EU GMP Annex 1, Section 8 - Utilities

What it says

Utilities supporting sterile product manufacture, including heating, ventilation and air conditioning systems, water systems and process gases, must be designed, qualified and monitored to consistently meet the quality attributes required for their intended use, with critical utility performance built into the site's overall Contamination Control Strategy.

Paraphrased for plain-language clarity. Always verify against the current published regulation text.

What it means in practice

• Utilities are often invisible in day-to-day operations until they fail, which is why this section expects ongoing qualification and monitoring rather than a one-time installation check.
• HVAC system performance directly determines whether a cleanroom can actually maintain its intended classification, so utility qualification data and room classification data need to be read together, not treated as separate compliance exercises.
• Process gases that contact product or product-contact surfaces, such as compressed air used for component drying, carry contamination risk that is easy to overlook compared with more visible utilities like water systems.

What inspectors look for

• Whether critical utilities are qualified and routinely monitored against defined quality attributes relevant to their use, not just checked at installation.
• Whether utility performance data is reviewed alongside cleanroom environmental monitoring data to confirm the two remain consistent with each other.
• Whether process gases that contact product or product-contact surfaces have documented quality controls appropriate to that contact risk.
