Decontamination & H₂O₂ Fogging for Critical Environments

CFS Site Services provides specialized H₂O₂ fogging and room decontamination services for cleanrooms, laboratories, GMP spaces, research environments, and other contamination-sensitive facilities. Our process can be combined with detailed physical cleaning, surface disinfection, and site-specific protocols to help reduce microbial contamination and support a controlled, documented return to service.

Whether performed as part of a scheduled preventive decontamination program, contamination-response event, post-construction cleaning, shutdown, maintenance activity, or pre-certification preparation, our team develops each treatment around the size and configuration of the space, operational requirements, and facility-specific procedures. CFS provides a coordinated approach from pre-cleaning and preparation through fogging and post-service support to help facilities restore critical spaces efficiently and with confidence.

CFS Site Services provides detailed pre-fogging physical cleaning to remove dust, debris, residues, and surface contamination before H₂O₂ treatment. This critical preparation step helps improve decontamination effectiveness by ensuring exposed surfaces are clean, accessible, and properly prepared for the fogging process.

Our teams can perform comprehensive cleaning of floors, walls, doors, fixtures, equipment exteriors, horizontal surfaces, and other critical touchpoints using site-approved procedures, chemistries, and cleaning tools. By reducing the physical soil load before decontamination, CFS helps create the conditions needed for more consistent treatment coverage and a more controlled return to service.

CFS Site Services provides rapid-response emergency and contamination-response cleaning for cleanrooms, laboratories, GMP spaces, and other critical environments following spills, contamination events, maintenance activities, or unexpected disruptions. Our trained teams mobilize quickly to perform targeted cleaning, disinfection, and decontamination using site-specific procedures designed to help restore the area safely and efficiently.CFS Site Services provides specialized high-bay and overhead dust removal for data centers and mission-critical facilities, targeting dust and particulate buildup on structural beams, piping, cable trays, conduits, ducts, and other elevated surfaces. Our teams use controlled methods and appropriate access equipment to help protect sensitive environments and maintain a cleaner facility from floor to ceiling.

CFS Site Services provides specialized cleanroom and GMP decontamination services for pharmaceutical, biotechnology, medical device, and other regulated environments where contamination control is critical. Our trained teams follow site-specific procedures, approved chemistries, and documented cleaning protocols to support the decontamination of floors, walls, ceilings, fixtures, equipment exteriors, and other critical surfaces.

Services can be performed following contamination events, shutdowns, maintenance activities, construction, certification preparation, or as part of a scheduled preventive program. When appropriate, physical cleaning can also be combined with H₂O₂ fogging and post-service verification to provide a more comprehensive contamination-control approach.

CFS Site Services provides specialized equipment and surface decontamination for laboratories, cleanrooms, GMP spaces, and other controlled environments. Our trained teams can clean and decontaminate laminar flow hoods (LFH), biosafety cabinets (BSCs), fume hoods, shakers, incubators, cold rooms, water baths, centrifuges, eyewash stations, safety showers, equipment exteriors, work surfaces, shelving, and other critical laboratory areas using site-approved procedures and chemistries.

We also support mold-affected environments, including cold rooms and other moisture-prone spaces, with detailed physical cleaning, surface decontamination, and targeted treatment programs designed to remove visible contamination and help reduce the conditions that contribute to recurring microbial growth. Services can be combined with H₂O₂ fogging, periodic preventive cleaning, and post-service verification when appropriate for the facility.

CFS Site Services can support environmental monitoring and post-decontamination verification before, during, and after H₂O₂ fogging to help document treatment effectiveness. Services may include pre- and post-service viable air sampling, viable surface sampling, and other site-specific monitoring methods to establish baseline conditions and evaluate environmental recovery following decontamination.

During the fogging cycle, chemical indicators (CIs) and biological indicators (BIs) can be strategically placed throughout the treated space to help verify H₂O₂ exposure, distribution, and process performance in accordance with the facility’s approved protocol. Results can be incorporated into a documented service package to support quality review, contamination-control programs, audit readiness, and return-to-service decisions.
