Handling and storage of chemicals in a laboratory

Handling and storage of chemicals in a

laboratory 

Proper handling and storage of chemicals and reagents is necessary to prevent hazards. Chemicals are stored according to their physical and chemical properties.




Types of chemicals


1. Flammable Chemicals - eg :- Acetone, Ether, Xylene, Alcohol

2. Corrosive chemicals - eg :- Concentrated Acids, Alkalies, phenol etc

3. Oxidising Chemicals - eg :- Potassium dichromate, Chromic acid, Chlorites etc. 

4. Explosive Chemicals - eg :- Picric Acid.

5. Radioactive chemicals- eg :- I 125 , I 131 , H3

6. Carcinogenic chemicals-eg :- Benzidine, O- toluidine, Selenite, etc 

7. Toxic Chemicals -eg :- Potassium Cyanide


Handling and Storage of chemicals 

1. Label the chemicals with hazard symbol, simple instruction for use, strength and Expiry date (it is mandatory for manufacturers).

2. Flammable chemicals are stored in fire proof metal containers at ground level in a cool dry place and always handle them away from direct flame.

3. Corrosive chemicals are stored in amber coloured bottles at ground level.

4. Explosive chemicals are never left in dry state. 5. Radioactive chemicals are handled by properly trained persons only

6. Carcinogenic chemicals are stored in closed container. Exposure to such chemicals should be kept minimum

7. Highly toxic chemicals like Potassium cyanide are kept locked in cupboards and proper documentation is made in stock register. 

8. Do not open flammable chemicals near flame 

9. Do not add water to acid

10. Avoid mouth pipetting.

Why is the number of diabetic patients increasing in today's situation?

  Why is the number of diabetic patients increasing in today's situation? The increasing prevalence of diabetes in recent years can be attributed to several factors. While it is important to note that this response is based on information available up until September 2021, it provides a comprehensive understanding of the reasons behind the high number of diabetic patients. 1. Sedentary Lifestyle: The modern lifestyle has become increasingly sedentary due to technological advancements, automation, and a shift toward desk jobs. Lack of physical activity has led to a rise in obesity rates, which is a significant risk factor for developing type 2 diabetes. 2. Unhealthy Diets: The consumption of unhealthy diets high in processed foods, refined sugars, unhealthy fats, and low in fruits and vegetables has become more prevalent. These dietary habits contribute to obesity and increase the risk of developing diabetes. 3. Obesity Epidemic: Obesity has reached epidemic proportions globally. Ex...

CHEMICAL METHODS OF DISINFECTION

Image
 CHEMICAL METHODS OF DISINFECTION  Disinfectants are those chemicals that destroy pathogenic bacteria from inanimate surfaces. Different disinfectants have different target ranges. Some chemical have very narrow spectrum of activity and some have very wide. Those chemicals that can be safely applied over skin and mucus membranes are called antiseptics. Bacteriostatic chemicals are those inhibit multiplication of bacteria without killing them. Bactericidal is that chemical that can kill or inactivate bacteria. Mode of action of various Chemical Disinfectants include. Protein coagulation, disruption of cell membrane, enzyme damage etc.  Different chemicals used as disinfectants   ALCOHOLS : E.g.: Ethyl alcohol, isopropyl alcohol and methyl alcohol.70% ethyl alcohol (spirit) is used as antiseptic on skin.  ALDEHYDES E.g.: Formaldehyde, and Glutaraldehyde 40% Formaldehyde (formalin) is used for surface disinfection and fumigation operation theatres, biological...

Rheumatoid Factor Test

                                                   Rheumatoid Factor Test The rheumatoid factor (RF) test is an important blood test that is used to help diagnose rheumatoid arthritis (RA) and to differentiate it from other forms of arthritis. RF is an antibody that is produced by the immune system in response to inflammation and tissue damage in the joints.   While RF can be found in the blood of some people without RA, it is present in the majority of people with the disease. Therefore, the presence of RF in the blood, along with other clinical and laboratory findings, can be used to make a diagnosis of RA.   It's important to note, however, that a negative RF test does not rule out RA, as up to 30% of people with RA have a negative RF result. In addition, a positive RF test can also be seen in other conditions, such as infections, autoimm...
