Class 3 Science Question Answers - Safety and First Aid

Q1: What are some common causes of accidents at home, and how can we prevent them?
Ans: Common causes of accidents at home include fire, electricity, and sharp objects. To prevent them, always switch off the gas regulator when not in use, check for gas leaks, inspect wiring and electrical appliances regularly, and be cautious when handling fire-related items. Avoid wearing synthetic clothes near fire, and if someone's clothes catch fire, roll them on the floor or cover them with a blanket.


Q2: How can we extinguish a small fire, and why should we not use water for all types of fires?
Ans: Small fires can be extinguished by throwing mud or sand, pouring water, or using a fire extinguisher. Water should not be used on electrical fires or fires caused by petrol or kerosene because it can lead to electric shock or spread the fire.


Q3: What safety measures should we follow on the road to ensure our safety and the safety of others?
Ans: On the road, we should use zebra crossings or subways to cross, wear helmets while riding two-wheelers, avoid walking through stopped vehicles at crossings, not run on the road, walk on the footpath, and use safety belts in cars while following traffic signals.


Q4: What is first aid, and why is it important?
Ans: First aid is the care given to an injured person before a doctor or nurse can see them. It is important because it can prevent injuries from worsening and provide immediate relief.


Q5: How should we treat minor burns, and what should be done for severe burns?
Ans: For minor burns, cool the burnt area with cold water and apply antiseptic cream or a baking soda paste. For severe burns with blisters, do not break them, wash with soap and water, and cover with a clean cloth. Seek medical help for very serious burns.


Q6: What should be done for chemical burns, and why is it important to wash them immediately?
Ans: For chemical burns, wash the burnt area immediately with plenty of water to remove the chemical and prevent further damage.


Q7: How should we care for wounds, and why is it important even for small wounds?
Ans: Care for wounds involves washing with soap and water, applying tincture of iodine, and covering with a plaster or bandage. Even small wounds should be cared for because germs can enter through cuts and wounds.


Q8: What should we do in case of animal bites, and why is it crucial to seek medical attention?
Ans: In case of animal bites, wash the wound with soap and water, apply antiseptic, and cover with a bandage. Seeking medical attention is crucial because some animal bites, like those from dogs and monkeys, can lead to serious diseases like rabies.


Q9: How should we handle fractures, and why should we avoid moving the fractured part?
Ans: Handle fractures by not moving the injured part, providing support using a sling or splint, and seeking medical help immediately. Moving a fractured part can worsen the injury.


Q10: What should be done in case of a nosebleed, and why is it essential to follow specific steps?
Ans: To stop a nosebleed, loosen clothing, sit upright with the head back, apply pressure to the bleeding side, use an icepack, and breathe through the mouth. Following these steps helps control the bleeding and prevent further discomfort.
