Those distress calls we can’t forget in the wild.

According to their own situation and the surrounding environmental conditions, send out different distress signals.Typically, the three repetitions represent a call for help.

The types of signals are:

Smoke signals

Firelight is very effective as a contact signal.Distress can be based on their own situation: in order to ensure its reliability, during the day on the fire put some moss, green branches, rubber and other smoke;In the evening, you can put some dry wood to make the fire burn and raise the fire.

Setting off three sets of flames is an internationally accepted distress signal, and placing them in a triangle with equal intervals between each pile is ideal, which also facilitates lighting.If fuel is scarce or you are badly wounded, or if you are too hungry or too weak to make three fires, simply light one.

Do not let all signal fires burn all day, but be prepared to keep the fuel dry and light it as soon as any aircraft passes by.The fuel in a fire needs to burn easily and burn quickly when ignited, because some opportunities are fleeting.Birch bark is an ideal fuel.You can use gasoline, but you can’t pour gasoline on a fire.Make a wick with some fabric, soak it in gasoline, put it on a fuel pile, and move the tank to a safe place before lighting it.If the fire burns well after ignition, be sure to add fuel without sparks or embers before adding gasoline.

Smoke is a good signal during the day, so add smoke emitting materials to the fire.The smoke rises into the air in sharp contrast to its surroundings and is easily noticed.

Bright smoke stands out at night or in dark green jungle.Adding grass, leaves, mosses and ferns creates smoke.Actually any damp thing produces smoke, damp straw mat, cushion can fume burn very long time, fly bug also closes hard at the same time hurtful.

Black smoke is most visible in snow or desert. Black smoke is produced by rubber and gasoline.If the smoke is confined to the ground, it can be amplified, so that the heat rises more quickly and carries the smoke to considerable heights.

Ground to air signals

The letters listed below are international distress calls, and “FILL” can help you remember the main ones.A single stick “1” is the most important and easiest to make.The dimensions are 10 meters long, 3 meters wide and 3 meters apart.

Body signal

Body language can be used to express the meaning of the person in danger when the search plane is near.

Semaphore signals

A flag or a piece of brightly colored cloth is tied to the wooden stick. When holding the stick, make a long stroke on the left side and a short stroke on the right side to increase the amplitude of the movement and do the “8” movement.If both sides are close, do not have to do “8” shape movement.A simple stroke will do, one long stroke on the left and one short stroke on the right, the former taking slightly longer than the latter.

Sound signal

If close enough, shout loudly, three short three long, three short;Repeat after 1 minute interval.

Reflective signal

Signal light can be emitted using sunlight and a reflector.Any bright material can be used, such as a tin lid, glass, a piece of metal platinum, a mirror is ideal.Continuous reflection will regularly produce a long line and a dot, a type of Morse code.Even if you don’t understand Morse code, a random reflection can be compelling.At the very least, you should know the SOS code.You can detect a reflected light signal even at a fairly long distance, and you don’t even know where you’re trying to contact the target, so it’s worth exploring, and it’s a no-brainer.Look around the sky and quickly reflect the signal light if an aircraft approaches.This light may be blinding rescuers, so stop reflecting it as soon as you’re sure you’ve been spotted.

Leave a message

When leaving a dangerous place, leave signals for rescue workers to find.Ground signals allow rescuers to know your location or past location, and directional markers help them find your path.Along the way, it is important to leave a marker so that rescuers can not only follow it, but also not get lost when they want to return — it can be a guide if they get lost and find a route they don’t want to take.
