MANAGERS' DUTIES IN THE MATTER OF LEGIONELLA

The operator has the obligation to proceed with the assessment of the risk linked to legionella infection with the consequent obligation to prepare the relative document for self-control purposes.

This document must specify:
- the appointment of a risk management manager who includes the enhancement of the prevention policy and the application of control measures;
- risk assessment through a careful analysis of the conditions of normal operation of the plumbing system in order to identify the critical points;
- inspection of the structure (map of the water network);
- management of any risk detected deriving from the plumbing system by creating the necessary corrective measures to minimize the highlighted risk.
 

Legislation

In the provision of May 7, 2015, the "Permanent Conference for relations between the State, the Regions and the autonomous provinces of Trento and Bolzano" renews and ratifies the agreement on the document "Guidelines for the control and prevention of Legionellosis" also unifying the various regional indications.

FACILITIES AND WORK ENVIRONMENTS CONCERNED

- Tourist accommodation facilities (hotels, guesthouses, campsites, residences, farmhouses, bed&breakfasts, holiday stays, guest houses, cruise ships, etc.)

- Spa facilities

- Structures for collective use (sports and recreational facilities, gyms, shopping centres, fairs, exhibitions, wellness centres, etc.)

- Healthcare, social-health and social-welfare structures
 

SOLUTIONS FOR LEGIONELLA RISK MANAGEMENT

Dosage: SANITER LP 100
Multifunctional treatment: sanitizer-antiscalant-anticorrosive, against organic proliferations and protection towards sanitary water circuits, particularly indicated against Legionella Pneumophila.

Dosage : SODIUM HYPOCHLORITE (CHLORINE)
It is the most widespread disinfection treatment which guarantees the hygiene of the water, but can generate toxic by-products and alter the taste of the water.The pH and the temperature significantly affect the effectiveness of disinfection.

Dosage: CHLORINE DIOXIDE
The search for a substitute disinfectant for chlorine has provided several possible solutions.While no disinfectant is perfect, chlorine dioxide is an excellent alternative given its characteristics.
Chlorine dioxide is an oxidizing biocide and not a metabolic toxin, this means that it kills microorganisms by interrupting the transport of nutrients through the wall cell phone, not through disruption of a metabolic process.
This allows for much lower dosages of chlorine dioxide to obtain a more stable residue than chlorine or ozone.

Dosage: ULTRAVIOLET< br />Germicidal ultraviolet radiation is a sterilization method that uses ultraviolet light (UV) at the UV-C wavelength, which modifies the DNA or RNA of microorganisms and therefore prevents them from reproducing or being harmful .

The treatment does not change the smell and taste of the water in the slightest.
If suitably sized, the results can be optimal, the UV systems can also be used to support chemical dosages for reduce their quantity.
