ASHRAE 188

Definition

A widely used standard that serves as the backbone for Legionella water management programs.

ASHRAE 188 is widely used as the framework for Legionella water management, and some jurisdictions and facility types reference it directly or indirectly. It frames Legionella control as a managed program rather than episodic test-and-treat. It supports designing for circulation, temperature control, and continuous awareness.
