■ The Challenge Before Installation: Severe Staff Skin Irritation and the Risk of Chemical Residues on Food

To prevent food poisoning, the kitchen at a certain school used massive amounts of bactericides like sodium hypochlorite. However, the kitchen staff, who handled these harsh chemicals daily, suffered from chronic “rough hands" and skin irritation, which had become a serious concern. Furthermore, when sterilizing cutting boards and vegetables, even after rinsing thoroughly with running water, there was a constant lingering fear: “Is the chemical odor still there?" and “Are there any residues left on the food the children will eat?"

⚠️ Serious Concerns Plaguing the Kitchen

  • Deteriorating Work Environment: Severe skin irritation and rough hands among staff caused by strong disinfectants.
  • Food Safety Worries: Fears of chemical residues on ingredients and dishes, and the overwhelming chlorine smell filling the room.
  • Labor Burden: The immense time, effort, and water costs associated with the meticulous “rinsing process" required after chemical disinfection.

■ The Decisive Factor: Zero Residual Toxicity. “Sterilize While Washing" Just by Turning on the Tap

Ozone water was selected as the ultimate solution capable of satisfying both “children’s safety" and “staff health." Ozone (O3) is created from naturally occurring oxygen and water. After its powerful oxidizing force destroys bacteria and viruses, it rapidly reverts to plain “oxygen" and “water." The overwhelming safety of “absolutely zero residual toxicity," combined with the unparalleled convenience of having sterilizing water flow simply by turning on the tap—without the hassle of mixing chemicals—were the decisive factors for its implementation.

■ Post-Installation Results: Skin Conditions Improved, and Zero Rinsing Massively Reduced Work Time!

After installation, the staff rejoiced at the “dramatic improvement in their skin condition." The massive reduction in the use of strong chlorine bleach eliminated skin damage, and the sharp chemical odor unique to the school kitchen completely vanished.

Furthermore, when washing vegetables and other ingredients with ozone water, there are no residues left behind, which means “no subsequent rinsing is required." This significantly cut down daily prep and cleanup times and led to a noticeable reduction in water bills. Additionally, using ozone water to clean the floors and drains has successfully prevented the typical slimy build-up and foul odors.

  • ✅ Elimination of Rough Hands: Created a safe work environment where staff can work with a smile.
  • ✅ Zero Rinsing Time: Removed an entire step from sterilizing cutting boards and ingredients, saving immense time and water.
  • ✅ Contribution to HACCP: Prevented slime and mold throughout the kitchen, eliminating secondary contamination risks.

Frequently Asked Questions from School Kitchens & Facility Managers

No, major construction is not required. Thanks to its compact design, it can be easily retrofitted in tight spaces, such as under the existing sinks or mounted on the wall in the kitchen. Installation can be completed in a short amount of time after operating hours.

Absolutely. Because ozone rapidly reverts to oxygen after destroying bacteria, no chemicals remain on the ingredients. Furthermore, because ozone breaks down ethylene gas, it is highly effective at “preserving the freshness" (extending the shelf life) of vegetables.

The only raw materials required for ozone water are “water" and “air (oxygen)," completely eliminating the continuous cost of purchasing chemical sterilizers. The only running costs are your standard water bill and a minimal amount of electricity, leading to significant cost reductions in the long term.

Yes, it is extremely effective. Ozone possesses powerful oxidizing capabilities second only to fluorine (killing bacteria about 7 times faster than chlorine). It instantly sterilizes and inactivates bacteria and viruses—even those like Norovirus, which are resistant to alcohol—by directly destroying their cell membranes.

AIC Specialist Insights: “Staff Safety" Protects “Food Safety"

While hygiene management under HACCP is crucial, it defeats the purpose if it causes kitchen staff to suffer from skin irritation or fall ill due to chemical fumes. Introducing an ozone water generator—which is “gentle on staff but ruthless on bacteria"—improves the working environment and ultimately serves as the best investment for achieving a higher level of “safe school lunch provision."
