On a medical project, difficulties do not always begin at the commissioning stage. They often appear much earlier, in a plan that failed to anticipate an operational constraint, a requirement that was translated too quickly, or a technical choice that seemed coherent on paper but proves problematic when confronted with real-world conditions. Identifying a difficulty […]

The design of operating rooms is constantly evolving to meet the requirements of the field, drawing on experience and knowledge to address operational needs. Contamination control, a key concern in healthcare facilities, is governed by the French reference standard NF S 90-351 (April 2013), entitled “Healthcare facilities — Controlled environment zones — Requirements for airborne […]

CFD simulation is a very useful tool when it comes to studying the resuspension and transfer of particles deposited in a cleanroom. Different numerical techniques can be implemented depending on the conditions and /en/controlled-environment/requirements. Cleanroom ventilation requirements can be better defined when it is possible to calculate the balance between contamination sources and the supply […]

Airborne disinfection can cause damage to cleanroom partitions, such as blistering or peeling paint. Solutions are available to repair or even prevent this phenomenon. As a specialist in the renovation of sandwich panels in cleanrooms, CEPI offers sustainable solutions to prevent or restore potential blistering issues that may appear on painted partitions when an airborne […]

The healthcare facilities are facing health challenges such as MDR bacteria (multidrug-resistant bacteria), VRE (vancomycin-resistant enterococci), and COVID-19, creating a sense of insecurity and helplessness. When the number of COVID patients admitted to the hospital decreased, we looked for a sufficiently effective disinfection solution that would allow us to resume regular activities and once again […]

After an interruption in pharmaceutical industry activities, many facilities exposed to microbiological risks will need to undergo a new cleanroom clearance process. When and how should a cleanroom clearance process be implemented? In the current context of the COVID-19 pandemic, vigilance is essential to ensure a safe resumption of activities. Indeed, following a prolonged shutdown […]

“`html Part 3 of ISO 14644 describes test methods and requirements for measuring instruments and procedures used to determine the performance parameters of cleanrooms and clean zones, with the exception of the following air cleanliness classification tests: Airborne particulate cleanliness (APC) classification, according to NF EN ISO 14644-1; Surface particulate cleanliness (SPC) classification, according to […]

This is a major event in the world of ultra-clean environments. For the first time in fifteen years, the revision of ISO 14644-1 has significantly changed the rules for cleanroom classification. Published at the end of February, this new standard revises the allowable particle concentration limits in the air and fundamentally changes the practical and […]

The two main guides dealing with environmental microbiological monitoring in healthcare facilities, published respectively by the South-West Coordination Centre for the Control of Healthcare-Associated Infections (CClin Sud-Ouest) and the Technical Committee for Nosocomial Infections and Infections Related to Care (Ctinils) in 1998 and 2002, both required an update. This has now been achieved with the […]
