Chemicals in labs can sometimes be harmful to the people who work there. Because of this, a laboratory needs special equipment, like a fume hood, to keep bad things from happening. A fume hood is a device that keeps the air temperature stable and protects highly acidic chemicals or chemical solutions. There are many good things about having a fume hood. But what is a fume hood? How is it taken care of? Look at the review below.
What’s the function of a fume hood?
Those of you who are new to working in laboratories probably don’t know what the fume hood is for. The main job of the fume hood is to move dangerous chemicals, especially those with a lot of acids, to a place where the risks are less. The process of evaporation is how to cut down on it.
The fume hood is not only used to move chemical reactions from one place to another but also to store chemicals. In this case, the chemicals are either liquids, solutions, or solids that are very acidic. With the fume hood, people working in the lab can do their jobs safely and in comfort. Because it is not unusual for chemicals with a lot of acids to be dangerous. In fact, when some chemicals mix, they can cause explosions.
Different kinds of fume hoods and their parts
Based on how they work, fume hoods can be either ducting or ductless. In reality, they both work the same way. The air that comes in through the front of the cabinet (the door in this case) will be pushed through a blower to the filter material. Another part that is no less important is the lighting equipment consisting of fluorescent lamps. Usually, the door is made of strong, long-lasting materials like special glass or acrylic.
In the past, fume hoods were made of wood with epoxy powder and coated plates. But as technology changes, the shape of the fume hood will change again and again. With a special glass on the front. On the inside, fiberglass-reinforced polyester (FRP), stainless steel, and other special materials are used to make the fume hood.
The fume hood’s front can be opened and changed as needed. It’s possible that this will cause the air in the room to mix with the air in the lab. To fix this, the next step is to move air from a dangerous spot to a safer one.
How to use a fume hood:
There are a few things you need to watch out for when using a fume hood. Taking into account that the fume hood can be dangerous if it is not taken care of properly. Especially by people who work in the lab. When you use a fume hood, you need to think about the following:
First, pay close attention to how the air moves. To keep the fume hood working well, it is very important to let air flow through it. You can check the air circulation every now and then. If any damage occurs, you should immediately repair it and the materials used in the fume hood are chemical-resistant.
The second thing is that you should also pay attention to the chemical parts. Even more so when choosing this material for the fume hood. Make sure the parts can handle organic chemicals, chemicals with corrosive properties like acids and bases, and chemical reactions that can cause explosions.
