Hunan ElevatorUse safety knowledge, home must keep in mind!
In today's elevator and people's lives have been inseparable, its safety issues are also related to the vital interests of each of us and received more and more attention。Changsha Alpha elevator for home finishing, elevator use safety knowledge, home must keep in mind!
A few days ago, the people of Huzhou deliberated and passed the "Huzhou Elevator Safety Regulations", which is the second local regulation of Huzhou after the "Huzhou Ban on the sale of fireworks", and was officially implemented on April 1。
The elevator will suddenly drop while it is in motion?
Many people worry that the elevator will suddenly fall during operation, but in fact, "elevator fall" is not really falling。
There are usually two situations when the elevator falls:
Emergency stop during elevator operation: the safety circuit or door lock circuit is disconnected during operation, causing the elevator to stop, and passengers feel numbness in their legs, which is actually caused by the emergency stop of the elevator。
If the elevator fails during operation, it will automatically return to the base station to reset: that is, the "elevator falls" that is misunderstood by some people, and the probability of this happening is almost the same as the probability of buying 5 million in the lottery。
The elevator suddenly fell because the wire rope broke？
Some articles on the Internet explain: "The sudden fall in the lift-like situation is caused by the break of the rope that pulls the elevator."。
In fact, the elevator wire rope is not so fragile。The elevator car is pulled by the wire rope, the more the load, the more the wire rope。For elevators in general residential buildings, there are at least 3 steel cables, each steel wire rope has about 10 steel strands, and each steel strand has 10 steel wires。In principle, as long as the strand is broken, all the rope needs to be replaced。
In theory, a wire rope can withstand all the gravity of the elevator car。So you don't have to worry about the car falling with the roots。Moreover, the probability of the rope breaking is really very high。
Get stuck in an elevator and open the door？
Opening the door to save oneself is equivalent to finding a short circuit!In addition to calling rescue, call the elevator maintenance company, press the alarm button inside the elevator, do not want to open the door to save yourself, there are many examples of self-rescue failure leading to casualties, do not go to the next。
You suffocate when you're stuck in an elevator？
The elevator car is not an enclosed space and does not pose a choking hazard
An article said: "If you are trapped in the elevator, you must first calm down, because in the limited space of the elevator, the amount of oxygen is also limited, the body consumes less oxygen when calm, so try to keep calm, you can make the trapped person will not suffocate due to hypoxia in a short time.。”
National standard for elevator ventilation requirements
According to the national standard "GB7588-2003 elevator Manufacturing and Installation safety Code" the following relevant provisions:
5.2.3 Ventilation of the well
The well should be properly ventilated, and the well should not be used for ventilation of non-elevator rooms。
Note: In the absence of relevant codes or standards, it is recommended that the vent area at the top of the well be at least 1% of the cross-sectional area of the well。
8.16 通风
8.16.1 The car with a non-porous door shall be provided with ventilation holes in its upper and lower parts。
8.16.The effective area of both the upper and lower vent holes of the car should not be 1% of the effective area of the car。The clearance around the car door can be taken into account when calculating the area of the vent, but it must not be 50% of the required effective area。
8.16.3 The ventilation hole should be set up in this way: with a hard straight rod with a diameter of 10mm, it is impossible to pass through the car wall from the car through the ventilation hole。
In fact, the elevator car is not an enclosed space and does not pose a choking hazard。But keep your cool。
