MTE Solutions Cleanroom Compliance Checklist
MTE Solutions Cleanroom Compliance Checklist
Operators are the number one source of contamination in cleanrooms — proper apparel, cleaning protocols, ESD control, and documentation are all required to maintain ISO classification and pass regulatory audits. This checklist covers the essential supply categories for ISO Class 3–8 environments, with links to MTE Solutions products in each category. MTE Solutions has been a trusted cleanroom supplier since 1985, is ISO 9001:2015 and ISO 13485:2016 certified, and carries products from Keystone, ACL Staticide, Hakko, Vileda, Desco, and other leading brands.

Frequently Asked Questions
How do I determine which ISO class my cleanroom must meet?
ISO classification is determined by the maximum allowable particle count per cubic meter at a specified particle size, per ISO 14644-1. Your required ISO class is typically specified by your customer, regulatory body, or product standard — for example, USP <797> pharmaceutical compounding requires ISO Class 5 for critical zones, FDA Class II/III medical device assembly typically requires ISO Class 7 or better, and semiconductor fabrication may require ISO Class 3–4. If your classification is not specified by a standard, conduct a particle count survey of your environment and classify accordingly. MTE Solutions can help you identify the right consumables for your ISO class.
What is the most common audit finding related to cleanroom apparel?
The most common apparel-related audit findings are: incorrect gowning order (which transfers contamination from outer garments to inner garments), missing or improperly worn beard covers and hair covers (exposed hair is a major particle source), gloves not changed at required intervals or after contact with non-cleanroom surfaces, and use of non-cleanroom-rated apparel (standard lab coats or street clothing in ISO-classified areas). Documented gowning SOPs and regular gowning audits are required to maintain compliance — apparel alone is not sufficient without a verified gowning procedure.
How often should tacky mats be replaced?
Tacky mats should be peeled when the top layer is visibly saturated with debris and no longer tacky to the touch — typically daily in high-traffic areas, or more frequently in environments with heavy foot traffic or visible contamination. Do not wait until the mat is completely covered; a mat that is no longer tacky provides no contamination control benefit. Document mat replacement as part of your cleanroom cleaning log for audit traceability. Position tacky mats at all entry points, including gowning room exits and cleanroom entry doors.
