap or an approved backflow device prevents backflow into the drinking water.
- Galvanized metal must never touch acidic food such as tomato sauce.
- Bug zappers must not hang over food prep areas.
- Restrooms on site need a tight-fitting, self-closing door that is kept closed.
Questions and answers

A physical link between the drinking water system and a non-drinking water source, which can let contaminated water flow back into the supply.
What is integrated pest management?
A program that keeps pests out by denying them access, food and shelter, and uses a licensed pest control operator for treatment.
Can a handwashing sink be used for anything else?
