What is the fume hood used for in a lab?
The laboratory chemical fume hood is the most common local exhaust ventilation system used in laboratories and is the primary method used to control inhalation exposures to hazardous substances. When used properly, fume hoods offer a significant degree of protection for the user.
Do you need to conduct all labs under a fume hood?
It is advisable to use a laboratory hood when working with all hazardous substances. In addition, a laboratory hood or other suitable containment device must be used for all work with “particularly hazardous substances.”
What are the types of fume hood?
Different Types Of Fume Hoods
- Bench-top Fume Hood. A bench-top fume hood is a hood that sits on a work surface approximately 36” above the floor.
- Floor-mounted Fume Hood.
- Double-faced Fume Hood.
- Portable Fume Hood.
What is a fume hood and how should it be used?
Fume hoods are designed to keep laboratory professionals safe while working with hazardous materials. They filter the air to prevent the inhalation of toxic particles that can lodge in the lungs and cause serious health implications.
Which of the following should be checked prior to using a fume hood?
Follow proper safety fume practices 1. Ensure the fume hood is labeled with a certification date of less than one-year prior. Verify sufficient inward airflow before using a hood by checking the hood’s airflow indicator.
What is the difference between fume hood and Biosafety Cabinet?
A chemical fume hood protects the user while a biosafety cabinet protects the user, the environment, and the material. Biosafety cabinets have high-efficiency particulate air (HEPA) filters while chemical fume hoods do not.
When should you perform work under the fume hood?
Fume hoods should be used when working with toxic compounds or compounds with a boiling point below 120°C. Fume hoods, or other effective local ventilation, must be provided and used when the materials used will exceed exposure limits in the laboratory.
How often do fume hoods need to be inspected?
For fume hoods, they are primarily concerned with airflow at the face of the hood, monitoring, maintenance, and exhaust. OSHA indicates that the quality and quantity of ventilation should be inspected at installation, then regularly monitored at least every three months.
What is the lab desk with fume hoods called?
Many research and animal laboratories use containment devices to keep the user separated from the hazards they are working with. These devices are often referred to by many different names including cell culture hood, tissue culture hood, laminar flow hood, PCR hood, clean bench, or biosafety cabinet.
