Classroom Disinfection with Ultraviolet Light 5

The UV Solution: Classroom Disinfection with Ultraviolet Light

Today, schools face the significant challenge of providing all children with a quality education from kindergarten through twelfth grade. School administrators must also ensure a safe and engaging classroom while complying with the new health standards that prevent the spreading of infectious diseases.

Typically, a classroom requires adequate ventilation, air filtering, cleaning (physically removing dirt, germs, etc.), and disinfecting (killing germs) to guarantee a pathogen-free indoor environment that will help protect the health of the students and teachers.

Ventilation, through open doors, windows, vents, and fans, brings fresh, outdoor air into a classroom which helps keep pathogens from accumulating inside the space and infecting the students and teachers. Filtering air through the HVAC system can remove pollutants and pathogens.

Traditionally, teachers used detergent to clean and chemicals to kill the germs on classroom surfaces. However, neither method protects the students and faculty from airborne pathogens. In addition, chemical disinfectants can cause allergy or asthma symptoms, breathing difficulties, skin burns, and eye damage.

UVC light for Classroom Disinfection - An Alternative to Chemicals

Ultraviolet light 254 nm goes by several names:

  • Ultraviolet-C (UVC) 254 nm

  • Germicidal Ultraviolet (GUV)

  • Ultraviolet Germicidal Irradiation (UVGI),

UVC light for classrooms provides a safe, disinfecting option for destroying the genetic material (DNA and RNA) in viruses, bacteria, and mold in the classroom's air, on surfaces, and even the students and teachers as they enter the classrooms.

Environmentally-friendly UVC lights do not produce ozone or other harmful volatile organic compounds (VOC).

Types of UVC Lights for Disinfecting Classrooms

Manufactures offer three basic types of UV light sanitizer for classrooms that target different areas of a room:

  • Air Handler Units (AHU) and duct fixtures, like the Lumalier AR Series UVC, are installed inside a ventilation system to disinfect airborne pathogens.

  • Upper-Air UVC fixtures target high-risk areas, like ceiling areas.

  • Fixed and portable surface disinfection UV fixtures are used to disinfect contaminated surfaces of a classroom.

Five Benefits of Disinfecting and Cleaning Classrooms

Disinfecting and cleaning classrooms to protect against dangerous microbes can boost students and faculty's productivity and morale, and will also work to keep them healthy. It can also help maintain the school's equipment.

1. Decreases Absenteeism and Sickness

A lack of disinfecting and cleanliness in a classroom can increase respiratory illness due to bacteria, viruses, and allergens by 50 to 370 percent, particularly in spaces with low ventilation rates. Fortunately, systematic disinfecting of classroom surfaces can decrease absenteeism during the peak flu season by 53 percent.

2. Improves Academic Success

According to a study by the Center for Facilities Research at APPA (an association promoting leadership in educational facilities), when exposed to clean and disinfected environments, students achieve higher grades and graduation rates than in less maintained or clean schools.

3. Contributes to Classroom Continuity

Clean and disinfected classrooms can minimize teacher sick days, and contribute to classroom continuity and student success.

4. Promotes Productive Teaching

Disinfecting classrooms creates a clean work environment which can boost teacher morale and improve productivity, because instead of spending their time before and after class cleaning and disinfecting their classrooms, they can plan lessons and grade homework.

5. Helps Maintain Equipment Durability and Function

A clean classroom helps protect equipment from dust and dirt that can damage equipment performance and longevity. In addition, cleanliness promotes the efficient performance of HVAC equipment, with less maintenance.

Lumalier UVC Lights for Classroom Disinfection

For over 60 years, Lumalier's advanced UV Germicidal Disinfection products have provided schools with UV lights in classrooms - a science-based approach to safe classroom disinfection that improves indoor air quality, limits the spread of infectious agents, and reduces energy and HVAC maintenance.
