The 2 HVAC Standards Every Plant Manager Needs to Understand March 11, 2020



Heavy level of hygiene as defined by IRHACE HVAC Best-practise Guideline


Knowing what standards the air quality of our HVAC system needs to comply with is often frustratingly unclear for any plant manager. 


The minefield of regulations is complex and riddled with industry jargon. 


However, HVAC hygiene is still imperative in protecting our food-producing facility from pathogens. 


Let’s break down the two most important HVAC standards you need to understand as a plant manager. 

  1. ASNZ 3666.2: Air-handling and Water Systems – Microbial Control – Operations and Maintenance

  2. IRHACE HVAC Best Practise Guideline: an industry-developed HVAC hygiene best-practice guideline, modified for New Zealand by IRHACE. Although this is not law, you would need to  be able to demonstrate you are following an equally effective standard yourself should you choose not to follow it. 


Put down the Nurofen.  That massive headache is about to end. 

But it will take a while, so pull up a chair and enjoy the ride.


We have created a separate resource on each standard to keep this as simple as possible.  Please click the links above to read each summary.
