Common sense of safe use of electricity in banks

Compared with cash, bank card is a safe and fast means of payment.

At present, various commercial banks and UnionPay have taken various technical measures and safety measures to ensure the security of cardholders' funds to the maximum extent. However, it is very important for cardholders to have some necessary safety awareness, understand some common bank card crimes and master basic prevention skills when using bank cards.

The following are ten security problems that cardholders may encounter in the process of using bank cards: Question 1: How should cardholders protect their bank card information security? Some criminals will steal the cardholder's bank card account information, steal the cardholder's account funds after forging a fake card, steal the identity information of others, and impersonate others to handle credit cards for malicious overdraft consumption. Therefore, cardholders need to protect their bank card account information (card number, password, etc. ) and personal information.

Precautionary tip: 1, it is very important to set the password skillfully. After getting a new bank card, the cardholder should immediately change the password regularly.

Set some relatively complicated passwords instead of simple passwords such as 123456 and 888888, and modify them regularly; Don't use your birthday, home phone number, etc. As a password, and under any circumstances, don't easily disclose account information such as bank card password to others. Remember, no one (including bank staff) has the right to ask for your personal password.

2. Cover up your personal information. Cardholders should pay attention to protecting personal information to prevent personal information from being abused by criminals.

If you don't leave your personal data to unfamiliar companies or individuals, don't leave real personally identifiable information (including family and work information) online. If you need to leave a copy of your ID card for a certain business, it is best to indicate the purpose on the copy, such as "recruitment only". Question 2: I often see advertisements on the Internet or in newspapers, claiming that I have been authorized by the bank to help me handle gold cards or provide credit card financing. Is it credible? What if an individual wants to apply for a credit card? Generally speaking, most of the so-called intermediaries who claim to be able to help with gold cards or provide credit card financial services are not credible. People should pay attention to the following knowledge when handling credit cards: 1. Applicants should apply for credit cards through formal channels. If they want to apply for a credit card, they should go directly to the bank counter or a formal marketing agency authorized by the bank. Such marketing agencies do not need to pay any card handling fees, and will not provide you with credit card financing or cash withdrawal services.

2. Credit card is a revolving credit line given by the bank based on the applicant's personal good credit status, and the issuing bank will adjust the corresponding credit line according to the cardholder's credit card usage and credit status. Therefore, you can't go through some illegal intermediaries for convenience or to obtain a higher credit limit, and you can't actively participate in credit card cashing. Once discovered by the bank, it will do great harm to your personal credit status.

3. If cardholders find illegal intermediaries or cashing merchants, they are welcome to actively call the issuing bank or UnionPay customer service hotline 955 16 to report, so as to maintain a healthy and sound development environment for bank cards. Question 3: What should cardholders pay attention to when using ATM and other bank card self-service terminals? Some criminals will set up some "organs" in self-service banks and ATM machines, and at the same time peek at the passwords behind them. When the cardholder can't trade normally or creates the illusion that the card has been swallowed, pretend to be a good-hearted person to help swipe the card, and take the opportunity to change the card or take it out after the cardholder leaves.

Therefore, cardholders should pay more attention when using ATM and other bank card self-service terminals. Precautions: 1. Be careful when using the self-service banking terminal, pay attention to whether there are suspicious people around, avoid interference from others when operating, and prevent others from peeping at the password, and avoid spitting money when swallowing cards. You should call the issuing bank's national unified customer service hotline and get in touch with the issuing bank in time.

2. Don't trust "good people". Don't dial the phone number attached to the machine, don't throw away the printed documents at will, and you don't need to enter a password to swipe your card for access control.

When you use a credit card, the card won't leave your eyes. In public places (such as supermarkets, restaurants, etc. ), you can block the password keyboard with one hand to prevent others from peeping at the password.

Question 4: How to identify false short messages or phone calls? SMS and telephone fraud are a kind of fraud means that criminals fabricate some seemingly reasonable reasons through telephone, mobile phone and other communication tools, and take advantage of the cardholder's greed or nervousness to defraud the cardholder's account funds or account information such as card number and password, or to trick the cardholder into transferring money to ATM machines. Common examples are: the current popular short message fraud pretending to be a bank notice or a prize-winning notice, such as "winning the prize", "bank card consumption", "returning the car purchase tax", pretending to be a mobile employee "returning the phone bill", or calling to falsely claim that the cardholder's relatives and friends need funds in an emergency, etc.

Precautions: 1. When you receive suspicious letters, emails, text messages, phone calls, etc. You should be careful to confirm, don't be greedy for petty advantages and don't be nervous. 2. If you have any questions, go directly to the counter of the issuing bank to ask, or call the unified customer service hotline of the issuing bank (generally starting with "95") or the UnionPay service hotline 955 16.

Question 5: What should I do if I encounter suspicious text messages or phone calls? First of all, it is to identify the style of false short messages. The institutions such as "Bank Card Management Office", "Joint Management Bureau" and "National Financial Center" in fraudulent short messages simply do not exist. Please be careful when you receive such a message.

2. What are the precautions for electricity safety?

There are two main safety problems in electricity consumption, one is personal safety and the other is property safety.

In order to prevent accidents, pay attention when using electricity: (1) Don't stand on the ground and touch the fire line; Stand on the insulator and wear insulated shoes. Don't let your body touch the live wire and the zero wire at the same time. (2) Protect wires, plugs, sockets, lamp holders and electrical insulation.

To keep the insulation dry, do not pull the switch, plug in or pull out the plug with wet hands. (3) Don't touch the wire with metal objects, and don't hang the wire on the nail to avoid short circuit.

(4) It is forbidden to use copper wire instead of fuse and rubber instead of electrical insulation tape. (5) Install an electric shock protector in the circuit and regularly check the sensitivity of the protector.

3. What is the common sense of safe electricity use?

The peak of electricity consumption in summer is coming. With the improvement of living standards and the increase of household appliances, faults caused by overload electricity use frequently occur. In order to ensure the safety of electricity consumption in summer, users should calculate their total electricity consumption before the summer comes and compare it with the maximum rated current of electric meters and power lines. If it is not enough, they should report to the power supply department in time to increase the capacity of the meter. It is best not to start high-power appliances such as air conditioners and microwave ovens at the same time, otherwise the instantaneous surge current will be too large, which will burn out the electric meter.

In areas with complex lines, the power supply should be installed by professionals, otherwise it will cause serious consequences. Copper wire and aluminum wire are prohibited. Replace the fuse; Signal transmission lines cannot be used instead of power lines; Medical leucorrhea and transparent belt cannot be used instead of insulating black belt.

Residents should actively guard against human invasion of lightning in thunderstorm season. There are four ways for induction lightning to invade: power lines, telephone lines, cable TV lines, external walls of houses or pillars. Therefore, it is very important to check the grounding wire regularly. Because if lightning strikes, the current generated by lightning will be led to the ground along the grounding lead to avoid electrical damage.

Many families keep the TV on standby or off after watching it. In fact, from the perspective of electricity safety, these two practices are unsafe. After watching TV, you should unplug the power cord while turning off the power supply, which can effectively prevent the TV from being struck by lightning in the human room. Similarly, all electrical appliances should be unplugged after use.

Electrical equipment must be placed in a dry, clean and ventilated place. It is best to electrify and heat electrical equipment once a week for a long time to prevent fainting, moisture and rust. Many people like to wipe the surface of TV screen with a wet rag when watching TV. This is not correct. Never wipe household appliances with a wet rag when electricity is on. It is best to adjust the electrical equipment to the energy-saving state, the air conditioning temperature should not be too low, and the number of refrigerator doors should be reduced as much as possible. Don't be too bright on TV or computer.

In summer, people are prone to sweating, so their resistance is correspondingly reduced, and the safety factor against electric shock is relatively weakened. Therefore, more attention should be paid to safety when touching electrical equipment to avoid electric shock accidents. If you find abnormal noise, smell, smoke, fire, etc. When, should immediately disconnect the power.

5. What are the basic common sense of safe electricity use?

1. It is forbidden to move running household appliances by hand, such as desk fans, washing machines, televisions, etc.

2. It is forbidden to repair live lines or equipment at home by hand.

3. It is forbidden to touch with wet hands and wipe lamps, switches and other electrical appliances with wet cloth.

4. It is forbidden to change the three-eye plug into two-eye plug at will.

5. It is forbidden to pull and connect wires indiscriminately.

6. Without permission, it is forbidden to install electrical appliances on the original line.

7. Unqualified electrical equipment is strictly prohibited.

8. It is forbidden to use electric irons, hair dryers, electric stoves and other electrical appliances without supervision.

9. Fishing, theft prevention and hunting in private power grids are prohibited.

10. It is forbidden to use lead wire and copper wire instead of fuse as fuse. Wait a minute.

6. Common sense of safe electricity use

1. Why does the lighting switch have to be connected to the live wire? If the lighting switch is installed on the zero line, although the light is not on when it is turned off, the phase line of the lamp holder is still on, and people will think that the light is not on and will mistakenly think that it is in a power-off state.

In fact, the ground voltage of each point on the lamp is still a dangerous voltage of 220 volts. If people touch these actually charged parts when turning off the lights, it will cause an electric shock accident.

Therefore, all kinds of lighting switches or switches of single-phase small-capacity electrical equipment can only be connected in series on the live line to ensure safety. 2. How to correctly install the single-phase three hole socket? Why? Usually, single-phase electrical equipment, especially mobile electrical equipment, should use three-core plug and its supporting three hole socket.

There is a special protective zero (grounding) jack in three hole socket. When using zero protection, it is very dangerous for someone to directly connect the wiring pile head of this hole with the zero line that only leads into the socket at the bottom of the socket. Because in case the zero line of the power supply is disconnected, or the fire (phase) line and the zero line of the power supply are connected reversely, its shell and other metal parts will also bring the same voltage as the power supply, resulting in electric shock.

Therefore, when wiring, the special grounding jack should be connected with the special protective grounding wire. When zero protection is adopted, the zero line should be led out from the power supply side, and the zero line introduced into the socket should not be used nearby.

3. Why is it forbidden to bury plastic insulated wires directly in the wall? (1) Plastic insulated conductor will age and crack after long-term use, and the insulation level will be greatly reduced. When the line is overloaded or short-circuited, it is easier to accelerate the insulation damage. (2) Once the wall is damp, it will cause a large area of leakage and endanger personal safety.

(3) Plastic insulated wires are directly buried, which is not conducive to line maintenance and repair. 4. Why should I use a leakage protector? Leakage protector, also known as leakage protection switch, is a new type of electrical safety device. Its main purpose is: (1) to prevent electric shock accidents caused by leakage of electrical equipment and electrical lines.

(2) To prevent single-phase electric shock accidents in the process of electricity utilization. (3) Cut off the single-phase grounding fault in the operation of electrical equipment in time to prevent electrical fire accidents caused by leakage.

(4) With the improvement of people's living standards, the number of household appliances is increasing. In the process of using electricity, personal electric shock and fire accidents caused by defects in electrical equipment, improper use and unfavorable safety technical measures have brought undue losses to people's lives and property. The appearance of leakage protector provides a reliable and effective technical means for preventing all kinds of accidents, cutting off power supply in time and protecting equipment and personal safety. 5. What is the main cause of electric shock accident? Statistics show that the main causes of electric shock accidents are: (1) lack of knowledge about electricity safety, flying kites near high-voltage lines and climbing high-voltage poles to dig nests; After the low-voltage overhead line is disconnected, connect the fire line by hand without power failure; Touch the charged body by hand for live wiring at night; Touch the broken rubber knife switch with your hand.

(two) in violation of the operating rules, without taking necessary safety measures, unauthorized connection of lines or electrical equipment; Touch damaged equipment or wires; Wrong installation of live equipment; Electrified lighting; Online maintenance of power tools; Live mobile electrical equipment; Twist a light bulb, etc with wet hands. (3) The equipment is unqualified and the safety distance is not enough; The grounding resistance of two-wire and one-ground system is too large; The grounding wire is unqualified or disconnected; Insulation damage to wires, etc.

(4) The equipment is in disrepair, the line is blown off by strong wind or the pole is not repaired in time; Rubber breaker bakelite is damaged and not replaced in time; The damage of the motor lead makes the shell charged for a long time; The porcelain bottle is damaged, which makes the phase wire and the pull wire short-circuited, and the equipment shell is charged. (5) Due to other accidental reasons, I walked at night and ran into a broken live wire on the ground.

6. What rescue measures should be taken in case of electric shock? When an electric shock accident occurs, while ensuring the rescuer's own safety, we must first try to make the electric shock victim quickly get rid of the power supply, and then carry out the following emergency repair work. (1) Untie the tight clothes that hinder the breathing of the electrocuted person.

(2) Check the mouth of the person who gets an electric shock and clean up the mucus in the mouth. If there are any dentures, remove them. (3) immediately on-site rescue. If breathing stops, rescue with mouth-to-mouth artificial respiration. If the heart stops beating or vibrates irregularly, use artificial chest compression to rescue it.

Never interrupt for no reason. If there is a second person besides the rescuer at the scene, the following work should be done immediately: 1) Provide first aid tools and equipment.

2) convince others at the scene. 3) Keep sufficient lighting and air circulation at the site.

4) Report to the leader and ask the doctor to come to the rescue. Experimental research and statistics show that 90% patients can be saved if treatment is started from 1 min after electric shock. Only 10% chance can save lives if rescue is started 6 minutes after electric shock; But from 12 minutes after electric shock, the possibility of saving lives is extremely small.

So if you find someone getting an electric shock, you should race against time and take all possible measures. 7. What measures are there to use electricity safely at home? With the popularization and application of household appliances, it is very important to correctly master the knowledge of safe electricity use and ensure the safety of electricity use.

(1) Don't buy fake and shoddy "three noes" household products. (2) When using household appliances, there should be a complete and reliable power cord plug.

Household appliances with metal shell should be protected by grounding. (3) Switches and fuses cannot be installed on the ground wire and zero wire.

It is forbidden to connect the ground wire to the tap water and gas pipeline. (4) Don't touch the live equipment with wet hands, and don't wipe the live equipment with wet cloth.

(5) Don't connect wires privately, and don't move live equipment casually. (6) When repairing household appliances, you must first disconnect the power supply.

(7) When the power cord of household appliances is damaged, it should be replaced immediately or wrapped with insulating cloth. (8) When household appliances or wires catch fire, disconnect the power supply first, and then put out the fire.

8. How to prevent burning household appliances? The rated voltage of common household appliances is 220 volts, and the normal power supply voltage is around 220 volts. If the voltage in the power supply line rises instantly due to natural disasters such as lightning strike, the zero line of the three-phase unbalanced household line is disconnected due to disrepair, or the phase voltage rises due to human misconnection, the current will increase, and household appliances will burn out due to overheating.

To prevent the burning of household appliances, we should start from the following aspects: First, try to disconnect the power supply when the electrical equipment is not in use; The second is to transform the old and disrepair.

7. What is the common sense of safe electricity use?

1. Touch and probe the inside of the power socket without hands or conductive objects (such as wires, nails, pins and other metal products); Don't touch wires without insulation; Contact the maintenance personnel in time if you find a thread with * * * *.

2. Don't touch the appliance with wet hands or wipe it with wet cloth. When water leakage is found around the electrical appliance, it should be temporarily stopped, and the maintenance personnel should be immediately notified to do insulation treatment, and then it can be resumed after the water leakage is eliminated. Avoid using electrical appliances in humid environment (such as toilet), and don't let electrical appliances get damp, damp or soak in water, so as to avoid personal injury caused by electric leakage.

3. Electric appliances such as electric light bulbs, hair dryers, rice cookers, electric irons and electric heaters will emit high heat during use. Pay attention to keep them away from flammable items such as paper and cotton cloth to prevent fire; At the same time, pay attention to avoid burns when using. Do not use high-heat light sources or other electrical appliances in mosquito nets, do not install electric lights in wardrobes, and turn off these electrical appliances when unattended.

4. Don't use multiple appliances on a multi-port socket at the same time. The place where the socket is used should be kept dry, and the socket wire should not be wound on the metal pipe. The extension cord shall not pass through the carpet or wall hung with flammable materials, nor shall it be placed on the iron bed.

5, electrical plug must be plugged in, close contact, don't loose, so as not to generate heat. Unplug the power plug in time after using the electrical appliances; When plugging and unplugging the power plug, pinch the plug tightly, and don't pull the wire hard to prevent the insulation layer of the wire from being damaged and causing electric shock; The insulation layer of the wire is peeling off, so it is necessary to replace the wire in time or wrap it with insulating tape. When an electrical appliance trips during use, you must unplug the power plug first, then contact the maintenance personnel to find out the cause of the trip, and check the electrical appliance fault before determining whether it can be used continuously to ensure safety.

6. In case of thunderstorm, stop using computers and televisions and unplug outdoor antennas to prevent lightning strikes. Electrical appliances are easy to be damaged by moisture and corrosion after being put aside for a long time, so they need to be carefully checked before being reused. When purchasing electrical products, you should choose qualified products with recognized quality. It is necessary to eliminate aging electrical appliances in time, and it is strictly forbidden to extend the service of electrical appliances.

7. Don't disassemble or install the power cord, socket and plug at will. Do not destroy public electrical equipment such as safety indicator lights in the building. Power consumption should not exceed the allowable load capacity of wires and circuit breakers. When adding large electrical appliances, it should be checked and approved by professionals, and large circuit breakers should not be replaced without permission, so as to avoid inadequate protection and fire.

8. Don't hang clothes on the wires, and don't wrap metal wires (such as iron wire, aluminum wire and copper wire) on live wires to prevent insulation wear and leakage, causing casualties. Stay away from high-voltage poles, do not fly kites or shoot birds near power lines, and do not dig holes and borrow soil near cables and stay wires to prevent poles from breaking.

9. If you see a broken wire, don't go near it, and report it to the relevant professional department for maintenance in time. In case of power failure of electrical equipment, the maintenance personnel shall be notified in time for repair.

10, when electrical appliances are burnt out or the circuit is overloaded, there are usually some abnormal phenomena, such as smoking, sparking, making strange noises, or overheating the conductor, or even burning to produce pungent smell. At this time, you should immediately cut off the power supply, then check the electrical appliances and circuits, and find maintenance personnel to deal with them.

1 1. When electrical appliances or circuits are on fire, be sure to keep calm. First, cut off the power supply as soon as possible, or turn off the main brake of the indoor circuit, and then aim at the fire with a special fire extinguisher. If there is no special fire extinguisher around, you can put out the fire in a conventional way under the premise of power failure; If the power supply is not cut off, never put out the fire with water or wet things to avoid electric shock.

12, someone get an electric shock immediately turn off the power supply; Or use a dry wooden stick or other insulation to separate the electric shock victim from the charged conductor, and don't save people directly by hand; If the person who gets an electric shock is unconscious and stops breathing, he should be given artificial respiration immediately, or sent to the hospital for emergency treatment immediately.

The above common sense of safe use of electricity must be mastered in daily life. Pay attention to eliminate hidden dangers, and at the same time, in case of electrical fire or electric shock accident, you can keep up with the crisis in time and deal with it quickly to minimize losses.
