The lab fume hoods are essential components of modern-day labs all over the world. These lab fume hoods will provide the lab operators with safety and protect them from all forms of hazardous and toxic fumes, gases, and particulate matters. When lab workers inhale harmful fumes, then toxic elements will enter their bloodstreams, particulate matter can be embedded within their lungs and lead to diseases. The lab fume hood will reduce the exposure and contain fumes, a particulate matter which is dispersed when experiments are conducted.
The lab fume hoods have powerful fans which will divert airflow in a chamber with filters or external ductwork that releases the air outside the lab building. Ductless fume hoods will filter the air and then release it back into external rooms. When the fume hoods filter the air, they provide environmental safety as harmful fumes are removed and the air is released inside the room again.
When should you use a lab fume hood?
IT is vital that you should use lab fume hoods when you want to conduct an experiment that has toxic, carcinogenic, odorous, flammable, and dusty materials. This will include chemicals which have the following qualities:
- Acute toxic air – even a mild or short term exposure to such air will cause a lot of organ damages and can even result in fatality.
- Reproductive toxins presence– These forms of toxins will cause massive damage to chromosomes and can harm fetuses.
- Flammable material– health rating with 3 or 4 of the National Fire Protection Association can cause respiratory illness.
- Carcinogenic – may cause cancer in the future. These elements are listed and regulated by the National Toxicology Program or International Research on Cancer
- Odorous elements – These can be hazardous or nonhazardous.
- Light dust elements – This is common when working with any form of hazardous material and can creating irritating dust.
There are certainly other aspects of an experiment that you must consider when you use lab fume hoods. These aspects include the process of the experiment, the chances of gases being released, the complexity and amount of manipulations, how skilled your lab operators are will also be a factor. The experiments need to be designed in such a way as to utilize the lab fume hoods whenever it is necessary.
The lab fume hoods must never be employed when you are using biological agents and highly toxic elements. IF you are working with biological agents that have low and moderate risk pathogens and harmful organisms then you need to use clean rooms in order to prevent any form of contamination. When you are using highly toxic elements, then you will need to use external glove boxes as these will provide more safety to your lab operators.
It is crucial to use lab fume hoods in a proper manner as it will ensure that your lab workers are safe from any form of respiratory disease that can cause them long term harm. Some of the most dangerous elements that a lab fume hood will remove are as follows:
- Ammonia (NH3) -50 ppm- 35 mg/m3 – This can cause Sinusitis, nose irritation, and eye irritation, dangerous injuries, and even death.
- Arsine (C18H14AsCl)-0.05 ppm-0.2 mg/m3 – This can cause confusion, drowsiness, fatigue, headache, muscle cramps, nausea, vomiting, and/or abdominal pain, rapid breathing, red or dark urine, shortness of breath, weakness, jaundice.
- Carbon Monoxide (CO)- 50 ppm -55 mg/m3- This is a Poisonous gas, it can cause central nervous system damage and asphyxiation
- Chlorine (Cl2)-1 ppm-3 mg/m3- Toxic by inhalation, Bronchitis or chronic lung conditions
- Chloroform (CHCl3)-50 ppm -240 mg/m3 – This is a Suspected carcinogen, it can cause impaired liver function, cardiac arrhythmia, nausea, and central nervous system dysfunction
- Fluorine (F2)-0.1 ppm-0.2 mg/m3 – This is a poisonous gas; it may be fatal if inhaled. Vapor extremely irritating. Contact may cause burns to skin and eyes.
- Formaldehyde -H2CO- 0.75 ppm – This can cause Irritation eyes, nose, throat, respiratory system, lacrimation (discharge of tears), cough, wheezing, a potential occupational carcinogen
- Hydrochloric Acid (HCl) – This will cause Coughing, choking, inflammation of the nose, throat, and upper respiratory tract, and in severe cases, pulmonary edema, circulatory system failure, and death.
- Hydrogen Selenide (H2Se)-0.05 ppm-0.2 mg/m3- This is Fatal, extremely dangerous to live.
- Hydrogen Sulfide (H2S)-20 ppm- This will cause Death, permanent injury, affects the nervous system resulting in paralysis of respiratory centers.
A clear panel fume hood will protect lab workers from these types of dangerous elements. You can find top quality clear panel fume hoods online at highly discounted prices. Choose a good lab equipment supplier. Hopefully, the information mentioned in this article will have helped you.
Lab fume hoods are vital for ensuring the safety of the working environment inside labs.
