Cleaning and Disinfection Protocol

Issued July 17, 2020; Revised October 28, 2020​

1.0 PURPOSE

In order to protect Albemarle County Public Schools (ACPS) staff, students and teachers from the COVID-19 virus, the division will enhance the cleaning and disinfection protocols in accordance with nationally recognized guidance documents. ACPS is utilizing guidance from the Centers for Disease Control and Prevention’s (CDC) Reopening Guidance for Cleaning and Disinfecting Public Spaces, Workplaces, Businesses, Schools, and Homes, and CDC’s Guidance for Cleaning and Disinfecting.

2.0 RESPONSIBILITY

The Building Services Department cleans and maintains ACPS facilities. During the school day, non-custodial staff members will be needed to help continually disinfect high-touch surfaces. The shared disinfection responsibilities for learning spaces, technology equipment, and buses is outlined in Section 4.

3.0 DEFINITIONS

ACPS: Albemarle County Public Schools
ATP: Adenosine triphosphate
CDC: Centers for Disease Control and Prevention
COVID-19: Coronavirus Disease 2019
EPA: Environmental Protection Agency
HMIS: Hazardous Materials Identification System
HOCl: Hypochlorous acid
PPE: Personal protective equipment
VDH: Virginia Department of Health

4.0 PROCEDURES

Providing clean and safe buildings and buses for students and staff members is a top priority for ACPS. ACPS has added enhanced disinfection measures to existing procedures in response to COVID-19. The addition of CDC’s recommended measures coupled with existing industry cleaning standards provides ACPS with a robust school cleaning and disinfection program that will accommodate any school attendance scenario.

A. Enhanced Cleaning and Disinfection Protocols

Based on the guidance provided by the CDC, the following best practices and cleaning/disinfecting measures are part of day and evening custodial responsibilities:

  • Wearing appropriate PPE while cleaning
  • Wearing of face covering while in the school facility
  • Increasing the disinfection of high frequency touch points
  • Using disinfectants on EPA’s List N: Disinfectants for Use Against SARS-CoV-2 (COVID-19)
  • Using new disinfecting technologies
  • Additional training for all custodial staff

Disinfectants are used in strict compliance with manufacturer specifications. Safety data sheets for chemicals used in this protocol are linked in Section 4(D).

ACPS cleans and disinfects for health by following a prescribed frequency of task. The routine cleaning and disinfecting are performed by custodial staff on a daily basis with special focus on high-touch areas that includes, but is not limited to desks, chairs, interior/exterior door handles, sink handles, bottle fillers, dispensers, handrails, countertops, and doors. Restrooms are thoroughly disinfected nightly as well as throughout the day. Custodians clean surfaces to remove dirt and debris before disinfecting surfaces. Custodial staff use a general cleaner, a quaternary ammonium disinfectant or a hypochlorous acid (HOCI) disinfectant. The hypochlorous acid disinfectant has a Hazardous Materials Identification System (HMIS) minimal hazard rating for health, flammability, physical and reactivity.

Each classroom/teaching space, teacher lounge, staff restroom will receive hypochlorous acid disinfectant wipes that are safe to use without gloves. Students can assist with using the disinfectant wipes for their personal spaces.

Quality control measures will be reinforced by consistent inspections for cleanliness, custodial training, and by using an adenosine triphosphate (ATP) meter. This device is an instrument to detect the amount of organic matter that remains after cleaning an environmental surface in order to continually evaluate the effectiveness of cleaning protocol. ATP systems do not detect viruses directly. However, COVID-19 infected material that contains biological residues will be detected by an ATP system.

Table 1 highlights the areas for disinfection, methods, and responsible parties.

Table 1. Disinfection Areas, Products and Responsible Parties

​Disinfection Area ​Frequency ​Responsible Group ​Products/Resources
Learning Spaces (Classrooms):

B. School Re-entry Enhanced Cleaning Protocols

ACPS has required additional training for all custodial staff. Training topics include, but are not limited to:

  • Proper use of PPE such as gloves, face masks, and goggles
  • Proper use of all disinfectants (mixing ratios, chemical interactions, dwell time)
  • Proper use of disinfecting misters
  • Proper training and documentation on all applicable Occupational Safety and Health Administration (OSHA) regulations/requirements.

ACPS is utilizing new technologies to assist in the disinfection of ACPS facilities. Disinfectant misters produce a fine consistent mist that allows for surface disinfecting. Disinfectant misters may be used in the disinfection of building areas, with a focus on restrooms and clinic areas. The disinfectant misters spray the Annihilyte disinfectant linked in Section 4(D).

High-touch areas within the school buildings receive extra attention by custodial staff throughout the building and teachers in learning spaces.

Handwashing signage has been placed throughout each school building to encourage students and school personnel in this effort. Hand sanitizer stations have been added to various locations within each school. All hand sanitizer will meet the CDC requirements for alcohol content. All classrooms will be provided disinfectant wipes for teachers to assist in the disinfection of student work stations.
