When a building empties its water risk does not pause. Here is how to flush, hold temperatures and recommission the system safely before people return.
Integrating Legionella records with facility management systems
How to fold Legionella monitoring into your FM or CAFM system so records tie to assets, survive an audit, and never let a green dashboard hide a missed check.
