Laboratory exhaust fume hoods are necessary in all laboratories regardless of the experiments that are being conducted. Every person working in the lab must know they are safe from toxic fumes that may be created during an experiment, and the fume hoods must have a powerful fan that will clear the room in a matter of moments. A fume hood must be installed by a professional, and only special chemical fume hoods can be used in laboratories.
#1: Use The Right Hood
A chemical fume hood is completely different from the hood found in a kitchen, and you must request the right sort of hood before you continue with your installation. A professional installer can help you choose the right hood for your lab, and you must ask the installer where the hood should be placed.
The hood will be attached to a special conduit that leads the gases out of the building, or the hood may be attached to an incinerator that burns off dangerous gases. Special hoods are designed for use with incinerators, and your installer must attach the hood to the incinerator properly. Your lab cannot fill with toxic gases if the hood is in operation, and you can safely dispose of the gases.
#2: Remote Operation
The switch for the hood must be located in the lab, but there must be a separate hood located outside the lab for use by safety personnel. People in the lab may be overcome the fumes, but the hood can be turned on from a remote location. The panel inside the room helps lab workers choose the speed of the fan, the force of the fan and how open the duct is. A small amount of fumes may be disposed of using the lowest settings on the hood, but toxic gases that have built up must be eliminated using the very highest settings on the hood.
#3: How Do You Make Room For The Hood?
The hood you use in your lab must have its own space in the ceiling, and the hood must sit over the most volatile work area in the lab. Perform your most dangerous experiments directly under the hood, and ask your installer if the place where you keep those experiments is a good place for the hood. A wise installer will point you to the right location for the hood, and you may adjust the layout of your lab space accordingly.
#4: How Long Must They Last?
A chemical fume hood will last a very long time if it is cleaned and serviced properly. Every hood must be cleaned properly, and the services must be done on your fume hood every few months. The cleaning for the hood will include a complete adjustment, and there must be a report on the status of the hood. Every person who uses the hoods must have a record of the cleanings, and you should shut down experiments in the lab if the hood is every found to be lacking.
You can keep your laboratory much safer than normal with the use of just one hood, but every sensitive experiment location must have its own hood. The hoods for the lab must be purchased and installed from the same location, and you will benefit from service done by the same technician who did the initial installation. The lab cannot be completely safe without special hoods to pull out toxic gases, and you must consider how your staff will use the hoods when you are in an emergency situation. Proper procedures and equipment will help you run your lab safely and cleanly.
