Long Answer Questions
- What should be done in case of gas leakage?
Answer:
• Do not switch on or off any electrical switches or strike matchsticks, as a small spark can cause an explosion.
• Immediately open all doors and windows to let the gas ventilate.
• Switch off the gas regulator knob on the gas cylinder.
• Contact the gas supplier or mechanic immediately to fix the leak.
- What first aid would you provide in following cases?
(a) Chemical burn
(b) Nose bleed
Answer:
(a) Chemical Burn: Wash the affected area with plenty of clean running water immediately to remove/wash off the chemical. After washing, treat it like a minor burn with antiseptic cream and cover with a clean cloth. Seek medical help.
(b) Nose Bleed: Keep the person sitting upright with their head held slightly forward or comfortably back. Pinch the soft part of the nose firmly for 5–10 minutes. Ask them to breathe through their mouth and not blow their nose. Apply a cold compress/ice pack on the nose bridge.
- How will you give first aid in case of a snake bite?
Answer:
• Do not allow the patient to move, as movement increases blood circulation and spreads poison faster.
• Tie a tight bandage (tourniquet) just above the bite area to slow down the flow of venomous blood to the heart.
• Rush the patient immediately to the nearest hospital for anti-venom treatment.
- Describe safety rules to be followed in case of fire.
Answer:
• Do not panic and call the fire emergency service (101).
• Use appropriate firefighting tools: water for paper/wood fire, sand/fire extinguisher for petrol or electrical fire.
• If clothes catch fire, do not run; roll on the ground and cover with a thick blanket or coat to cut off oxygen supply.
• Do not wear synthetic clothes like nylon in the kitchen or near fire.
- How will you follow safety rules on road?
Answer:
• Always walk on the footpath and cross the road only at zebra crossings.
• Obey traffic light signals and road traffic signs.
• Wear helmets while riding two-wheelers and seatbelts in cars.

- How will you make a tourniquet?
Answer:
• Wrap a piece of strong cloth or bandage tightly above the wound.
• Insert a stick into the loop of the cloth.
• Twist the stick to tighten the bandage until the heavy bleeding stops, then tie the free end of the stick to hold it in place.
- HOTS (Higher Order Thinking Skills) Questions

- Why do ambulances and firebrigades have sirens?
Answer:
Sirens act as loud audio warnings to alert other commuters on the road, allowing emergency vehicles to get priority right-of-way through traffic.

Answer:
Fire requires oxygen to burn. Covering a person with a thick blanket cuts off the atmospheric oxygen supply (smothering the fire), extinguishing it quickly.
