Hospital theatre verification work

Intech’s highly-trained engineers undertake comprehensive on-site cleanroom validation services, as governed by BS EN ISO 14644 and GxP/GMP.

Our services include a detailed scope of testing from air volume flow rates, differential pressures and HEPA filter integrity leak testing to microbiological air sampling and analysis.

As part of our work, we calculate the air change rates of each facility, in accordance with GMP (good manufacturing practice), the Orange Guide (MHRA rules, and Guidance for Pharmaceutical Manufacturers and Distributors 2015) and current ISO standards, including ISO14644.

In the case of private and NHS hospitals, we help clients identify compliance to HTM 03-01, specialised ventilation for healthcare premises, HBN 04-01 and HBN 13 for SSD departments.

To ensure our customers and the relevant regulatory authorities are furnished with the correct documentation, our engineers produce clear, concise and comprehensive cleanroom validation reports, containing all the necessary information and data.

Intech staff frequently operate out of hours and during shutdown periods – meaning minimal disturbance to our customers.

Cleanroom validation

Where we work

Our customers include pharmaceutical and bio-tech R&D and manufacturing, CDMOs, healthcare/hospital facilities, including theatre suites, aseptic and non-sterile cleanrooms, pathology laboratories etc.

To compliment our cleanroom validation service, we also validate the following clean air cabinets:

  • Laminar flow benches
  • Pharmaceutical isolators 
  • Class II microbiological safety cabinets 
  • PCR cabinets
  • Weighstation enclosures 
  • Fume cupboards
  • Downflow booths

This service is especially useful for clients because one vendor is looking after several disciplines, often during a single pre-arranged visit.

  • Pharmaceutical and bio-technology
  • Clean air cabinets
  • NHS and private hospitals

What we test

  • GMP Grades A, B, C and D
  • ISO graded cleanrooms from ISO 5 to ISO 9
  • DOP HEPA filter testing
  • Air flow velocity measurements and air change rate calculations
  • Differential pressure measurements
  • Differential pressure gauge calibration
  • Airborne particulate cleanliness counts (at-rest and operational)
  • Room recovery rate testing
  • Temperature, relative humidity, light and noise readings
  • Airflow visualisation studies
  • Temperature and humidity mapping of rooms and facilities
  • Post validation VHP decontamination of rooms and equipment

Intech has been a supplier to our department for over five years and in that time has constantly demonstrated their ability to competently provide a wide range of technical services. Prior to using Intech we had to deal with numerous suppliers several times throughout the year. Having a single company to contact has made the management of our various calibration and validation activities much simpler. We have saved a lot of time which has enabled us to use our limited resources on other aspects of our work.
