Best practices for positioning a class II, type A2 biosafety cabinet
19 Jun 2025This expert-designed infographic provides essential guidance for scientists, laboratory managers, and pharmacy professionals on the correct placement of Class II, Type A2 biosafety cabinets (BSCs) within laboratory or cleanroom environments. It outlines how improper positioning—particularly near disruptive air currents—can compromise airflow integrity, increasing the risk of contamination.
The infographic details how high-velocity cross-drafts may interfere with the cabinet’s inflow and exhaust dynamics, especially at the vulnerable exhaust HEPA filter area. Such disturbances can overwhelm the cabinet’s protective air barrier, reducing operational safety and compromising sample integrity.
Additionally, the resource addresses critical exhaust considerations for cabinets used in procedures involving trace amounts of radionuclides or small quantities of non-flammable, non-explosive, volatile, toxic chemicals. Guidance is provided on the role of properly functioning canopy exhaust systems in maintaining compliance and ensuring safe handling.
