1. Avoid using mobile phones while participating in traffic
Safety and health experts advise that you avoid using mobile phones while participating in traffic. The phone will divert your brain's attention to it, ignoring the situations around you, and your brain will not perceive potential dangers and risks that may occur to you. For example, if a car is losing control and heading towards you, you will not be aware of what is happening.
For motorcycles, riding with one hand is not as secure and safe as using both hands. Moreover, holding the phone with the left hand will prevent the rider from using the combined braking system on scooters. In unexpected situations, this is also a reason why riders use the front brake abruptly, leading to accidents.
For cars, using a phone with one hand will make you lose focus while driving, and you cannot react promptly to unexpected situations. Many accidents have occurred because people were busy using mobile phones and crossed the road without proper observation, changed lanes without signaling, or ignored red lights... affecting other vehicles in traffic and causing accidents.


2. Ensure you are wearing appropriate clothing in cold weather
Remember that wet skin loses heat much faster, so try to keep your skin dry in winter. Ensure that your body temperature doesn't warm up too quickly by wearing clothes made of wool - such materials absorb moisture. Cotton and other low-moisture-absorbing fabrics will make you feel cold all day if you wear clothes made from them.
If you know you might get wet, you should wear a waterproof layer outside to stay warm. If water seeps in, the clothing layer will only make you colder. You can get wet from rain, snow, and splashes (like when boating or encountering puddles on the road). Besides keeping dry, you also need to look for clothing with good insulation material. You might have heard of sheep's wool, but this material is not for everyone. Explore other options with more readily available materials and hit the shopping spree!


3. Eliminate blind spots when driving by adjusting your car mirrors before moving
During driving lessons, you were probably instructed on adjusting rearview mirrors. You've also been warned about blind spots on both sides of the car, so you should check blind spots before changing lanes or turning. However, you can adjust your car mirrors to eliminate these blind spots, meaning you only need to glance quickly at the mirrors before changing lanes, and that's crucial. You need to start by adjusting the side and center rearview mirrors. To ensure the view covers as accurately as possible.
Adjusting your mirrors is a way to help you see positions that are not visible around the edges of your car. This adjustment will help you eliminate any blind spots on both sides of the car. Properly adjusting the position of the mirrors ensures you can always see a car behind preparing to move up in front of your car. To ensure accuracy when adjusting the rearview mirror, do it directly from the driver's seat.


4. Prevent the risk of choking by using the Heimlich maneuver
Choking often occurs when you have something stuck in your throat. In this case, you should perform the abdominal thrust method. To perform abdominal thrusts on others, you need to stand behind the person, place your hands on their abdomen.
Your hands should be held tightly, jerk upwards as if lifting the person. Repeat until the object in the person's throat is expelled, usually no more than 5 times. If the above action is not effective, place the person on a flat horizontal surface such as a table, chair, or railing and place your hand on the abdomen, jerking forcefully into their stomach. Repeat until the obstructing object is dislodged.


5. Avoid inflating life jackets while the plane is taking off
During the safety briefing, the flight attendant will show you the location of the life jacket, typically stored under your seat. In the event of a water landing, when the flight attendant instructs you to put on the life jacket, put it on but don't inflate it hastily. Wait until you reach the aircraft door and receive the signal from the flight attendant, as that's when you can exit the aircraft. When exiting the aircraft, pull the life jacket inflation cord.
If you intentionally inflate the life jacket while still inside the aircraft, it not only fails to aid in a safe escape but, on the contrary, significantly increases the risk of drowning. When the plane sinks into the sea and water floods the cabin, a person wearing an inflated life jacket will float to the water surface and be wedged against the aircraft ceiling. It becomes challenging for them to escape. Subsequently, water gradually rises to the cabin ceiling, leading to the victim's demise. Incorrectly wearing the life jacket can contribute to a tragic outcome.


6. Avoid pouring water into a boiling oil pan
Avoid pouring water into a boiling oil pan because oil is lighter than water. When they come into contact, oil molecules will float to the surface and spread wherever the water reaches. When a significant amount of water contacts boiling oil, it ignites, but since water is heavier, it sinks below the oil, immediately vaporizing due to its boiling point of 100 degrees Celsius. Water vapor carries oil particles and rises into the air, resulting in a large and easily ignitable fire, posing a high risk of a blaze.
Firefighters have warned everyone not to use water to attempt to extinguish a blazing fire above a boiling oil pan containing fats or oil. As water is denser than oil, it immediately sinks to the bottom of the pan and begins to vaporize, intensifying the flames. In this situation, you should quickly cover the oil pan with a thick cloth, turn off the gas stove, or disconnect the power. Additionally, you can use a fire extinguisher in this case.


7. Remember that your body's tolerance is limited
As numerous studies have pointed out, each person's body has its limits; no one can stay healthy without eating or breathing. Always remember the following principles: A normal person cannot survive more than 3 minutes without air; Humans cannot endure more than 3 hours in harsh weather conditions; People cannot live more than 3 days without water; Humans cannot survive more than 3 weeks without food.
Our bodies maintain a stable temperature at 37 degrees Celsius. However, if the environmental temperature reduces body heat, significant effects will occur. If the body temperature drops to 35 degrees Celsius, your limbs will become shaky and challenging to move. At 32 degrees Celsius, most people will faint, and the body will give up trying to maintain heat. Breathing decreases, and heart rhythm disorders occur at 28 degrees Celsius. When the body temperature reaches 20 degrees Celsius, the heart stops beating. Nevertheless, there was a case of a girl walking in -20 degrees Celsius weather with a body temperature of only 16 degrees Celsius but was still rescued.
It seems we tolerate cold better than heat. The highest temperature the body can endure and maintain life is 42 degrees Celsius because at this temperature, essential proteins in the body begin to break down. Even with full gear, firefighters can only withstand environmental temperatures up to 93 degrees Celsius.


8. When in a fire
When discovering a fire, stay calm and composed, the first thing is to stabilize your breathing and figure out how to handle it. Observe where the fire and smoke are. If the fire is small, try to extinguish it using a fire extinguisher, CO2 canister, sand, a wet blanket, or other items you can find nearby that can help put out the fire.
If you're unfortunate enough to be trapped in a fire, try to stay as close to the ground as possible. Toxic gases like CO2, CO, ammonia, organic acids, or smoke often linger higher up. So, don't hesitate to use a wet cloth to cover your nose and crawl on the ground to escape the fire.


9. Important Considerations During Takeoff and Landing
Researchers indicate that 80% of airplane accidents occur during specific time frames. Be cautious in the first 3 minutes after takeoff and the 8 minutes after landing. The best way to cope with this is to stay vigilant and alert during these critical moments.
Pay attention to small actions like folding tray tables during takeoff/landing: Tray tables take up a significant area at the seat. Similar to the upright seat regulations, folding the tray table will help passengers in the same row move quickly and minimize collisions in case of an unfortunate event. Avoid using the restroom during takeoff/landing: The restroom lacks safety equipment, and when the plane experiences turbulence, passengers cannot be securely fixed in one place, making them prone to collisions or even getting stuck here. Close window shades during takeoff/landing: If evacuation is necessary due to an emergency, open window shades will help passengers quickly identify the safest exit route and avoid reduced visibility when leaving the aircraft. This action also aids the cabin crew in easily observing any abnormalities on the fuselage, wings, or aircraft engines or foreign objects outside the aircraft. They can then promptly report to the control station for assistance.


10. Always Carry Personal Identification Documents
Ensure you always carry your national ID card, a business card, and documents containing medical information such as blood type, allergies, etc., on your person. This way, if something unexpected happens, even a complete stranger can assist you quickly and effectively. Don't forget to carry a list of personal contact addresses, including phone numbers of those who need to be notified in case of an emergency.
Cultivate this beneficial habit for yourself. Not only in the event of an accident but also in many other situations, there is a sudden need for personal identification documents. To ensure you don't have to waste time returning home to fetch documents, always carrying them with you is a significant advantage.
