Safety precautions during earthquake
For a person present inside of a building:
1. Take shelter under a table and stay there till the shaking stops.
2. Stay away from tall and heavy objects that may fall on you.
3. Do not get up, if you are in bed. Protect your head with pillows.
4. Stay indoor until shaking stops and it is safe to move outside. Most of injuries occur when people, inside the building, attempts to move to a different location within the building or try to leave it.
For a person caught outside in the open:
1. Find a clear spot, away from buildings, trees, bridges and overhead power lines. Drop to the ground.
2. Do not come out, if in a moving vehicle. Drive slowly to a clear spot and stay inside. Come out only when the tremors stop.
Safety precautions after the earthquake
1. Stay calm for a while. Expect after shocks. These shocks can cause additional damage.
2. Beware of possible tsunami, if you live in coastal area.
3. Carefully inspect utilities/supplies.
4. Use telephones only in emergency.
5. Stay away from damaged areas.
6. Help the injured ones.
