first, the correct use of elevators.
1. when calling the elevator, the passenger only needs to press the call button of the direction to go. do not press the upward and downward direction buttons at the same time so as to prevent the useless car from stopping and reduce the total conveying efficiency of the building elevator. at the same time, this is also to avoid the erroneous operation of the safety device, causing passengers to be trapped in the car and affecting the normal operation of the elevator.
2. when the elevator door is opened, be sure not to put your hands on the door panel to prevent the fingers from being squeezed when the door panel is retracted. when the elevator door is closed, do not put your hand on the edge of the door so as not to affect the closing action or even crush your fingers. when you bring a child, you should use your hand to hold or hold the child in the elevator.
3. when taking the elevator, keep a certain distance from the elevator door. for the sake of safety, when the elevator is running, the elevator door is connected with the hoistway. the relative speed is very fast. if the elevator door fails, passengers near the door can be very dangerous.
4, do not jump in the elevator. many safety protection switches are set on the elevator car. if you jump in the car, the car will be heavily tilted, which may cause the protection switch to move and put the elevator into a protected state. when this happens, the elevator will stop in an emergency, causing the trapezee to be trapped.
5, many people used to enter the door when used to block the body, although there is no danger, but if you press too long, the elevator control part will think that the elevator has a fault. it may alarm or even stop. so the more decent approach is that when you go in, press the open button.
in particular, people need to be reminded that some people stand at the elevator door and block the elevator door. this is very dangerous. because the inside of the elevator is safe, the outside is also safe. but if you stand at the junction of these two spaces, if this time comes up, everyone's saying is called opening the door and the person will be cut. so this is a very dangerous place. it should not stay at this junction.
6. some units use a freight elevator as a passenger elevator.
the difference between a freight elevator and a passenger elevator is its decoration, or its comfort is worse. the vibration and noise indicators did not make special demands. in addition, there is a kind of freight elevator that can never be used as a passenger elevator, that is, it is oversized. because sometimes this kind of product that the factory makes is lighter, it hopes that the car is made a little bigger, so after the approval of the relevant department, this car area is bigger than the standard. if such a freight elevator is used as a passenger elevator, it will be overloaded.
second, the safety knowledge after the accident occurred in the elevator.
1. in the event of a fall, the first thing is to fix your own body. when such an impact occurs, it will not cause a fall due to an unstable center of gravity. the second is the use of elevator walls as a protection for the spine and close to the walls, which can play a protective role. most importantly, knee bending can be used to withstand heavy blow pressure. this is because ligaments are the only tissues in the body that are rich in elasticity and are more able to withstand stress than bones. therefore, the back is close to the inner wall of the elevator, the knees are bent, and the protection of the toes is correct.
2. in the case of elevators, the car of the elevator will run down until it is completely out of control, until it stops at the buffer of the pit. this kind of situation rarely happens, but once the consequences are very serious, the huge inertia may lead to life-threatening fractures of the passengers. in fact, if the elevator suddenly drops rapidly during the descent, the safety protection device of the elevator will stop the elevator. it is worth noting that the distance from the start of the elevator to the stop of the elevator is related to the load of the elevator, so the elevator must not be overloaded.
3. self-rescue measures trapped in the elevator. after the emergency stop operation, the elevator has several sets of reliable protective devices to protect the safety of the passengers, without worrying that it will continue to fall down. there are many reasons for sudden stoppages. before you know the reasons, any behavior that you try to escape is a risky move. when you have just been trapped, if there is no alarm call in the elevator, you can slap the door or knock on the door with your shoes. if you are trapped for a long time, the safest thing to do is to stay calm, save your strength, and wait for help.
4. how should elevator management personnel rescue trapped people? when an elevator accident occurs, the elevator manager contacts the trapped passenger by telephone or by shouting. be sure to keep it calm and wait patiently for the assistance of the maintenance staff. when the car is far away from the elevator landing, it enters the engine room to turn off the elevator power switch, installs the disc rider wheel on the elevator shaft, one person tries hard to hold the disc rider's wheel, and the other person holds the brake release lever and gently opens the brake. pay attention to the leveling sign and move the car to the nearest hall door. when it is confirmed that the brake is correct, use the landing door key to open the landing door and the car door to assist passengers to leave the car and reclose the hall door.
it is worth noting that some elevator workers directly open the elevator's inner or outer doors. then lean on, and sometimes jump on the landing floor, which is very common in life. however, this is a very unconscionable rescue action because the elevator stops at a position where it should not stop, indicating that the system has failed. then if you open the door without shutting off the power, in case the elevator fails again, passengers will be in danger.
