Newer Cleaning Technologies

Electrostatic Sprayers

These disinfection systems turn disinfectant liquid into aerosols and then apply a charge to each droplet so that they are attracted to surfaces through electrostatic forces greater than gravity. Manufacturers state that they could be used in a variety of facility types such as healthcare, nursing, schools, offices or sports facilities. Such sprayers have the benefit of allowing large volumes of surface areas to be disinfected in a much shorter period of time compared to traditional disinfecting techniques. The efficiency of these systems can result in operational savings where there are large surface areas to be cleaning such as auditorium seating and lobby areas. When used with the correct disinfectant, some manufacturers claim their systems are suitable for the disinfecting of fabrics, such as upholstered theatre seats, without discolouration to the fabric.

Only disinfectants approved by Health Canada and the manufacturer of the sprayer should be used.

UV-C (Ultraviolet-C) Lighting

Portable or fixed UV-C lights have the potential to kill COVID-19 on most surfaces. The length of time a surface needs to be exposed to UV-C light will depend on the manufacturer but can still result in labour savings over traditional disinfecting. UV-C lights are available in many shapes and sizes, and can be used in many different ways to disinfect a variety of items. Consideration could be given to disinfecting shared tools, consoles, lav mics, props, concession stands, road cases, first aid rooms, etc.

UV-C lights only work on “line of site.” If a surface is in a shadow, it will not be disinfected. For this reason, more than one light may be needed to address shadowed areas.

UV-C light is extremely dangerous to humans and can cause severe eye and skin damage with a very short exposure. Detailed safety protocols and training are required when using UV-C lighting.
