Industrial hygienists are often the first, and sometimes only, line of defense against Legionella amplification in large facility water systems. But without accurate piping schematics or a structured assessment protocol, it’s easy to miss the hidden risks: dead legs, stagnation zones, temperature inconsistencies, and untracked system modifications.

For facility and EHS teams, understanding your piping system is no longer optional – it’s imperative for safety and compliance.
