Fume hoods are an essential feature of the laboratory that removes harmful vapors and fumes away from the environment and working staff by expelling contaminated air or filtering it before recirculating it. This in turn helps maintain the flow of fresh air into the lab and protects the health of working personnel. Depending on consumer demands a wide range of fume hoods is available. Each fume hood is uniquely designed for a specific purpose. Selecting a fume hood is complex but installing it is also an endeavoring task.
Here are a few steps to keep in mind while installing a fume hood.
Choose an appropriate location
Determining the location of the lab fume hood is primary. Fume hoods should be placed at least 10 feet away from doors and windows. Any kind of air turbulence can impair the hood’s ability to expel contaminated air.
Also, Hoods should be far away from the traffic flow as it would block the hood.
An ideal location would be a well-ventilated area near the source of fumes or chemicals that you are working with. While keeping safety in mind and local rules.
Check the connections
Ducted fume hoods are connected to the building’s HVAC solutions. This facilitates to carry contaminated air from the operator away from the lab and exhaust into the atmosphere. Before proceeding, check the electrical panel or wiring to connect the hood to the electric supply.
Mount the fume hood
Before setting up the fume hood check the sash to ensure it operates seamlessly. The sash must be adjusted in a way that it’s simple to open and close. while still providing a tight seal when closed. Align the fume hood while ensuring it has access to ventilation. Then push back on the hood so it is posing against the wall.
Hire an electrician who knows local codes. Connect the fume hood to the power source.
Seal the hood
It’s time to seal the fume hood after it’s been linked to the building’s wiring and ducts. Seal all cracks and crevices between the fume hood and work surface with an authorized adhesive or caulk to guarantee no contaminated air flows back into the lab.
Finally, replace all of the removed paneling, and your fume hood is complete.
Proper installation is necessary to ensure the fume hood works effectively so that the environment remains clean.
Train the personnel
After installing the fume hood, instruct the workers on how to use it properly, as well as on safety measures and maintenance compliance.
Testing and Certificate
Your fume hood requires a certificate sticker. In case the date of inspection on the sticker was more than a year ago, get the hood examined. Contact a testing service to inspect the hood and certify that it is in good working condition.
A fume hood is an integral part of laboratory resourcing in a contaminant-free environment. To install a fume hood you need adequate knowledge related to fume hood, the process involved, and the technical aspects. Seek advice from professionals for proper installation and smooth operation.

What type of glass would you suggest for fume hoods?
