What risk do auxiliary air fume hoods pose to workers?

• A. They create high airflow noise levels.
• B. They expose workers to high levels of chemicals during use.
• C. They increase the risk of ignition of flammable materials.
• D. They provide insufficient airflow for safety.

Answer: (B)

Auxiliary air fume hoods primarily pose a risk to workers by potentially exposing them to high levels of chemicals during use. These types of hoods are designed to capture vapors, gases, and particulate matter, but if they are not functioning optimally, they may not provide adequate protection. For instance, if the airflow is insufficient or the hood is improperly used, hazardous chemical exposure can occur, which can have serious health implications for workers. While there are other factors to consider with auxiliary air fume hoods, such as noise levels and ignition risks, the primary concern is the ability of the hood to effectively contain and exhaust hazardous fumes. Insufficient airflow or blockage can lead to the buildup of toxic or corrosive substances, putting worker safety at risk. Proper understanding of the hazards associated with chemical exposure is crucial for maintaining a safe laboratory environment.
