How to use a fume hood?

Laboratory Fume Hoods are made to keep lab workers secure when handling dangerous substances. Toxic particles that might lodge in the lungs and have detrimental effects on health are prevented from being inhaled by using air filters.

Before Utilizing a Fume Hood

• Get acquainted with the compounds. You should be aware of any potential safety risks before working with hazardous materials. Read the Safety Data Sheet (SDS) and take the recommended safety measures.

• The first thing to do is make a mental note of the nearest exit, emergency eyewash, and fire extinguisher. Also, make sure that these things are within your reach and have no obstruction in your path in any way.

• Take note of the closest exit, the eyewash station, and the fire extinguisher. Make sure there are no obstructions in the paths to these places.

• Verify the certification sticker on the fume hood. Getting a yearly inspection of the fume hood is recommended. You can check the certification label; it states the average face velocity and the date the hood was last tested. The typical face velocity is between 100 and 120 fpm. Fume hoods for everyday usage are typically adjusted to 115 fpm.

• Verify that the exhaust is functioning correctly. The primary function of a fume hood is to remove dangerous gases and fumes from the area.

How to properly use a Fume Hood

A fume hood should be used for any processes involving the use of volatile substances. Examples of substances that must be employed under a fume hood include flammable solvents, corrosive acids, and bases, combustible or potentially explosive gas concentrations, asphyxiating gases, irritant vapors, or dust, and open sources of volatile radionuclides.

• When utilizing the hood, keep the sash at least 18 inches away from the work area to maximize flow and protect yourself from chemical splashes or explosions. When there is an explosion, the sash serves as a protective screen. The glass is intended to spider rather than shatter. When you aren't using the hood, you should close the sash.

• It’s important to place the chemicals six inches inside the hood because, in case of an emergency, you will have to close the slash quickly. You must make sure that nothing is blocking the area and that only the chemicals that you need are inside the hood. Keeping the chemicals six inches inside the hood will limit the access of any potential fume outside.

• Keep the airflow uninterrupted. Using outside fans close to the fume hood entrance may disrupt airflow, which will reduce the fume hood's efficacy. Additionally, moving quickly in or out of the hood while strolling close to the entrance might have a similar impact.

• Do not put your face inside the fume hood. Your hands should be the only body parts within the fume hood unless you're utilizing a walk-in model. The sash serves as a protective barrier and is used when doing dangerous tasks.

• Put blocks under heavy machinery. By doing so, air will be able to circulate beneath it and the fume hood will be able to function.

Learn the fundamental uses and emergency protocols for a fume hood if you are planning to use one. Keep in mind that specific Laboratory Fume Hoods could need extra precautions taken before, during, or after usage. Design your experiments to expose you to potentially dangerous materials as little as possible, and always search for methods to make them safer.
