Cleaning, an Essential Element

Cleaning is an essential element of contamination control. That is why Harvard has established Standard Operating Procedures for Cleaning & Maintenance of Controlled Environments. Our SOP details cleaning regulations recommended as a minimum for the successful operation of a clean environment in compliance with Federal and ISO Standards, within their specified classifications, from class 1 (M1.5) to 100,000 (M6.5) or ISO 14644-1: Class 3 – Class 9. Our experienced team can help to develop an effective service program, or customize our staff training and work instructions to align with your established protocols and procedures.
