Safety and First Aid - Basic First Aid for minor cuts and burns

Grade 3ICSE

Review the key concepts, formulae, and examples before starting your quiz.

🔑Concepts

•

First Aid is the immediate medical help given to an injured or sick person before professional medical treatment (a doctor) is available.

•

For minor cuts, the first step is to wash your hands to prevent the spread of germs to the wound.

•

Clean the cut or scratch with clean running H2OH_2O (water) to remove dirt.

•

Apply an antiseptic lotion or cream, which may contain chemicals like H2O2H_2O_2 (Hydrogen Peroxide), to kill any remaining germs.

•

For minor burns, immediately hold the affected area under cool running H2OH_2O for at least 1010 to 1515 minutes.

•

Do not apply ice, butter, or oil to a burn, as these can damage the skin tissue or trap heat.

•

Never prick a blister formed by a burn, as it acts as a natural sterile covering for the wound underneath.

💡Examples

Problem 1:

While playing in the park, Priya scraped her knee and it started bleeding slightly. What are the correct steps to provide first aid?

Solution:

  1. Wash the wound with clean H2OH_2O. 2. Apply pressure with a clean cloth to stop bleeding. 3. Apply antiseptic cream. 4. Cover with a sterile bandage.

Explanation:

Cleaning with H2OH_2O removes pathogens, and the antiseptic prevents infection from bacteria.

Problem 2:

Arjun accidentally touched a hot milk bowl and his finger turned red. Should he put ice on it?

Solution:

No, he should place the finger under cool running H2OH_2O instead of ice.

Explanation:

Extremely cold temperatures from ice can cause further damage to the skin cells. Cool H2OH_2O at approximately 15∘C15^\circ C to 20∘C20^\circ C is ideal to reduce the heat and pain.
