Assume a research laboratory specializing in chemical synthesis is working on a high-priority project involving volatile and toxic chemicals. During an intense experiment, the team noticed that the fume hood's sash had been left partially open.
As they continue their work, an unexpected power surge causes the hood’s airflow monitor to malfunction, resulting in fluctuating face velocity. What immediate actions should the team take to ensure their safety and contain the potential chemical exposure?
This inherent risk makes understanding and practicing laboratory safety critical to preventing accidents and minimizing exposure. The "Laboratory Safety: Exposure Prevention and Response" course is designed to equip laboratory personnel with the knowledge and skills necessary to safely manage these hazards, ensuring a safe and compliant working environment.
Understanding how to correctly operate fume hoods and prevent potential exposure risks, are very important for laboratory workers. This will help implement best practices that minimize the release of hazardous substances.
In addition to prevention techniques, the course covers essential response protocols for incidents where exposure occurs. From identifying signs of fume hood malfunction to executing emergency procedures, this training ensures participants are prepared to act swiftly and effectively. The course also emphasizes the importance of personal protective equipment and other safety measures that complement the protective capabilities of fume hoods.
Understanding regulatory requirements is another key component of this course. Participants will gain insight into relevant OSHA and ANSI standards, ensuring that they not only maintain personal safety but also uphold compliance with federal regulations.
Whether you are new to the lab or a professional, laboratory safety with exposure prevention and response will enhance your ability to protect yourself and others from the risks associated with hazardous materials, creating a safer work environment for all.

What are OSHA's fume hood face velocity requirements?
Fume hoods shall be balanced with an inward flow, to a minimum of 100 feet per minute face velocity across the opening, with a minimum capture velocity of 50 fpm at any point.
Where do laboratory fume hoods vent to?
Every fume hood needs a blower, and it is often misconceived that a blower comes attached to a fume hood. Nowadays, fume hoods are integrated with exhaust fans attached to a building's exhaust system.
What is the ideal placement of a laboratory fume hood crucial for its effective operation?
To ensure effectiveness, the hood must be placed close to the emission source. The maximum distance from the emission source should not exceed 1.5 times the diameter of the duct.
How often should fume hoods be inspected and maintained?
Generally, EH&S performs a functional performance test to ensure hoods perform as required about every 18 months.
What steps should be taken if there is a spill inside the fume hood?
Many issues can be addressed at the local level. For concerns such as hazardous chemical spillage, contact your EPA Regional Office.
