Abstract
Legionelose is an illness produced as a consequence of the inhalation of bacteria of the specie Legionella, which occasionally may colonize some of the water installations of the buildings.
This article describes a Legionella risk assessment algorithm particularized for every type of installation covering all the specific characteristics of every piece of equipment, but keeping a common similar structure that allows easiness of use and homogeneous results. This algorithm has been developed by the Experts Commission of the Ministry of Health.
The main use of these kind of tools is to minimize as much as possible the subjectivity of the inspectors in the identification and assessment of risks associated to the installations. These types of algorithms are applicable in risks depending on a relative low number of parameters that are somehow easy to control, as it happens in the water installations in the buildings.
It has been chosen to develop a global index rated from 0 to 100 (meaning 0 minimum risk and 100 maximum risk) distributed in term in three sub indexes, which define the main risk aspects to be taken into account.
- Structural Index: design.
- Maintenance Index: maintenance quality.
- Operational Index: performance of the equipment.
Covering all the different aspects of the life of the installations.
