Decontaminate all materials before exiting. Depending on the material and procedures that will be performed with the material, the IBC may require the following BSL-2+ additional safety precautions: Important:Any work which involves the isolation of or characterization of SARS-CoV-2, the virus which causes the disease COVID-19, must be performed at BSL-3. between computer workstations, desks, or equipment that position staff six feet apart from each other. Its ability to cause disease and the way(s) in which it causes disease (transmissibility and pathogenicity); How much of it is required to cause disease (infectious dose); How many different organisms are susceptible to infection (host range); and. Placement of other furniture (chairs, stools, etc.) Untie the strings behind the head or stretch the ear loops. The guidance below describes how to remove a face covering and replace it with a clean face covering: Depending on the facilitys design or configuration, additional physical barriers, such as a face shield, plexiglass, partition, or plastic barriers, may be needed to achieve social distancing goals. Specific considerations for a BSL-1 laboratory include the following: . Access to the laboratory is restricted when work is being conducted. Biohazardous waste accumulation cages/areas will also be serviced during these days. Revolving darkroom doors, clean room ratings, additional exhaust fume hood systems, stable structure and vibration control, interstitial service plenum with walk-on or structured ceiling deck, shielded space, clean power, and additional piping systems including filtered chilled water typical of wet laboratories are not included in the table. An ADA hood is designed with a sash that opens vertically and horizontally. In addition, facilities should adhere to local policies and procedures as well as all applicable federal, state, and local regulations and public health guidelines. Engineering controls, including facility construction and design elements in the laboratory space; Administrative controls, including specific access, training, and occupational medicine policies; and. BSL-1 labs are used to study infectious agents or toxins not known to consistently cause disease in healthy adult humans or animals. Work which may require BSL-2 facilities with BSL-3 work practices includes but is not limited to, processing of certain clinical samples from COVID-19 patients, performing diagnostic tests which do not involve propagation of the virus, and work with any sample where procedures may produce an aerosol. Suit laboratory Laboratory personnel are required to wear full-body, air-supplied suits, which are the most sophisticated type of PPE. All rights reserved. Spaces between benches, cabinets, and equipment shall be accessible for cleaning and to allow for servicing of equipment. The self-closing laboratory doors are to be able to be opened with a minimum of effort as to allow access and egress for individuals with physical limitations. Separate Laboratory Modules: A Wet Lab space is typically divided into separate laboratory modules that contain individually controlled connections to HVAC, utilities and safety devices. In a teaching laboratory, the desired spacing is 6 feet. Provide employees with accurate information about COVID-19, how it spreads, and the risk of exposure. In general, laboratory spaces have positive pressure relative to other spaces with no return air from the laboratory to the other spaces. Suit laboratory Laboratory personnel are required to wear full-body, air-supplied suits, which are the most sophisticated type of PPE. Over the past 30 years, architects, engineers, facility managers, and researchers have refined the design of typical wet and dry labs to a very high level. Should you have any questions or comments on the WBDG, please feel free to contract our team at wbdg@nibs.org. In addition, the laboratory space is designed to also prevent contamination of other spaces. All personnel shower before exiting the laboratory and go through a series of procedures designed to fully decontaminate them before leaving. Laboratories which use hoods or other larger equipment should be equipped with doorways that The Wet Laboratory space types are typically located within a building specifically designed to house them (see WBDG Research Facilities). The laboratories incorporate all BSL-3 features, as well as, additional safety features. All laboratories should perform site- and activity-specific risk assessments to determine the most appropriate safety measures to implement for particular circumstances. Learn about lab requirements and guidance due to the COVID-19 pandemic. The IBC will review exceptions on a case by case basis. Other engineered safety features include a requirement for entry through two self-closing, interlocked doors, sealed windows, floors and walls, and filtered ventilation systems. Laboratories having a floor area of 200 square feet (18.6 m2) or more need two separate exits. For GSA, the unit costs for Wet Laboratory space types are based on the construction quality and design features in the following table. All portions of the laboratory must be within 75 feet of an exit. Gas/Utility Services: Utility connections in Wet Laboratory space types can include vacuum, pneumatic supply, natural gas, O2 and CO2, and distilled water. in category 210 (Class Laboratory) and space in category 215 (Class Laboratory Service). Wash hands before putting on face coverings and minimize the removal while in the laboratory. The Wet Laboratory s Provide one ADA height (34 in.) While the engineering controls required for BSL-4 cabinet and BSL-4 suit laboratories differ in some respects, the controls are extensive and supplemented by carefully designed procedures and practices in both types of laboratories.
