503A Traditional Compounding Pharmacies and 503B Outsourcing Facilities:

How to Optimize Your Compounding Cleanroom for FDA Inspections

As a result of the 2013 Drug Quality and Security Act (DQSA), all traditional compounding pharmacies and outsourcing facilities are subject to FDA oversight. Since enactment, the FDA has taken aggressive steps to strengthen enforcement and implement stricter standards for sterile compounding. Any “insanitary conditions” are in direct violation of Sections 501(a)(1) and (a)(2)(A) of the FD&C Act (Title 21 CFR), which gives the FDA inspectors broad secretion for determining what constitutes sterile conditions.

Because adverse events and sterility test failures are a surefire way to attract the undivided attention of the FDA and State Board of Pharmacy, experts in the field of pharmaceutical compounding strongly recommend using an ISO 5 cleanroom to substantially lower the bioburden of the cleanroom environment and restrict the number of colony-forming units (CFUs) introduced into the critical areas.

Specify the following for compliance with cGMP requirements:

  • 1 additional FFU in the Buffer Room
  • 1 additional FFU in the Ante-Room
  • Tier III Environmental Control System
  • BioSafe Class A FRP Panels

Please contact us to add these options to your compounding cleanroom.

Visit our USP/cGMP resource page for more information including a Terra webinar presentation and a white paper explaining the facility requirements for compounding pharmacies.

Door and Window Options

Automated Sliding Doors
A no-touch motion sensor opens sliding door for passage into or out of the clean room. Get single or double doors to transport personnel and carts with hands-free operation. Sliding doors conserve forward space and close automatically to preserve pressure and cleanliness within the controlled environment. Urethane wheels stay locked in upper and lower tracks to ensure smooth sliding, and a microprocessor monitors door position to adjust speed of movement and braking. Visit Automatic Sliding Door Systems for more details and ordering information.

Automated Swing Door Opener
For hands-free door opening when side-to-side space may be an issue, opt for Terra’s Automated Swing Door Opener. The space-saving unit fits above the swing door; trigger the door motion with the swipe of a hand in front of the sensor pad. Operation is quiet and open/close speed is programmable. An on-board power supply eliminates the need for secondary power. This opener can be installed on single or double doors, and is ADA-compliant. Visit Automatic Swing Door Opener for more details and ordering information.


Tempered Glass Window
The 0.5" double-paned tempered glass window is secured between two 304 stainless steel retaining frames; the internal frame has no fasteners or other cleaning obstructions. Standard size: 47"W x 36"H (nominal); specify other desired size.

FRP Panel Options

Both Classes of FRP panels feature a unique advanced polymer non-outgassing adhesive, allowing installation on surfaces such as drywall. A specialized seam sealant provides trim-free seams that expand and contract to accommodate temperature-induced dimensional changes without creating cracks or gaps. Finally, a patented surfacing technology seals panels uniformly to enhance durability and prevent particle emission and microbial growth.

Class A BioSafe interior panels are the only FRP wall panels certified to ISO 5 standards for added cleanliness, and FM approved for increased safety and fire hazard protection.

BioSafe FRP Wall Panel Specifications

C-PVC Panel Option

Cleanroom chlorinated polyvinyl chloride (C-PVC) wall panels are tested and certified to meet ISO 5 – 8 cleanliness standards. These compressed panels also offer excellent chemical resistance and prevent particle emission and microbial growth.

Their unique solvent-free silicone adhesive allows installation on wallboard substrate mounted to Terra's steel frame structure, creating a strong, rigid structure. Seams are welded to provide trim-free seams, without cracks or gaps. Optional PVC coving is available for floors and corners to further simplify cleaning (see photo above).
