May also contribute to mould growth

People with immune systems already made vulnerable by illness can suffer and even die if they are exposed to diseases they did not have when they were admitted to hospital.
We have gradually become more aware of the problems caused by Legionnaire’s disease and, miore recently, the so-called MRSA superbug in hospitals. It’s focused the attention that healthcare facilities such as hospitals need to pay to indoor air systems, such as ventilation ducts, in wards and in laundries.
Patients with pre-existing health problems, the frail elderly, people with cancer who are going through treatment, and those who may have depressed immune systems are likely to be among the most susceptible to such airborne infections. Hospitals also have special units that need particular attention to indoor air quality such as bone marrow units, neonatal intensive care units, and burn units.
But patients are not the only hospital occupants who are vulnerable. Hospital staff are more exposed to all kinds of illnesses and infections as part of their daily work and protecting their health is important to ensure they can perform their medical and nursing duties effectively and at maximum efficiency. Disease causing organisms can enter the building on air supply, feed on moisture produce, breed in reservoirs installed.
For example, Leghionnaire’s disease was named after an incident in Philadelphia, USA< where, in 1976, 34 members of the American Legion who were attending a convention died of a previously unnamed form of pneumonia. Investigation found that the bacterium was distributed by the air-conditioning system. Biological contaminants such as bacteria, mould, and viruses can breed in stagnant water that has gradually accumulated in ducts, humidifiers and drain pans of the ventilation system.
It can be a particular problem in older buildings and all parts of the humidification and dehumidification systems must be kept clean and dry to prevent growth of bacteria and fungi.
If they are not microorganisms can become airborne and there’s a risk of infection for patients with suppressed immune systems. Moisture located in other areas may also contribute to mould growth from increased humidity. For example, certain respiratory care equipment produces a lot of mist, which can increase the humidity levels in a room.
The basic differences between controlled environment by air conditioning for hospitals to take care of the above mentioned factors and that for other building types stem from the need to restrict air movement in and between the various departments and from the specific requirements for ventilation and filtration to dilute and remove contamination in the form of air-borne microorganisms and viruses.
It’s most important, therefore, as part of its regime for protecting vulnerable patients from additional and possibly life threatening infections not only to have effective hand washing and hygiene rules for staff and visitors but also to have a regular regime of air duct cleaning in place.
There are plenty of specialist duct cleaning companies that are experienced in dealing with maintenance and cleaning of duct systems in large buildings.
All such programmes should include regular inspection, maintenance and documentation of ducts and cleaning and replacement of filters and the specialist companies can provide all this.
