When you are traveling or under certain circumstances, you might be caught in a danger. Therefore, it is necessary for you to know something about asking for help, besides shouting “Help! Help!” Under normal circumstances, you can use signals, by repeating three times a symbolic action to seek assistance.
Make sound or noises for help
When you encounter a danger, in addition to shouting for help, you can also sound a whistle, beat basins, and beat wooden items. Break containers or glass to send out SOS signal.
Use of reflectors
Case of crisis, to use optical reflectance signals is the most effective approach.
Common tools: a flashlight, mirrors, canned Paper, glass, spectacles, back spectrometer. Flash per minute, six times, pause a minute, then repeat.
Throwing things
When you encounter a danger in a tall building in case of crisis, you can toss soft objects, such as pillows, books, empty plastic PET bottles, to attract the attention from the others.
Use fire or smoke
Light three consecutive fires, equal distance between them.
Heavy smoke during the day (use combustible fresh twigs, grass and other plants to produce smoke), at night, you can make a fire - dazzling blazes- for help.
Make ground signs for help
On a broader ground, such as grasslands, beaches, snow ground, you can make ground signs, by using twigs, stones, tents, clothing and all other available materials. For example, the grassland can be made into certain signs by cutting the grass, and walk in the snow to some signs.
Please remember the following words: SOS, SEND, DOCTOR, HELP, INJURY, TRAPPED, LOST, WATER.
Leave signs
When you leave the place to escape from the danger, leave some signs, in order to allow rescue personnel to find and understand your position or your trace.
Tips for your leaving signs to make good records of your location, and trace of direction.
- Rock or gravel should be placed in the shape of an arrow.
- Put a stick between tree branches, pointing your way with the top end.
- Tie among grasses a direction sign to show your way.
- Place on the ground a forked branch, with bifurcation point to the action.
- Made up a heap with small stones, then put a small stone on the edge of it to show the direction.
- With a branch, cut a deep arrow on it to show direction.
- Make a cross by two sticks or with stones to mean that the approach is wrong.
- Use three rocks, sticks to show hazard or emergency.
Use SOS codes
SOS codes are the codes of international generic emergency.
Among the codes, S will be expressed as "..." that is the three shot signals; and O means "- - -" that is, three long signals.
Thus, SOS can be expressed by using a "three short, three long and three short".
Use light, such as switchgear, flashlights, lamp, emergency lights, auto headlamps, or use voice, as sirens, horn of a car to send out an SOS.
Send out a group of short-long-short signals as SOS, then pause, then the next group.
Attention:
- Under normal circumstances, repeated three times as a symbolic action to seek assistance
- Make the signal six times a minute, or wave flags, also, six times a minute
- Choose a high place to send signals to make it easier to attract attention from the others
- Light a fire with the materials that can be ignited quickly
- Bark is an ideal choice
- Use gasoline if available, but you should not dump the gasoline on the fires
- Use some fabrics, and soak them in gasoline, then move the gasoline to a safe place before ignition. If you want to add some fuel when the fire is going to burn out, the fire should be extinguished before adding petrol, to ensure that the adding of fuel is in the absence of any spark or ember.
- During the day, smoke is a good locator, so add some materials that can easily make smoke. The heavy smoke can easily attract the others' attention.
- At night or in deep green jungle, light-color heavy smoke is necessary
- Add green grass, leaves, mosses and ferns, it will have a heavy smoke
- In fact, any moist ignitable material can produce smoke. Wet mats or cushion can be smoked burning for a long time.
- Make black smoke in snow or the desert, for it is the most eye-catching. Rubber and gasoline can produce black smoke.
- If under a weather conditions that smoke can only waft near the surface of the ground, you can increase fire. Heating will give more flow- upward momentum which can carry smoke to a considerable height.
