Legionellosis often represents a not considered risk in biological risk evaluation of schools, but epidemics have been discovered in environments like schools, hotels and hospitals
Security measures has been immediate for the infected rooms. These measures have been activated by a major's decree to debilitate the dangerous bacterium
There are two types of Technical Inspection: the Preliminary type which is carried out in the event the Visual inspection does not manage to clarify all the doubts concerning the hygiene of the system or the type of corrective action to take and is aimed at obtaining a correct view of all the problems that the system has. The Conclusive type which follows the corrective action for maintenance, cleaning and sanitisation is carried out with the precise aim to document the results obtained in a comprehensive manner.
In both cases the method used by Alisea , requires complex analytical activity, including the following stages:
This stage involves cleaning all system elements found to be in poor hygienic condition, according to the methods which are most suitable to the structural characteristics and to the type of residues found in the installation. In this phase the following activities can be carried out:
Alisea, during more than ten year experience in the field, has studied and rendered operative more than a remediation system, because often the structure and accessibility characteristics mean that different technical solutions need to be found, each one being only effective on a specific part of the device. Among the work methods used by Alisea’s technical staff one could include:
In the certification phase reporting and advice activities are of prime importance in order to establish a strict regime of legal protection. For companies like Alisea S.r.l. who is UNI EN ISO 14001:2004 and UNI EN ISO 9001:2008 certified it is of fundamental importance that all the documentation and forms produced in this phase are inserted into the “Air Section” in the Environmental Management Manual.
In this phase a Health-Hygiene Maintenance Plan is created and drawn up, aimed at keeping health and safety parameters of the system high. All future health-hygiene and maintenance action the relative time frames are indicated in the plan.
In this phase a Health, Hygiene and Maintenance Register is drawn up in which all ordinary and extraordinary work carried out on the system is recorded.Back to top
