Glossary terms that help connect the sector workflow with sampling, microbiology, traceability and reporting.
-
Legionella is a bacterial genus associated with risks in water installations that generate aerosols, such as domestic hot water, showers, spas, cooling towers or HVAC systems. Its control requires planning, sampling, laboratory analysis and documented actions.
Sector relevance: Central to building water-risk workflows where assets, terminal points, aerosols, samples and corrective actions must remain traceable.
-
Domestic hot water is a building or facility hot-water system. It can be relevant in Legionella prevention programs and aerosolization risk control.
Sector relevance: Useful for selecting the right method, product family, sampling point, report or traceability workflow in water quality programs.
-
Aerosolization is the formation or release of fine droplets that can carry microorganisms from water into air. It is relevant in showers, towers, spas and other installation-risk assessments.
Sector relevance: Useful for selecting the right method, product family, sampling point, report or traceability workflow in water quality programs.
-
A terminal point is the final outlet or point of use in a water system, such as a tap, shower, hose or process connection where exposure or sampling may occur.
Sector relevance: Useful for selecting the right method, product family, sampling point, report or traceability workflow in water quality programs.
-
A biofilm is a microbial community attached to a surface and protected by an extracellular matrix. In water networks it can act as a reservoir of microorganisms and contribute to recontamination.
Sector relevance: Useful for selecting the right method, product family, sampling point, report or traceability workflow in water quality programs.
-
Royal Decree 487/2022 is the Spanish regulation on prevention and control of legionellosis in installations that can generate aerosol exposure.
Sector relevance: Useful for selecting the right method, product family, sampling point, report or traceability workflow in water quality programs.
-
ISO 11731 is an international standard for enumerating Legionella in water. It is relevant for control programs in facilities, domestic hot water, towers, spas and aerosol-risk systems.
Sector relevance: Useful for selecting the right method, product family, sampling point, report or traceability workflow in water quality programs.
-
ISO 19458 is a reference standard for microbiological water sampling planning, sampling procedures, transport, handling and storage before analysis begins.
Sector relevance: Useful for selecting the right method, product family, sampling point, report or traceability workflow in water quality programs.
-
A water safety plan is a documented plan that identifies risks, controls, sampling points, responsibilities, monitoring and corrective actions in a water system.
Sector relevance: Useful for selecting the right method, product family, sampling point, report or traceability workflow in water quality programs.
-
A deviation is an incident or nonconformity against a plan, procedure, criterion or expectation. It should be documented, assessed and closed according to procedure.
Sector relevance: Useful for selecting the right method, product family, sampling point, report or traceability workflow in water quality programs.
