Fume hoods are one of the most reliable and essential pieces of equipment in your lab. Whether you’re working at a school lab or an industrial setting, a chemical fume hood can turn a catastrophic accident into a minor occurrence. This will show you the purpose of fume hoods, safety tips, and overall information you should know about this essential equipment.
Fume Hoods, also known as fume closets or fume cupboards are designed with the view of protecting people and property from toxic fumes. Toxic chemicals used in the laboratories give rise to gases and fumes that harm both people and the environment. These fumes need to be cleared away immediately to ensure the safety of the people working in such environment, necessitating the use of fume hoods. Though all fume hoods follow the same basic working and design principle, only chemical fume hoods should be used for labs.
The operations in a laboratory setup require different types of furniture that range from heavy duty workbenches, utility cards and lab cabinets to laminar flow workstations and chemical fume hoods. The air has a high chance of becoming polluted as it is not unusual for different types of experiments and industrial work to release toxic chemical vapors, aerosols, and suspended particles. Thus, it is important to keep the lab environment as clean as possible, and a chemical fume hood contributes to this purpose.
A chemical fume hood is basically enclosedequipmentthat is designed to draw air inward for filtration purposes. The main function of the exhaust is to control the presence of hazardous substances in the air by drawing in air with the help of mechanical ventilation.
Experiments conducted in the laboratory often require highly volatile chemicals, strong acids, and bases.Chemical fume hoodshave gained popularity rapidly in the industrial and research space because of their ability to properly dispose of harmful gases released during experiments. The term “fume hood” itself signifies an enclosed device that has the capability of drawing air inward with the help of mechanical ventilation.
Key Points to Understanding Which Laboratory Hood is Right for You
Industrial hoods, like laboratory fume hoods and horizontal laminar flow hoods, permit safe handling of hazardous materials and prevent contamination of highly sensitive materials. They are critical workspaces for protecting workers, protecting products, and protecting the environment. Each type of hood has a particular use for which it is best suited and it is important to know when to use each.
Types of Hoods
There are two main types of hoods,exhaust fume hoodsand laminar flow hoods. A few key points can help you understand the differences between them.
A laboratory is a building where experiments are conducted. There are many kinds of laboratories, and each type is used for performing a particular type of tests. The two major types are the chemistry lab and biology labs. These chemistry labs involve experiments that use toxic substances and thus care should be taken during the performance to prevent accidents. In a biology lab, most tests aren’t as toxic as in chemistry labs. However, care should also be taken to avoid wastefulness and ensure that the safety of the user is assured.
Alaboratory fume hoodis an enclosure that is built inside a chemistry lab for conducting experiments that release toxic chemicals. A fume hood is also used to store volatile compounds that can be harmful to the environment. A laminar flow hood, on the other hand, is also an enclosure built mostly in a biological lab for conducting of experiments that involve delicate microorganisms. It is used to create a sterile environment for doing biological experiments. It is also called a biosafety cabinet.
Laboratory fume hoodsandlaminar flow hoodsare types of specialized laboratory equipment designed to safely handle different types of hazards. Also referred to asclean benches,laminar flow benches, orbiosafety cabinets, these containment devices often appear similar and all use directed airflow to provide a clean and sterile work environment. Despite these similarities, there are key differences in the level of protection provided and suitability for different laboratory tasks.
Fumes hoods are essential elements, especially in an individual’s workspace. People working in places such as, in laboratories and factories can risk exposure to hazardous environment. This is especially if a facility does not have lab fume hood for protections. A facility is best with a fume extraction system, it is, therefore, necessary that one, as a physician, should consider purchasing one. This is primarily to ensure the occupant’s safety, healthiness, and productivity. Choosing efficient fume hoods can be overwhelming, but for some reasons, it is better to consider few tips before purchasing one.Fumes hoods are essential elements, especially in an individual’s workspace.

In any laboratory, employers should take the necessary measures to protect the occupants from dangerous chemical contaminants. A fume extraction system is one of the most important safety mechanisms every laboratory should have. The system works to minimize a person’s exposure to chemicals and particles that are potentially hazardous. Unfortunately,choosing the right fume hoodis a common challenge to many. Here is what we recommend.
Laboratory workers are often working in confined spaces where certain chemicals and/or fumes can be dangerous, even lethal. A qualityexhaust fume hoodcan be the first line of defense when it comes to protecting these employees from silent, but deadly, toxins. These hazards include:
- Inhalation of harmful vapors
- Fires or explosions
- Chemical or thermal burns
- Chemical absorption
Understanding how a hood functions in a protectionary manner means understanding the basics of lab fume hood construction.
