Use the Laboratory fume hood effectively

An essential role has played by fume hoods and keeping technicians safe from all sorts of harmful chemicals by offering the best ventilation system. These bench fume hoods are best at controlling and absorbing any kind of substance that may hazardous for anyone such as fumes, gasses, dust, vapors, and aerosol. When a chemical reaction occurs then it will act as a barrier within the lab.

On the flip side, technicians as well as workers need to use it in a way that can work effectively and accurately to let get the whole benefits related to protective measures.
Thus, we are providing to make sure that laboratory benchtop fume hood provides utmost protection against toxic fumes, dangerous reactions as well as chemical spills.

Minimize Air Disturbances

The effectiveness of a fume hood can decrease airflow disturbances. That is the reason that it is important to find out the suitable size for the hood is necessary for maintaining the good order of working. After a fume hood is installed, then place it where it can avoid crosscurrents. Many things can lead to result in crosscurrents such as pedestrian traffic, windows, exterior fans, the opening and closing of doors, and windows.

To make sure the maximum containment, it starts avoiding the area of high-traffic so the worker starts moving around the hood. An air disturbance may create by avoiding the quick movement from in and out of the hood.

Make sure that Exhaust is working properly

Before beginning their work in the lab, the technicians make sure that the exhaust is working properly. The main job of a benchtop fume hoods is exhausting fumes, so if this part is not working properly then there may be some issues in the whole operation.

Check the baffles entirely when ensuring that the exhaust is working. Such parts of the ventilation system are movable partitions that create openings in the back of the hood. It is helpful to keep the airflow uniform that increases efficiency. Check out any obstructions that may hamper the airflow.

Airflow monitor is also included in the hood and regularly check the status. Making sure that it is properly functioning will enable you to better examine any suspected changes in the process of airflow.

Practice Good Procedures

In equipment that has an amazing feature of exceptional hood design only provides high efficiency if the equipment is used effectively. The key is to do proper operating procedures. A set of instructions as well as procedures by the manufacturers will come along with each kind of fume hood. On the flip side, some instances of good lab benchtop fume hood procedures comprising the following:

• If there is any large apparatus on the inner area of the hood, then put blocks under the equipment so that air can flow below it.
• Keep the hood closed if you are not working in the hood or setting up any apparatus.
• Whenever it is possible to keep the hood sash closed to increase the performance. If there is any power outage happens, then lesser the hood sash to within an inch. So, it creates a chimney effect to let the airflow.
• You need to be aware of while dealing with some materials such as paper products, aluminum foil, and chemical wipes. These are light in weight and can easily suck into the hood and may impede airflow.
• Utilize the sliding sash barrier if you are using a benchtop fume hood. This one is good for protection and allows you to keep your face aside from the work area.

Prioritize Housekeeping As Well As Maintenance

It is important to have proper housekeeping as well as up-to-date maintenance that is necessary to make sure that the lab fume hood is working properly and providing high performance. Here are some housekeeping and maintenance procedures that you need to implement involve:

• Never store items like chemicals in the hood. They can block the airflow and also interfere with containment too. It is recommended to keep fifty percent of the workplace clear all the time.
• Store the harmful chemicals in the approved safety cabinets. If there is a need for harmful chemicals, then take a small portion of it in the hood. Bio-safety cabinets are designed with a motive of proffering protection against biological material exposure and also serve various functions. It is vital to use the right cabinet for a definite chemical or biological material.
• You need to check the fume filters if you are using the ductless fume hoods to ensure that they are clean or require to be replaced. To remove hazardous fumes as well as particles from the lab, these clean and carbon filters play a significant role.

5 Tips on How to Reduce the Risk and Remove Harmful Chemicals Using Benchtop Fume Hoods

Continuous laboratory work requires adequate safety conditions to protect them against any hazardous tasks. Fume Hoods are designed especially to limit the exposure of laboratory toxic fumes, vapours, or dust. Benchtop fume hoods also ensure safe working conditions. These devices are built with transparent sashes for optimum resistance to chemicals, which can glide vertically or horizontally and have high working visibility. Some 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 means that even with heavy routine usage and corrosive spills, their enclosures will not corrode. The chemical fume hoods circulate and filter the air to eliminate the vapours that may have been produced.

These benchtop fume hoods are placed in a flat and stable surface enabling the consumer to work on them without any problem. Bench Top Fume Hood Fume-hoods extract air from the rooms in which they are installed. If the fume hood is located in a small room or a large number of fume-hoods may require an additional supply of air, other than normal ventilation in the room, this extra air is known as Make-up Air. This can cause laboratory fumes to escape. Any type of fume hood is designed to protect the laboratory workers when performing hazardous experiments and procedures. These devices protect the user from the inhalation of toxic gasses, protect the product or experiment as well as the environment. These benchtop fume hoods have some secondary options; for example, protection against fires, containment of spills and other required functions for the work taking place within the device.

5 Types of Laboratory Fume Hoods and its Properties

A traditional laboratory fume hoods have a box with a movable sash window-like structure.  To ensure full protection, the fume hoods should be properly sited. Due to pedestrian flow, doors and supply air diffusers locate hoods to prevent crosscurrents at the hood nose. Sufficient laboratory supply air must be available to allow hoods to work at their required face velocities. The hood works by maintaining a fairly negative pressure within the hood to prevent any contaminant from escaping while at a constant pace drawing air through the hood opening. A suitable hood face velocity is of interest for the safe and efficient function of a laboratory fume hood. While excessive face velocities can often lead to friction and reduced containment, the hood's efficiency can also be compromised by insufficient speeds. Overall, the face velocity of a hood is recommended to vary between 0.3 m / s (60 fpm) and 0.5 m / s (100 fpm), but it is necessary to test the face velocity recommendation with local safety legislation before using the fume hoods. Most hoods are usually designed for a minimum face velocity at full sash opening; but as a means to save energy, some hoods design the hood's minimum face velocity at the half-sash opening, producing new low-flow laboratory fume hoods, which are now on market.

Although there is various type of Laboratory fume hoods,  5 of them are renowned among the user due to their different properties. Let’s have a look upon the same:

Bench-top Fume Hood - A fume hood at the bench-top is normally mounted on a bench-top or above a storage cabinet. Bench-top hoods are used for a wide variety of chemical procedures that require small to moderate quantities of low to high toxic materials. Benchtop Fume Hoods have efficient containment and emissions of low particulate mass gases, vapor, mists, fumes, and other aerosols. 

Distillation Fume Hood- A distillation hood is defined by a low height of the work desk, which results in the operator having a wide working height. It allows for the installation and positioning of large distillation equipment in the workroom. Otherwise, it has features similar to those of a regular fume hood. The hood is unable to withstand fires since the sash is fully sealed. If there is an explosion hazard, the user should have adequate strength to deflect or contain the anchored barriers, shields or enclosures.

Perchloric Acid Fume Hood- The perchloric acid reacts with organic materials violently. The perchloric fume hoods also require built-in water wash-down systems to prevent salt deposits from being perchlorinated. Both treatments use perchloric acid must be limited to a perchloric fume hood to avoid adverse interactions with certain chemical substances. Perchloric acid should not be used with a traditional fume hood. Perchloric acid vapours may settle to ductwork, resulting in perchlorate crystals being deposited. 

To Radioisotope Fume Hood- Radioisotope fume hoods are designed primarily to protect users from hazardous materials. We have specially designed workstations to withstand the weight of lead shielding tiles, and may also have lead-laced sashes. For decontamination purposes, the interiors are made of stainless steel with polished corners. 

Floor Mounted Fume Hood- For applications involving large Lab equipment, floor-mounted fume hoods are used. These hoods, as the name implies, are mounted on the floor, without any work surface. It allows the movement of materials and machinery into and out of the hood. Mounted floor hoods are often referred to as walk-in fume hoods, although incorrectly.

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. 

Thus, everyone can be similar about the best 5 ways to use Benchtop Fume Hood effectively along with the safety without any efforts and by this, the user can be safe from various dangerous gases which automatically attract the customer/users toward the particular agency.
