How Facilities Have Been Adjusted
- Rooms have been stripped of excess furniture to allow more space for social distancing requirements
- Rooms have been cleaned thoroughly
- Shields have been installed in some areas
- Hard-to-Sanitize Areas will not be available for use.
- Students will be encouraged to use one-way passing routes
Building Cleaning Routines and Plans:
Between School Days:
Every classroom cleaned with disinfectant spray between each school day using victory disinfectant sprayers (backpack/ handheld)
- with Victory sprayer with Biox cleaner/Bioesque Botanical disinfectant and or with
- Alpha HP disinfectant – ALL walls, desks, chairs, tables, etc. – door handles after heavy traffic (recess, lunch, etc) – (Teacher training)
- Bathrooms and “Often Touched Surfaces”– after school and at 10:00 a.m. and 12:45 p.m. daily
- Lunchroom – Cafeteria serving tables for grades 6-12 will be disinfected between uses with Victory sprayer Biox or Alpha HP?
- Ventilation – See AHC-CDC Ventilation below (August 6, 2020 Meeting with Dave’s Heating to address needs for ventilation)
Solution Fact Sheets:
- Biox – Bioesque Botanical disinfectant/ Fact Sheet https://benefect.com/pdf/disinfectant-sds-benefect.pdf
- Alpha HP disinfectant/ Fact Sheet https://content.oppictures.com/Master_Images/Master_PDF_Files/DVO5549254_SDS.PDF
Facilities: Use and required practices
- Close playground equipment until more guidance is given by the DOH.
- NO after school activities – NO public activities
- Desks 6’ apart all around
- Bathrooms one at a time
Ventilation: CSD Maintenance Director meeting with representatives of Dave’s Heating on August 6, 2020
- Consider taking steps to improve ventilation in the building, in consultation with an HVAC professional, based on local environmental conditions (temperature/humidity) and ongoing community transmissions in the area:
- Increase the percentage of outdoor air, (e.g. using economizer modes of HVAC operations) potentially as high as 100% (first verify compatibility with HVAC system capabilities for both temperature and humidity control as well as compatibility with outdoor/indoor air quality considerations).
- Increase total airflow supply to occupied spaces, if possible.
- Disable demand-control ventilation (DCV) controls that reduce air supply based on temperature or occupancy.
- Consider using natural ventilation (i.e., opening windows if possible and safe to do so) to increase outdoor air dilution of indoor air when environmental conditions and building requirements allow.
- Improve central air filtrations:
- Increase air filtrations to as high as possible without significantly diminishing design airflow.
- Inspect filter housing and racks to ensure appropriate filter fit and check for ways to minimize filter bypass.
- Consider running the HVAC system at maximum outside airflow for 2 hours before and after occupied times, in accordance with industry standards.
- Generate clean-to-less-clean air movements by re-evaluating the positioning of supply and exhaust air diffusers and/or dampers and adjusting zone supply and exhaust flow rates to establish measurable pressure differentials. Have staff work in “clean” ventilation zones that do not include higher-risk areas such as visitor reception or exercise facilities (if open).
- Consider using portable high-efficiency particulate air (HEPA) fan/filtration systems to help enhance air cleaning, especially in higher-risk areas.
- Ensure exhaust fans in restroom facilities are functional and operating at full capacity when the building is occupied.
- Consider using ultraviolet germicidal irradiation (UVG) as a supplemental technique to inactivate potential airborne virus in the upper-room air of common occupied spaces, in accordance with industry guidelines.
