1. Mintie Technologies, Inc. ECU Product Introduction and Demo/Training Virginia Presentation

2. Environmental Containment Unit (ECU) ™ The ECU ™ is the only clinically tested, collapsible and portable containment product that enables a range of applications with the appropriate level of HEPA-filtered negative air pressure required by the CDC.

3. Environmental Containment Unit (ECU) ™ ECU Ceiling Cavity ™ Ceiling cavity projects: cabling, repairs, re-lamping, firewall penetration, inspections ECU AnteRoom ™ Wall access projects, repairs Anteroom for construction areas Anteroom for airborne infection isolation

4. ECU-AnteRoom ™ Construction and Maintenance Wall access projects Anteroom for construction areas Bio-Security Anteroom for airborne infection isolation

5. ECU-AnteRoom ™ Product Benefits ECU-AR ™ is first collapsible, portable anteroom—no more manual setups Innovative design features Multiple uses – lowers cost of ownership Clinically tested by Andrew Streifel Satisfies HRSA requirements for hospital “surge capacity”

6. The HRSA Mission HRSA Priority Area: isolation surge capacity  Upgrade or maintain airborne infection disease isolation capacity to have at least one negative pressure, HEPA- filtered isolation facility Any solution must safely protect: 1. Patient 2. Caregiver 3. General patient and visitor population

7. Short-term Airborne Infection Isolation: 4 Possible Solution Methods Build new isolation rooms – EXPENSIVE Convert existing room ventilation systems to isolation systems – EXPENSIVE Maintain current isolation rooms– AFFORDABLE Create short-term isolation room with portable anteroom–AFFORDABLE

8. CDC on Airborne Infection Isolation Use airborne infection isolation rooms for persons with diagnosed or suspected airborne infectious diseases: 1.“Create isolation room, preferably with an anteroom, to reduce exposure to aerosolized infectious particulates….” 2.“If anteroom is not available, use portable, industrial-grade HEPA filters in patient room to enhance filtration of infectious particulates….”

9. Short-term Airborne Infectious Isolation ECU-AnteRoom ™ for BT or SARS Simultaneously protects patient, caregiver and general patient population Anteroom method is preferred by CDC Rapid, safe conversion—typically operational in minutes Can be deployed to any area within hospital or distributed throughout region Visible protection reassures patients, caregivers and visitors

11. Block off return air vent – air scrubber may not capture all IDN No change from equal pressure, or if return is blocked off, room goes positive to surrounding space Pressure differential in room does not change (no air exhausted to outside or other space) Monitoring of room required by CDC once per day when in use Short-Term Isolation: HEPA Air Scrubber

12. Short-Term Isolation: ECU-AnteRoom ™ Negative pressure (greater exhaust than supply air volume) Return air vent blocked off from central air handler Exhaust air is through ECU-AnteRoom™ HEPA- filtered negative air machine (Permitted by CDC)

13. Short-Term Isolation: ECU-AnteRoom ™ 6 air exchanges per hour for existing rooms (between 150-250 cfm for cooling) Pressure differential of 0.01 in wg Greater than 125 cfm air-flow differential Sealing of room walls for air leakage not required Monitoring of room required by CDC once per day when in use

14. ECU-Ceiling Cavity ™ Product Benefits No more manual setups! Operational in 15 minutes one person Portable and collapsible Compact: stores easily Design ensures integrity of containment Clinically tested by Andrew Streifel Negative air capabilities Preferred method

15. Key ECU Drivers HRSA mandate has motivated states CDC has motivated Infection Control –ECU ™ creates immediate compliance –Infection Control lowers risk and drives Facilities ECU ™ is best containment solution available –Flexibility and reliability; long-term cost savings ECU-AnteRoom ™ is the only portable anteroom product on market Increasing demand for surge capacity

16. ECU-AnteRoom ™ for Airborne Infectious Isolation Frequently Asked Questions

17. Is it safe to recirculate HEPA-filtered air back into the hospital? YES! “Direct exhaust air to the outside, away from air-intake and populated areas. If this is not practical, air from the room can be recirculated after passing through a HEPA filter.” Category 1C “Guidelines for Environmental Infection Control” Morbidity and Mortality weekly Report, June 6, 2003 Pg. 12, Sec. IV.A.5

18. Is it safe to recirculate HEPA-filtered air back into the hospital? YES! HEPA filters capture 99.97% of all airborne particulates—including bacteria and mold spores HEPA filtered air is of same quality as that used in bone marrow transplant rooms, cardiac and orthopedic operating rooms for immunocompromised patients Typical hospital corridor is filtered at 80% efficiency; less than that being discharged from HEPA filtered NAM

19. Will corridor become overly pressurized by exhausting HEPA-filtered air into it? NO! Perform an engineering evaluation before blocking off returns and discharging air into other spaces Sheer volume of corridor and associated open spaces addition will not be affected with addition of 400/800/1200 cfm of clean HEPA-filtered air

20. Can ECU-AnteRoom ™ be used to create larger airborne infection isolation areas? YES! With proper engineering evaluation, ECU- AnteRoom ™ can be used for either single room conversions, or conversions of larger areas.
