Groundbreaking Legionella prevention model reported
Number of cases has jumped since 2002
A groundbreaking hazard analysis formula showcased in the April 2019 issue of The Synergist, the magazine of the American Industrial Hygiene Association, is expected to significantly aid users in preventing Legionella growth in buildings' water systems. Designed by J. David Krause, Ph.D., MSPH, CIH, vice chair of AIHA's Indoor Air Quality Committee and a nationally known expert in toxicology, public health andrisk assessment, the tool evaluates the combined effectiveness of control measures used to prevent Legionella and other waterborne pathogens.
Recommendations to prevent Legionella growth in buildings' water systems involve periodically measuring water temperatures, disinfectant or chlorine levels and other parameters. But the amount of data that water management programs generate can be overwhelming, and few tools are available to analyze the numerous variables used to assess these water systems.
