Heine's Law and Landslide Debris Flow Escape Guide

Heine's law. This is the law on industrial safety put forward by Herbert William Heinrich, the security pioneer of the United States industry. Hain rule states: behind every serious accident, there must be 29 minor accidents and 300 threatened and attempted from 1000 onwards accidents.

According to the analysis of the Heine's law, when a major accident occurs, while dealing with the accident itself, we must also promptly investigate the "accident symptoms" and "accidental signs" of similar problems in order to prevent the recurrence of similar problems. To solve the hidden danger of recurrence of major accidents in time and solve the problem in the bud. What is a pity is that whenever disasters occur in China in recent years, there are often hidden man-made disasters. The root cause is that everyone’s safety awareness is not in place, and the security system has not been implemented.

How is the debris flow formed?

As many netizens have said, no one can know which one to come tomorrow or accidentally. If natural disasters such as mudslides suddenly happen to you, do you know how to save yourself?

Stability of solid deposits immersed in water Reduces movement under gravity

Under proper topographic conditions, a large number of water bodies soaked in flowing water, solid deposits on hill slopes or gullies, have reduced their stability, and solidified water-saturated solids have moved under their own gravity to form mudslides.

Sudden outbreak of mudslides is only a matter of minutes

Usually the mud-rock flow bursts suddenly and fiercely, and the area, volume, and flow are all relatively large. The landslide is a small area of ​​the diluted soil mass. Due to the rapid advancement of mudslides, they have a great amount of energy and are therefore highly destructive. The whole process of mudslide flow is generally only a few hours, only a few minutes short.

Multiple human activities will increase the formation of debris flows

There are many factors affecting the strength of debris flow, such as debris flow capacity, flow velocity, and flow rate, among which debris flow has the most significant impact on the degree of debris flow disasters. In addition, a variety of human activities have also exacerbated the role of these factors in many aspects to promote the formation of debris flows.

Where does mudslide occur? What are the hazards?

Occurs frequently in canyons and earthquakes.

Debris flows often occur in canyon areas and in earthquake-prone volcanic areas, and occur during storms. It is a mudslide torrent that erupts instantaneously and is the most serious natural disaster in the mountains.

Hazard: Damage to humans and animals caused by damage to houses and other engineering facilities

The main hazards of mudslides are the destruction of towns, enterprises, factories, mines, and villages, causing human and animal casualties, destruction of houses and other engineering facilities, and destruction of crops, trees, and arable land. In addition, mudslides can sometimes block rivers and not only block shipping but also cause floods.

What should I do if I encounter mudslides?

When you are suffering from mudslides or landslides, first of all be calm and calm. Don't panic. Then take the necessary measures to quickly evacuate to a safe place.

1 run! To go to a safe haven in a vertical direction with mudslides

Refuge sites should be selected on the periphery of the borders on both sides of the landslide. In the event of a landslide, it should be run perpendicular to the direction of the rolling stone. In the case of ensuring safety, the closer to the original residence, the better. The more convenient the traffic, water and electricity, the better.

Do not run in the direction of a landslide when you flee. Not to be overwhelmed, rolling with the landslide. Never choose an evacuation site on an uphill or downhill slope.

2 hide! Can't run out and hide under strong obstacles

When you can't run out, you should hide under a solid obstacle and encounter the collapse of the mountain. When you can't continue to escape, you should quickly hug the surrounding trees and other fixed objects. You can avoid under strong obstacles, or squat in the ditch or in the ditch.

Care should be taken to protect the head and use the clothing around to wrap the head. Immediately report the occurrence of the disaster to the relevant government department or unit. Timely reporting is very important for reducing disaster losses.

3 and so on! Landslides cannot be returned immediately after they stop

Because the landslides will continue to occur, the rash return may be the second landslide. Only when the landslide has passed and the house is away from the landslide, confirm that it is safe before entering.

4 save! Keep in mind three essentials for saving people

Experts pointed out that there are three essential methods to help rescue people and objects buried in landslides: 1 to drain water from the trailing edge of the landslide; 2 to start digging from the side of the landslide body; 3 to save people first and then save things.
