Let me say a few words, the principle of energy release: energy is the ability of objects to do work, and human society is the process of constantly developing and utilizing energy. Energy is also the source of harm to human body. Without energy, there will be no accidents, and without energy, there will be no injuries. The basic idea is that accidental or abnormal energy transfer is the cause of casualties. That is, the cause of personal injury can only be that part of energy is transferred to the human body, and the accident is the abnormal or unexpected release of energy.

According to different uses and production methods, energy can be converted into various forms. According to the form of energy, it can be divided into potential energy, kinetic energy, thermal energy, chemical energy, electrical energy, radiant energy, acoustic energy, biological energy and so on.

In the theory of energy transfer, the damage caused by energy can be divided into two categories. The first type of injury is caused by the application of energy that exceeds the threshold of local or systemic injury. Every part of the human body has a damage threshold for every kind of energy. When the energy applied to the human body exceeds the threshold, it will cause harm to the human body. Most injuries fall into this category. For example, a person's safe voltage is 36 volts.

The second kind of injury is caused by affecting local or systemic energy exchange. Such as suffocation caused by mechanical or chemical factors (such as drowning, carbon monoxide poisoning, etc.). ).

Another important concept of energy release theory is that under certain conditions, whether a certain form of energy can cause injuries and accidents mainly depends on the size of energy, the length and frequency of contact, the concentration of force, the injured part and the time of setting up barriers.

Method library: 1. Energy limiting system.

2. Replace dangerous energy with safer energy. For example, replacing electricity with hydraulic coal mining.

3. Apply a system to prevent energy accumulation. For example, the area is increased and the setting space is reasonable.

4. Control energy release. For example, building safety doors and isolation windows can reduce energy release.

5. Delay energy release. For example, safety valves and relief valves are used to control high-pressure gas;

6. Open the channel to release energy. Take the safe passage, for example.

7. Set up energy barriers. For example, setting low thermal conductivity ground ~ building materials and earthquake-proof protective walls.

8. Set up barriers between people, things and energy. For example, set fire doors and fire seals; Set a safety net for high-rise buildings to prevent potential energy from flowing back to the human body.

9. Set up shielding between people and things. For example, wear safety helmet, dust mask and electric safety shoes.

10, improve the safeguard standard. For example, the use of high-quality building materials and mechanized management systems.

1 1, change the process. Turn an unsafe process into a safe process.

12, repair or first aid. Treatment and correction to reduce the degree of injury or restore the original function; Do a good job in emergency rescue and carry out self-help education.
