5 Reasons Why It Is Important To Choose The Right Benchtop Fume Hood For The Lab

Benchtop fume hood provides the same filtration capabilities as ducted hoods but they are easier to install, have lower initial installation costs, and can be highly efficient. They are equipped with numerous advances in technology to improve safety and function. Filter saturation alarms help maintain near-zero chemical emissions in the rotating air and backup safety filters to protect them from filter malfunctions. Low airflow alarms guarantee proper containment of fumes inside the hood. Compared to ducted hoods, benchtop fume hood require very little energy to operate.

The main purpose of the fume hood is to generate and exhaust gases, vapours, and fumes from the area. The fume hood starts this process by pulling in and through the fumes of room air. The air passes into the hood via the sash. The sash can move vertically or horizontally, or a combination of both depending on its size. The sash serves also as a shield between the employee and the inner part of the fume hood. As the airflow makes its way through the centre of the fume hood, it moves the toxic gasses, vapours and fumes into the exhaust area. Slots and baffles are used to control this area, which serve as fume hood exit doors before either the linked ductwork or the fume hood filters are reached.

If the triggers are blocked, block the exhaust path too. But when properly used, the baffles eliminate dead spots or reverse air flows resulting in a loss of containment. After air leaves a fume hood, it is transported via the duct to the atmosphere; the air is filtered and returned to the room on a ductless fume cap.



5 Reasons why it is important to choose the right benchtop fume hood for the lab:

Know what kind of chemicals they use: Knowing the chemicals present in a lab will simplify the selection process. The best approach is to meet representatives from several manufacturers of the benchtop fume hood to do a comprehensive laboratory assessment of the chemicals. The representatives will report on the components in detail and suggest a suitable chemical hood.

Consider where people can put the hood: Initial preparation is important if people expect to put a new chemical fume hood in the lab. People need to consider where they will place the hood. Ventilation of the room and people's movement affects the efficiency of the fume hood. To safely extract the poisonous fumes from the chemicals, therefore, the devices must be placed away from doorways and air conditioning systems.

Consider tracking Airflows: A good fume hood should have an airflow monitoring device and sound an alarm in case there is a limited airflow in and out of the laboratory. An airflow monitor normally alerts users to the degree that it presents a hazard if its velocity goes up. The system should immediately notify the user there is a problem in the hood. Also, choose a device with automatic sash sensors that will close the device after a defined time when they detect any lack of movement.

Choose enough enclosure: People should go for a smoke hood with sufficient enclosure to allow at least five inches of space behind the sash. The equipment should have sufficient space to prevent the chemicals placed inside it from touching the front roof or the air foil. opt for a hood that has open top systems to catch toxic vapours as they deal with a lot of solvents. If people operate the hood with fire-causing chemicals, ensure that the hood they choose has enough room for a fire extinguisher.

Consider costs for the installation: People need to be aware of the costs of installing any benchtop fume hood they choose. Each fume hood has its unique characteristics. This means that the price of purchase and installation varies considerably.

Now, one can easily be familiar with the amazing usage of benchtop fume hoods. To enjoy the service of the same in a good manner it is also necessary for one to select the right benchtop fume hood.

5 Ways To Use Benchtop Fume Hood Efficiently

The Benchtop Fume Hood is fitted with an anti-shattering film tempered glass, centrifugal fan blower, and low-voltage vapour-proof LED lamp. It's a perfect fume-hood for treating flammable or corrosive gasses in the substance testing centre. It is a large platform that can accommodate ovens/furnaces of small to medium scale. The standard lengths of benchtop hoods are 4 ft to 10 ft. It can be made to custom sizes, however, depending on user requirements. The hood exteriors are made with GI steel sheet, our hoods are available as standard in two sash styles combinations-vertical and horizontal.

User can select from baffles, cover, and workstations. As per customer specifications and DIN standards, the hoods are fitted with appropriate lab utility service fittings and internal piping. Larger-size hoods are designed for excellent performance with two exhaust collars. Benchtop hood workstations are mounted to a solid base frame, with precisely 900 mm from the floor making it more comfortable for the end-user to work in a standing position. The bench-top fume hood creates a working space that minimizes a dangerous situation's chance of damage. 

It is obvious that no fume hood, however well built, will provide sufficient containment unless the use is made of good laboratory practices. The secret is to proper planning and preparation. The hood consumer should know the hood's Standard Operating Procedure and should design experiments to preserve the SOP if hazardous materials should be released. Look for improvements to procedures that enhance health and reduce environmental losses. Establish a mechanism for assessing research proposals for future emissions in advance, and explore ways to reduce them. The amount of protection a fume hood offers can be affected by the way the fume hood is used. The 5 accurate ways to use Benchtop Fume Hood efficiently are bellowed: 

Distance is needed for safety- Ensure the exhaust works until work starts. Find out the obstructions on the baffles. When an airflow sensor is attached to the hood, check the status of the sensor. Even while operating, be alert to airflow shifts. Keep face outside the hood plane while using the fume hood. During hazardous work using the sash for partial safety. Work at least 6 back from the hood's nose. 

Equipment needed for protection- A line on the top of the bench is a successful recall. Using correct personal safety gear, such as gloves and splash goggles. This increases protection in the event of major spills, run-away reactions or explosions. Place the Lab equipment on blocks when using large machinery inside the hood, to allow air to flow under it when secure and practical.

How airflow destruction reduces the hood performance- Do not make fast movements in or out of the hood, use fans or instantly walk through the hood gap. This will result in airflow disruptions that reduce the hood's performance. Where possible, replace with less dangerous or less volatile chemicals. The hood should be kept closed, except during set-up of the apparatus or when working inside the hood is needed.

Where to keep sash- To optimize the efficiency of the hood keep the hood sash closed as much as possible. Keep the sash closed to optimize energy efficiency when not in use. If the output is suspected, or an airflow warning is activated, end-use and fully close the sash and do not remove sash or sash panels from the hood except when necessary for the set-up of appliances.

When it is needed when to remove or place sash or panel- Sometimes remove sash or panels in the hood before working. If flammable liquids or gases are present, do not place. There are no permanent electrical receptacles permitted within the hood and there is a risk of explosion, implosion or eruption, using an adequate barricade.

5 Steps for Testing and Maintenance of Benchtop Fume Hoods

These devices are designed with transparent sashes for optimum chemical resistance, which can slide horizontally or vertically into position and enable high visibility at work. Many safety features apply to a standard fume hood. Often they're a big piece of enclosed equipment that creates work area. They are leak-proof which ensures that even with heavy daily use and corrosive spills, their enclosures do not corrode. The chemical fume hoods circulate and filter the air to remove the vapours that may have been formed. Such benchtop hoods are put on a flat and stable surface, which people can easily operate on. By using the sash to change the front gap, ventilation can be balanced across the hood to the point where contaminant capture is maximised. Each hood has its optimum sash setup. When operating in the hood, the sash should be left in this position, and fully closed when the hood is not in use.

The sash can be opened for installation of Lab equipment absolutely, but must return to the best conditions before contaminants are generated in the hood.

One of the most essential things is to do the maintenance and testing of Benchtop Fume hood so that one can bring it in use for a long time without any obstruction. For the same one can go through the 5 important ways maintenance and testing of Benchtop Fume Hood that is being given below:

Ensure the sufficient face velocities- Before each use; hoods should be tested by the user to ensure sufficient face velocities because the fume hood does not have sufficient flow levels for the necessary work and lack of unnecessary turbulence. Switch off all services and accessories and lower the sash completely in case of exhaust system failure when using a hood. Leave the area right away.

Accreditation is important for the work safely- Fume hoods should be accredited to ensure they work safely, at least annually. Typical tests include measurements of the face velocity, checks and containment of the tracer gas. Tracer gas containment checks are especially important because studies have shown that face velocity is not a reasonable indicator of leakage of the fume hood. Fume hoods are among the most critical tools used and abused for the monitoring of hazards.

Protection from harmful exposure- Consumers should recognize that the combined use of safety glasses, protective gloves, laboratory smocks, good practices and smoke hoods are very critical elements in shielding us from potentially harmful exposure. Always remember the person most likely to get hurt is the user of the hood. All laboratory occupants can also be affected by the escape from noxious material into the laboratory.

How it design to shield- Fume hoods only cover users when properly used and when properly run. A fume hood is designed to shield the occupants of users and rooms from exposure to vapours, aerosols, hazardous chemicals, odorous substances, and other harmful substances. A secondary purpose when dealing with potentially explosive or high clear reactive materials is to serve as a defensive shield.

What to do when the repair is needed- EH&S performs a practical performance test to ensure that hoods work around every 18 months, as needed. Usually, the performance check involves an assessment of a VAV's face velocity, tone, storage, monitoring capacity and tracking ability. Also notice any observed power, sash, baffles, plumbing, lighting, or corrosion issues. When a hood fails an inspection, they will need to be withdrawn from service before it is fixed. When repair is needed, EH&S will inform the researchers and post a Do Not Use sign. After completion of repairs by UW Facilities, EH&S will reproof the hood and bring it back into operation.
