Ozone. Some Basic Facts:
On planet earth there 5 groups of living organisms:
1) Plants 2) Animals 3) Fungi 4) Bacteria 5) Viruses
This same grouping would also apply to size. 1) The tallest plant, the Californian Redwood tree at 115 m. (380ft). 2)The largest animal the Blue Whale at 30m long, 100 ft. and weighing 150 imp. tons, more than twice the size of any dinosaur that ever lived. 3) Bacteria vary in shape and size. Only in a group of many tens of thousands, termed a colony can they be seen with the naked eye, while a single bacteria can only be seen under a conventional microscope. 4) Viruses likewise vary in shape and size but are far smaller. A grain of salt would be 10,000 times as large as a virus and it was only in the 1930’s that a virus was first seen under an electron microscope. There are good and bad amongst bacteria and viruses. Over millions of years all living organisms, including man, have developed the ability to live with both. Periodically a newer, sometimes more virulent strain of virus will appear which has been known to play havoc until some means has been found to control the problem.
The ability to control the harmful effect of a virus on man was first achieved by Jenner who in the late 18th century scratched a liquid made from a secretion collected from a cow onto the skin of a person to give protection from smallpox, a viral disease that annually killed many thousands. A term called vaccination. Today the principal is the same. Inactivate a virus, and then give it in the harmless inactivated form to an individual, usually by injection, who will then develop antibodies that in turn will recognise and destroy the virus. This is the means used to protect young children from measles, or Polio. Developing a vaccine to combat a new viral strain takes time. In addition to vaccines we also need to rely upon additional supportive methods, of which there are many. These will invariably include; Quarantining individuals who might be carrying an infection in its early stages; Isolating known cases; Frequent cleansing hands with soap and water; Use of barriers such as face masks, even goggles and protective clothing; Avoid gathering amongst crowds, such as cinemas, sports venues, and theatres; Sprays of bactericidal and viricidal liquids on the ground to reduce incidence of organisms being transmitted on footwear; Use of bactericidal and viricidal gases such as ozone. Viruses and the vast majority of bacteria can be inactivated and destroyed by exposure to ozone gas that can even be produced from a small portable commercial generator in settings such as conference halls, conference rooms and offices, hotel rooms, cruise ship cabins and healthcare facilities.
Ozone will destroy a virus in a concentration of 2 parts per million in less than two minutes, and with greater humidity ozone is even more rapidly lethal.
While ozone occurs naturally in the air, its use for infection control will need a high concentration of ozone and thus must be controlled by excluding all persons from a room that is being cleansed with ozone. All Ozone Clean units are programmed to produce a rapid concentration of ozone for a specified time after which it rapidly and completely destroys any residual ozone, converting it back to the oxygen we all normally breathe. Following this programmed cycle, the generator can easily be moved to another room where cleansing might be needed. The efficacy of ozone will depend upon a number of simple easily regulated factors, such as the quantity used, and humidity.
- Ozone is a colourless gas which is safe to use. Following production, it rapidly decomposes into oxygen within 30 to 60 minutes leaving no other chemical by-products.
- The ozone generating equipment can be managed by an adult with little more than a short period of instruction and training. On average, 30 minutes.
- Ozone is an extremely powerful odour remover in addition to its ability to destroy viruses and bacteria on whatever surfaces and in the air.
- Has no deleterious effect on foods or fabrics.
- Ozone generators are efficient and economical to use, require no other chemicals, and can be used time after time.For the technically minded:
Oxygen is a gas that contains 2 atoms, and in volume is present in almost 21% of the air we breathe, the remainder being nitrogen, a smaller quantity of carbon dioxide and some water vapour. Ozone is a gas that occurs whenever oxygen is exposed to a powerful electric field, causing it to acquire a third oxygen atom. In this form under normal atmospheric pressure it is unstable and rapidly breaks down into oxygen and releases a highly energised surplus oxygen molecule. This molecule has a very brief half-life of some 30 minutes. When in contact with the outer coating of a virus or bacteria, it combines with that membrane, causing its rapid destruction by what is termed oxidation. This process likewise speedily removes odours from the environment. Amongst the more important advantages of the use of ozone is the total absence of any danger of organism resistance, while at the conclusion of the cleansing cycle the only waste product is atmospheric oxygen.
