Is Employee Illness affecting Productivity?
UV can Clear the Air

Written by Janice M on . Posted in Hygiene & Quality Control

Your workplace, clinic or laboratory may be suffering under the heavy burden of airborne germs … You can protect your environment from airborne pathogens and reduce infection with a simple UVGI system, that looks similar to a heater.

The prevalence of airborne diseases such as flu, TB and asthma has led to the initiation of infection control programmes in many companies, clinics, and laboratories.

The successful transmission of infection via the airborne route relies on several factors, including the survival of the airborne pathogen in the environment as it travels between susceptible hosts. Ultra-violet Germicidal Irradiation (UVGI) has proven to be effective in disinfecting airborne pathogens.

In the mid 1900s the world experienced an increase in TB related infections. Riley & Wells performed scientific trials that proved that UVGI does prevent the spread of TB infections. UVGI was implemented and a reduction in infection was recorded.

Through these trials, the world has embarked in UVGI implementation. The TB pathogen can be airborne for long periods, therefore with the use of UVGI, the air can be sanitized, thus reducing infections. Roderick Escombe ET AL (2007).

In Johannesburg, South Africa, tests by Professor Mike Dutton, Director, Food, Environment & Health Research Group, University of Johannesburg, found that "the use of a Sani Disc with TIO2 treatment of the interior face of the disc cover, in combination with the Sani 55, gave the best microbial sanitization, with up to 98 to 99% of Aspergillus and Penicillium species being eliminated by this treatment."*

How does Ultra-Violet Germicidal Irradiation (UVGI) work?

To learn how the UV air purifier works, it is necessary to first understand the function of UV lights. Ultraviolet light utilises its energy to break down the molecular bonds of the micro-organisms, thereby destroying the organism. In an ultraviolet air purifier, the particles and organisms present in the air enter the purifier and while passing by the UV rays, their molecular bonds are broken and they are destroyed.

UV rays thus destroy harmful particles and micro-organisms found in the air, including particles such as dust and dust mites, mildew, allergens, pollens, smoke, vehicle fumes, moulds, dead skin flakes and dander, as well as organisms like bacteria, viruses, fungi and other germs.

The UV air purifier gives out air that is cleansed and free of any harmful particles.

Benefits of UV Air Purifiers:

  • UV air purifiers help prevent airborne diseases like flu, pneumonia, tuberculosis and asthma by disinfecting the air and efficiently destroying the particles and organisms that can cause these diseases
  • Prevention of allergies
  • They prevent the growth of moulds in central air conditioners and cooling coils, thus eliminating the need to clean them regularly
  • They keep the room fresh and clean by eliminating odours
  • They destroy volatile organic compounds (VOC’s). Volatile organic compounds are harmful gases / vapours emitted by various products.
  • They give out negative hydroxil ions, a compound that removes pollutants from the atmosphere
  • Reduction of contaminants that may negatively influence the results of tests or experiments in the laboratory
  • Therefore: all of the above leads to better health and well-being of employees and increased productivity
