Product Description

Product Description

Fume hoods are designed to provide personnel protection from toxic or volatile chemicals by continuously shifting airflow away from the user and to the work area. Fume hoods are often the most used piece of equipment in research laboratories and frequently shared by lab personnel.

 

In ordinary times, keeping the work area and operator safe is absolutely essential, but during these extraordinary times, it's fundamental. When it comes to installing and using a fume hood in your laboratory, here are some principle tips and reminders to consider.

It's important to avoid placing the chemical fume hoods opposite from workstations, desks, microscope benches or other areas where personnel spend significant time. As noted above, the reason should be obvious-any incident in the hood could involve or injure anyone seated in front of the hood.

Installation Instructions

Since a smooth entry is vital, placement of the hood in the laboratory requires careful consideration. Layout of the laboratory and location of the chemical fume hood are important for optimal performance and minimal interference.

 

Locate fume hoods away from doorways and exits. The National Fire Protection Association recommends that they be ten feet from any door or exit. The explanation is simple, in that the exit would be blocked should a fire or chemical release occur. Additionally, the constant traffic can potentially disturb the needed smooth flow into the hood. Other factors that can disturb airflow include air supply diffusers, doors and windows, as these could affect the ability of the hood to capture and exhaust contaminants in the way it's designed to.

One final recommendation is to make sure cabinets and equipment do not block or interfere with the fume hood opening or the laboratory's supply or exhaust vents. Having items stored on top of cabinets or in front of hoods or vents significantly disrupts the airflow.

FAQ

 

Why Does Your Lab Need a Fume Hood?

If you work with potentially harmful materials in your laboratory, a fume hood is an essential piece of equipment to keep researchers, employees, teachers or students safe.

While many different types of fume hoods exist, the basic principle behind them all is a work space with one open side that allows fresh air to be drawn into the hood. The moveable glass panel with the open side is called the sash. Even in the closed position, sashes still allow air to enter the fume hood. The air is then released through an exhaust vent or duct.

All work with radioactive material, perchloric acid or other material that could be explosive or corrosive, and chemicals that release noxious fumes should be done inside a fume hood.

Ideally, fume hoods should be located in a part of your lab with low foot traffic to minimize the amount of turbulence in the air that could allow contaminants to escape into the lab. Our Installation Team has had more than twenty years of experience and can help you determine the best place to put your new fume hood.
