Three Compartment Sink Procedures

Food safety regulations for restaurants are strictly enforced in most cities. Fortunately, the rules are easy to follow.

All you havet to do is wash, rinse, sanitize and air dry your dishes, utnesila and glassware using a sink with 3 basins (compartments).

  1. The first sink basin has hot water (35C/95F) and soap to clean the utensils, dishes & glasses
  2. The second sink basin has hot water to rinse the soap off.
  3. The third sink basin has warm water (25C/75F) and a sanitizer to kill remaining germs.
  4. Step 4 uses a rack to hold the utensils, dishes & glasses for air drying.

You can do this with the following sanitizers: chlorine at 50 or 100ppm, quat at 200ppm or iodine at 25ppm.

Chlorine and quaternary ammonium sanitizers are by far the most important especially in food preparation. The table below lists their pros & cons. Peroxide use is more specialized for things like hot tubs and contact lens cleaners where skin/eye sensitivity can be an issue.


Pros Cons
Effective on a wide variety of bacteria Can be corrosive
Not affected by hard water Can be irritating to the skin
Generally inexpensive Deteriorates over time
  Loses some activity in the presence of organic matter



Pros Cons
Not affected by hard water Effectiveness decreases greatly with increase in pH
Less irritating to the skin than chlorine Should not be used in water > 50°C
Activity is not lost rapidly in the presence of organic matter May also discolor equipment and surfaces


Quaternary Ammonium Compounds (QAC):

Pros Cons
Nontoxic, odorless, colorless, noncorrosive, nonirritating Slower at killing some microorganisms
Relatively stable in the presence of organic matter Not compatible with some detergents
Active over a wide pH range Not compatible with hard water
