Which of the following statements is true about fume hoods that use filtration?

Fume hoods that utilize filtration are not approved for use in New York City due to safety and regulatory standards set forth by the FDNY and other health and safety organizations. The design and function of filtration systems can lead to limitations in effectively controlling hazardous fumes and vapors, which may pose risks in laboratory environments. Insufficient removal of these hazards could result in exposure to harmful substances, making it essential for laboratories to utilize fume hoods that achieve a higher standard of ventilation and safety. Consequently, the regulatory framework has determined that non-filtered, ducted hoods are preferable for compliance with safety protocols and recommendations, ensuring optimal protection for laboratory personnel.
