2023
Robert M. Rioux & William A. Elliott, Pennsylvania State University, University Park, PA Fume hoods and laminar flow cabinets are engineering controls that operate under similar principles. Both use a constant flow of air to prevent contamination of the laboratory environment and its inhabitants. Fume hoods prevent hazardous substances from exiting the hood workspace, whereas laminar flow cabinets prevent contaminants from entering the cabinet workspace. Fume hoods are ventilation systems...

Robert M. Rioux & Suprita Jharimune, Pennsylvania State University, University Park, PA Among the many hazards present in the laboratory, electrical hazards are one of the most common we must be cognizant of since most of the laboratory equipment we use requires electricity for operation. Improper handling or operation of electrical devices might lead to electric shock with the potential risk of injury or even death. Electric sparks can lead to fire or explosion (since many flammable...

Performing viral assays in a BSL-4 laboratory is more involved compared to work in a BSL-2 laboratory due to required additional safety precautions. Here, we present an overview of practices and procedures used inside a BSL-4 laboratory illustrating proper Class II biosafety cabinet usage, waste management/disposal, and sample removal.

Surveying near highways, rough terrain, or power lines involves significant risks. Working along highways is particularly dangerous and requires the use of warning signs and flagmen. It is safest to avoid working directly on roads and use offsets whenever possible. When highway work is unavoidable, it must follow all safety guidelines. Surveyors should wear bright clothing, such as orange reflective vests, to ensure visibility to motorists, coworkers, and hunters. In construction zones, wearing...

The protocols describe two in vitro developmental toxicity test systems (UKK and UKN1) based on human embryonic stem cells and transcriptome studies. The test systems predict human developmental toxicity hazard, and may contribute to reduce animal studies, costs and the time required for chemical safety testing.
FAQs
Directional airflow moves air into the cabinet, helping keep potentially contaminated air from escaping into the laboratory. The incoming air then passes through high-efficiency particulate air filtration, which captures airborne particles before filtered air is exhausted or recirculated according to the cabinet design. This coordinated movement and filtration supports personnel, environmental, and sample protection during biological work.
Cabinet designs can differ in how they provide a clean work area and how filtered air is handled. Some arrangements emphasize protection of samples through cleaner working conditions, while others also address exhaust of filtered air. Selecting a design therefore requires matching the cabinet’s protection characteristics to the biological materials, procedures, and laboratory risks involved.
A BSC helps reduce three connected risks: personnel exposure to potentially hazardous biological materials, release of biohazardous particles into the surrounding environment, and contamination of samples during handling. Its airflow and filtration systems support these protections, but the outcome also depends on appropriate operating practices. The cabinet is therefore one component of a broader laboratory biosafety approach.
Correct selection and certification help confirm that a BSC is appropriate for its intended laboratory role and functioning as expected. Appropriate practices during use are equally important because airflow and filtration cannot replace careful biological handling. Together, suitable equipment, certification, and disciplined operation reduce exposure and cross-contamination risks in procedures involving cultures or potentially infectious specimens.
A sound workflow begins by selecting a cabinet suited to the biological materials and protection needs, followed by appropriate certification before use. Researchers then conduct the planned work using practices that preserve the cabinet’s protective airflow and support aseptic handling. This workflow is relevant to cell culture, microbiological procedures, and work with infectious or biohazardous specimens.
These cabinets are useful when laboratory work must limit exposure while also reducing contamination of cultures or specimens. In aseptic cell culture, the cleaner work area supports handling conditions that protect samples. Microbiological procedures and work involving infectious or biohazardous specimens additionally benefit from the cabinet’s role in reducing personnel and environmental exposure during manipulation.
Appropriate use can reduce the likelihood of airborne exposure, environmental release, and cross-contamination during biological procedures. It may also provide a cleaner workspace for sample handling, depending on cabinet design. These outcomes are not automatic: researchers must select and certify the equipment correctly and combine its engineered protections with suitable laboratory biosafety practices.
