What is the required rinse water temperature for commercial dishwashing machines that rely on hot water for sanitizing as per Illinois Plumbing Code?

  1. 140 degrees Fahrenheit

  2. 160 degrees Fahrenheit

  3. 180 degrees Fahrenheit

  4. 200 degrees Fahrenheit

The correct answer is: 180 degrees Fahrenheit

The required rinse water temperature for commercial dishwashing machines that rely on hot water for sanitizing as per the Illinois Plumbing Code is 180 degrees Fahrenheit (C). This temperature is necessary to ensure that the dishes are properly sanitized and free from harmful bacteria. Water at this temperature is effective in killing bacteria and other contaminants, making it a crucial requirement for commercial dishwashing operations to maintain high levels of cleanliness and food safety standards. Options A, B, and D are incorrect because they do not meet the specific temperature requirement set by the Illinois Plumbing Code for commercial dishwashing machines. Water temperatures below 180 degrees Fahrenheit may not provide sufficient sanitization, leading to potential health risks related to improperly cleaned dishes.
