Using First Aid Kit to Render First Aid
Use the First Aid Kit to render first aid
First aid
is the immediate care given to accident victims or an injured person
before he/she is taken to the hospital for further medical treatment. It
reduces pain and it helps to bring hope and encouragement to accident
A First Aid Kit is
a small box which is placed in a safe and accessible place in the lab
and is used for the storage of instruments and chemicals for first aid.
Contents of a first aid kit and their uses
Contents Uses
1. Pair of scissors To cut adhesive tapes, bandages and gauze
2. Rolls of adhesive tape To hold firmly into wounds bandages, gauze and cotton wool
3. Bandages and cotton wool To clean and cover wounds
4. Sterilised new razor blades Used when treating new or old wound
5. Sterilised wound To clean and cover wounds

8. Iodine tincture To clean fresh cuts and bruises
9. Soap To wash hands and wounds
10. Antibiotic solution. To clean wounds
Warning Signs
Identify warning signs
signs are signs on the containers of chemicals as warnings about the
danger of the contained chemical. There are six warning signs.
are substances can explode. An explosion is a forceful rapid reaction
which involves the throwing off particles at high speeds.
The sign means that it is dangerous to keep explosives in glass containers.
This is a chemical/substance that helps a burning substance to burn faster.
agent makes a small fire to become bigger. Heating a mixture of an
organic material with an oxidising agent may cause explosion. Eg;
heating potassium permanganate with saw dust.
These substances catch fire easily. They should not be kept near open flames. If heated,anelectric heater should be used.
These substances burn skin as well can corrode floors and desktops.
by accident, a corrosive substance comes into contact with your skin,
go to the sink and wash your skin with a lot of water. Examples;
Concentrated mineral acids like HCl and HNO3 II. Concentrated alkalis
like NaOH and KOH
are very poisonous and can cause death immediately after use or after a
few days. They should not be allowed to come into contact with you.
-If you come into contact with such a chemical accidentally, wash it away with a lot of water.
– these substances may cause illness or endanger your health. They
won’t kill instantly but they are lethal. Irritating substances- cause
pain in eyes or on your skin and can endanger your health if you are in
contact with them doe too long.
They should be handled according to the stipulated instructions.
