I will share knowledge that is related to our daily life.
When you use elevator , let that elevator come and rest upon the floor. Don't go inside an elevator in hurry. Always see the floor of elevator because some time elevator malfunction and people have fallen directly to the ground floor due to their negligence.
If a person catches fire. Tell him to roll down on floor and put blanket or any large piece of cloth so that supply of oxygen can be stopped from the fire. Use fir extinguisher if possible.
Gas Stove Knob.
Always check the knob of gas stove before you sleep because sometimes it causes fire in many homes. Stay alert when you use “LPG gas cylinder" for cooking , specially in India because many people have died due to explosion from LPG gas cylinder.
Run when you see pack of stray dogs 🐕.
If you are alone and you pass from road that has pack of stray dogs , then run and never look back because in group , stray dogs become stronger and their natural instinct of hunting increases. They will attack you and you can't save yourself from 6–8 stray dogs.
Always sleep in proper ventilated room.
We know that we take oxygen (O2) and release carbon dioxide (CO2). In room that has no proper ventilation , stop the flow of fresh air that contain oxygen and if you sleep in that room you will suffer from carbon dioxide poisoning that will cause head ache and other health issues , people also die due to suffocation in such places.
Don't cover yourself with blanket when you sleep , it will stop fresh air and you will feel headache.
