Do you want to contribute to the health of its staff and the public in general and ensure compliance with the existing legislation?
The Royal Decree 865/2003 establishes the hygiene measures necessary for the prevention and control of legionella.
Gesplasur can evaluate its facilities of risk, potential stations of aerosols, and designing appropriate maintenance programmes to prevent the possible development of this dangerous bacteria.
Our technicians are highly qualified and all our services staff has attended the mandatory courses homologated (according to order SCO/317/2003), and has great expertise to carry out all the treatments and analytical controls necessary for any type of facilities
Introduction to legionella
It is a bacterium in the form of Bacillus of 0.5 to 0.7 microns wide and 2 to 20 microns in length. It belongs to the Group of gram-negative bacteria and this equipped with flagella that facilitate their mobility. It does not present forms of resistance (spores).
It belongs to the family Legionellaceae, which are known around 30 species and more than 50 serogroups. Legionella pneumophila is responsible for more than 90% of infections; It consists of 15 serogroups serogroup 1 is the most frequent.
The Legionella bacterium was discovered in 1976 as the agent responsible for producing a lung disease severe human. It was identified as the causative germ of a respiratory disease outbreak recorded in 1976 that hit 182 people attending a Convention of the American Legion in a Philadelphia hotel. It was named Legionella pneumophila and disease that causes, "legionnaire's disease".
Legionnaire's disease is typically found naturally associated with aquatic environments (rivers, lakes, etc.). These natural environments can pass to water distribution systems, reaching colonize buildings distribution networks.
This bacterium which has colonized our facilities can penetrate into our respiratory system via aerosols, producing very serious illnesses in certain conditions.
The bacteria requires a series of environmental conditions that favour their proliferation and their development, as well as the existence of generators of aerosol devices, so that it can penetrate into the respiratory system of the man.
Nowadays the infection should be considered perfectly controllable always take appropriate measures, such as the establishment of a therapy in patients and the control of the buildings.
Where do you live?
The natural habitat of Legionella is water, so that we can find in nature in rivers, lakes, ponds and fountains; associated particularly with the existence of sludge and organic matter, which act as a source of nutrients.
From its natural reservoir pass bacteria to colonize the supply systems of cities and, through the distribution network, joined household water facilities or other facilities that require the use of water to operate (systems of refrigeration, irrigation, swimming pools, tunnels, washing, etc.).
Frequently, these facilities have elements, known with the name of amplifiers, in which occurs the water stagnation and accumulation of products that serve as substrate for the bacteria (sludge, organic matter, material corrosion, amoebae, other bacteria, etc.) enabling its multiplication to infective concentrations for the man.
What you need to survive?
-By below 20 ° C: remains sleeper
-Between 35-37 ° C: optimum development
-Per above 60 ° C: die 90% in 2 hours
-Per above 70 ° C: die 100% quickly
Legionella causes legionellosis, that can present two forms of disease:
Risk of individual factors for developing the disease are:
How is it transmitted?
Legionellosis is contracted through the respiratory tract by inhalation of aerosols or aspiration of water containing the bacteria legionella in high quantities.
Aerosols are formed from droplets which may arise to spray water or breathe air bubbles through it. Much smaller than the drops, the more dangerous they are. Droplets whose diameter is less than 5 µ arrive more easily at lower respiratory tract.
The risk of contracting the disease will depend on the concentration, type and virulence of the bacteria in
aerosol and the exposure time.
Transmission from person to person and not from ingestion has not been declared.
Installations that can be a source of pollution are those which, after being colonized by legionella, favour the proliferation of bacteria and produce aerosols.
The following are potential hotbeds of legionellosis:
Prevention of legionellosis
To prevent legionellosis we must act on the 3 stages that relate to the following:
Regulations on Legionella
Royal Decree 865/2003
Royal Decree 865/2003 , 4th of July, whereby the hygiene criteria for the prevention and control of legionellosis. It is the law of obligatory, existing and implementation throughout the Spanish territory. Some autonomous communities have specific legislation thereon, which shall be taken in the geographical area of the corresponding community.
See the Royal Decree 865/2003
Norm UNE 100030-2005
Guide for the prevention and control of proliferation and spread of legionella in facilities. It is a guide which should take into account when it comes to the design of facilities and their maintenance, as outlined in article 6 of the RD 865/2003.
The Ministry of health and consumer guides
Compilation of specific guides, sorted by chapters that relates in detail the characteristics of design, comprehensive maintenance and assessment of risk of legionellosis in each type of installation. It is not mandatory, but it has become an excellent reference guide for the elaboration of preventive maintenance programs.
ROYAL DECREE 865/2003
The Royal Decree 865/2003 applies to installations which use water in their functioning, produce aerosols and are located in the interior or exterior of buildings of collective use, industrial facilities or means of transport may be susceptible to become foci for the spread of the disease during its operation, testing, maintenance or service.
Article 2. Classification of the facilities at risk:
2 Facilities with smaller proliferation probability and dispersion of Legionella:
3. Risk in respiratory therapy facilities.
Article 8. Maintenance on-site programs. Laying down hygiene maintenance programmes suited to the characteristics of each installation, and shall include at least the following:
1. For installations of greater proliferation probability and dispersion:
2. For installations smaller proliferation probability and dispersion:
Specific conditions for maintenance of systems for hot and cold water for human consumption are set out in annex 3, the cooling towers and evaporative condensers are reflected in annex 4, and guidelines for the maintenance of bathtubs and hydromassage pools of collective use are contained in annex 5.
Other facilities are not developed in the RD 865/2003, so operations will be based on the
assumptions related to similar systems and in the guides of the Ministry of health and consumption patterns.
Article 4. Responsibility of the operators of the installations. It establishes that holders of the installations described in article 2 shall be responsible for the compliance with provisions of this Royal Decree and that periodic maintenance programs, carried out improvements in structural and functional facilities, as well as control of the microbiological and physico-chemical quality of the water, so they do not pose a risk to public health. The hiring of an outside maintenance service does not exempt the holder of the installation of its responsibility.
Article 13. This article passes all the staff who work on hygiene maintenance, belong to an entity or contracted external service or either own installation staff, must be completed the courses which it approves for this purpose the Ministry of health and Consumer Affairs at the proposal of the corresponding autonomous communities, in accordance with the order SCO/317/2003, of 7 February, by which regulates the procedure for the approval of training courses of personnel which performs the operations of sanitary maintenance of installations subject to the Royal Decree.
In addition, all biocidal products that are used to perform treatments must be registered. For indoor domestic hot and cold drinking water installations, chemicals used for treatment of the facilities must comply with to do so in Royal Decree 140/2003 of 7 February, whereby health criteria of the quality of water for human consumption.
Shall comply also with the norm UNE-EN corresponding, as required by the order SAS/1915/2009, of 8 July, on substances for the treatment of water intended for the abstraction of water for human consumption, which regulates the Royal Decree 140/2003.
