OBJECTIVES

Chick-fil-A store owners required a disinfection system that met the following objectives:

• Rapid and effective treatment against commonly spread pathogens including SARS-CoV-2

• Safe solution that does not hinder or negatively affect staff, patrons, food, business operation, and facility infrastructure

• Scientifically proven efficacy

• Does not require the hiring of additional staff

• Preferred: Additional benefits including remediation of mold, pollutants, and VOCs

​

SOLUTIONS

Kitchens, dining areas, and play areas were outfitted with two-in-one hybrid UVC disinfection fixtures which provide tri-level air purification during times of occupancy and are scheduled for deep whole-room disinfection treatments at night while restaurants are vacant. Restrooms are treated with automatic between-use fixtures that provide 5-minute treatments while restrooms are unoccupied.
 

ACHIEVED GOALS

Significant Reduction of Pathogens

99.99% and greater rates of reduction of many viruses, bacteria, and mold achieved. See next page for details.

​

Between-Use Restroom Disinfection

Improved disinfection of nexus for pathogen spread without requiring the onboarding of additional staff or extended restroom closures.

​

Improved Indoor Air Quality (IAQ)

Up to 99.99% reduction of allergens, odors, airborne irritants, harmful VOCs generated from cooking apparatus, among others.

​

Effective Treatments During Occupancy

Significant improvements to quality of occupancy achieved for patrons and employees without hindering normal restaurant operation.

​

NEXT STEP

In phase two of the pilot program, UVC disinfection systems at both restaurants will be outfitted with remote monitoring capabilities including live system status, real-time data, extensive reporting, multi-facility operation, central system program adjustments, and automated health pings. The incorporation of remote monitoring maximizes the long-term viability and future-readiness of this system for safe and effective disinfection of pathogens, VOCs, mold, allergens, and beyond.

​

GENERAL RESTAURANT TREATMENT VIA HYBRID DISINFECTION

General areas in restaurants including kitchen, dining area, and play areas are equipped with hybrid UVC disinfection fixtures with two modes of treatment: air purification during working hours and comprehensive whole-room treatment automatically deployed.

​

COMPREHENSIVE WHOLE ROOM TREATMENTS

Devices are schedule to operate for 30-minute comprehensive surface and air treatments evenings from 3:00 -3:30am while premises are vacated. The average dosage of 253.7nm UVC light achieved per treatment is 26.7mJ/cm2 which provides the following rates of disinfection:

SARS-CoV-2: > 99.99%

Influenza: > 99.99%
Coxsackievirus: > 99.9%
MRSA: > 99.9%
C. Dif: > 99%
E. Coli: > 99.99%
Norovirus:> 99.9%
StreptococcusPyogenes: > 99.99%
Penicillium: > 95%
Clostridium Botulinum: > 99.9%

Note: Due to slow replication rate of molds, accumulated dosages over two-week period of nightly comprehensive treatments provide 99% and greater disinfection rates against difficult-to-treat molds including Aspergillus and Fischeralla strains.

​

AIR PURIFICATION

During working hours, air is purified via three stages of treatment including high-intensity UVC, HEPA, and active carbon filtration. In combination, 99.9% and greater reductions of particulates down to .3 microns, viruses, and bacteria can be achieved. Reported indoor air quality improvements include the reduction of the following: Volatile Organic Compounds (VOCs), Odors, Allergens Including Mold Spores and Pollen, Viruses, Bacteria, Pollutants, Smoke, Chemical Vapors, Dust, Lint, and Ozone.

​

RESTROOM TREATMENT VIA AUTOMATED BETWEEN-USE DISINFECTION

Restroom devices are set to automatically engage 5-minute treatments between usage. In-fixture sensors deactivate treatments if occupancy is detected resulting in a safe and effective disinfection solution that requires highly limited engagement from Chick-fil-A personnel.

The dosage of each treatment averages 5.76 mJ/cm2 which provides 99% and greater disinfection against SARS-Cov-2, influenza strains, E.Coli, Streptococcus Pyogenes, among other common restroom pathogens. Due to the frequent use of these restrooms, 15+ treatments can be expected daily. As such, overall daily UVC dosages in restrooms are equivalent to or greater than the aforementioned values for nightly Whole Room hybrid treatments.
