Slide 3: Bacteria and viruses are present in the air, on food, plants and animals
Bacteria and viruses are present in the air, on food, plants and animals, in soil and water — and on just about every other surface… 3
Slide 4: Most bacteria and viruses won't harm us, but some germs are difficult enemies
Most bacteria and viruses won’t harm us. However, some germs are difficult enemies because they're mutating to breach our immune system’s defenses. 4

Slide 10: What is UV radiation?
What is UV radiation? Ultraviolet (UV) light is invisible to human eyes. It can be subdivided into three categories: UV-C from 200 to 280 nm UV-B from 280 to 315 nm UV-A from 315 to 400 nm For medical use For disinfection purposes and (i.e. phototherapy to treat For use with curing, germicidal appli
Slide 11: How does it work?
How does it work? • UV-C radiation can break the DNA and RNA of bacteria, viruses and spores, meaning that they leave them harmless. There are no known micro-organisms resistant to UVC.1 • UV-C technology has been used safely and effectively in hospitals and governmental buildings for more than 40 y
Slide 12: Facts on UV-C and COVID-19
Facts on UV-C and COVID-19 • UV-C has been used extensively for more than 40 years in disinfecting drinking water, wastewater, air, pharmaceutical products, and surfaces against a whole suite of human pathogens • All bacteria and viruses tested to date respond to UV disinfection at the appropriate d

Slide 20: Using UV-C in a safe way
Using UV-C in a safe way • Like any disinfection system, UV-C lamps and devices must be used properly to be safe. • UV-C light can cause a severe sunburn-like reaction to your skin and similarly, could damage the superficial tissue of eye (photo keratitis), if exposed … this is very painful. It is,

Define dose and time required to eliminate the targeted pathogens Dose is based on intensity and time: × = W J Irradiance Time S UV dose m2 m2 • Micro-organisms need a different dose to be neutralized by UV-C. (see table) • Micro-organisms on surfaces that are not directly exposed to UV-C radiation
Slide 26: Upper air disinfection calculations (theoretical guideline)
Upper air disinfection calculations (theoretical guideline) 3 Calculation (Example) Requirements • Surface: 100m2 • 0.2 to 0.5 UV-C W/m2 • EOL: 80% • Humidity: 60% 1 Rules of thumb for radiation: Calculation • 0.2-0.5 W UV-C/m2 floor space • 0.15 W UV-C/m3 (100m2 * 0.35 W UV-C/m2 * 1,25)/0.8 = 54.7
Slide 27: Surface disinfection calculations (theoretical guideline)
Surface disinfection calculations (theoretical guideline) • Dose depends on type of virus and bacteria • Irradiance depends on the distance between UV source and object (surface): the longer the distance, exponentially lower irradiance (formula of Keitz) 1 Step 1 2 Step 2 Calculate longest distance
