People first,
then the cause.
A clinical case, a cluster or an analytical result above threshold call for two different timescales: immediate protection of those exposed and structural resolution of the problem. We handle both, and we support the site in its dealings with the health authority.
The first hours
decide everything.
In the first hours after a report the priority is not to work out where the contamination comes from: it is to stop anyone else being exposed to it. A physical barrier at the point-of-use is the only measure with immediate effect, while the investigation starts in parallel.
Five steps,
in this order.
The sequence is not negotiable: protection precedes investigation, investigation precedes remediation, remediation precedes verification. Reversing the order means exposing people while the cause is still being sought.
Making the systems safe
Installation of point-of-use antibacterial filters with a 0.2 µm membrane on the showers, shower heads and taps of wards and critical areas: sterile water at the outlet from the moment of fitting, without shutting the system down and without building work. Where required, temporary isolation of unprotected outlets and shutdown of circuits with an aerosol risk.
Support with the local authorities
Technical support in dealings with the ASL, ATS and Prevention Department: preparation of the documentation required, attendance at joint site visits, reconstruction of the chronology of works, drafting of the technical report and of the recovery plan agreed with the supervisory body.
Environmental investigation
Targeted sampling to pinpoint the origin of the colonisation: distribution network, storage, recirculation, an individual outlet or the air handling system. The sampling plan is built on the epidemiological hypothesis, not on a standard template.
Definitive remediation
Air Pulse Technology intervention on the affected portion of the network or on the whole system, combined where appropriate with chemical or thermal shock, with post-treatment analytical verification at accredited laboratories.
Recovery and prevention plan
Update of the Water Safety Plan and the risk assessment, new control measures, reinforced monitoring at tighter frequencies and support with internal and external communication.
Antibacterial filters:
the barrier that works
within the same minute.
The hollow-fibre membrane with an absolute pore size of 0.2 µm retains Legionella, Pseudomonas aeruginosa, atypical mycobacteria, amoebae and fungi. It does not reduce the load: it excludes it, mechanically, in the last centimetre before the user.
- Immediate installation on shower, shower head and tap with no changes to the system
- Effective from the first second of use, whatever the state of the network upstream
- Declared service life of up to 31, 62 or 92 days by model and conditions of use
- Single-use versions and versions with a reusable cartridge and sanitisable body
- Suited to wards with vulnerable patients, intensive care, oncology, transplants and dialysis
- Usable as a bridging measure during remediation or while awaiting structural works
The four situations
that call for
an immediate response.
Confirmed clinical case
A case of legionellosis linked to the site, notified by the health authority or reported by the occupational physician.
Cluster or multiple cases
Two or more related cases in the same period and the same site: an environmental epidemiological investigation is triggered.
Analytical result above threshold
A test report exceeding the action levels set by the Guidelines for the building’s intended use.
Order from the supervisory body
An order or formal notice imposing measures and deadlines: this needs a documented technical response, not just an intervention.
