BSL Biosafety Levels Cleanrooms ISO 8 ISO 7 ISO 6 ISO 5 ISO 4 BSL 1-877-560-8881 Biosafety Cleanroom Design and Build Printer Friendly (PDF) Biotechnology based remedies are rapidly coming to market to address a vast number of rare diseases and common ailments. Biotech innovations have dramatically increased the number of BSL Biosafety Level cleanrooms or BSL zones within larger cleanroom operations. BSL Protocols are put into place to manage risks related to containment, infection, transmissibility, with the Level depending on the nature of the work conducted, origin of the microbe, agent in question, route of exposure. BSL-1 Cleanroom Design Requirements Biotech cleanroom engineering and construction standards to achieve the required ISO Classification for the application, coupled with BSL-1 requirements standard engineering controls for BSL-1 laboratories and cleanrooms include the requirements outlined below. Biosafety Level 1: Overview Biosafety Level 1 is suitable for work involving well-characterized agents not known to consistently cause disease in immunocompetent adult’s humans and present minimal potential hazard to laboratory personnel and the environment. BSL 1 laboratories are not necessarily separated from the general traffic patterns in the building. Work is typically conducted on open bench tops using standard microbiological practices. Special containment equipment or facility design is not required, but may be used as determined by appropriate risk assessment. Personnel must have specific training in the procedures conducted in the laboratory. Common BSL-1 Considerations for Architectural Finishes Materials of construction and finishes: non-porous, smooth, cleanable, withstand cleaning / sanitization agents, not supporting microbial growth Walls: modular construction optional Ceilings: suspended lay-in style acoustical tile Doors: single & double leaf rapid roll-up seamless door frame Floors: troweled self-leveling epoxy flooring Exterior glazing: optional but not preferred Interior glazing: single or double glaze impact resistant and sealed Air Changes Per Hour (ACPH): 15 minimum BSL-2 Cleanroom Design Requirements Biotech cleanroom engineering and construction standards to achieve the required ISO Classification for the application, coupled with BSL-2 requirements standard engineering controls for BSL-2 laboratories and cleanrooms include the requirements outlined below. Biosafety Level 2: Overview Biosafety Level 2 standards, protocols, and engineering, design, and construction techniques build upon BSL-1. BSL-2 cleanrooms and laboratories commonly handle applications such as equine encephalitis viruses and HIV, as well as Staphylococcus aureus (staph infections). BSL-2 cleanrooms and laboratories are separated from the general traffic patterns in the building. Special containment equipment or facility design is required Personnel must have specific training in the procedures conducted in the BSL-2 cleanroom or laboratory. Personnel are trained to handle pathogenic agents and are supervised by those with advanced training.undefined Biosafety cabinets or other physical containment for all procedures that can generate infectious aerosols or splashes. Autoclave or other method of decontamination for proper disposal of materials or sterilization for re-use. Eyewash station or eyewash safety shower Interlocking doors, and commonly with badge-controlled facility access Extra care is taken to control routes of exposure, including advanced techniques for handling contaminated sharps Immunizations are provided to lab personnel when appropriate Additional PPE, such as face shields may be necessary A lab-specific biosafety manual that outlines the necessary controls and practices for the work performed in that lab is established and well known by the trained team working in the area. Common BSL-2 Considerations for Architectural Finishes Materials of construction and finishes: non-porous, smooth, cleanable, withstand cleaning / sanitization agents, not supporting microbial growth Walls: modular construction Ceilings: modular panel system Doors: single & double leaf sliding seamless door frame Floors: troweled self-leveling epoxy flooring Exterior glazing: not recommended, corridor separating exterior from BSL spaces preferred Interior glazing: single or double glaze impact resistant and sealed Air Changes Per Hour (ACPH): 15 minimum BSL-3 Cleanroom Design Requirements Biotech cleanroom engineering and construction standards to achieve the required ISO Classification for the application, coupled with BSL-3 requirements standard engineering controls for BSL-3 laboratories and cleanrooms include the requirements outlined below. Biosafety Level 3: Overview Biosafety Level 3 is applicable to clinical, diagnostic, teaching, research or production facilities where work is performed with indigenous or exotic agents that may cause serious or potentially lethal disease through the inhalation route of exposure Personnel have specific training in handling pathogenic agents and are supervised by scientists competent in handling infectious agents and associated procedures All procedures involving the manipulation of infectious materials must be conducted within BSCs or other physical containment devices These labs must use controlled or directional air flow to ensure additional safety measures Other safety features include two self-closing or interlocked doors and sealed windows: ceilings, floors, wall surfaces, and filtered ventilation systems Common BSL-3 Considerations for Architectural Finishes Materials of construction and finishes: non-porous, smooth, cleanable, withstand cleaning / sanitization agents, not supporting microbial growth Walls: seamless hard wallboard Ceilings: seamless hard ceiling Doors: single & double leaf bubble tight sliding with inflatable seals seamless door frame Floors: troweled self-leveling epoxy flooring Exterior glazing: not allowed due to hazard Interior glazing: single glaze impact resistant and sealed Air Changes Per Hour (ACPH): 15 minimum BSL-4 Cleanroom Design Requirements Biotech cleanroom engineering and construction standards to achieve the required ISO Classification for the application, coupled with BSL-4 requirements standard engineering controls for BSL-4 laboratories and cleanrooms include the requirements outlined below. Biosafety Level 4: Overview Biosafety Level 4 is required for work with dangerous and exotic agents that pose a high individual risk of aerosol-transmitted laboratory infections and life-threatening disease that is frequently fatal, for which there are no vaccines or treatments, or a related agent with unknown risk of transmission. These labs incorporate all BSL 3 features and occupy safe, isolated zones within a larger building or may be housed in a separate, dedication building. Agents with a close or identical antigenic relationship to agents requiring BSL-4 containment must be handled at this level until sufficient data are obtained either to confirm continued work at this level or re-designate the level. Staff must have specific and thorough training in handling extremely hazardous infectious agents. Two types of BSL-4 Labs: 1. A Cabinet Laboratory-Manipulation of agents must be performed in a Class III BSC 2. A Suit Laboratory-Personnel must wear a positive pressure supplied air protective suit BSL-4 cabinet and suit laboratories have a special engineering and design features to prevent microorganisms from being disseminated into the environment. Common BSL-4 Considerations for Architectural Finishes Materials of construction & finishes: non-porous, smooth, cleanable, withstand cleaning/sanitization agents, not supporting microbial growth Walls: seamless hard wallboard Ceilings: seamless hard ceiling Doors: single leaf bubble tight seamless door frame Floors: troweled self-leveling epoxy flooring Exterior glazing: not allowed due to security, hazard and terrorist threat Interior glazing: single glaze impact resistant and sealed, only to monitor staff and operations Air Changes Per Hour (ACPH): 15 minimum Cleanroom Markets & Applications Biotech & Pharmaceutical Cleanrooms Nanotech & Semiconductor Cleanrooms Cleantech & Renewable Energy University Cleanrooms Government Cleanrooms Latest From AdvanceTEC Latest Blog Post: 8 Design Tips You Need to Consider for Your Cleanroom Understanding environmental factors is an important element when designing and building a cleanroom.
