School Safe

1. Improved Hygiene for your School System Using Physics and Chemistry to Improve Indoor Air and surface hygiene. School Safe Protecting our children and our community

2. Agenda for School Safe (Proactive Program for IC and IAQ) Identify the Problems Create IAQ and infection control solutions Develop a monitoring tools for the staff to ensure system works Develop cost / benefit data Phase 1 Phase 2 Phase 3 Phase 4

3. Indoor Air Quality (IAQ)(cost of doing business) • Professor Vivian Loftness University Professor at Carnegie Mellon School of Architecture studied the cost of dirty air: • Annual direct cost of building per employee is $745 • Identifies the cost for Presenteeism. At work but out of it. • Average employee lost work time due to building-related health conditions 8.97 days per employee • Super Emitters???

4. Why schools are the perfect for flu transmission • Super-emitters Flu infected children can, with their immature immune systems, become “super-emitters” and Wake Forest’s Dr. Walter Bischoff discovered that an 8yr old super-emitter spewed out 20,000 RNA copies = 200 capable of infecting 60+ classmates. • Dry environments Many schools can have 15-25% relative humidity levels indoors! This is the PERFECT environment for airborne Viral transmission and contagion. • Low MERV Filter Ratings Many schools have low MERV rated filters like MERV 4-6. You need a MERV 16 or higher to have any real effect on airborne viral capture. • No Ultraviolet Lights Few schools in the US use ultraviolet lights. Schools with UV lights have enjoyed lower airborne viral transmission rates and higher indoor air quality. • Bathrooms with ceiling exhaust fans Most bathroom designs do not incorporate floor level exhaust vents.

5. Schools are the key place for passing bugs in our communities • In schools, the combination of low humidity, super-emitter children and toilet flush aerosolization are a toxic combination. • Low humidity ensures that airborne viruses will stay aloft and travel throughout the school. • Super-emitter children continuously add airborne viruses into the air through breathing, coughing and sneezing, and add even more with every toilet flush.

6. Leading virologists Peter Wright1, Gabrielle Neumann2and Yoshihiro Kawaoka3state that flu epidemics start in schools 1. Professor Pediatrics, Pathology, Microbiology and Immunology Chief, Division of Pediatric Infectious Diseases Vanderbilt University School of Medicine 2. Associate Professor Department of Pathobiological Sciences School of Veterinary Medicine University of Wisconsin 3. Professor Department of Microbiology and Immunology University of Tokyo 4. Field Virology 2007 Fifth Edition Page 1705 Virologists Peter Wright state: “Increases in school absenteeism mark the beginning of a new epidemic, suggesting that school-age children play a critical role in disseminating influenza viruses. Increases in school absenteeism are typically followed by increases in work absenteeism.4” Since flu infected children can, with their immature immune systems, become “super-emitters”, they easily infect their classmates as they all intermingle while traveling from classroom to bathroom to gym to lunchroom all the while super-emitters are spewing out infectious flu viruses. Schools now have many good reasons to take a vested interest in advocating for clean and properly humidified air in the school especially in the dry wintertime.

7. Methods of Transmission • Airborne • Direct contact (Hands) • Fomites (Contaminated Surfaces)

8. SparGuard • Safe product no toxicity after it is applied (water based molecule) • A Silicone Quaternary Ammonium Salt • EPA label • Works on all surfaces • 90 Day efficacy • Effective against mold, fungus, algae and microbes. Additional testing not EPA validated shows efficacy against the flu virus*

9. Sanders Filters • Easy to use. Limited training required. Air filtration configured to meet customers needs. • Scalable Solutions: Capable of working on fans and high end HVAC systems • Protects capital investments, employees and livestock from bio-aerosols • Dramatically changes air quality: captures all particle sizes from submicron size and up • Can be configured to capture gases / VOC’s

10. Unique Hand Sanitizer • PureChem manufactures a series of FDA compliant hand sanitizers • PureChem has the ability to make hand sanitizers with residual capacity for protection • Provides a low cost manufacturing facility that can provide world class commodity products • Studies show HAI reductions from 20 to 40 % using SparGuard technology

11. Other school related health concerns • Asthma 10% of the total population. In families of color the asthma rate is higher • Severe allergies 20% of the total population. • MRSA • Athletes foot / ringworm • Food borne disease

12. Cost Benefit Analysis of School Safe Containment Filters SparGuard Reduce possibility for fomite contamination Expect reductions in absenteeism for staff and students (21% reduction in HAIs in 22 month Turkish study) Reduces cleaning time Allows for cost savings in cleaning supplies • Saves on cleaning costs (labor) • Will also reduce absenteeism for staff faculty and students with asthma and allergies • Improves life of the HVAC units • Dramatically improves IAQ for the school system Sick leave savings / substitute teacher savings
