Question 4: What do you mean by three defenses of ancient buildings? Fireproof, burglarproof and waterproof.

Question 5: Understand the role of safety technology in public security work. The rapid development of security technology in China has attracted close attention from all walks of life. Due to the limitation of many historical and practical conditions, many theoretical and practical problems in China's security technology prevention work have not been seriously studied and defined. In view of some problems encountered in practical work, this paper puts forward some thoughts and suggestions of the author, hoping to play a role in attracting jade. If there is anything wrong, colleagues in the industry are welcome to criticize and correct me.

First, the concept of security.

Security is a historical concept. It is first and foremost a natural choice for human survival. With the continuous development of productive forces and social and economic progress, its content and form are constantly changing, gradually forming specialized technologies and corresponding industries, which have become an important part of social and economic life.

1. General concept of security (security &; Protection)

According to the Modern Chinese Dictionary, the so-called safety means that there is no danger, no infringement and no accident. The so-called prevention means preparedness, vigilance, preparedness means preparing for an attack or avoiding victimization, and vigilance means preparedness and protection.

Based on the above explanation, can we define security as: preparing and protecting against attacks or avoiding victims, so that the protected object is in a safe state without danger, infringement and accident?

Obviously, here, safety is the purpose and prevention is the means. It is the basic connotation of safety prevention to achieve or realize the purpose of safety through preventive measures.

2. Two safety interpretations (safety and security)

Security in Chinese has two interpretations in English: security and security.

The Modern Advanced English-Chinese Dictionary published by Oxford University mainly explains the word "security" as follows: safety and security; Insurance (lock), insurance (box), etc. The main explanation of the word safety is: safety, no danger, no trouble; Provide something safe to avoid danger or worry; Collateral, collateral; Security (police), security (troops), etc.

In fact, the security mentioned in Chinese is a kind of generalized security, which contains two meanings: first, it refers to the security of natural or quasi-natural attributes, which corresponds to security; In English; Secondly, it refers to social and humanistic security, that is, security with obvious humanistic attributes, which corresponds to security. The safety damage of natural or quasi-natural attributes is mainly not caused by people's purposeful participation, such as the safety damage caused by natural disasters (floods, droughts, earthquakes, etc.). ) and quasi-natural disasters (product design defects, deterioration of environmental sanitation conditions, etc. The destruction of social and humanistic security is mainly caused by people's purposeful participation, such as invasion, theft, robbery, destruction, explosion and other illegal and criminal activities. Therefore, security in a broad sense should include two meanings: security and security, and the security precautions we often say are mainly security in a narrow sense: security, which is commonly called "security" abroad.

3. Loss prevention and crime prevention are the essential connotations of safety prevention.

In the west, the word "safety" is not used, but loss prevention &; The concept of crime prevention. Just as Chinese safety and prevention are used together to form a new compound word, in the west, loss prevention and crime prevention are also used together. Loss prevention and crime prevention are two aspects of security. In foreign countries, loss prevention usually refers to the focus of social security industry, while crime prevention is the focus of police law enforcement departments. The organic combination of the two can ensure social stability and security. In this sense, loss prevention and crime prevention are the essential connotations of security.

To sum up, security is not only a public security business (police executive department), but also a social public utility and socio-economic industry. Their development and progress not only depend on the development and progress of science and technology, but also provide a superior social environment for the progress and development of science and technology.

4. Social security technology with China characteristics.

It should be pointed out that loss prevention is still a relatively broad concept. Broadly speaking, it includes disaster prevention and mitigation ... >; & gt

Question 6: How to protect the three defenses of safety control panel, safety circuit board and pcb board? If the security control panel, security circuit board and pcb are used as the three-proof protection technology, we have been using the moistureproof protective paint products for circuit boards produced by Yongan Electronic Chemical Industry. After the instrument circuit board is assembled, we can brush or spray a layer of Yong' Anya -630 waterproof paint on the surface of the circuit board, which has good hydrophobicity and high and low temperature resistance after being completely dried. After curing, it becomes a transparent protective film with excellent insulation, moisture-proof, leak-proof, shock-proof, dust-proof, anti-corrosion, mildew-proof, anti-loosening of parts and anti-corona insulation functions, which is worth recommending.

Question 7: For several kinds of security supplies that special operators need to equip, please ask professionals to give specific names, materials and other information of the supplies. It is difficult for anyone to answer all the questions with a score of 20.

I have done aerial work and need a set of safety belts, safety buckles, emergency lanyards, safety helmets and three-proof shoes. The workplace should also prepare high-altitude fast descending rope and slow descending device. That should be enough.

I don't know the rest.

Question 8: Three-proof paint is sprayed on the tested board, and the adhesion can not meet the requirements. What is the reason? The blackboard was wiped clean. 10 points mainly do the following checks:

1, paint condition. For example, whether the quality is qualified, whether it is evenly mixed, whether it has good fluidity and so on.

2. Air pressure. For example, whether the air pressure fluctuates, whether there is too much water, etc.

3. Nozzle. Whether there is local blockage, deformation and other phenomena.

4. Environmental conditions. Whether there is the influence of the wind and so on.

5. Operation. Have you followed the procedure strictly, and so on.

Analysis of product quality is nothing more than five aspects: people, machines, materials, law and environment.

I hope it helps you.

Question 9: What measures should be taken for warehouse security during the Spring Festival holiday, such as fire prevention, theft prevention, leakage prevention and three defenses?

See if there is a fire hazard.

It depends on whether the doors and windows are in good condition and damaged.

It depends on whether the goods are leaking or not, and whether the pipeline is leaking.

Then there are some overall class inspections and measures.

For example, whether the fire-fighting facilities are in good condition, smoke alarms and fire hydrants; Whether the company has a unified power outage; Whether the emergency contact letter is complete; All that's left is a seal.
