Cleanrooms
Handover cleaning where particles are measured
A laboratory, a production room or a clinical space after construction is not judged by eye but by a particle counter. The work is the same work — but to the facility’s procedure, with approved chemicals, and with every stage recorded.
- Not finished until the space passes its test
- I work to your facility’s cleaning procedure
- Chemicals, stages and hours documented
What is included
How I work in a controlled space
I do not carry out classification testing and I do not issue certificates — that is the testing body’s job. I prepare the space for the test.
- Work from the clean space towards the dirty space, never the reverse
- HEPA-filtered vacuuming only — no brooms and no blowers
- Non-shedding microfibre wipes, used once per zone
- Approved chemicals only, from the facility’s own list
- Treated water for the final wipe where it is required
- Dedicated garments, overshoes and gloves per the procedure
- Supply ducts, diffusers and filter faces cleaned externally
- Vinyl and epoxy floors — cleaned in two passes
- Records: who worked, when, with which product, in which zone
- A repeat clean after testing, if testing calls for one
Before we start
What I need to know from you
Every facility has its own procedure, and I work to it rather than to a generic one. To quote accurately I ask for these details up front:
- The classification required and who the testing body is
- The facility’s list of approved chemicals
- Entry procedure, garments and any induction I have to complete
- Whether the air-handling system runs during cleaning
- Time windows — before testing, after testing, or both
Frequently asked
Cleanrooms — the recurring questions
Do you issue a cleanroom classification certificate?
No. Classification and particle counting are done by an accredited testing body. I carry out the cleaning that lets the space pass the test, and document exactly what was done.
Are you inducted before entry?
Yes. I complete whatever induction you require, including gowning and entry procedure, and so does anyone I bring in with me. If the induction is run on your side, I will attend it before work starts.
What if the test fails?
I come back and re-clean the zones that were flagged. If the failure came from my cleaning, at no extra cost — the job is not finished until the space passes. If it came from works continuing in parallel, we will agree a price for another pass.
Do you work in hospitals and operating theatres?
In clinical spaces after construction, yes — with management’s agreement and in approved hours. In live operating theatres, no: that calls for a medical cleaning contractor with separate accreditation.
Have a facility going to test?
Send the cleaning procedure and the classification required, and I will come back with a quote and a programme.
