MANAGERS' OBLIGATIONS IN RESPECT OF LEGIONELLA

The operator is obliged to carry out a risk assessment of the legionella infection with the consequent obligation to draw up the relevant document for self-control purposes.

This document must specify:
- the appointment of a person responsible for risk management, including the evaluation of the prevention policy and the application of control measures;
- risk assessment by means of a careful analysis of the normal operating conditions of the plumbing system in order to identify the critical points;
- inspection of the facility (map of the water mains);
- management of any detected risk from the plumbing system by creating the necessary corrective measures to minimise the risk highlighted.
 

Legislation

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

STRUCTURES AND WORK ENVIRONMENTS AFFECTED

- Tourist accommodation facilities (hotels, hotels, guesthouses, inns, campsites, residences, farm holiday centres, bed & breakfasts, holiday homes, rooms to let, cruise ships, etc.)

- Spas

- Public facilities (sports and leisure facilities, gyms, shopping centres, trade fairs, exhibitions, wellness centres, etc.)

SOLUTIONS FOR LEGIONELLA RISK MANAGEMENT

Dosage: SANITER LP 100
Purpose treatment: sanitising-antiscalant-anticorrosive, against organic proliferations and protection against Legionella Pneumophila in sanitary water circuits, particularly indicated against Legionella Pneumophila.

Dosage: SODIUM HYPOCHLORITE (CHLORIDE)
This is the most widespread disinfection treatment that guarantees the hygiene of water, but can generate toxic by-products and alters the taste of the water. The pH and temperature have a major influence on the effectiveness of disinfection.

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

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

The treatment does not change the smell or taste of the water in the slightest.
If appropriately sized, the results can be optimal, UV systems can also be used to support chemical dosing to reduce the amount of the same.
