Let Us Begin!

Accidents can happen anywhere -- at home, on the road, or at school. But many accidents can be prevented if we follow simple safety rules. And when a small accident does happen, knowing first aid can help us take care of ourselves and others before a doctor arrives.

First aid means the first help given to an injured or sick person right away, using simple things available nearby. It is not a replacement for a doctor, but it can reduce pain and prevent the injury from getting worse. Let us learn how to stay safe and help others.

Safety at Home

Our home should be the safest place, but many accidents happen at home when we are careless. Here are important safety rules:

Never play with matchsticks, candles, or the gas stove. Fire can spread very quickly.
Do not touch electrical switches or plugs with wet hands. Water conducts electricity and you can get a shock.
Keep medicines and cleaning liquids away from young children. Never taste unknown liquids.
Do not run on wet or slippery floors. You can slip and hurt yourself.
Never lean out of windows or balconies, especially in tall buildings.
Always use the handrail when climbing stairs.
Keep sharp objects like knives and scissors in a safe place after use.

Think about it: What would you do if you smell gas leaking from the kitchen cylinder at home?

Safety on the Road

Roads in India can be very busy. Following traffic rules keeps us safe:

Always walk on the footpath (pavement). If there is no footpath, walk on the left side of the road, facing the traffic.
Cross the road only at a zebra crossing or traffic signal. Look right, then left, then right again before crossing.
Understand traffic lights: Red means stop, Yellow means get ready, Green means go.
Never play on or near the road.
Always wear a seatbelt in a car. Children should sit in the back seat.
When riding a bicycle, always wear a helmet and ride on the left side of the road.
Never put your hands or head out of a moving bus or auto-rickshaw.

Safety at School

School is a place for learning and fun, but we must be careful here too:

Do not push or run on the stairs or in the corridors.
Do not climb on desks, chairs, or walls.
During games, follow the rules and play fairly. Do not fight or push others.
Use scissors and compasses carefully. Do not point them at anyone.
During a fire drill, walk in a line calmly to the assembly point. Do not panic.
Drink water from the school water filter, not from unknown taps.

Think about it: Why is it important to walk in a line during a fire drill instead of running?

Basic First Aid

Here is what you can do for common small injuries:

Injury	What to Do
Small Cut or Wound	Wash the cut gently with clean water. Apply an antiseptic cream if available. Cover it with a clean bandage or adhesive strip (band-aid).
Minor Burn	Hold the burnt area under cool running water for at least 10 minutes. Do not apply ice, butter, or toothpaste. Cover loosely with a clean cloth.
Nosebleed	Sit up straight and lean slightly forward. Pinch the soft part of the nose firmly for 10 minutes. Breathe through the mouth. Do not tilt the head back.
Insect Bite or Sting	Wash the area with soap and clean water. Apply a cold, wet cloth to reduce swelling and pain. If there is a lot of swelling or difficulty breathing, call for help immediately.

Emergency Numbers in India

In an emergency, you must know whom to call. Memorise these important numbers:

Number	Service	When to Call
100	Police	Theft, crime, or any danger from people
101	Fire Brigade	Fire at home, school, or any building
108	Ambulance	Serious injury or medical emergency
112	All Emergencies (Single Number)	Any emergency -- police, fire, or ambulance

Remember: The number 112 works for all emergencies. If you are confused about which number to call, just dial 112. It works even without a SIM card in the phone.

Think about it: If you see a fire in your neighbour's house, which number would you call first?
