How often should the face velocity of safety cabinets be checked?

The face velocity of safety cabinets should typically be checked every month to ensure that the cabinet is functioning correctly and providing adequate protection from airborne contaminants. Regular monthly checks help maintain the performance standards necessary for safety in the laboratory environment. This frequency allows for the timely identification of potential issues, such as diminished airflow or filter performance, which are critical for the safety of personnel working with biohazardous materials.

While more frequent checks, such as daily or weekly, are beneficial in high-use environments to ensure immediate safety, the monthly schedule is widely accepted as sufficient for routine monitoring without leading to unnecessary disruptions or resource allocation. Yearly checks, on the other hand, do not provide enough oversight for maintaining safety standards in actively used facilities.
