Legionella prevention control and treatments for Hotels and Resort

To deal with the problem scientifically Legionella, we must first take note that: "THE LEGIONELLA LIVES AND GROWS IN THE WATER, BUT IS TRASMITTED BY AIR."

It is not enough to analyze and take action on water quality, as in closed areas the two systems interact (vapors of hot water of the hot tubs, faucets and showers are captured from the air conditioning vents shooting infecting the heat exchange coils resulting in multiplication and spread of pathogens).
A serious and effective prevention intervention should therefore be a regular monitoring of the water supply systems and air handling.

In confined environments air conditioning systems not only perform the functions of control of the thermal conditions, but also that of all the filtration of particles dispersed in air. A direct consequence of this feature is the accumulation of chemical and microbiological contaminants that, saturating the system, paradoxically transform it into a source of pollution and contamination.

Apart from the obvious health and hygiene implications this causes an increased cost of about 15% of system management for the increased resistance that meets the air, the decreased efficiency of heat exchange coils, the acceleration of the natural process of corrosion of dehumidification system and batteries, etcc ..

As regards health and hygiene implications, the effects of a air treatment system in poor hygienic conditions involve:

1. chemical contamination due to the accumulation of pollutants coming from inside (through the circuit of recovery and recirculation) and externally (through external vents) as fine dust, particulates, carbon monoxide, sulfur dioxide , nitrogen dioxide, sulfuric acid, carbon disulfide, ozone, benzene, toluene, xylene, etcc ..
2. microbiological contamination due to the growth of microorganisms animals (Staphylococcus aureus, Pseudomonas aeruginosa, Legionella pneumophila, Streptococcus hemoliticus, mycobacterium tuberculosis, adenovirus, rhinovirus, coronavirus, etcc ..) and vegetable (Aspergillus, Cephalosporium, Streptomyces, Trichoderma, Cladosporium, saccharomyces , etcc ..).

The 'World Health Organization, at the conclusion of a series of studies conducted in the last two decades by researchers around the world, has counted among the causes of the abnormal increase of allergic diseases and the disturbing resurgence of tuberculosis, even air conditioning systems insufficiently sanitized.

The need to ensure a good quality of air you breathe in the confined spaces found its first translation rules in 1989 with the European Directive No. 89/391 / EEC and 89/654 / EEC, which dictated the minimum provisions of health and safety to be respected in the workplace.

The Sterilair ltd has developed an operational plan that will allow hotels and fittings to ensure customers and to those who work and attend a local healthy environment in which they have been carried out all the preventive measures to avert the risk of contagion of Legionella and other pathogens.
Even the Maltese law (lex n. 5 and 6 of 2006) has identified the legionella as an enormous potential health hazard indicating strategies to prevent the dangerous consequences.

As for the maintenance and prevention our project includes:

• Fan-coil units and Split Air Conditioners cleaning
• Air Duct UTA and HVAC Cleaning for centralized systems

Three analyzes, carried out every four months,of cold and hot water in the entrance area, in the middle area and in the most distant for the research of Legionella.

We can also put at your disposal on loan or for free to use a portable air purifiers (Health Pro 250) of Swiss manufacture, equipped with HEPA filters that trap fine particles, bacteria, viruses and allergens and filters activated carbon to reduce all kinds of smells, including tobacco smoke. These devices may be useful for guests demanding or suffering from allergies, asthma or other lung diseases unfortunately more and more frequent.

This service may be used as an added value to the already high quality of services provided by the hotel and increase its propaganda image.

We performs the work following the methodologies, protocols and standards of NADCA (National Air Duct Cleaners Association) which is the world's leading authority of reference for the remediation of aeraulic systems. Our technical director and the project manager is a chemical that qualify for ASCS (Air Systems Cleaning Specialist) and VSMR (Ventilation System Mold Remediator) n. 2080806 issued directly by NADCA Washington (USA).
